  • Patent number: 11051932
    Abstract: An implant delivery system for delivering a sheet-like implant is disclosed. The implant delivery system includes a distal guidewire port for receiving the proximal end of guidewire after the guidewire distal end has been affixed to a first point on bone or other tissue. The implant delivery system is tracked over the guidewire to a selected position defined by the guidewire attachment. The device includes an implant spreader assembly disposed proximate the distal end of a delivery shaft. The implant spreader assembly includes a first arm and a second arm. The arms are coupled to the delivery shaft such that the first arm and second arm are moveable between a closed position and an open position. When pivoting to the open position the distal end of each arm travels in a generally transverse direction to spread a sheet-like implant.

  • Patent number: 11051808
    Abstract: A staple for attaching a sheet-like implant to tissue or bone may include first and second arms, and first and second flukes. In some embodiments, the first arm has a proximal end and a distal end, and the second arm has a proximal end and a distal end. A bridge extends from the proximal end of the first arm to the proximal end of the second arm. The first fluke has a proximal end abutting the distal end of the first arm, and the first fluke extends distally from the first arm. The first fluke has a lateral extent larger than a lateral extent of the first arm and is mounted eccentrically thereto. The first fluke includes a proximal surface projecting at an outward angle in a proximal direction away from the distal end of the first arm to engage the tissue or bone when inserted therein. The second fluke has similar features. This arrangement causes the first and second flukes to rotate in response to a pullout force on the bridge.

  • Publication number: 20210186677
    Abstract: A tendon repair implant for treatment of a complete or partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by arthroscopic means that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.

  • Patent number: 11020111
    Abstract: An improved method for attaching a sheet-like implant to tissue or bone with a fastener having a first and second arm, and a bridge extending therebetween. Each of the first and second arms include a trunk portion including a longitudinally displaced first and second projections extending in opposite directions within a plane defined by the trunk portions. The method includes forming first and second pilot holes in the tissue or bone using a trocar, receiving the first and second trunk portions within their respective pilot holes, and applying a pullout force on the bridge to create an in-plane torque on each trunk such that the resistance to pullout is increased.
