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.
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 and a second retainer;providing a delivery instrument containing the first retainer and second retainer;inserting a distal
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 and a second retainer;providing a delivery instrument containing the first retainer and second retainer;inserting a distal portion of the delivery instrument into the vessel;placing the covering member inside the vessel; andmoving the delivery instrument proximally in a direction away from the placed covering member to initially advance the first retainer toward the covering member and subsequently advance the second retainer toward the covering member;wherein the first retainer is connected to a first flexible connecting member and the second retainer is connected to a second flexible connecting member, and further continued proximal movement of the delivery instrument severs the first and second flexible connecting members. 2. The method of claim 1, wherein continued movement of the delivery instrument proximally in a direction away from the covering member further advances the first retainer toward the covering member after the second retainer is advanced toward the covering member. 3. The method of claim 1, wherein the covering member is positioned within the delivery instrument during insertion and the step of placing the covering member inside the vessel includes the step of exposing the covering member from the delivery instrument for placement inside the vessel. 4. The method of claim 3, wherein the covering member pivots from a more longitudinally aligned position within the delivery instrument to a transverse position inside the vessel. 5. The method of claim 1, wherein the covering member, first and second retainers and first and second flexible connecting members are composed of a resorbable material and left in a body of a patient for resorption. 6. The method of claim 1, wherein the delivery instrument includes a cutting member positioned therein to sever the first and second flexible connecting members. 7. The method of claim 1, wherein the delivery instrument includes a first channel and a second channel, and the first flexible connecting member moves in the first channel and the second flexible connecting member moves in the second channel. 8. The method of claim 7, wherein the delivery instrument includes a first distal opening at the first channel and a second distal opening at the second channel, the first flexible connecting member extending through the first distal opening and the second flexible connecting member extending through the second distal opening. 9. The method of claim 1, wherein the first retainer is fixedly attached to the first flexible connecting member at a first portion and the second retainer is fixedly attached to the second flexible connecting member at a second portion such that proximal movement of a third portion of the first flexible connecting member advances the first retainer toward the covering member and proximal movement of a fourth portion of the second flexible connecting member advances the second retainer toward the covering member. 10. The method of claim 1, wherein the covering member against a wall of the vessel applies a counterforce to effect advancement of the first and second retainers toward the covering member. 11. The method of claim 1, wherein movement of the delivery instrument proximally in a direction away from the covering member causes sequential engagement with engagement members within the delivery instrument. 12. The method of claim 1, wherein the first and second retainers are placed external of the vessel. 13. The method of claim 12, wherein the extent of advancement of the first and second retainers is dependent on a thickness of tissue external of the vessel. 14. The method of claim 1, wherein the first and second retainers are in a stacked relationship within the delivery instrument. 15. A method of delivering a vascular hole closure device to a vessel in a body of a patient, the method comprising: providing a vascular hole closure device having a covering member, a first retainer fixed to a first connecting member and a second retainer fixed to a second connecting member;providing a delivery instrument containing a cutting member, the first and second retainers, and the first and second connecting members;inserting a distal portion of the delivery instrument into the vessel;placing the covering member in the body of the patient; andmoving the delivery instrument proximally in a direction away from the placed covering member, wherein the step of moving the delivery instrument proximally causes severing of the first and second connecting members by the cutting member. 16. The method of claim 15, wherein the step of moving the delivery instrument proximally advances the first retainer and the second retainer toward the covering member. 17. The method of claim 15, wherein the step of moving the delivery instrument proximally initially advances the first retainer toward the covering member and subsequently advances the second retainer toward the covering member.
