Method and device for sealing a puncture hole in a bodily organ
View Patent ↗A method for sealing a hole in a bodily organ includes introducing a first member and a second member into the bodily organ, the first and second members being connected by an elongated member. The first and second members are retracted proximally until the first member abuts an inner surface of the bodily organ and the second member is retracted out of the hole in the bodily organ. Then, the second member is pushed distally into abutment with an outer surface of the bodily organ. A sealing device for sealing a puncture in tissue is also described.
1. A device for sealing a puncture hole in a bodily organ, the device comprising:
an inner member adapted for positioning against an inner surface of the bodily organ;
an outer member adapted for positioning against a corresponding outer surface of the bodily organ; and
an elongated retaining member;
wherein the inner member is arranged at a distal end of the elongated retaining member and the outer member is movable along the elongated retaining member,
wherein the outer member in a first state is arranged to have a first dimension enabling, after having been deployed inside the bodily organ through the puncture hole, retraction of the outer member out of the puncture hole,
wherein the outer member has a compressible and resilient structure such that the outer member is reducible in size in a radial direction of the outer member when in the first state,
wherein the outer member is arranged to be engaged in a locking arrangement with the elongated retaining member such that the outer member can be moved distally along the elongated retaining member and fixed in a locked position at the outer surface of the bodily organ,
wherein the outer member in a second state is arranged to have a second dimension enabling sealing of the puncture hole by at least one of the inner member and the outer member when in the locked position,
wherein the outer member has a first through-hole and a second through-hole,
wherein the elongated retaining member passes through the first and second through-holes, and
wherein, when in an undeformed condition, the outer member has the first through-hole extending in a longitudinal direction and the second through-hole extending in a direction perpendicular to the longitudinal direction.
2. A device as set forth in claim 1 , wherein the outer member is substantially free of haemostatic material.
3. A device as set forth in claim 1 , wherein the first through-hole is disposed at a proximal end of the outer member and the second through-hole is disposed at a distal end of the outer member.
4. A device as set forth in claim 1 , wherein an outer profile of the outer member gradually increases along a length of the outer member from a proximal end of the outer member to a distal end of the outer member.
5. A device as set forth in claim 1 , wherein the outer member is configured to fold onto itself.
6. A device as set forth in claim 1 , wherein the outer member includes an angled portion configured to assist in folding the outer member.
7. A device for sealing a puncture hole in a bodily organ, the device comprising:
an inner member adapted for positioning against an inner surface of the bodily organ;
an outer member adapted for positioning against a corresponding outer surface of the bodily organ; and
an elongated retaining member,
wherein the inner member is arranged at a distal end of the elongated retaining member and the outer member is movable along the elongated retaining member,
wherein the outer member has a compressible and resilient structure such that the outer member is reducible in size in a radial direction of the outer member, thereby enabling, after having been deployed inside the bodily organ through the puncture hole, retraction of the outer member out of the puncture hole,
wherein the outer member is arranged to be engaged in a locking arrangement with the elongated retaining member such that the outer member can be moved distally along the elongated retaining member and fixed in a locked position at the outer surface of the bodily organ to thereby enable sealing of the puncture hole by at least one of the inner member and the outer member,
wherein the outer member has a first through-hole and a second through-hole,
wherein the elongated retaining member passes through the first and second through-holes, and
wherein, when in an undeformed condition, the outer member has the first through-hole extending in a longitudinal direction and the second through-hole extending in a direction perpendicular to the longitudinal direction.
8. A device as set forth in claim 7 , wherein the outer member includes an angled portion configured to assist in folding the outer member.
9. A device as set forth in claim 7 , wherein the outer member is substantially free of haemostatic material.
10. A device as set forth in claim 7 , wherein the first through-hole is disposed at a proximal end of the outer member and the second through-hole is disposed at a distal end of the outer member.
11. A device as set forth in claim 7 , wherein an outer profile of the outer member gradually increases along a length of the outer member from a proximal end of the outer member to a distal end of the outer member.
12. A device as set forth in claim 7 , wherein the outer member is configured to fold onto itself.
