Abstract

A delivery device for delivering a plurality of individual surgical anchors is disclosed. The delivery device includes a housing, a delivery tube, having a distal and a proximal end, an actuator, flexible anchor reaction members, a reciprocating anchor carrier, having a distal and a proximal end, the distal end terminating in a tissue penetrator. The device further includes at least one surgical anchor located in juxtaposition with the anchor carrier. Each of the surgical anchors has a penetration section and a head section. The surgical anchors are preferably made from an absorbable polymer. The actuator is connected to the anchor carrier and has at least two states. The first, or home state, is a position such that the surgical anchor is proximal the distal end of the tube. The second state is such that the penetrating section of the surgical anchor is exposed beyond the distal end of the delivery tube.

Claims

1. A delivery device for delivering surgical anchors, the delivery device comprising:

a. a housing,

b. a delivery tube with distal and proximal ends,

c. a reciprocating anchor carrier, with distal and proximal positions and distal and proximal ends, the distal end of the anchor carrier terminating in a tissue penetrator member, the reciprocating anchor carrier being moveable distally and proximally with respect to the delivery device,

d. a plurality of surgical anchors located within the delivery tube and radially about the anchor carrier, each surgical anchor having a penetration section and a head section, an actuator having at least two states, the first state causing the anchor carrier to be in its proximal-most position and the second state causing the anchor carrier to be in the distal-most position with a perimeter of the penetration section of the surgical anchor extending distally beyond the distal end of the delivery tube and being in contact with a target site.

2. The device of claim 1 where each of the plurality of surgical anchors is formed from one or more absorbable polymers.

3. The device of claim 1 where each of the plurality of surgical anchors includes a blunt distal end.

4. The device of claim 1 where each of the plurality of surgical anchors includes one or more slits for removal from the anchor carrier.

5. The device of claim 1 where each of the plurality of surgical anchors includes one or more barbs for engagement with the tissue.

6. The device of claim 1 where the delivery device includes a queuing spring.

7. The device of claim 1 where the delivery device includes at least two reaction members, each of the at least two reaction members extending radially inward and distally from an inner surface of the delivery tube.

8. A delivery device for delivering surgical anchors, the delivery device comprising:

a. a housing,

b. a delivery tube with distal and proximal ends, the delivery tube defining a lumen therethrough and defining an inner surface,

c. at least two reaction members fixed in respect to the delivery tube, each of the at least two reaction members extending radially inward and distally from the inner surface of the delivery tube, and

d. a reciprocating anchor carrier, with distal and proximal positions and distal and proximal ends, the distal end of the anchor carrier terminating in a tissue penetrator member, the reciprocating anchor carrier being moveable distally and proximally with respect to the delivery device.

9. The device of claim 8 further comprising at least one surgical anchor located radially about the anchor carrier each surgical anchor having a penetration section and a head section.

10. The device of claim 9 wherein each of the plurality of surgical anchors includes a blunt distal end.

11. The device of claim 9 wherein each of the plurality of surgical anchors includes one or more slits for removal from the anchor carrier.

12. The device of claim 9 wherein each of the plurality of surgical anchors includes one or more barbs for engagement with the tissue.

13. The device of claim 9 wherein the reaction members are configured to allow passage therebetween of the surgical anchor in a single direction.

14. The device of claim 8 wherein the delivery device includes a queuing spring.
