Tool, a sealing device, a system and a method for closing a wound
First Claim
1. A tool (101;
-
102) for inserting and mating two bioabsorbable plug members (2, 3) of a sealing device (1) for closing a wound in the wall of a blood vessel, one bioabsorbable plug member of the sealing device being a bioabsorbable distal plug member (2) to be positioned inside the blood vessel and the other bioabsorbable plug member being a bioabsorbable proximal plug member (3) to be positioned outside of the blood vessel, the bioabsorbable distal plug member being provided with an elongated retracting means (6) extending from the bioabsorbable distal plug member, whereinthe tool comprises a gear mechanism (32;
132) coupled to the retracting means for converting a movement of the tool in a proximal direction away from the wound, when the bioabsorbable distal plug member is anchored in the blood vessel, to a pushing movement for moving the bioabsorbable proximal plug member in a direction towards the bioabsorbable distal plug member, the pushing movement being induced by a stretching force (F1) in the retracting means.

Abstract
A tool (101) is provided for inserting and mating two plug members (2, 3) of a sealing device (1) for closing a wound in the wall of a vessel by placing the distal plug member (2) of the sealing device inside the vessel and the proximal plug member (3) on the outside of the vessel. The distal plug member is provided with an elongated retracting means (6) extending from the distal plug member. The tool comprises a gear mechanism (32) coupled to the retracting means for converting a movement of the tool in a proximal direction away from the wound (22), when the distal plug member is anchored in the vessel (20), to a pushing movement for moving the proximal plug member in a direction towards the distal plug member in response to a stretching force in the retracting means.

7. A method for closing a wound in a punctured blood vessel with a tool, comprising:
-
inserting and mating two plug members (2, 3) of a sealing device (1), one plug member of the sealing device being a distal plug member (2) to be positioned inside the blood vessel and the other plug member being a proximal plug member (3) to be positioned outside of the blood vessel, the distal plug member being provided with an elongated retracting means (6) extending from the distal plug member;
positioning the distal plug member (2) inside the blood vessel with the retracting means (6) being attachable to the tool comprising a gear mechanism (32;
132) connectable to the retracting means for converting a movement of the tool in a proximal direction away from the wound, to a pushing movement for moving the proximal plug member in a direction towards the distal plug member in response to a stretching force (F1) in the retracting means when the distal plug member is anchored in the blood vessel; and
withdrawing the tool (101;
102) with the retracting means attached thereto to stretch the retracting means, thereby activating the gear mechanism to approach the proximal plug member towards the distal plug member via a feeding means (34;
134). - View Dependent Claims (8)

9. A system for closing a wound in a punctured blood vessel, comprising:
-
obtaining a sealing device comprising;
a distal resiliently expandable plug member (2) having an elongated retracting means extending centrally from a distal plug member and including a portion (10) for attaching a proximal plug member (3) of the sealing device, the proximal plug member being resiliently expandable and being adapted to be mounted onto the distal plug member to be fixed thereto by means of the attaching portion, wherein the proximal plug member comprises a through bore (9), the distal plug member comprises a through bore (8), and a suture (6) is passed through said bore (8) to serve as the retracting means by providing an enlarged portion at one end as a counter when pulling the suture; and
inserting and mating the sealing device using a tool, the tool comprising;
a gear mechanism coupled to the retracting means for converting a movement of the tool in a proximal direction away from the wound, when the distal plug member is anchored in a blood vessel, to a pushing movement for moving the proximal plug member in a direction toward the distal plug member, the pushing movement being induced by a stretching force in the retracting means.

102) for closing a wound by positioning a bioabsorbable distal plug inside a blood vessel and a bioabsorbable proximal plug positioned outside of the blood vessel, comprising;
a casing; and
a movement direction reverser (32;
132) adapted to be coupled to a retractor which is coupled to the bioabsorbable distal plug, wherein the movement direction reverser, when coupled to the retractor, is adapted to convert movement of the casing in a proximal direction away from the wound when the bioabsorbable distal plug is anchored in the blood vessel to a pushing movement to move the bioabsorbable proximal plug in a direction towards the bioabsorbable distal plug, the pushing movement to move the bioabsorbable proximal plug being induced by a tension force imparted on the retractor. - View Dependent Claims (11, 12, 13, 14, 15, 16)
