  • Patent number: 10426464
    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: 20190274814
    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.

  • Publication number: 20190029804
    Abstract: Apparatus and methods for forming pilot holes in bone and deploying a staple therein for fixing a sheet-like implant to the bone. A pilot hole forming trocar assembly including a trocar and a position retention sleeve can be included. The trocar can be releasably coupled to the position retention sleeve and slide in keyed arrangement within the sleeve when uncoupled. The trocar can include a distal portion having a retractable blade and a pair of pilot hole forming spikes extending distally from the trocar shaft. Once the pilot holes are formed, the position retention sleeve maintains the position relative to the pilot holes while the trocar is removed and a staple delivery device can be inserted in the lumen of the position retention sleeve to deploy a staple in the pilot holes.

  • Publication number: 20190029802
    Abstract: 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 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.

  • Publication number: 20190015145
    Abstract: Implant delivery systems for delivering sheet-like implants include a delivery shaft, an implant expander, a sheath, and a sheet-like implant. In some embodiments, the delivery shaft has a proximal end and a distal end. The implant expander is mounted to the distal end of the delivery shaft. The implant expander includes a central portion and a plurality of leg portions radiating from the central portion. The implant expander is evertable between an unstressed configuration in which a distal surface of the implant expander defines a concave surface, and a first compact configuration in which the distal surface of the implant expander defines a convex surface. The implant expander has a first lateral extent when the implant expander is free to assume the unstressed configuration. The sheath defines a lumen having a lumen diameter. At least a portion of the delivery shaft is slidably disposed in the lumen.

  • Publication number: 20180369017
    Abstract: An illustrative method for reducing intraocular pressure in a patient may comprise deploying an ocular implant adapted to reside at least partially in a portion of Schlemm's canal of an eye and administering a therapeutic agent comprising a Rho kinase (ROCK) inhibitor to the patient. The ocular implant may be configured to lower the intraocular pressure from an initial to a second pressure within a first range and the therapeutic agent may lower an intraocular pressure to a third pressure within a second range, the third pressure lower than the second pressure.

  • Publication number: 20180256162
    Abstract: A device for attaching a sheet-like implant to a target tissue. The device includes a fastener push rod including a first portion, a second portion and a force limiting mechanism operably coupled between the first portion and the second portion. A fastener is carried by the second portion of the fastener push rod. The force limiting mechanism transmits longitudinal movement of the first portion to the second portion while the forces applied to the fastener by the fastener push rod are less than a predetermined value such that longitudinal movement of the first portion of the fastener push rod causes substantially equivalent longitudinal movement of the second portion. The force limiting mechanism allows relative longitudinal motion between the first and second portions while the forces applied to the fastener are equal to or greater than the predetermined value such that the application of undue forces to the fastener is prevented.

  • Publication number: 20180185024
    Abstract: Devices for attaching a sheet-like implant to a target tissue include a sheath and a staple push rod. The sheath has a distal end configured to be pressed against the target tissue. The staple push rod is disposed within at least a portion of the sheath and is slidable relative thereto. The staple push rod includes a pair of stakes. Each stake is dimensioned to abut a surface of a staple to apply pushing forces thereto. The stakes are biased to assume a bow-like shape such that an intermediate portion of a staple extends tautly between the first stake and the second stake when the stakes are extending beyond the distal end of the tubular member. Methods for attaching a sheet-like implant to a target tissue are also disclosed.
