Abstract

A deployment device for positioning a soft tissue repair prosthesis includes a self-expanding support body releasably attachable to the prosthesis. The support body may be removably insertable into a pocket of the prosthesis. A handle coupled to the support body facilitates positioning the patch and/or removal of the support body from the pocket. The support body may substantially occupy the pocket in an expanded configuration. The handle may be arranged to direct a pulling force to the outer peripheral edge of the support body and/or cause a portion thereof to be pulled downward and below the body during withdrawal of the deployment device from the prosthesis. The support body may include support segments pivotally coupled together and foldable to collapse the support body for insertion into and removal from the pocket. One or more resilient support members may be provided for collapsing and expanding the support body and the prosthesis.

First claim

What is claimed is:

1. A deployment device for a soft tissue repair prosthesis, the deployment device comprising:
a self-expanding support body configured to be releasably coupled to the soft tissue repair prosthesis to assist in spreading the soft tissue repair prosthesis from a reduced configuration to an expanded configuration, the support body being collapsible from an expanded configuration to a reduced configuration, the support body including a first support segment and a separate second support segment, the first and second support segments coupled together at only two locations and in an alternating overlap arrangement between the two locations, each of the locations including only one connection between the first and second segments; and
a handle including a distal end and a free end opposite the distal end, the distal end of the handle coupled to the support body to position the soft tissue repair prosthesis relative to a soft tissue defect when the support body is coupled to the soft tissue repair prosthesis and to release the support body from the soft tissue repair prosthesis with a pulling force on the free end of the handle in an outward direction away from the soft tissue repair prosthesis when the soft tissue repair prosthesis is in the expanded configuration,
wherein the support body is manipulable into the reduced configuration with the soft tissue repair prosthesis for insertion through a surgical opening into a patient.

2. The deployment device according to claim 1 , wherein the first and second support segments are pivotally coupled together with one pivot at each of the two locations, portions of the first and second support segments alternately overlapping each other at the pivots.

3. The deployment device according to claim 2 , wherein the support body has a first axis and a second axis perpendicular to the first axis, the first axis and the second axis intersecting at approximately a center of the support body, the pivots being located in a pivot plane located along the second axis and perpendicular to the first axis.

4. The deployment device according to claim 3 , wherein the pivots are located on opposite sides of the first axis.

5. The deployment device according to claim 4 , wherein the first and second support segments pivot relative to each other about pivot axes located in the pivot plane.

6. The deployment device according to claim 5 , wherein the first and second support segments are configured to fold or bend as the first and second segments pivot relative to each other.

7. The deployment device according to claim 3 , wherein the first and second support segments are configured to fold or bend about the first axis.

8. The deployment device according to claim 3 , wherein the handle includes a handle base and a handle pull extending from the handle base, the first and second support segments being pivotally coupled to the handle base.

9. The deployment device according to claim 8 , wherein the handle base is configured to fold or bend to facilitate removal of the support body from the soft tissue repair prosthesis.

10. The deployment device according to claim 8 , wherein the handle pull is configured to pivot toward and away from the support body along at least the first axis.

11. A deployment device for a soft tissue repair prosthesis, the deployment device comprising:
a self-expanding support body to be releasably coupled to the soft tissue repair prosthesis to assist in spreading the soft tissue repair prosthesis from a reduced configuration to an expanded configuration, the support body being collapsible from an expanded configuration to a reduced configuration, the support body including a first support segment and a second support segment, the first and second support segments coupled together in an alternating overlap arrangement; and
a handle including a distal end and a free end opposite the distal end, the distal end of the handle coupled to the support body to position the soft tissue repair prosthesis relative to a soft tissue defect when the support body is coupled to the soft tissue repair prosthesis and to release the support body from the soft tissue repair prosthesis with a pulling force on the free end of the handle in an outward direction away from the soft tissue repair prosthesis when the soft tissue repair prosthesis is in the expanded configuration,
wherein the support body is manipulable into the reduced configuration with the soft tissue repair prosthesis for insertion through a surgical opening into a patient, wherein the expanded configuration of the support body has a planar configuration and the reduced configuration of the support body has a non-planar configuration.

12. A deployment system for a soft tissue repair prosthesis, the deployment system comprising:
a soft tissue repair prosthesis, wherein the soft tissue repair prosthesis comprises a patch body including a pocket and an access opening configured to provide access to the pocket; and
a deployment device for the soft tissue repair prosthesis, the deployment device comprising:
a self-expanding support body to be releasably coupled to the soft tissue repair prosthesis to assist in spreading the soft tissue repair prosthesis from a reduced configuration to an expanded configuration, the support body being collapsible from an expanded configuration to a reduced configuration, the support body including a first support segment and a second support segment, the first and second support segments coupled together in an alternating overlap arrangement; and
a handle including a distal end and a free end opposite the distal end, the distal end of the handle coupled to the support body to position the soft tissue repair prosthesis relative to a soft tissue defect when the support body is coupled to the soft tissue repair prosthesis and to release the support body from the soft tissue repair prosthesis with a pulling force on the free end of the handle in an outward direction away from the soft tissue repair prosthesis when the soft tissue repair prosthesis is in the expanded configuration,
wherein the support body is manipulable into the reduced configuration with the soft tissue repair prosthesis for insertion through a surgical opening into a patient,
wherein the support body is configured to be removably inserted into the pocket through the access opening to assist in spreading the patch body from the reduced configuration to the expanded configuration, the support body being insertable into and removable from the pocket when collapsed from the expanded configuration to the reduced configuration, and
wherein the free end of the handle is extendable away from the support body and through the access opening when the support body is removably inserted in the pocket of the patch body for positioning the patch body relative to the hernia defect, the support body being removable from the pocket with a pulling force on the free end of the handle in an outward direction away from the patch body when the patch body is in the expanded configuration.

13. The deployment system according to claim 12 , wherein the patch body includes first and second layers attached together to form the pocket therebetween, one of the first and second layers including the access opening therethrough to provide access to the pocket.

14. A deployment device for a soft tissue repair prosthesis, the deployment device comprising:
a self-expanding support body to be releasably coupled to the soft tissue repair prosthesis to assist in spreading the soft tissue repair prosthesis from a reduced configuration to an expanded configuration, the support body including a
