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 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 an outer periphery, a first side and a second side opposite the first side, the support body being collapsible from an expanded configuration to a reduced configuration; 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, the distal end of the handle being coupled to a portion of the support body proximate to the outer periphery to apply the pulling force with the free end of the handle from above the first side and cause the portion of the support body to collapse in an inward direction toward the soft tissue repair prosthesis and become tucked below the second side,
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 expanded configuration of the support body has a planar configuration and the reduced configuration of the support body has a non-planar configuration.

3. The deployment device according to claim 1 , wherein the support body is formed as a single piece structure.

4. The deployment device according to claim 1 , wherein the support body includes a resilient support member to support the support body in the expanded configuration.

5. The deployment device according to claim 4 , wherein the resilient support member extends along the outer periphery of the support body.

6. The deployment device according to claim 1 , 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 support body including first and second portions on opposite sides of the second axis, the handle being coupled to the second portion of the support body along the first axis.

7. The deployment device according to claim 6 , wherein the handle extends in a direction parallel to the first axis.

8. The deployment device according to claim 6 , wherein the handle is located along the first axis.

9. The deployment device according to claim 6 , wherein the handle extends through the second portion of the support body.

10. The deployment device according to claim 9 , wherein a first portion of the handle is located adjacent the first side of the support body and a second portion of the handle being located adjacent the second side of the support body.

11. The deployment device according to claim 1 , wherein the soft tissue repair prosthesis comprises a patch body including a pocket and an access opening configured to provide access to the pocket,
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, 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.

12. The deployment device according to claim 11 , in combination with the soft tissue repair prosthesis.

13. The deployment device in combination with the soft tissue repair prosthesis 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. The deployment device in combination with the soft tissue repair prosthesis according to claim 12 , wherein the pocket has an outer periphery and the support body includes an outer peripheral edge along the outer periphery thereof, the outer peripheral edge of the support body configured to follow the outer periphery of the pocket.

15. The deployment device in combination with the soft tissue repair prosthesis according to claim 12 , wherein the support body is configured to substantially occupy the pocket.
