A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic means approach 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.

Tendon repair implant and method of arthroscopic implantation

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.

A guidewire for use with an implant delivery system in delivering a sheet-like implant is disclosed. The guidewire can include a distal tissue fixation member for releasable connection to a first location proximate a treatment site. An implant delivery system can include a distal guidewire port for receiving the proximal end of the guidewire. The implant delivery system is tracked over the guidewire to a selected position defined by the guidewire attachment. The tissue fixation member includes means for temporarily or reversibly fixing the distal end of the guidewire to tissue, such as bone. The means for affixing can include a K-wire, a screw, a pin or other fixation member.

A tissue marker assembly which can be useful with an implant delivery system for delivering a sheet-like implant is disclosed. The tissue marker assembly can include a delivery sleeve with a tissue marker slidably disposed within a lumen therethrough. A proximal handle can be coupled to the tissue marker and delivery sleeve, having a first part and a second part. The second part of the proximal handle can be releasably attached to the tissue marker proximal end so that the second part can be removed to allow the delivery sleeve to be removed proximally over the tissue marker after it is affixed to tissue. The distal portion of the marker can include a plurality of longitudinally extending arms when unconstrained project outward from the shaft to retain the marker's position in tissue.
