Vascular hole closure delivery device
First Claim
1. A method of delivering a vascular hole closure device to a vessel, the method comprising:
- providing a vascular hole closure device having a covering member, a first retainer, a first flexible member extending between the covering member and first retainer and a first engagement member extending from the first flexible member;
providing a delivery instrument containing the first flexible member;
inserting a distal portion of the delivery instrument into the vessel;
exposing the covering member for placement inside the vessel; and
moving the delivery instrument proximally in a direction away from the covering member until the first engagement member is forced pass a first stop and comes into contact with a second stop within the delivery instrument to move the first retainer distally toward the covering member.

Abstract
A surgical delivery instrument for delivering a vascular hole closure device having first and second flexible members and a first and second engagement members extending from the respective flexible member. The delivery instrument includes a housing having first and second longitudinally extending openings and first and second projecting surfaces, the first projecting surface extending into the first opening for engagement by the first engagement member and the second projecting surface extending into the second opening for engagement by the second engagement member. The first engagement member is held by the first projecting surface until a predetermined force is applied to the first engagement member during placement of the closure device at a target site.

12. A method of delivering a vascular hole closure device to a vessel, the method comprising:
-
providing a delivery instrument having a first lumen to receive a first flexible member and a second lumen to receive a second flexible member; inserting a distal portion of the delivery instrument into the vessel to deliver a first portion of the vascular hole closure device internal of the vessel; moving the delivery instrument proximally in a direction away from the vessel to initially pull the first flexible member proximally and subsequently pull the second flexible member proximally, wherein pulling of the first and second flexible members advances extravascular portions of the vascular closure device toward the vessel;
wherein the delivery instrument includes a first reduced cross sectional area and movement of the first flexible member proximally is restricted by the first reduced cross-sectional area until a sufficient proximal force in a direction away from the vessel is applied; and
wherein the delivery instrument includes a second reduced cross sectional area and movement of the second flexible member proximally is restricted by the second reduced cross sectional area until a sufficient proximal force in a direction away from the vessel is applied. - View Dependent Claims (13, 14, 15, 16, 17, 18)
