Abstract

Embodiments of the invention provide systems, apparatus, device and methods for sealing a puncture in a tissue wall. According to one aspect, the system includes at least one supporting element for insertion into or placement on at least a portion of a tissue wall proximate a puncture to prevent expansion of the puncture; and a closing element adapted for at least partial insertion into the tissue wall and shaped to compress at least a portion of a tissue wall in an inward direction to close the tissue puncture when inserted at least partially into the tissue wall.

Claims

1. A system comprising:

an attaching device comprising;

a port defining an opening extending along a longitudinal axis defined by the attaching device, and

a coil attached to the port and configured for advancing at least partially into a tissue wall such that at least a portion of the coil becomes disposed between a first surface and a second surface of the tissue wall; and

an occluding device comprising;

an engagement mechanism configured for removably interlocking the occluding device and the attaching device such that the occluding device is fixed relative to the port of the attaching device along the longitudinal axis defined by the attaching device when the occluding device and the attaching device are interlocked, and

a valve being positioned at least partially within the coil and occluding the opening of the port when the occluding device and the attaching device are interlocked.

2. The system of claim 1, wherein the coil has a radially expanding helical shape.

3. The system of claim 2, wherein the coil comprises a proximal end and a distal end, wherein the proximal end is attached to the port, and wherein a radius of the coil increases along at least a portion of a length of the coil from the proximal end to the distal end.

4. The system of claim 1, wherein the coil comprises a proximal end and a distal end, wherein the proximal end is attached to the port, and wherein a radius of the coil is substantially constant along a length of the coil from the proximal end to the distal end.

5. The system of claim 1, wherein the coil is configured to compress at least a portion of the tissue wall in an inward direction toward the longitudinal axis defined by the attaching device.

6. The system of claim 1, wherein the port comprises a flange extending about the opening and configured for engaging the tissue wall.

7. The system of claim 6, wherein the flange has a flat, annular shape.

8. The system of claim 1, wherein the valve comprises a one-way valve configured to yield to pressure applied to a proximal end of the valve.

9. The system of claim 1, wherein the engagement mechanism comprises threads configured for removably engaging mating threads of the attaching device.

10. The system of claim 9, wherein the threads are positioned about a proximal end of the occluding device, and wherein the mating threads are positioned about a proximal end of the attaching device.

11. The system of claim 1, wherein the engagement mechanism comprises a locking collar configured for removably engaging a mating collar of the attaching device.

12. The system of claim 11, wherein the locking collar is positioned about a proximal end of the occluding device, and wherein the mating collar is positioned about a proximal end of the attaching device.

13. The system of claim 1, wherein the occluding device further comprises an engagement element configured for releasably receiving a delivery instrument for insertion of the occluding device at least partially within the opening of the port.

14. The system of claim 13, wherein the engagement element is positioned about a proximal end of the occluding device.

15. The system of claim 13, wherein the engagement element comprises a slot configured for releasably receiving a distal end of the delivery instrument.

16. A system comprising:

an attaching device comprising;

a port defining an opening extending along a longitudinal axis defined by the attaching device, and

a coil attached to the port and configured for advancing at least partially into a tissue wall such that at least a portion of the coil becomes disposed between a first surface and a second surface of the tissue wall; and

an occluding device comprising;

a locking collar configured for removably engaging a mating collar of the attaching device such that the occluding device is fixed relative to the port of the attaching device along the longitudinal axis defined by the attaching device when the locking collar and the mating collar are engaged, and

a valve being positioned at least partially within the coil and occluding the opening of the port when the locking collar and the mating collar are engaged.

17. The system of claim 16, wherein the locking collar is positioned about a proximal end of the occluding device, and wherein the mating collar is positioned about a proximal end of the attaching device.

18. The system of claim 16, wherein the valve comprises a one-way valve configured to yield to pressure applied to a proximal end of the valve.

19. A system comprising:

an attaching device comprising;

a port defining an opening extending along a longitudinal axis defined by the attaching device; and

a coil attached to the port and configured for advancing at least partially into a tissue wall such that at least a portion of the coil becomes disposed between a first surface and a second surface of the tissue wall, wherein the coil comprises a proximal end and a distal end, wherein the proximal end is attached to the port, wherein a radius of the coil increases along at least a portion of a length of the coil from the proximal end to the distal end; and

an occluding device comprising;

a locking collar configured for removably engaging a mating collar of the attaching device such that the occluding device is fixed relative to the port of the attaching device along the longitudinal axis defined by the attaching device when the locking collar and the mating collar are engaged; and

a valve extending distally beyond the locking collar, the valve being positioned at least partially within the coil and occluding the opening of the port when the locking collar and the mating collar are engaged.

20. The system of claim 19, wherein the locking collar is positioned about a proximal end of the occluding device, and wherein the mating collar is positioned about a proximal end of the attaching device.
