Refer now to Fig. 6, it illustrates the sectional view of catheter shaft part 105.Catheter shaft 302 is hollow, and is included in the wherein stability line 304 of longitudinal extension.Catheter shaft 302 is preferably by elasticity and durable (robust) material structure (for example a kind of metal or various metals), described material stretch-proof and plastic deformation, keep simultaneously enough flexibilities, to be conducted through zigzag channel and other similar converging ducts.Suitable metal can comprise rustless steel, Nitinol (Nitinol) etc.In some embodiments, polymer pipe respond well, some embodiments for example can be by continuous polymer-extruded manufacturing.These are extruded and also can comprise and interweave to obtain extra intensity and ruggedness, and can be by polymer--for example polyimides--structure.Stability line 304 can be constructed by similar material equally.
In some embodiments, smooth coating or material can be added in stability line 304 or the catheter shaft 302 one or both, and this can help these two parts more mutually to slide through freely, and totally do not have and block or sticking card.For example, polymer (for example PTFE or Parylene) can be applied on the stability line 304.Coating (for example FEP) also can be extruded into stability line.Thermal polycondensation compound (for example PTFE or polyethylene) also can be added into stability line 304.
In some embodiments, preferably, described stability line 304 can be along the vicissitudinous diameter of its length tool.This diameter for example can be continuously or the mode that reduces gradually change, perhaps change in stepwise (stepwise) mode.In the situation of not wishing to be bound by theory, we think that the following embodiment of stability line 304 is favourable, that is, has larger diameter at near-end (namely towards handle portion 103), to reduce or to eliminate in the probability that applies flexing in the situation of higher load; Has less diameter towards far-end (namely near tip part 107) simultaneously, so that extra flexibility to be provided.In one embodiment, stability line 304 begins to have 0.020 inch diameter from near-end always, until be similar to 1 inch just variation by outer sheath 316.The diameter stepwise of the remainder of stability line 304 is changed to 0.016 inch.This embodiment can be used in the catheter shaft 302 of internal diameter for approximate 0.022-0.024 inch, so that the gap on each side is approximate 0.001-0.002 inch at near-end between catheter shaft 302 and the stability line 304, far-end is 0.003 inch.
With reference to figure 7, it shows the sectional view of handle portion 103.Fig. 8 shows the close up view of this sectional view.In a preferred embodiment, clamping part 202 is connected to stability line 304, although in some embodiments, stability line 304 also can be connected to plunger 204, perhaps alternatively is connected to plunger 204.Stability line 304 is disposed in the catheter shaft 302, and catheter shaft 302 preferably is configured to slide about stability line 304 in a longitudinal direction.
In certain embodiments, crimp tube 305 is used for stability line 304 is connected to clamping part 202.Crimp tube 305 is preferably by the metal construction harder than stability line 304, stainless steel alloy (for example SS304) for example, and form hypotube (hypotube).Preferably, crimp tube 305 is crimped onto the near-end of stability line 304, and the near-end of crimp tube 305 is maintained at clamping part 202 inside, and the far-end of crimp tube 305 is maintained in the remainder of main body of plunger 204.In some embodiments, crimp tube 305 can partly extend on the catheter shaft 302, for example extends 0.1 inch short length, because when power is applied to catheter shaft 302, this can be catheter shaft 302 extra anti-flexibility is provided.In some embodiments, crimp tube 305 can have approximate 0.039 inch internal diameter, 0.010 inch of wall thickness.
Catheter shaft 302 is connected to movably handle 206 through a skewer 216.Because movably handle 206 preferably is configured to slide along plunger 204 front and back, and because movably handle 206 is attached to catheter shaft 302, so movably the movement of handle 206 can cause catheter shaft 302 with respect to the corresponding movement of stability line 304.As discussed below, this moves the device that allows to be contained in distal tip 107 and ejects and expansion.In addition, locking lever 210 can be provided with a lock tab 222, and this lock tab 222 engages with recess 220 on the handle 206 movably, thereby helps to reduce or eliminate the probability that handle 206 movably slides along plunger 204.This set can be used for help reducing or eliminates unexpected or prematurely from conduit system 101 expanding units.In certain embodiments, catheter shaft 302 alternately is connected to plunger 204, and stability line 304 can be connected to movably handle 206 through described skewer 216.
Catheter shaft 302 preferably is fixed to handle portion 103, and in certain embodiments, one or more intermediate members can form the part of this connection.In some embodiments, refer now to Fig. 9 A-B, catheter shaft 302 can be fixed to the fork-shaped intermediate member, and for example skewer 216, and catheter shaft 302 for example can be clamped in the recess of fork-shaped intermediate member.Skewer 216 itself is connected to again movably handle 206.For clear, omitted movably handle 206, but movably handle 206 can be found out in Fig. 7-8 with the relation of miscellaneous part.
Skewer 216 preferably includes at least two prongs 217.These prongs 217 have an interval each other, and this interval is less than the diameter of catheter shaft 302.For catheter shaft 302 is connected to skewer 216, catheter shaft 302 (preferably being configured with circular cross section) can have one or more breach or the chamber 308 that forms thus thereon.Described breach or chamber 308 allow catheter shaft 302 is received in two intervals between the prong 217, this is because chamber 308 will cause catheter shaft 302 to have a segment distance of less cross section along the distance of catheter shaft 302, inserts and is fixed in two intervals between the skewer 217 to allow catheter shaft 302.Correspondingly, can form axial restraint between catheter shaft 302 and skewer 216 connects.Therefore because stability line 304 is positioned at catheter shaft 302, must be noted that breach or chamber 308,310 do not interfere in fact relatively moving freely of catheter shaft 304, or do not cut into catheter shaft 304.
Test demonstrates, and the skewer 216 (skewer 216 can by any suitable constructed of rigid materials, for example comprise stainless metal) by the rustless steel structure of an embodiment can bear the power greater than 20 pounds before losing efficacy.Therefore because user can not apply large like this power during launching, this structure is so that system 101 more may remain intact, and the inefficacy of skewer 216 unlikely causes catheter shaft 302 to separate with the remainder of system 101.
Again with reference to figure 1, also can outer sheath 316 be set in catheter shaft part 105.Outer sheath 316 can be between catheter shaft 302 and strain relief member 212, and can be used for (with strain relief member 212, if be provided with strain relief member 212) kinking of duct portion 105 and torsional load are minimized.For guaranteeing the reliable connection of sheath 316, preferably sheath 316 is fixed to plunger 204, for example by insert moulding (insert molding) or binding agent.In some embodiments, the outer sheath size between 22 to 39 inches, wall thickness between approximate 0.005-0.015 inch, preferably 0.010 inch.Preferably, outer sheath 316 has space or gap between itself and catheter shaft 302.In some embodiments, the size in this gap is between about 0.003-0.010 inch, and preferably each side is 0.005 inch.Be configured in the embodiment of aseptic (for example using the eo sterilization method) at some, the gap between catheter shaft 302 and the outer sheath 316 can be designed to allow fully flowing of antibacterial between two parts.
Outer sheath 316 is preferably by following material structure, comprises the polymer that for example forms with single polymer-extruded (single polymer extrusion), for example HDPE, PA-12, Polyurethane, the perhaps mixture of above material.In some embodiments, outer sheath 316 is formed by two kinds of different materials co-extrusions.Externally sheath 316 can use lubricious material towards a side of catheter shaft 302, for example HDPE, FEP, or other suitable material.In the outside of sheath 316, can use polymer--for example
Figure BDA0000120526840000102
Or PA-12 or other suitable material--obtaining the balance between following each factor, described factor such as can promote ability (for example limiting the amount of the power that user can apply), mechanical strength (for example non-deformability under load), bending resistance folding endurance, with friction and the manufacturability of tracheascope inside.In some embodiments, ray thoroughly material (for example barium sulfate) can be included into other elements of sheath 316 and/or conduit system 101.
With reference to figure 10A-C, can be along a series of cutting parts of all or part of formation of the cardinal principle of catheter shaft 302.These cutting parts can limit one or more flexible zones 330 that increase, and zone 330 usually can be than remaining uncut catheter shaft 302 better bending or warpage.In some embodiments, have been found that if the part of the far-end of catheter shaft 302 has the high flexibility zone 330 of cutting wherein, then conduit system 101 puts up a good show, and this is because the distal portions of catheter shaft 302 needs greatly bending, to pass through for example tortuous trachea path.The flexibility in high flexibility zone 330 can be designed according to the requirement of concrete application.For example change flexibility by interval, pitch (pitch) and angle between the cutting part in thickness, use therein material and the high flexibility zone 330 of revising catheter shaft 302.Preferably, cutting part extends in a spiral manner along catheter shaft 302.
In addition, high flexibility zone 330 needs not be the single pitch shown in Figure 10 A, but with reference to figure 10B, high flexibility zone 330 alternatively can be variable pitch, and wherein interval or pitch can change or the stepwise variation continuously.In addition, although can make continuous single cutting part at the cutting part shown in these figure, can use one or more discontinuous cutting parts to make the high flexibility zone.In these figure, the cutting part that consists of high flexibility zone 330 is made with " interlocking " configuration that forms sawtooth or zigzag pattern.Other feasible cutting parts are that following texts and pictures 16B and C illustrate and discuss " snake (serpentine) " configuration.In this snake configuration, cutting part is more smooth, round than indenting pattern, and has long amplitude.Other cutting part types are also feasible and can imagine, and comprise straight cuts section, part or dotted line cutting part, in a zigzag cutting part, sinusoid cutting part etc.
Figure 10 C shows an embodiment in the high flexibility zone 330 that comprises overlapping discontinuous straight cuts section, half extension of the approximate circumference around catheter shaft 302 of each cutting part.In this embodiment, punching 331 can be arranged on one or more ends of each cutting part.In some cases, punching 331 can be used as for generation of the part of the laser cutting parameter of cutting part and makes, but these cutting parts can use any suitable technique manufacturing, for example chemical etching.Punching 331 also can be used for guide tubular axis 302 provides extra intensity, and this is can help to reduce or eliminate the probability of cracks can spread when the different stress of catheter shaft 302 experience because believe punching 331.
In practice, high flexibility zone 330 and consist of that the processing of the cutting part in this high flexibility zone 330 can be such as expectation between the flexibility that requires and cutting part type, find appropriate balance.For example, although wider or larger cutting part can provide extra flexibility, these can weaken catheter shaft 302 to unacceptable degree in some cases.Different cutting part types also can more or less be worked in fatigue test satisfactorily.In addition, some cutting part can cause the service aisle of the part wearing and tearing tracheascope in high flexibility zone 330, but the post-treatment after cutting part produces can comprise for example deburring that can partly alleviate at least this misgivings or the step of ultrasonic waves for cleaning.Above-described cutting part type also can be adjusted according to the length in one or more high flexibilities zone 330.
In preferred embodiments, have been found that size can effectively work in 3 to 6 inches high flexibility zone 330 (pitch between the cutting part is between 0.010 to 0.100 inch).Having been found that in some embodiments, is gratifying in the scope of cutting part width (joint-cutting) between the 0.0015-0.0030 inch.
In certain embodiments,--for example polymer or heat-shrinkage material--covers high flexibility zone 330 at least can preferably to adopt the flexible protective layer.This protective layer can at least part of minimizing because the wearing and tearing of the service aisle inside of the tracheascope that cutting part causes, and also can reduce or eliminate the probability of catheter shaft 302 damages or excess elongation, this can help so that conduit can be used for repeatedly launching.In addition, this protective layer can also be smooth or lubricated, thereby allows catheter shaft 302 more easily to slide in the tracheascope service aisle.
Refer now to Figure 11 A-B and 12A-B, distal tip part 107 can be engaged to catheter shaft part 105 through connector 402.More specifically, in some embodiments, connector 402 is connected to distal tip part 107 with outer catheter axle 302.In preferred embodiments, distal tip part 107 can comprise cage cover 404, and this cage cover 404 is connected to catheter shaft 302 through connector 402.This cage cover 404 can by one or more enough durable material make, described material comprises metal, for example rustless steel and Nitinol.In some embodiments, cage cover 404 can be by preformed tubing structure, and some other embodiment can have the cage cover 404 by the flat structure of material, and described material is wound in longitudinal direction or the hand of spiral subsequently and forms pipe.
Distal tip part 107 preferably is configured to comprise chamber 405 in the inner, position, and the size in chamber 405 is configured to receive suitable device subsequently to be unfolded.Preferably, cage cover 404 comprises and is positioned at the chamber 405 that cage overlaps 404 inner spaces.
In some embodiments, illustrate such as Figure 11 B and 12B, chamber 405 can hold medical treatment device, and for example valve 500.In some cases, use in US serial number 12/249,243 and 12/422, the valve loader of type described in 179 can be loaded into chamber 405 with valve 500 by distal openings 410, described US serial number 12/249,243 and 12/422,179 includes in full this paper in separately at this.In case be loaded into chamber 405, the proximal end in abutment of device (for example valve 500) is against propeller plunger 408, propeller plunger 408 then be connected to stability line 304.In use, movably handle 206 moves about the near-end of plunger 204 in handle portion 103, causes cage cover 404 to be retracted with respect to propeller plunger 408, thereby discharges the device (for example valve 500) that is contained in the chamber 405 from opening 410.
Fenestra 409 is preferably located at least a portion of cage cover 404, and the flexibility that can be used for improving the visuality that is positioned at device wherein and improve distal tip part 107.Remaining stay 411 forms cage cover or tower structure, and can comprise spiral or interlaced helical pattern, and however different configurations and pattern also are feasible.Fenestra 409 for example can be by cut.Also can utilize other method, for example photochemistry milling.
Preferably, cage cover 404 also comprises one or more large fenestras 413.This large fenestra 413 is conducive to observe the device that is positioned at chamber 405, and confirms that device suitably or correctly is loaded in the chamber 405.Large fenestra 413 also can be used for providing one for the clear area of telltale mark band or other telltale mark (hereinafter discussing in detail).Preferably, whole cage cover 404 is constructed by single piece of material, and comprises that the distal portions of the cage cover 404 at edge 415 can be connected to through vertical stay 414 proximal part of cage cover 404.
In the manufacturing of distal tip part 107, advantageously coated distal end tip part 107 and cage overlap 404 interior section and/or exterior section.For example, apply softer material (for example polymer) and can effectively avoid when using conduit systemic injury, and help distal tip part 107 in the service aisle of tracheascope or Other Instruments, freely to slide.In addition, the interior section that applies conduit can help to reduce or eliminate being loaded in the destruction of medical treatment device wherein, perhaps reduces or eliminate the probability of obstruction medical treatment device expansion.
Therefore, some embodiment provides lining at least a portion of the inner surface that is positioned at cage cover 404 or chamber 405 (--for example politef--forms for example by polymer), in conjunction with the lining on the outer surface that is positioned at least distal tip 107 parts (can be by polymer--for example
Figure BDA0000120526840000131
--form).
In some embodiments, but these coating or lining soft heat (reflowed) to distal tip part 107.Use axle, can apply heat with these lining soft heats on the metal part of far-end 302.Preferably, selected lining is about fenestra 409,413 at least part of transparent, so that can check loading medical treatment device wherein.Different piece along distal tip 107, can use different polymer and polymer type, wherein for example only use transparent polymer along a part of distal tip 107, and use opaque or coloured polymer along a different piece of distal tip 107, to allow that conduit is processed into application and the purposes of expection specially.As hereinafter with among Figure 15 discussing, these polymer coatings and soft heat also can be incorporated in telltale mark on the distal tip part 107 or in the distal tip part 107.Useful diverse ways makes distal tip part 107 coating, comprises immersion coating, pushes, applies heat-shrinkage material etc.
In a preferred embodiment, be configured to around the edge 415 of opening 410 that is positioned at distal tip part 107 far-ends smooth and atraumatic, to reduce or to eliminate when inserting and launching to be arranged in the device in chamber 405 probability to systemic damage.
Preferably, with reference to Figure 13, edge 415 comprises a series of little weld part (welds) around opening 410 circumferential arrangement, and described weld part for example can adopt laser weld to make, so that smooth, rounded ends to be provided.In this case, edge 415 can be configured to provide atraumatic tip thus, and this tip is so that minimum to obstruction or other clampings of 405 devices that launch from the chamber, simultaneously also so that it is durable and can support multiple use.In other embodiments, edge 415 can be aggregated thing or the covering of other soft material layer.
Now again with reference to figure 11A-B and 12A-B, in some embodiments, via the far-end of cage cover 404 or catheter shaft 302, connector 402 can be along the border that connector 402 is engaged to distal tip part 107 by roll welding (seam-welded).This welding is preferred, because it provides the more smooth transition from catheter shaft part 105 to distal tip part 107, has reduced thus operator's operation easier, and helps to provide the movement of the smooth and continuous of system 101 during launching.Also can use spot welding, but should note reducing the size of spot welding, prevent from excessively giving prominence to, this is because the danger that exists this weld part to block in tracheascope or hinder.
With reference to Figure 14, some embodiment provides the connector 402 by the multi-part design structure.In these embodiments, compression circular cone 430 for example is attached to the far-end of outer conduit axle 302 by welding.Lasso (ferrule) 432 is for example by welding or being attached to far-end 402 by mechanical interlocking simply, and lasso 432 can be pushed subsequently crosses compression circular cone 430, is clipped in the middle with the near-end with cage cover 404.This interlocking connects and comprises connector 402, and forms the strong connection that can resist most pulling force.Specimen can be born at least pulling force of 100N.
Now forward Figure 15 to, an embodiment of system 101 can be provided with telltale mark.These telltale marks for example can be arranged on the part of far-end of distal tip part 107 and catheter shaft part 105.Usually, telltale mark helps the operator to determine that system 101 is about the position of external object.Telltale mark can be visual, is useful at the visibility constrained environment in--field of view scope of for example seeing by tracheascope--therefore.More specifically, telltale mark can help to select and indicate suitable expansion position for the medical treatment device that is loaded in the conduit, and is used for allowing the operator to determine that whether conduit extends too far away from service aisle or other conveyer device of tracheascope.
Some embodiment can be provided with one or more telltale marks, and line 445,446,447 for example, these telltale marks can help to select and indicate suitable expansion position for the medical treatment device that is loaded in the conduit.Herein, when the conduit that accommodates device is loaded into tracheascope, and when being directed to the part (for example lung qi pipe) of the health that requires treatment, the operator can use line 445 position that conduit and medical treatment device is to be unfolded to aim at, because the apparent position that line 445 can indicate medical treatment device to discharge from opening 410.In some embodiments, device can be the valve 500 that launches in trachea, and in these cases, line 445 films common and valve 500 will seal the air flue regional alignment that props up.These embodiments hereinafter and Figure 20 A-C describe in further detail.
Line 445 can be particularly advantageous in and help to observe passage by tracheascope and see suitable expansion position, and some embodiments so that line 445 by other black or have different contrasts color belts 446,447 around or be clipped in the middle, so that extra contrast to be provided.--for example bat printing or ink jet printing--is marked at distal tip part 107 with line 445, considers biocompatibility although can adopt suitable means, sometimes must make line 445 not adopt the pigment of exposure in its structure.In these cases, some embodiments can be used the indicia band of arranging around distal tip part 107.These indicia band can be comprised of polymer belt, for example by heat-shrinkable polymer--and for example
Figure BDA0000120526840000151
--structure.Owing to have been found that yellow line 445 is favourable in some applications, therefore golden indicia band can be enclosed within on the distal tip part 107.Indicia band can be made of any suitable material, and preferably the material by highly-visible consists of.Have been found that the gold that for example is mixed with iridium or the material of platinum are acceptable materials.Optionally, can be encapsulated in the lining below of describing in above the softening-melting process as the indicia band of line 445, perhaps be encapsulated in one other and preferably at least part of transparent polymer is (for example
Figure BDA0000120526840000152
) layer below.
In some embodiments, can be by a row or a series of fenestra be cut into distal tip part 107 formation line 445 or other telltale marks, so that do not need extra material to form corresponding telltale mark.In addition, although above-described line 445 is positioned on the distal tip part 107, other embodiments can place line 445 other parts of system 101.For example, line 445 can on stability line 304 or plunger 408, wherein if necessary, can advance with the cutting that is associated aperture or the fenestra of distal tip part 107, to allow to see line 445.
In addition, some embodiment can arrange long telltale mark 448, for example is positioned at the distal portions of catheter shaft 105.This long telltale mark 448 can be used the cautionary characteristic of doing the operator, and it is too far away that warning conduit system 101 has extended through tracheascope.This long telltale mark 448 is preferably painted or coloured, for example be contrast color (for example yellow), with easily when conduit will extend through tracheascope the person of being operated see.Can use any suitable means (describe before comprising be used for line 445,446,447 means) that long telltale mark 448 is placed catheter shaft 105.Preferably, long telltale mark 448 can be by suitable thermal contraction polymer architecture, and in some cases, this polymer can be covered by pure or colourless protection polymeric layer subsequently.In some embodiments, the size of long telltale mark 448 can be preferably 6 inches between 5 to 10 inches, and can be positioned at apart from approximate 2 inchs of distal tip.
Although telltale mark discussed above mainly refers to visual indicant, the telltale mark that uses in the system 101 also can be configured to use other means location.For example, any telltale mark or line 445,446,447,448 can be constructed by radiopaque material (for example barium sulfate), or include radiopaque material (for example barium sulfate), in order to locate with the radial imaging method.In the embodiment of the MRI of system 101 compatibility, the MRI contrast medium also can be incorporated into telltale mark.Active (being provided power) or passive (for example passive RFID) witness marker lamp (beacon) also can be incorporated into distal tip part 107, described witness marker lamp can together work with above-mentioned telltale mark, or alternative telltale mark discussed above works, and described telltale mark lamp can work together with mapping software, with the position of real-time tracing distal tip part 107, and do not need requirement visual confirmation distal tip part 107 with respect to the position of launching the position.These telltale marks are also in conjunction with the mixed positioning labelling of multiple localization method, for example not only ray not thoroughly, but also visual telltale mark.
Figure 16 A-H shows the different embodiments of distal tip part 107.Although these designs have some similar with Figure 11 A-B and 12A-B, at this extra difference and feature will be discussed.At first forward Figure 16 A to, an embodiment of distal tip part 107 is shown, it comprises coiled arrangement staggered in the cage cover 404 (with continuous spiral or the helix configuration contrast among Figure 11 A-B).The extra material that stay 411 is linked together can provide additional intensity, resists external force and the internal forces (for example twisting resistance or bending force) that can be applied in use tip.In a preferred embodiment, cage cover 404 can by Nitinol sheet material structure, by chemical etching, and be rolled onto cylindrical.
In addition, connector 402 is provided with one at this and is similar to the multi-part connector that Figure 14 discusses.Also can present the telltale mark that comprises line 445.As previously discussed, this embodiment comprises on the catheter shaft 302 the high flexibility zone 330 with the cutting part configuration of interlocking.
Figure 16 B shows on catheter shaft 302 the similar embodiment with different high flexibility zones 330, and current high flexibility zone 330 is with the snake design forming.
Now go to Figure 16 C, this embodiment comprises the high flexibility zone 450 that is integrated on the distal tip part 107, and 450 other aspects, this high flexibility zone are similar to the high flexibility zone 330 shown in Figure 16 A, except herein zone 450 is on distal tip part 107.This sentences the high flexibility zone 450 that snake cutting part configuration makes and is connected to catheter shaft part 105 through connector 402, and is connected to cage cover 404 via the second connector 430.In addition, except the high flexibility zone 450 that illustrates herein, some application may need guide tubular axis 302 to increase another extra high flexibility zone 330 of describing type before.In some cases, can be in the high flexibility zone and/or the inside in cage cover zone be provided with the lining of PTFE or other smooth polymer minimum so that stability line extends through the flexing of finished product conduit.
Figure 16 D shows another embodiment of the distal tip part 107 that is similar to the embodiment of describing in Figure 16 C.Herein, high flexibility zone 450 comprises indenting design.
Figure 16 E shows an embodiment that is similar in the distal tip part 107 of the embodiment shown in Figure 11 A, and wherein cage cover 404 comprises coiled arrangement.Herein, be positioned at high flexibility zone 330 on the catheter shaft 302 and comprise overlapping discontinuous straight cuts section, each cutting part is around approximate half circumferential extension of catheter shaft 302.These cutting parts can be similar in the configuration shown in Figure 10 C.Because these cutting parts are discontinuous, other high flexibility area types shown in this paper that therefore cause comparing, some embodiments in this high flexibility zone 330 can have extra intensity.
Figure 16 F shows an embodiment of the distal tip part 107 that comprises tapering part.Herein, cage cover 404 is connected to tapering part 452 through the second connector 403, and the diameter of this tapering part 452 diminishes gradually towards its near-end.Tapering part 452 is connected to catheter shaft 302 through connector 402, and can be provided with the high flexibility zone 330 that is similar to the preamble description.In some embodiments, tapering part and/or cage cover can form in the following way, that is, use is made the spiral packaging thing through the sheet stock of the rigid material (for example Nitinol) of photochemical etching and is formed (however also can adopt different metals or material).Some advantages of this taper embodiment can comprise that the conduit system 101 more level and smooth tracheascope service aisles that move through move.
Figure 16 G shows another embodiment of the distal tip part 107 that comprises a different tapering part.Herein, cage cover 404 itself forms individual unit (with Figure 16 E contrast), and diminishes gradually towards its near-end size.In some cases, many designs of Figure 16 E that compares, the manufacturing of this cage Analysis of Nested Design of Figure 16 G and assembling are more cheap, and in some cases can be by single Nitinol sheet material through photochemical etching, and subsequently rolling is shaped.This single-piece taper embodiment can also be made like this, so that the staggered coiled arrangement that illustrates is not extended closely as illustrating herein, so that can being similar to the embodiment shown in Figure 16 F, this embodiment do not have the second connector 403 herein.Preferably, cage cover 404 uses connector 402 types of describing among above-mentioned Figure 14 to be attached to catheter shaft part 105.As Figure 16 F, high flexibility zone 330 (being " interlocking " type) can be presented on the catheter shaft 302 herein.
Figure 16 H shows a different configuration of the cage cover 404 that can use in some embodiment of distal tip part 107.Herein, cage cover 404 is not spiral or helix configuration, but forms with the configuration that interweaves that illustrates.The preferred cut of this configuration forms, but different manufacture methods (for example photochemistry milling) also is feasible.This embodiment of cage cover 404 to be configured in the application that distal tip part 107 requires extra flexibility be favourable.In some configurations, for example when cage cover 404 construct by Nitinol, can use the Nitinol compression ring that cage is overlapped 404 and be fixed to catheter shaft part 105, rather than the connector type shown in connector 402 or Figure 14.
