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 method of repairing a hernia defect, the method comprising acts of:
(a) delivering a prosthesis in a reduced configuration through a surgical opening into a patient, the prosthesis including a patch body and a deployment device, the deployment device including a self-expanding support body and a handle coupled to the support body, the support body including a first side and a second side opposite the first side, the handle including a distal end coupled to the support body and a free end opposite the distal end, the support body being releasably coupled to the patch body to assist in spreading the patch body to an expanded configuration;
(b) following act (a), spreading the patch body to the expanded configuration via the support body;
(c) securing the patch body in the expanded configuration about the hernia defect;
(d) following act (c), removing the support body from the pocket of the patch body by directing an outward pulling force applied with the free end of the handle from above the first side to a location at or in close proximity to an outer periphery of the support body causing a portion of the support body proximate to the outer periphery to collapse inwardly toward the patch body and become tucked below the second side of the support body; and
(e) withdrawing the deployment device through the surgical opening out of the patient.

2. The method according to claim 1 , wherein the patch body includes a pocket and an access opening to the pocket, the support body being removably inserted in the pocket with the handle extending through the access opening, the support body being collapsible for insertion into and removal from the pocket, and wherein act (d) includes removing the support body from the pocket of the patch body.

3. The method according to claim 2 , wherein act (c) includes delivering fasteners through the pocket of the patch body.

4. The method according to claim 3 , wherein act (c) includes delivering one or more sutures, tacks, clips, staples, coils and/or screws through the pocket of the patch body.

5. The method according to claim 1 , wherein act (d) includes collapsing the support body to a non-conical configuration.

6. The method according to claim 1 , wherein acts (d) and (e) include pulling the free end of the handle from outside the patient.

7. The method according to claim 1 , wherein act (d) includes applying the pulling force from the handle to the second side of the support body.

8. The method according to claim 7 , wherein a portion of the handle extends through the support body to apply the pulling force to the second side of the support body.

9. The method according to claim 1 , wherein act (d) includes bending the portion of the support body downwardly and in a direction toward a central portion of the support body.
