Appl. No.:

16/151926

Inventors:

- PHILADELPHIA PA, US
John Patrick Fischer - Philadelphia PA, US

Assignee:

THE TRUSTEES OF THE UNIVERSITY OF PENNSYLVANIA - PHILADELPHIA PA

International Classification:

A61F 2/00

Abstract:

Techniques for mesh augmentation and prevention of incisional hernia, including systems and methods for affixing mesh to a fascial incision. A mesh strip can be integrated with one or more uni-directional fasteners. Each fastener can include an anchoring mechanism adapted for affixation to anterior abdominal wall fascia and a mating interface. An applicator can include tension arms adapted to interface with the mating interfaces of the fasteners to maintain a vertical tension of the mesh strip and a handle coupled with the tension arms adapted to spread the tension arms and thereby control a horizontal tension of the mesh strip. The mesh strip can be configured to be aligned over a fascial incision using the applicator and affixed under tension to anterior abdominal wall fascia by tissue penetration of the anchoring mechanisms of the one or more fasteners.
