Abstract

A punching device, for punching a lumen and implanting an implant device, includes at least the implant device for punching the lumen and for implantation into the lumen. In addition, the punching device includes an implantation device, a closure device, and an actuation device.

First claim

The invention claimed is:

1. A method for implanting an implant device, comprising:
bringing about an opened state of a closure device to release a restoring force by at least one actuation of an actuation device coupled to the closure device, the closure device being coupled to an implantation device;
punching a lumen by the implant device coupled to the implantation device by effectuating a forward motion of the implantation device;
executing a return motion of the implantation device by at least one actuation of the actuation device; and
implanting the implant device into the lumen after punching the lumen;
wherein punching the lumen comprises punching a hole in the lumen with a cutting edge of the implant device.

2. The method of claim 1 , wherein implanting the implant device comprises implanting the implant device into the lumen through the hole.

3. The method of claim 2 , wherein punching the hole comprises punching the implant device with the implantation device toward the lumen to cut the hole with the cutting edge and to position the implant device at least partially within the hole.

4. The method of claim 2 , wherein the hole comprises a first hole, wherein the method further comprises opening a second hole in the lumen with at least one opening unit of an opening device before the cutting edge punches the hole in the lumen in response to the effectuating the forward motion of the implantation device, the opening device being coupled to the implantation device.

5. The method of claim 4 , further comprising:
captively fixing a lumen section of the lumen with a barb of the opening unit; and
removing the lumen section from the lumen with barb while executing the return motion of the implantation device,
wherein punching the first hole in the lumen with the cutting edge comprises punching the lumen section of the lumen with the cutting edge.

6. The method of claim 4 , wherein the opening device is disposed at least partially in at least one of the implantation device or the implant device.

7. The method of claim 1 , wherein bringing about the opened state of the closure device to release a restoring force comprises releasing a restoring force of a spring of the closure device, and wherein releasing the restoring force of the spring of the closure device is configured to effectuate the forward motion of the implantation device.

8. The method of claim 1 , wherein the implantation device comprises:
at least one inner sleeve being configured to guide the implant device; and
an outer sleeve being configured to surround the implant device and to surround the inner sleeve in an at least partially linearly movable manner.

9. The method of claim 8 , wherein executing the return motion comprises utilizing the outer sleeve to carry out the return motion.

10. The method of claim 1 , wherein the implant device comprises a mesh having shape memory.

11. The method of claim 1 , wherein:
the closure device comprises a bayonet lock including a rotatable rotary element and a rotatable and linearly movable linear unit, and
a spring is loaded in a closed state of the bayonet lock in order to generate the restoring force.

12. The method of claim 11 , wherein bringing about the opened state of the closure device comprises transferring the bayonet lock from the closed state into the opened state by rotating the rotary element, and wherein effectuating the forward motion of the implantation device comprises executing a linear opening motion of the linear unit in a direction of an outlet opening of a punching device when the bayonet lock is transferred into the opened state.

13. The method of claim 11 , wherein, in order to couple the closure device to the implantation device, at least one sleeve of the implantation device comprises at least one pin to be accommodated in at least one guide groove of the rotatable and linearly movable linear unit and/or the rotatable and linearly movable linear unit comprises at least the guide groove for accommodating the pin of the sleeve, and wherein the guide groove and the pin are configured such that, in the coupled state, the guide groove and the pin effectuate the return motion of the implantation device in response to the actuation of the actuation device after the lumen has been punched.

14. The method of claim 1 , wherein the actuation device comprises at least one rotary knob configured to effectuate the at least one actuation of the actuation device in response to a rotary actuation.

15. The method of claim 1 , wherein the actuation device comprises at least one push-button configured to effectuate the at least one actuation of the actuation device in response to a push actuation.

16. The method of claim 1 , wherein at least the implant device and the implantation device are disposed on one axis.

17. The method of claim 1 , wherein the lumen is one of a blood vessel, a stomach, an intestine, or a trachea.

18. The method of claim 17 , wherein the lumen is a blood vessel.
