Definitions
- the present invention relates to methods and apparatuses for securing elongated medical devices such as catheters or leads within a cranial burr hole.
- Deep brain stimulation (DBS) and other related procedures involving implantation of leads and catheters are increasingly used to treat Parkinson's disease, dystonia, essential tremor, seizure disorders, obesity, depression, restoration of motor control, and other debilitating diseases.
- a catheter, lead, or other medical device is strategically placed at a target site in the brain. The body of the device then exits through a burr hole cut in the skull. The device must be secured as it exits the skull so as to prevent movement of the device from the precise target site in the brain, and the burr hole must be filled.
- burr hole plugs Due to a lack of adequate burr hole plugs, many physicians attempt to compensate by securing the device to the skull with sutures and clamping screws, and then filling the burr hole with cyanoacrylate or bone cement. Securing the device with sutures and clamping screws subjects the patient to unnecessary human error. Further, suturing and clamping are cumbersome and time consuming steps. Filling the burr hole with cyanoacrylate or bone cement is messy and permanently locks the device into place, preventing easy access for future necessary procedures.
- the present invention addresses the above and other needs by providing a burr hole plug, a method of implanting the burr hole plug, and an insertion tool.
- the burr hole plug includes a shell, a collet, a clamp, and a cover.
- the burr hole plug is smaller than most currently available burr hole plugs.
- the burr hole plug is installed and secures the exiting device with simultaneous 360° radial pressure from the collet portion of the burr hole plug, thus avoiding disturbance of the position of a medical device at the target site in the brain.
- the clamp mechanically locks the collet around the body of the medical device without exposing the medical device to pulling, pushing, or twisting forces that could cause unwanted displacement of the medical device from its target site in the brain.
- the collet simply clamps the medical device from all directions through radial force.
- the collet including all other parts of the burr hole plug, is capable of being mechanically unlocked and disassembled to release the medical device and perform any needed future procedures.
- the device is able to exit the brain at a gradual angle through a conical chamber within the collet, through the tip of the conical chamber where the collet grips the device, and out from underneath the protective cover placed over the collet and clamp.
- the method of implantation includes inserting the shell that is sized to friction fit against the inner circumference of the burr hole; interlocking a collet within the shell; placing a clamp over the collet, which clamp compresses the collet as the clamp rotates and interlocks with the shell; and placing a cover over the clamp, collet, and shell. Certain portions of the burr hole plug may be inserted separately or simultaneously using an insertion tool tailored to maximize the efficiency of implantation.

Abstract
A cranial burr hole plug with an insertion tool and method of implantation is provided. The burr hole plug includes a shell; a collet interlocked within the shell; a clamp compressing the collet around an elongated medical device exiting the skull of a patient, such as a catheter or lead; and a cover over the clamp, collet, and shell. The insertion tool inserts the collet within the shell and locks the collet around the clamp. The method of implantation includes inserting the burr hole plug components in a cranial burr hole using the insertion tool and securing the exiting medical device without disturbing the position of the medical device.
Description
- The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/403,787, filed Aug. 14, 2002, which application is incorporated herein by reference in its entirety.
- The present invention relates to methods and apparatuses for securing elongated medical devices such as catheters or leads within a cranial burr hole.
- Deep brain stimulation (DBS) and other related procedures involving implantation of leads and catheters are increasingly used to treat Parkinson's disease, dystonia, essential tremor, seizure disorders, obesity, depression, restoration of motor control, and other debilitating diseases. During these procedures, a catheter, lead, or other medical device is strategically placed at a target site in the brain. The body of the device then exits through a burr hole cut in the skull. The device must be secured as it exits the skull so as to prevent movement of the device from the precise target site in the brain, and the burr hole must be filled.
- Current burr hole plugs placed under the skin of a patient's head are unduly large and unsightly. Further, many current burr hole plugs do not adequately hold the exiting device in place; some force the device to bend at a right angle at the exit without any protection which makes the device vulnerable to fracture or short circuit. During placement of current burr hole plugs, the exiting device often moves from its precise target site in the brain. After placement of current burr hole plugs, the device may migrate over time and will require additional surgical procedures to correct the problem.
- Due to a lack of adequate burr hole plugs, many physicians attempt to compensate by securing the device to the skull with sutures and clamping screws, and then filling the burr hole with cyanoacrylate or bone cement. Securing the device with sutures and clamping screws subjects the patient to unnecessary human error. Further, suturing and clamping are cumbersome and time consuming steps. Filling the burr hole with cyanoacrylate or bone cement is messy and permanently locks the device into place, preventing easy access for future necessary procedures.
- There is, therefore, a need to provide a relatively small burr hole plug that, without disturbing the position of the device at the target site in the brain, adequately and permanently secures a medical device such as a catheter or lead exiting a burr hole at a gradual angle, but remains accessible for future procedure. Further, there is a need to provide a method of implanting a burr hole plug that mitigates human error and permits safe and efficient implantation.
- The present invention addresses the above and other needs by providing a burr hole plug, a method of implanting the burr hole plug, and an insertion tool. The burr hole plug includes a shell, a collet, a clamp, and a cover. The burr hole plug is smaller than most currently available burr hole plugs. The burr hole plug is installed and secures the exiting device with simultaneous 360° radial pressure from the collet portion of the burr hole plug, thus avoiding disturbance of the position of a medical device at the target site in the brain. The clamp mechanically locks the collet around the body of the medical device without exposing the medical device to pulling, pushing, or twisting forces that could cause unwanted displacement of the medical device from its target site in the brain. The collet simply clamps the medical device from all directions through radial force. The collet, including all other parts of the burr hole plug, is capable of being mechanically unlocked and disassembled to release the medical device and perform any needed future procedures. The device is able to exit the brain at a gradual angle through a conical chamber within the collet, through the tip of the conical chamber where the collet grips the device, and out from underneath the protective cover placed over the collet and clamp.
- The method of implantation includes inserting the shell that is sized to friction fit against the inner circumference of the burr hole; interlocking a collet within the shell; placing a clamp over the collet, which clamp compresses the collet as the clamp rotates and interlocks with the shell; and placing a cover over the clamp, collet, and shell. Certain portions of the burr hole plug may be inserted separately or simultaneously using an insertion tool tailored to maximize the efficiency of implantation.
- This summary should not be taken in a limiting sense; the scope of the invention should be determined with reference to the claims.
- The above and other aspects of the present invention will be more apparent from the following more particular description thereof, presented in conjunction with the following drawings wherein:

- The following description includes the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of the invention. The scope of the invention should be determined with reference to the claims.
- The present invention is a burr hole plug, an insertion tool, and a method for implanting the burr hole plug.
- As shown in
FIG. 1 , the burr hole plug has four main components: ashell 100, acollet 200, aclamp 300, and acover 400. The burr hole plug, and its components, can be modified to match any shape or size of burr hole in the skull. -
FIG. 2 shows an alternate embodiment of the burr hole plug with four alternate main components: ashell 100′, acollet 200′, aclamp 300′, and acover 400′.Shell 100′ and cover 400′ and their various alternate embodiments may be used withcollet 200 andclamp 300 ofFIG. 1 and their various alternate embodiments to form a number of alternate burr hole plug combinations. Similarly,shell 100 andcover 400 ofFIG. 1 and their various alternate embodiments may be used withcollet 200′ andclamp 300′ and their various embodiments to form a number of alternate burr hole plug combinations. - As shown in

An alternate embodiment ofshell 100 has a side slot along the full length ofshell 100. This permits the alternate embodiment ofshell 100 to be inserted into a burr hole after a medical device is inserted into the brain by sliding the body of the medical device through the side slot as thealternate shell 100 is moved into place. -
Flange 110 preventsshell 100 from being inserted deeper than the exterior surface of the skull.Flange 110 has amedical device exit 111 that secures the medical device and permits the medical device to gracefully exit the burr hole plug. Alternate embodiments of a medical device exit may include a similar structure such as a channel, hole, bump, tunnel, tube, or gate that secures the medical device and permits the medical device to exit. -
Shell 100 is either anchored to the skull, anchored to the skull and cover 400 ofFIG. 1 , or anchored to cover 400 ofFIG. 1 . Illustrative embodiments that enable anchoring follow.

At least twopins 940permit insertion tool 900 to engage with at least twoholes 340 and lockclamp 300 or clamp 300′ into place by rotatinginsertion tool 900 and clamp 300 or clamp 300′ simultaneously.Ribs 930 and pins 940 are either on opposite ends of thesame insertion tool 900 or are on separate tools. The body ofinsertion tool 900 need not be cylindrical, but can be take any size, shape, or form as long as it is constructed of a hard material such as stainless steel and has structures such asribs 930 orpins 940 that are compatible with and capable of being engaged withcollet 200,collet 200′,clamp 300, or clamp 300′. - A method for implanting a burr hole plug includes a combination of the following steps in various orders so that the burr hole plug securely fastens and protects a medical device exiting the skull. Except when necessary, only the structures of the burr hole plug of
FIG. 1 are described in the following method. However, this method also applies to the structures of the burr hole plug ofFIG. 2 and all other embodiments of the present invention. - A burr hole is created.
Shell 100, which is shaped and sized to form a dimensionally close press fit with the internal circumference or surface of the burr hole, is positioned and inserted by being pressed into the hole. If desired,shell 100 is fixed or anchored to the skull by small screws or other anchoring structures. The target site of the medical device in the brain is located, and the medical device is placed in the brain. To close the burr hole plug,collet 200 is carefully inserted into the opening ofshell 100 and properly rotated usinginsertion tool 900 to an interlocking position withshell 100.Clamp 300 is then carefully placed inshell 100 oncollet 200 such that pins 330 align with interlockingslots 120 and clamp 300 is pressed and rotated usinginsertion tool 900 to an interlocking position withshell 100. Compression and rotation ofclamp 300lock clamp 300 intoshell 100 and restrain the medical device from further movement in the burr hole. - During the process of closing the burr hole plug, the medical device is not exposed to pulling, pushing, or twisting forces that could cause an unwanted displacement of the medical device from its target site in the brain. The medical device is simply clamped from all directions through radial force from the collet.
Plug cover 400 is placed on the top of the burr hole and attached securely by sliding undercut 410 undershell flange 110, employing at least one anchoring arrangement described above. - Alternately, plug
cover 400′ is anchored to shell 100′ and/or the skull using at least one anchoring arrangement described above. Cover 400 or cover 400′ protects the medical device at the exit and prevents the medical device from fracturing. - As shown in
FIG. 11 ,shell 100 andcollet 200, or their corresponding alternate embodiments, are integrated either permanently, such as by a weld or combined mold, or temporarily, such as by adhesive with a weak bond, to form a shell-collet 500. Integrated shell-collet 500 reduces the number of components for installation thereby reducing the number of steps needed in the insertion and closing procedure. The procedure of inserting a burr hole plug with an integrated shell-collet 500 is essentially the same as the procedure of inserting a burr hole plug with aseparate shell 100 andcollet 200 except that shell-collet 500 is inserted into the burr hole after the medical device is inserted into the brain. Integrated shell-collet 500 may have a side slot along its full length in order to permit shell-collet 500 to mount and encircle a medical device at any point along the medical device's length. - As shown in
FIG. 12 ,collet 200′ and clamp 300′ may be temporarily combined or integrated as by a weakadhesive bond 610 to form collet-clamp 600. Integrated collet-clamp 600 reduces the number of components individually inserted byinsertion tool 900 and thus reduces the number of steps needed during a burr hole closing procedure. Wheninsertion tool 900 places collet-clamp 600 intoshell 100, lockingbase 260 of the collet portion of collet-clamp 600 is interlocked with lockingbase 130 ofshell 100, insertion tool and the clamp portion of collet-clamp 600 are rotated, and weakadhesive bond 610 between the collet and clamp portions is broken. Whenbond 610 is broken,individual collet 200′ remains in a locked position inshell 100′ orshell 100 and clamp 300′ is then rotatably locked againstshell 100′ orshell 100 by engagingpins 330 ofclamp 300′ with interlocking slots ofshell 100′ or interlockingslots 120 ofshell 100. Similar weak adhesive, cohesive, magnetized, or other bonds placed prior to procedure may combine various components of the burr hole plug, i.e., shell 100′,collet 200′, clamp 300′, or cover 400′, with insertion tools for ease of use and implantation. After the components are placed in locked position, the bond will easily break, allowing an insertion tool to be removed. - While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
