Device and method for sealing a puncture in a blood vessel
First Claim
1. A sealing device for a puncture in a blood vessel, the device being slidingly receivable over a guide tube and comprising a tubular, resilient sealing member formed with a sealing portion spontaneously sealable upon deployment of the device into an activated state, an engaging portion for beating against an external surface of the blood vessel and a plurality of anchors fitted at their fore end with fasteners for engaging a corresponding internal she of the blood vessel and at a rear end with a manipulating bit;
- said anchors being displaceable between a constricted position in which they blend with the tubular sealing member, and an to operative position in which the fasteners are lateral expanded and engage the internal surface of the blood vessel.

Abstract
A sealing device for a puncture in a blood vessel, device being slidingly receivable over a guide tube and comprising a tubular, resilient sealing member formed with a sealing portion spontaneously sealable upon deployment of the device into an activated state, an engaging portion for bearing against an external surface of the blood vessel and a plurality of anchors fitted at their fore end with fasteners for engaging a corresponding internal surface of the blood vessel and at a rear end with a manipulating bit. The anchors being displaceable between a constricted position in which they blend with the tubular sealing member, and an operative position in which the fasteners are laterally expanded and engage the internal surface of the blood vessel.

29. A method for sealing a puncture in a blood vessel, the method comprising the following steps:
-
(a) obtaining a sealing assembly comprising a sealing member fitted within an associated deploying assembly, with a sleeve extending through the sealing assembly, said sleeve defining a through-going path;
(b) introducing a medical guide tube through the path;
(c) removing the sleeve;
(d) carrying out a medical procure through the guide tube;
(e) slidingly displacing the sealing assembly over the guide tube until a fore end of the deploying assembly engages the blood vessel;
(f) expelling the sealing assembly from the deploying assembly and introducing anchor fastener members of the sealing assembly into the blood vessel through the puncture;
(g) deploying anchor faster members into an operative position in which they are laterally expanded and engage the internal surface of the blood vessel;
(h) disengaging the sealing assembly from the deploying assembly and withdrawing the guide tube, allowing a resilient sealing member formed in the sealing member to spontaneously seal. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37)
(a) axially displacing the controller within the housing in a forward direction;
(b) axially displacing the pusher within the controller.
-
-
35. A method according to claim 34, wherein the controller and housing are thread-engaged whereby step (a) is carried out by rotating the controller within the housing.
-
36. A method according to claim 34, wherein a fore end of the pusher member is formed with activating surfaces adapted for engagement with corresponding manipulating bits formed at rear ends of the anchors, whereby deploying the anchors into the operative position of step (g) is carried out by rotating the pusher within the housing.
-
37. A method according to claim 29, which after step (f) spear members are engaged with an external surface of the blood vessel surrounding to puncture and by applying inwardly directed radial force, the lips of the punctured blood vessel are adjoined, thereby decreasing the size of the puncture.
