Definitions
- the present invention relates to a lead, and in particular, to an implantable lead and a method of manufacturing such lead.
- Implantable leads having ring electrodes can be used in a variety of applications, including delivery of electrical stimulation to surrounding tissue, neural or otherwise, as well as measuring electrical energy produced by such tissue. Whether serving in a stimulation capacity or a sensing capacity, such leads are commonly implanted along peripheral nerves, within the epidural or the intrathecal spaces of the spinal column, about the heart, and in the brain.
- an isodiametric lead can reduce the potential for damage to the lead during insertion (for example, when a lead is passed through an insertion needle to reach a patient epidural space) and/or placement, improve the ability of the lead to pass through tissue or a vascular system, and is more resistant to being immobilized by tissue growth at a permanent implantation site.
- Differing techniques have been used to produce isodiametric leads.
- One such technique concerns adhering a plurality of elements (i.e., conductive electrodes, conductive terminals, and spacing insulative tubing material) to produce a generally integral body.
- Tubing material separates a stimulation/sensing portion (i.e., alternating insulative tubing material and electrodes) from a terminal portion (i.e., alternating insulative tubing material and terminals).
- the electrodes, terminals, and tubing are independently formed but are intended to be isodiametric. Understandably, dimension variances in any one element can result in a lead having a varying diameter.
- a composition for example, medical grade epoxy, is injected within an interior of the leads in and about the stimulation/sensing portions and the terminal portions. While this technique does typically effect stabilization and strengthening of these critical regions, the end result can also be that these regions are too rigid and even brittle.
- a ring electrode(s) about an exterior surface of insulative tubing that forms the main body of the lead.
- the insulative tubing may be prepared to receive the electrode, for example, milled to remove an amount of material substantially equal to the material thickness of the ring electrode.
- the insulative tubing may be unprepared, for example, a ring electrode is simply “crimped” to a diameter substantially equal to the otherwise unadulterated diameter of the tubing.
- a finished lead is still comprised of a plurality of independent components brought together in an effort to form an isodiametric cross-section.
- Element misalignment, inaccuracies in grinding, variances in electrode material thickness or individual element dimensions, or over/undercrimping could respectively result in at least undesirable variances in lead diameter.
- One aspect of the present invention is directed to an implantable lead including a lead body, having a distal end and a proximal end, whereas the lead body is formed of a material having prescribed mechanical properties.
- a first region includes a plurality of electrodes.
- a first insulative material having mechanical properties consistent with the material of the lead body, separates adjacent electrodes.
- a second region includes at least one terminal.
- a second insulative material having mechanical properties consistent with the material of the lead body, separates adjacent terminals.
- a conductor couples each terminal to at least one corresponding electrode of the plurality of electrodes, wherein the conductor(s) extends along an interior passage defined by the lead body, first region, and second region.
- the interior passage of the first region is substantially filled with a third insulative material having mechanical properties consistent with the material of the lead body.
- Another aspect of the present invention concerns a method of forming a substantially isodiametric lead.
- such lead has a prescribed diameter and includes at least one electrode separated from at least one terminal by a lead body, wherein the at least one electrode is electrically coupled to the at least one terminal by a conductor passing through a passage defined by at least the lead body.
- the forming steps include assembling the at least one electrode and the at least one terminal relative to the lead body to form an assembly, including connecting the at least one electrode to the at least one terminal via the conductor.
- the assembly is subjected to an over-molding process that over molds the assembly with a first material to form an intermediate assembly. This first material is compatible with and has mechanical properties consistent with a material of the lead body.
- the intermediate assembly is processed to remove all material of the intermediate assembly in excess of the prescribed diameter.
- An object of the present invention is to avoid the shortcomings of known leads and manufacturing techniques for the same.
- Another object of the present invention is to provide a method of forming a lead having a true isodiametric body for at least the stimulation/sensing portion of the lead.
- Another object of the present invention is to provide a lead having a true isodiametric body for at least the stimulation/sensing portion of the lead.

- FIG. 1 illustrates a preferred embodiment of multi-electrode lead 10 . While the leads illustrated and generally discussed here have eight electrodes, lead 10 of the present invention may be constructed having any number of electrodes (i.e., one or more).
- Lead 10 includes a proximal end 12 and a distal end 14 .
- the proximal end 12 includes a plurality of electrically conductive terminals 16
- the distal end 14 includes a plurality of electrically conductive electrodes 18 . While typically each terminal 16 is electrically connected to a single electrode 18 via a conductor 20 (FIG. 3), a terminal 16 can be connected to two or more electrodes 18 .
- Terminals 16 and electrodes 18 are preferably formed of a non-corrosive, highly conductive material. Examples of such material include stainless steel, MP35N, platinum, and platinum alloys. In a preferred embodiment, terminals 16 and electrodes 18 are formed of a platinum-iridium alloy.
- body 22 Spanning between electrodes 18 of the distal end 14 and terminals 16 of the proximal end 12 , body 22 is formed from a medical grade, substantially inert material, for example, polyurethane, silicone, or the like. While the specific material used for body 22 is not critical to the present invention, body 22 must be non-reactive to the environment of the human body, provide a flexible and durable (i.e., fatigue resistant) exterior structure for the components of lead 10 , and insulate adjacent terminals 16 and/or electrodes 18 .
- a medical grade, substantially inert material for example, polyurethane, silicone, or the like. While the specific material used for body 22 is not critical to the present invention, body 22 must be non-reactive to the environment of the human body, provide a flexible and durable (i.e., fatigue resistant) exterior structure for the components of lead 10 , and insulate adjacent terminals 16 and/or electrodes 18 .
- body 22 substantially provides the exterior structure that contains the internalized elements of lead 10 . Specifically, body 22 provides an enclosure for each conductor 20 that connects a terminal 16 with one or more electrodes 18 .
- Each conductor 20 is formed of a conductive material that exhibits the desired mechanical properties of low resistance, corrosion resistance, flexibility, and strength. For consideration, however, it should be appreciated that in the context of a multiple electrode lead 10 , a plurality of conductors 20 are required to fit within the interior of body 22 . Accordingly, the cross-sectional area of each conductor 20 is restricted. As but one example, for a lead in accordance with the present invention that has an outer diameter of approximately 0.055 inches, conductor 20 could be on the order of approximately 0.0065 inches.
- conductors 20 utilizes wires formed of multi-strands of drawn-filled tubes (DFT), as illustrated in FIG. 4.
- DFT drawn-filled tubes
- Each strand is formed of a low resistance material 20 a and is encased in a high strength material 20 b (preferably, metal).
- a selected number of strands are wound and coated with an insulative material 20 c.
- insulative material 20 c protects the individual conductors 20 if body 22 were breached during use.
- Wire formed of multi-strands of drawn-filled tubes to form conductors 20 is available from Temp-Flex Cable, Inc. (City, State).
- conductors 20 formed of multi-strands of drawn-filled tubes provide a low resistance alternative to other conventional materials.
- a stranded wire, or even coiled wire, of approximately 60 cm and formed of MP35N or stainless steel or the like would have a measured resistance in excess of 30 ohms.
- a wire formed of multi-strands of drawn-filled tubes, as illustrated in FIG. 4 could have a resistance less than 4 ohms.
- each conductor 20 having a length equal to or less than 60 cm, has a resistance of less than 25 ohms.
- each conductor 20 having a length equal to or less than 60 cm, has a resistance equal to or less than 10 ohms. In a most preferred embodiment, each conductor 20 , having a length equal to or less than 60 cm, has a resistance of less than 4 ohms.
- body 22 can further encompass stylet tubing 24 (FIG. 3).
- Stylet tubing 24 extends from the proximal end 12 to a point within a distal portion of lead 10 ; however, in a preferred embodiment, stylet tubing 24 extends to cap electrode 34 .
- stylet tubing 24 operatively receives stylet 100 for purposes of allowing better control over lead 10 during placement.
- a lead in accordance with the present invention may have more than or less than eight electrodes and/or have a larger or smaller diameter than the following example and remain within the scope of this disclosure.
- stylet tubing 24 is positioned over mandrel 150 .
- Stylet tubing 24 has an outer diameter of approximately 0.02 inches.
- FIG. 11 illustrates an example of a fixture 200 that can assist in this task.
- fixture 200 includes first rotary clamp 202 , iris 204 , iris 206 , second rotary clamp 208 , and clamp 210 .
- Rotary clamps 202 and 208 each include a corresponding plurality of conductor clamps 203 . While not required, it is preferred that the plurality of conductor clamps 203 of each rotary claim 202 and 208 be positioned within an arbitrary perimeter 205 , whereas perimeter 205 should be equal to or greater than a fully-opened inner diameter of either iris 204 or 206 .
- mandrel 150 passes through irises 204 and 206 and second rotary clamp 208 and is secured between clamps 202 and 210 .
- Each conductor 20 similarly passes through irises 204 and 206 and is secured between respective clamps 203 of rotary clamps 202 and 208 .
- Conductors 20 secured within fixture 200 are prepared for assembly in that a prescribed amount of insulative material 20 c is removed at or about the proximal and distal ends of each conductor 20 to expose conductive material 20 a and 20 b. As will be discussed later, this exposed conductive material 20 a and 20 b of the proximal and distal ends of each conductor 20 is eventually joined to an electrode 18 and a terminal 16 . Accordingly, the exposed conductive material 20 a and 20 b is arranged at differing positions relative to stylet tubing 24 to accommodate the serial arrangement of terminals 16 and electrodes 18 .
- rotary clamps 202 and 208 provide unobstructed access to the in-process lead 10 . Specifically, upon securing a single conductor 20 between opposing (or non-opposing) clamps 203 , the rotary clamps 202 and 210 are simply rotated to allow access to unoccupied clamps 203 .
- conductor(s) 20 When all of the conductors 20 are strung between claims 202 and 208 , irises 204 and 206 are actuated to close and draw conductor(s) 20 closely about the outer diameter of stylet tubing 24 . When conductor(s) 20 are resting against the outer diameter of stylet tubing 24 , conductor(s) 20 are secured in place. Conductor(s) 20 may be secured using adhesive and/or subjected to a force applied through use of a temporary or permanent restraint, for example, one or more crimped collars.
- FIG. 11 shows but one embodiment of fixture 200
- clamps 203 of each rotary clamp 202 and 208 could be moveable along respective radial paths (not shown) that would allow strung conductors 20 to be moved from a first position to a second position adjacent the exterior surface of stylet tubing 24 .
- conductors 20 could initially be secured to one end of stylet tubing 24 and only a single iris could be used to draw the unsecured portions of conductors 20 toward stylet tubing 24 .
- an operator could simply manipulate the conductor(s) 20 to manually position and secure them relative to stylet tubing 24 .
- transitional element 26 electrode(s) 18 , electrode spacer(s) 28 , outer tubing 23 , terminal spacer(s) 30 , terminal(s) 16 , and stylet guide 32 are positioned over, and concentrically arranged with, stylet tubing 24 .
- the arrangement of these elements is in accordance with that illustrated in FIG. 5.
- Transitional element 26 is illustrated in FIG. 6. As will be discussed later, transitional element 26 provides a platform to receive cap electrode 34 (FIG. 10). Transitional element 26 further provides a durable guide 26 a to direct a distal end (not shown) of stylet 100 to cap electrode 34 via passage 26 b. Transitional element 26 is preferably formed of a conductive material, for example, the same material used to form electrodes 18 .
- Electrode spacer 28 is illustrated in FIG. 7.
- terminal spacer 30 is illustrated in FIG. 8.
- electrode spacer 28 and terminal spacer 30 accurately defines a space between adjacent electrodes 18 and terminals 16 , respectively.
- Electrode spacer 28 and terminal spacer 30 are preferably formed of the same material as outer tubing 23 .
- spacers 28 and 30 may be formed of a material that differs from that of outer tubing 23 ; provided however, any differing material used for electrode spacer 28 and/or terminal spacer 30 must be compatible with and possess largely the same mechanical properties (e.g., non-reactive to the environment of the human body, flexible and durable) as outer tubing 23 .
- spacers 28 and 30 are formed of a polyurethane material, for example, Bionate 75D (Polymer Tech. Group, City, State). As is noted in FIG. 5, spacers 28 and 30 should have an outer diameter greater than lead 10 .
- Outer tubing 23 separates electrodes 18 from terminals 16 .
- outer tubing 23 has a diameter substantially equal to a diameter of lead 10 .
- outer tubing 23 may have a diameter less than lead 10 , or a diameter greater than lead 10 .
- outer tubing 23 must have a wall thickness greater than a differential between a radius of lead 10 and a radius (to the outer diameter) of outer tubing 23 .
- outer tubing 23 has a nominal outer diameter of approximate 0.055 inches.
- Stylet guide 32 is illustrated in FIG. 9.
- Stylet guide 32 provides an inlet to stylet tubing 24 .
- Stylet guide 32 is preferably formed of a conductive material, for example, the same material used to form electrodes 18 .
- Stylet guide 32 , as well as terminals 16 , electrodes 18 , and transitional element 26 preferably each have an outer diameter equal to or greater than a nominal diameter of lead 10 . In a more preferred embodiment, these elements each have an outer diameter greater than a nominal diameter of lead 10 .
- terminals 16 and electrodes 18 are joined to their respective conductors 20 .
- each terminal 16 (and each electrode 18 ) is positioned relative to exposed conductive material 20 a and 20 b of a conductor 20 and is joined in a manner that facilitates a transfer of electrical energy, for example, resistance weld or laser weld.
- stylet guide 32 is secured to a proximal-most terminal 16
- transitional element 26 is secured to a distal-most electrode 18 .
- transitional element 26 and stylet guide 32 are formed a conductive material, these elements may be secured using a process consistent with that used to join terminals 16 and electrodes 18 with conductors 20 . Otherwise, transitional element 26 and stylet guide 32 can be joined using an adhesive, cement or the like.
- the completed assembly (FIG. 5) is then over-molded, using well known injection molding techniques, using a material having mechanical properties consistent with a material(s) used to form outer tubing 23 , electrode spacer 28 , and terminal spacer 30 .
- the over-molding material and the material of outer tubing 23 , electrode spacer 28 , and terminal 28 are the same.
- Electrode spacers 28 and terminal spacers 30 are placed in a state of flow, which, at least in part, results in a filling of regions between terminals 16 /electrodes 18 and stylet guide 24 . Consequently, terminals 16 and electrodes 18 are partially surrounded (i.e., along an interior surface) and supported by a fused matrix of material.
- electrode spacers 28 and terminal spacers 30 are formed of a material mechanically equivalent to that of body 22 /outer tubing 23 , the stimulation/sensing portion and terminal portion of lead 10 are stabilized and strengthened while also retaining their flexible properties.
- the over-molded assembly (not shown) is then subjected to a grinding process to remove all excess material.
- the over-molded assembly is subject to centerless grinding, wherein excessive material, including over-molded material, electrode material, terminal material, and the like, is removed.
- an isodiametric lead is obtained, which is further free of any gaps or voids between insulative material and conductive material that may otherwise exist in conventional devices.
- cap electrode 34 is affixed to transitional element 26 using conventional means, for example, resistance welding, laser welding, or the like.

Abstract
An implantable, substantially isodiametric, low resistance implantable lead having at least one electrode positioned in a stimulation/sensing portion of the lead as well as a method of manufacturing the same. At least the stimulation/sensing portion is unitized through partially surrounding and supporting insulation and conductive element(s) of the stimulation/sensing portion with a fused matrix of material having mechanical properties consistent with a body of the lead.
Description
- This is a division of U.S. patent application Ser. No. 09/299,702, filed Apr. 26, 1999, pending.
- The present invention relates to a lead, and in particular, to an implantable lead and a method of manufacturing such lead.
- Implantable leads having ring electrodes can be used in a variety of applications, including delivery of electrical stimulation to surrounding tissue, neural or otherwise, as well as measuring electrical energy produced by such tissue. Whether serving in a stimulation capacity or a sensing capacity, such leads are commonly implanted along peripheral nerves, within the epidural or the intrathecal spaces of the spinal column, about the heart, and in the brain.
- Notwithstanding the application, the common requirements for such implantable leads include flexibility, strength, and durability. The extent of such qualities, of course, is dependent upon the nature of the use, for example, temporary or permanent implantation. While material selection and certain construction techniques can be tailored to assist in meeting these prescribed characteristics, an overriding consideration in the design of such leads is achieving at least an isodiametric stimulation/pacing portion thereof.
- The benefits of achieving desired levels of flexibility, strength, and durability are intuitive. The isodiametric characteristic is likely less obvious. Depending upon the application, an isodiametric lead can reduce the potential for damage to the lead during insertion (for example, when a lead is passed through an insertion needle to reach a patient epidural space) and/or placement, improve the ability of the lead to pass through tissue or a vascular system, and is more resistant to being immobilized by tissue growth at a permanent implantation site.
- Differing techniques have been used to produce isodiametric leads. One such technique concerns adhering a plurality of elements (i.e., conductive electrodes, conductive terminals, and spacing insulative tubing material) to produce a generally integral body. Tubing material separates a stimulation/sensing portion (i.e., alternating insulative tubing material and electrodes) from a terminal portion (i.e., alternating insulative tubing material and terminals). The electrodes, terminals, and tubing are independently formed but are intended to be isodiametric. Understandably, dimension variances in any one element can result in a lead having a varying diameter.
- Of further interest, to strengthen the plurality of element interfaces found in the stimulation/sensing portions and terminal portions of these leads, a composition, for example, medical grade epoxy, is injected within an interior of the leads in and about the stimulation/sensing portions and the terminal portions. While this technique does typically effect stabilization and strengthening of these critical regions, the end result can also be that these regions are too rigid and even brittle.
- Other techniques include applying a ring electrode(s) about an exterior surface of insulative tubing that forms the main body of the lead. The insulative tubing may be prepared to receive the electrode, for example, milled to remove an amount of material substantially equal to the material thickness of the ring electrode. Alternatively, the insulative tubing may be unprepared, for example, a ring electrode is simply “crimped” to a diameter substantially equal to the otherwise unadulterated diameter of the tubing.
- For all of the methods described above, a finished lead is still comprised of a plurality of independent components brought together in an effort to form an isodiametric cross-section. Element misalignment, inaccuracies in grinding, variances in electrode material thickness or individual element dimensions, or over/undercrimping could respectively result in at least undesirable variances in lead diameter.
- Accordingly, a need exists for a lead, as well as a method of fabricating such lead, that provides a requisite level of flexibility, strength, and durability, while further providing a true isodiametric body for at least the stimulation/sensing portion of the lead.
- One aspect of the present invention is directed to an implantable lead including a lead body, having a distal end and a proximal end, whereas the lead body is formed of a material having prescribed mechanical properties. Extending from the distal end of the lead body, a first region includes a plurality of electrodes. A first insulative material, having mechanical properties consistent with the material of the lead body, separates adjacent electrodes. Extending from the proximal end of the lead body, a second region includes at least one terminal. A second insulative material, having mechanical properties consistent with the material of the lead body, separates adjacent terminals. A conductor couples each terminal to at least one corresponding electrode of the plurality of electrodes, wherein the conductor(s) extends along an interior passage defined by the lead body, first region, and second region. In addition to the at least one conductor, the interior passage of the first region is substantially filled with a third insulative material having mechanical properties consistent with the material of the lead body.
- Another aspect of the present invention concerns a method of forming a substantially isodiametric lead.

- Various embodiments, including preferred embodiments, will now be described in detail below with reference to the drawings.
- FIG. 1 illustrates a preferred embodiment of
multi-electrode lead 10. While the leads illustrated and generally discussed here have eight electrodes,lead 10 of the present invention may be constructed having any number of electrodes (i.e., one or more). -
Lead 10 includes aproximal end 12 and adistal end 14. Theproximal end 12 includes a plurality of electricallyconductive terminals 16, and thedistal end 14 includes a plurality of electricallyconductive electrodes 18. While typically each terminal 16 is electrically connected to asingle electrode 18 via a conductor 20 (FIG. 3), a terminal 16 can be connected to two ormore electrodes 18. -
Terminals 16 andelectrodes 18 are preferably formed of a non-corrosive, highly conductive material. Examples of such material include stainless steel, MP35N, platinum, and platinum alloys. In a preferred embodiment,terminals 16 andelectrodes 18 are formed of a platinum-iridium alloy. - Spanning between
electrodes 18 of thedistal end 14 andterminals 16 of theproximal end 12,body 22 is formed from a medical grade, substantially inert material, for example, polyurethane, silicone, or the like. While the specific material used forbody 22 is not critical to the present invention,body 22 must be non-reactive to the environment of the human body, provide a flexible and durable (i.e., fatigue resistant) exterior structure for the components oflead 10, and insulateadjacent terminals 16 and/orelectrodes 18. - Serving as a sheath,
body 22 substantially provides the exterior structure that contains the internalized elements oflead 10. Specifically,body 22 provides an enclosure for eachconductor 20 that connects a terminal 16 with one ormore electrodes 18. Eachconductor 20 is formed of a conductive material that exhibits the desired mechanical properties of low resistance, corrosion resistance, flexibility, and strength. For consideration, however, it should be appreciated that in the context of amultiple electrode lead 10, a plurality ofconductors 20 are required to fit within the interior ofbody 22. Accordingly, the cross-sectional area of eachconductor 20 is restricted. As but one example, for a lead in accordance with the present invention that has an outer diameter of approximately 0.055 inches,conductor 20 could be on the order of approximately 0.0065 inches. - While stranded bundles of stainless steel, MP35N, platinum, platinum-iridium alloy, drawn-brazed silver (DBS) or the like can be used, the preferred embodiment of
conductors 20 utilizes wires formed of multi-strands of drawn-filled tubes (DFT), as illustrated in FIG. 4. Each strand is formed of alow resistance material 20 a and is encased in ahigh strength material 20 b (preferably, metal). A selected number of strands (seven, for this example) are wound and coated with aninsulative material 20 c. With regard to the operating environment of the present invention,insulative material 20 c protects theindividual conductors 20 ifbody 22 were breached during use. Wire formed of multi-strands of drawn-filled tubes to formconductors 20, as discussed here, is available from Temp-Flex Cable, Inc. (City, State). - In addition to providing the requisite strength, flexibility, and resistance to fatigue,
conductors 20 formed of multi-strands of drawn-filled tubes, in accordance with the preferred embodiment, provide a low resistance alternative to other conventional materials. Specifically, a stranded wire, or even coiled wire, of approximately 60 cm and formed of MP35N or stainless steel or the like would have a measured resistance in excess of 30 ohms. In contrast, for the same length, a wire formed of multi-strands of drawn-filled tubes, as illustrated in FIG. 4, could have a resistance less than 4 ohms. Accordingly, in a preferred embodiment, eachconductor 20, having a length equal to or less than 60 cm, has a resistance of less than 25 ohms. In a more preferred embodiment, eachconductor 20, having a length equal to or less than 60 cm, has a resistance equal to or less than 10 ohms. In a most preferred embodiment, eachconductor 20, having a length equal to or less than 60 cm, has a resistance of less than 4 ohms. - As an alternative embodiment,
body 22 can further encompass stylet tubing 24 (FIG. 3).Stylet tubing 24 extends from theproximal end 12 to a point within a distal portion oflead 10; however, in a preferred embodiment,stylet tubing 24 extends to capelectrode 34. In cooperative reference to FIG. 2,stylet tubing 24 operatively receivesstylet 100 for purposes of allowing better control overlead 10 during placement. - LEAD ASSEMBLY
- While the following discussion provides but one example of a sequence of steps to form a lead similar to that illustrated in FIGS. 2 and 3. One having ordinary skill in this art shall appreciate that the following steps may be performed in a differing order or otherwise inconsequentially modified to still yield the present invention. Consequently, such minor variations are still regarded as being within the scope of the present invention and should be construed in such manner.
- Furthermore, for purposes of illustration, the following example includes certain physical dimensions to illustrate the relationship between elements as well as effects of differing processes. Accordingly, the provided physical dimensions are used merely for example and shall not restrict the scope of the present invention.
- The following illustrative example concerns the construction of an eight electrode, epidural lead that accommodates a stylet. One skilled in the art shall appreciate, however, that a lead in accordance with the present invention may have more than or less than eight electrodes and/or have a larger or smaller diameter than the following example and remain within the scope of this disclosure.
- In reference to FIG. 5,
stylet tubing 24 is positioned overmandrel 150.Stylet tubing 24 has an outer diameter of approximately 0.02 inches. - Depending on the quantity of
conductors 20 required (e.g., for this illustration, eight) and the size (i.e., diameter) ofsuch conductors 20, arranging and securingconductors 20 can be problematic when they are being arranged and secured about an element having the dimensions ofstylet tubing 24. - While any number of techniques may be used to achieve such arrangement of
conductors 20 relative tostylet tubing 24, FIG. 11 illustrates an example of a fixture 200 that can assist in this task. Specifically, fixture 200 includes firstrotary clamp 202,iris 204,iris 206, secondrotary clamp 208, and clamp 210. Rotary clamps 202 and 208 each include a corresponding plurality of conductor clamps 203. While not required, it is preferred that the plurality of conductor clamps 203 of eachrotary claim arbitrary perimeter 205, whereasperimeter 205 should be equal to or greater than a fully-opened inner diameter of eitheriris - As illustrated,
mandrel 150, includingstylet tubing 24, passes throughirises rotary clamp 208 and is secured betweenclamps conductor 20 similarly passes throughirises respective clamps 203 of rotary clamps 202 and 208. -
Conductors 20 secured within fixture 200 are prepared for assembly in that a prescribed amount ofinsulative material 20 c is removed at or about the proximal and distal ends of eachconductor 20 to exposeconductive material conductive material conductor 20 is eventually joined to anelectrode 18 and a terminal 16. Accordingly, the exposedconductive material stylet tubing 24 to accommodate the serial arrangement ofterminals 16 andelectrodes 18. - The rotational nature of rotary clamps202 and 208 provides unobstructed access to the in-
process lead 10. Specifically, upon securing asingle conductor 20 between opposing (or non-opposing) clamps 203, the rotary clamps 202 and 210 are simply rotated to allow access tounoccupied clamps 203. - When all of the
conductors 20 are strung betweenclaims irises stylet tubing 24. When conductor(s) 20 are resting against the outer diameter ofstylet tubing 24, conductor(s) 20 are secured in place. Conductor(s) 20 may be secured using adhesive and/or subjected to a force applied through use of a temporary or permanent restraint, for example, one or more crimped collars. - While the illustration of FIG. 11 shows but one embodiment of fixture200, one skilled in the art should appreciate that other techniques/structures may be employed to position
conductors 20 adjacent an exterior surface ofstylet tubing 24. Specifically, clamps 203 of eachrotary clamp conductors 20 to be moved from a first position to a second position adjacent the exterior surface ofstylet tubing 24. Alternatively,conductors 20 could initially be secured to one end ofstylet tubing 24 and only a single iris could be used to draw the unsecured portions ofconductors 20 towardstylet tubing 24. As yet another alternative, while the various alternatives offered provide some mechanism to control the rate of movement and relative positioning ofconductors 20, an operator could simply manipulate the conductor(s) 20 to manually position and secure them relative tostylet tubing 24. - Once all
conductors 20 are secured tostylet tubing 24,transitional element 26, electrode(s) 18, electrode spacer(s) 28,outer tubing 23, terminal spacer(s) 30, terminal(s) 16, andstylet guide 32 are positioned over, and concentrically arranged with,stylet tubing 24. The arrangement of these elements is in accordance with that illustrated in FIG. 5. -
Transitional element 26 is illustrated in FIG. 6. As will be discussed later,transitional element 26 provides a platform to receive cap electrode 34 (FIG. 10).Transitional element 26 further provides adurable guide 26 a to direct a distal end (not shown) ofstylet 100 to capelectrode 34 viapassage 26 b.Transitional element 26 is preferably formed of a conductive material, for example, the same material used to formelectrodes 18. -
Electrode spacer 28 is illustrated in FIG. 7. Similarly,terminal spacer 30 is illustrated in FIG. 8. Functionally,electrode spacer 28 andterminal spacer 30 accurately defines a space betweenadjacent electrodes 18 andterminals 16, respectively.Electrode spacer 28 andterminal spacer 30 are preferably formed of the same material asouter tubing 23. However,spacers outer tubing 23; provided however, any differing material used forelectrode spacer 28 and/orterminal spacer 30 must be compatible with and possess largely the same mechanical properties (e.g., non-reactive to the environment of the human body, flexible and durable) asouter tubing 23. At least for purposes of this example, spacers 28 and 30 are formed of a polyurethane material, for example, Bionate 75D (Polymer Tech. Group, City, State). As is noted in FIG. 5,spacers lead 10. -
Outer tubing 23separates electrodes 18 fromterminals 16. In a preferred embodiment,outer tubing 23 has a diameter substantially equal to a diameter oflead 10. Alternatively,outer tubing 23 may have a diameter less thanlead 10, or a diameter greater thanlead 10. In regard to the latter alternative,outer tubing 23 must have a wall thickness greater than a differential between a radius oflead 10 and a radius (to the outer diameter) ofouter tubing 23. For this particular example,outer tubing 23 has a nominal outer diameter of approximate 0.055 inches. -
Stylet guide 32 is illustrated in FIG. 9.Stylet guide 32 provides an inlet tostylet tubing 24.Stylet guide 32 is preferably formed of a conductive material, for example, the same material used to formelectrodes 18.Stylet guide 32, as well asterminals 16,electrodes 18, andtransitional element 26, preferably each have an outer diameter equal to or greater than a nominal diameter oflead 10. In a more preferred embodiment, these elements each have an outer diameter greater than a nominal diameter oflead 10. - Following the assembly of each of the elements described above,
terminals 16 andelectrodes 18 are joined to theirrespective conductors 20. Generally, each terminal 16 (and each electrode 18) is positioned relative to exposedconductive material conductor 20 and is joined in a manner that facilitates a transfer of electrical energy, for example, resistance weld or laser weld. Once allterminals 16 andelectrodes 18 are secured,stylet guide 32 is secured to aproximal-most terminal 16, andtransitional element 26 is secured to adistal-most electrode 18. Providedtransitional element 26 andstylet guide 32 are formed a conductive material, these elements may be secured using a process consistent with that used to jointerminals 16 andelectrodes 18 withconductors 20. Otherwise,transitional element 26 and stylet guide 32 can be joined using an adhesive, cement or the like. - The completed assembly (FIG. 5) is then over-molded, using well known injection molding techniques, using a material having mechanical properties consistent with a material(s) used to form
outer tubing 23,electrode spacer 28, andterminal spacer 30. In a preferred embodiment, the over-molding material and the material ofouter tubing 23,electrode spacer 28, and terminal 28 are the same. - This process has the beneficial effect of unitizing the element assembly to form
lead 10. Moreover,electrode spacers 28 andterminal spacers 30 are placed in a state of flow, which, at least in part, results in a filling of regions betweenterminals 16/electrodes 18 andstylet guide 24. Consequently,terminals 16 andelectrodes 18 are partially surrounded (i.e., along an interior surface) and supported by a fused matrix of material. Importantly, aselectrode spacers 28 andterminal spacers 30 are formed of a material mechanically equivalent to that ofbody 22/outer tubing 23, the stimulation/sensing portion and terminal portion oflead 10 are stabilized and strengthened while also retaining their flexible properties. - The over-molded assembly (not shown) is then subjected to a grinding process to remove all excess material. In a preferred process, the over-molded assembly is subject to centerless grinding, wherein excessive material, including over-molded material, electrode material, terminal material, and the like, is removed. Pursuant to the described over-molding and grinding of the entire lead assembly, an isodiametric lead is obtained, which is further free of any gaps or voids between insulative material and conductive material that may otherwise exist in conventional devices.
- Following the grinding process,
cap electrode 34 is affixed totransitional element 26 using conventional means, for example, resistance welding, laser welding, or the like. - While addressed in part above, as the invention has been described herein relative to a number of particularized embodiments, it is understood that modifications of, and alternatives to, these embodiments, such modifications and alternatives realizing the advantages and benefits of this invention, will be apparent to those of ordinary skill in the art having reference to this specification and its drawings. It is contemplated that such modifications and alternatives are within the scope of this invention as subsequently claimed herein, and it is intended that the scope of this invention claimed herein be limited only by the broadest interpretation of the appended claims to which the inventors are legally entitled.
