Abstract

A medical device and methods for hemostasis in a living body are disclosed. The medical device including a base configured to arranged on an upper surface of the tissue in the living body; a plurality of levers, each of the plurality of levers having a needle arranged on a lower surface thereof and configured to puncture the tissue in the living body, and wherein the plurality of lever are configured to be received with a slot or track of the base; and at least one tie, the at least one tie configured to hold together the plurality levers and needles upon compressing the tissue in the living body upon moving the plurality of levers inward in the slot or track of the base.

First claim

The invention claimed is:

1. A system for hemostasis in a living body, the system comprising:
a medical device comprising:
a base configured to be arranged on an upper surface of the tissue in the living body, the base including one or more openings extending inward from an outer edge of the base;
a plurality of levers, each of the plurality of levers having a needle arranged on a lower surface of the plurality of levers and configured to puncture the tissue in the living body, and wherein the plurality of levers are configured to be received in a slot or track of the base; and
at least one tie, the at least one tie configured to hold together the plurality levers and needles upon compressing the tissue in the living body upon moving the plurality of levers inward in the slot or track of the base; and

at least one medical sheath or catheter configured to be arranged in the one or more openings of the base.

2. The system according to claim 1 , wherein the plurality of levers are four, and the at least one tie is a pair of ties.

3. The system according to claim 1 , further comprising:
a locking member, the locking member configured to secure the at least one tie.

4. The system according to claim 1 , wherein each of the needles has a length of about 5 mm to 20 mm from the lower surface of the lever.

5. The system according to claim 1 , wherein each of the plurality of needles has an angled tip, and wherein the angled tip points inward towards a center of the medical device.

6. The system according to claim 1 , wherein the base is a rectangular plate, the one or more openings configured to receive the at least one medical sheath or catheter such that the at least one medical sheath or catheter can pass through the medical device and the medical device can be placed over an inserted sheath or catheter.

7. The system according to claim 1 , wherein the at least one tie is a single loop tie.

8. The system according to claim 1 , wherein the slot or track of the base is arranged on a lower surface of the base and the plurality of levers disengage from the base upon reaching a center of the base.

9. The system according to claim 8 , wherein at least a portion of the base disengages with the plurality of levers upon reaching the center of the base.

10. The system according to claim 8 , wherein the one or more openings extending inward from the outer edge of the base are wedge shaped.

11. A method of achieving hemostasis with the system according to claim 1 , the method comprising:
puncturing the tissue in the living body with the plurality of needles of the medical device;
compressing the tissue in the living body by gathering the plurality of needles; and
locking the plurality of needles together.

12. The method according to claim 11 , wherein each of the plurality of needles are L-shaped needles.

13. The method according to claim 11 , comprising:
removing the base after compressing the tissue in the living body by gathering the plurality of needles or locking the plurality of needles together.

14. A system for hemostasis in a living body, the system comprising:
a medical device comprising:
a rectangular base configured to be arranged on an upper surface of the tissue in the living body, the rectangular base including a pair of wedge shaped openings extending inward from an outer edge of the rectangular base;
a plurality of levers, each of the plurality of levers having a needle arranged on a lower surface of the plurality of levers and configured to puncture the tissue in the living body, and wherein the plurality of levers are configured to be received in a slot or track of the rectangular base; and
at least one tie, the at least one tie configured to hold together the plurality levers and needles upon compressing the tissue in the living body upon moving the plurality of levers inward in the slot or track of the rectangular base; and

at least one medical sheath or catheter configured to be arranged in the one or more openings of the rectangular base.

15. The system according to claim 14 , wherein the plurality of levers are four, and the at least one tie is a pair of ties.

16. The system according to claim 14 , further comprising:
a locking member, the locking member configured to secure the at least one tie.

17. The system according to claim 14 , wherein each of the needles has a length of about 5 mm to 20 mm from the lower surface of the lever.

18. The system according to claim 14 , wherein each of the plurality of needles has an angled tip, and wherein the angled tip points inward towards a center of the medical device.

19. The system according to claim 14 , wherein the at least one tie is a single loop tie.

20. The system according to claim 14 , wherein the slot or track of the rectangular base is arranged on a lower surface of the rectangular base and the plurality of levers disengage from the rectangular base upon reaching a center of the rectangular base.

21. The system according to claim 20 , wherein at least a portion of the rectangular base disengages with the plurality of levers upon reaching the center of the rectangular base.

22. A system for hemostasis in a living body, the system comprising:
a medical device comprising:
a rectangular base configured to be arranged on an upper surface of the tissue in the living body, the rectangular base including one or more wedge shaped openings extending inward from an outer edge of the rectangular base;
a plurality of levers, each of the plurality of levers having a needle arranged on a lower surface of the plurality of levers and configured to puncture the tissue in the living body, and wherein the plurality of levers are configured to be received in a slot or track of the rectangular base; and
at least one tie, the at least one tie configured to hold together the plurality levers and needles upon compressing the tissue in the living body upon moving the plurality of levers inward in the slot or track of the rectangular base; and

at least one medical sheath or catheter configured to be arranged in the one or more wedge shaped openings of the rectangular base.
