Implant system
A system and method for inserting an implant into soft tissue. The system may include an elongate arm having an implant at a first end of the elongate arm and an actuator at a second end of the elongate arm. The implants may be contained in a cartridge assembly. Methods of inserting an implant may be used during nasal septum reconstruction.
1. An implant system for approximating tissue comprising:
a first flexible ribbon comprising a tip configured to engage an implant;
a second flexible ribbon abutting the first flexible ribbon and comprising a tip configured to penetrate tissue;
a handle;
a first elongate arm extending from the handle, the first elongate arm having a first end which is configured to receive an implant and a second end coupled to the handle, the first end of the first elongate arm having a channel for receiving and guiding the first and second flexible ribbons;
a second elongate arm extending from the handle, the second elongate arm having a first end opposed to the first end of the first elongate arm and a second end coupled to the handle; and
an actuator for actuating the first and second flexible ribbons to deploy the tips of the first and second flexible ribbons out of the first end of the first elongate arm, wherein the actuator comprises a trigger.
2. The implant system of claim 1 , wherein the actuator is configured to be placed into a first position where the second flexible ribbon extends to penetrate tissue located between the first ends of the first and second elongate arms to create a hole in the tissue and a second position where the first flexible ribbon extends to deploy an implant in the hole created by the second flexible ribbon.
3. The implant system of claim 1 , wherein the second flexible ribbon is longer than the first flexible ribbon so that the tip of the second flexible ribbon extends past an implant engaged by the first flexible ribbon.
4. The implant system of claim 1 , wherein the first and second ribbons comprise a superelastic material, and wherein the first and second flexible ribbons are in contact with each other and are configured to be moved together by the actuator.
5. The implant system of claim 1 , further comprising first and second actuator rods for coupling the actuator to the first and second flexible ribbons, respectively.
6. The implant system of claim 1 , further comprising a cartridge assembly coupled to and proximal the first end of the first elongate arm, the cartridge assembly comprising a plurality of implants.
7. The implant system of claim 1 , wherein the first ends of the first and second elongate arms are spaced apart from one another and configured to receive a nasal septum between the first ends.
8. The implant system of claim 1 , wherein the first ends of the first and second elongate arms are configured to move towards one another prior to actuation of the first and second flexible ribbons.
9. An implant system for approximating tissue comprising:
a handle;
a first elongate arm extending from the handle, the first elongate arm having a first end which is configured to receive an implant and a second end coupled to the handle; and
a second elongate arm extending from the handle, the second elongate arm having a first end and a second end coupled to the handle, wherein the first and second elongate arms are in contact with the handle;
a first flexible ribbon proximal to the first end of the first elongate arm, wherein the first flexible ribbon is configured to engage the implant; and
a second flexible ribbon abutting the first flexible ribbon and proximal to the first end of the first elongate arm, wherein the second flexible ribbon comprises a first tip configured to penetrate tissue.
10. The implant system of claim 9 , further comprising an actuator for actuating the first and second flexible ribbons.
11. The implant system of claim 10 , further comprising first and second actuator rods for coupling the actuator to the first and second flexible ribbons, respectively.
12. The implant system of claim 10 , further comprising a guide proximal to the first end of the first arm for guiding the first and second flexible ribbons, wherein the first and second flexible ribbons are actuated together such that both the first and second flexible ribbons move relative to an actuator.
13. The implant system of claim 9 , further comprising a cartridge assembly coupled to and proximal the first end of the first elongate arm, the cartridge assembly comprising a plurality of implants.
14. The implant system of claim 9 , wherein the first ends of the first and second elongate arms are spaced apart from one another and configured to receive a nasal septum between the first ends.
15. The implant system of claim 14 , wherein the first ends of the first and second elongate arms are configured to move towards one another prior to actuation of the first and second flexible ribbons.
16. The implant system of claim 9 , further comprising a channel in the first end of the first arm for guiding the implant.
17. A method of approximating tissue comprising:
providing an implant system comprising
a handle;
a first elongate arm extending from the handle, the first elongate arm having a first end which is configured to receive an implant and a second end coupled to the handle; and
a second elongate arm extending from the handle, the second elongate arm having a first end and a second end coupled to the handle, wherein the first and second elongate arms are in contact with the handle;
a first flexible ribbon proximal to the first end of the first elongate arm, wherein the first flexible ribbon is configured to engage the implant; and
a second flexible ribbon abutting the first flexible ribbon and proximal to the first end of the first elongate arm, wherein the second flexible ribbon comprises a first tip configured to penetrate tissue;
placing the first end of the first elongate arm adjacent tissue to be approximated;
actuating the second flexible ribbon to penetrate the tissue to create a hole in the tissue; and
actuating the first flexible ribbon to push the implant through the hole in the tissue.
18. The method of claim 17 , further comprising:
inserting the first end of the first elongate arm in a first nasal cavity;
inserting the first end of the second elongate arm in a second nasal cavity; and
positioning the first ends of the first and second arms at a target location.
19. The method of claim 17 , further comprising moving the first and second ends of the first elongate arm and the second elongate arm toward one another so that the second elongate arm provides backing support to the tissue into which the implant will be inserted.
20. The method of claim 17 , further comprising withdrawing the second flexible ribbon from the hole in the tissue, wherein the first and second flexible ribbons each have a rectangular cross-section with respect to a longitudinal axis thereof.
