Abstract

An implant delivery system is described. The implant delivery system utilizes an implant, implant wire, delivery sheath, and a torque device. The torque device may include a cutting element to slit the delivery sheath and a clamp device to fix the position of the implant delivery wire.

First claim

What is claimed is:

1. An implant delivery device for delivering a medical implant operatively connected to an elongated implant wire, comprising:
a torque device comprising:
a body member including a first recessed area;
a removable mating piece including a second recessed area, wherein the first recessed area of the body member is aligned with the second recessed area of the removable mating piece to form a first passage extending through the body member;
a separator member removably located within the first passage and allowing passage of the elongated implant wire; the separator member comprising a separator tube and a cutting element that is fixed to the separator tube and positioned proximally of a distal end of the separator tube;
a second passage connecting to the first passage near the cutting element, the second passage extending away from the first passage; and
wherein the cutting element is positioned in the first passage in between the body member and the removable mating piece to slit a sheath passing through the first passage and wherein the torque device directs the slit sheath out of the first passage while leaving the medical implant in place.

2. The implant delivery device of claim 1 , wherein the second passage is comprised of the first and second recessed areas of the body member and a recessed area in the removable mating piece that mate with each other.

3. The implant delivery device of claim 1 , further comprising a clamp mechanism which selectively presses against the elongated implant wire.

4. The implant delivery device of claim 3 , wherein the clamp mechanism comprises a collet and a screw member that is selectively contactable with said collet, so as to increase or decrease a diameter of the collet.

5. The implant delivery device of claim 1 , wherein the body member and the removable mating piece both have apertures which align to facilitate connection between the body member and the removable mating piece.

6. The implant delivery device of claim 1 , wherein the torque device directs the sheath into the second passage.

7. An implant delivery device for delivering a medical implant operatively connected to an elongated implant wire, comprising:
a torque device comprising:
a body member including a first recessed area;
a mating piece that removably connects to and mates with the body member, the mating piece including a second recessed area, wherein the first recessed area of the body member is aligned with the second recessed area of the mating piece to form a first passage extending through the body member;
a separator tube removably located within the first passage and allowing passage of the elongated implant wire;
a cutting element that is fixed adjacent to the separator tube and positioned proximally of a distal end of the separator tube; the cutting element being removably located from the first passage;
a second passage connecting to the first passage near the cutting element, the second passage extending away from the first passage; and
wherein the cutting element is positioned in the first passage in between the body member and the mating piece to slit a sheath passing through the first passage and wherein the torque device directs the slit sheath out of the first passage while leaving the medical implant in place.

8. The implant delivery device of claim 7 , wherein the second passage is comprised of the first recessed area and the second recessed area that mate with each other.

9. The implant delivery device of claim 7 , further comprising a clamp mechanism which selectively presses against the elongated implant wire.

10. The implant delivery device of claim 7 , wherein the cutting element is disposed underneath the first passage, opposite of the second passage.

11. The implant delivery device of claim 7 , wherein the cutting element is disposed above the first passage, adjacent to the second passage.

12. The implant delivery device of claim 7 , wherein the body member and the mating piece both have apertures which align to facilitate connection between the body member and the mating piece.

13. The implant delivery device of claim 7 , wherein the torque device directs the sheath into the second passage.

14. An implant delivery device for delivering a medical implant operatively connected to an elongated implant wire, comprising:
a torque device comprising:
a body member including a first recessed area;
a mating means for removably connecting to and mating with the body member, the mating means including a second recessed area, wherein the first recessed area of the body member is aligned with the second recessed area of the mating means to form a first passage when the mating means is connected to the body member;
a separator means for slitting a sheath passing through the first passage, the separator means being removably located within the first passage and allowing passage of the elongated implant wire; and
a second passage is connected to the first passage near the separator means, the second passage extending away from the first passage.

15. The implant delivery device of claim 14 , wherein the separator means is comprised of a separator tube and a cutting element that is fixed to the separator tube and positioned proximally of a distal end of the separator tube.

16. The implant delivery device of claim 14 , wherein the second passage is comprised of the first recessed area and the second recessed area that mate with each other.

17. The implant delivery device of claim 14 , further comprising a clamping means for selectively pressing against the elongated implant wire.

18. The implant delivery device of claim 14 , wherein the torque device directs the sheath into the second passage.

19. The implant delivery device of claim 14 , wherein the body member and the mating means both have apertures which align to facilitate connection between the body member and the mating means.

20. The implant delivery device of claim 15 , wherein the cutting element is disposed underneath the first passage.
