  • Publication number: 20110000950
    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.

  • Publication number: 20100312275
    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: 20100312250
    Abstract: A device for attaching a sheet-like implant to a target tissue includes a pilot member and a staple push rod. In some embodiments, the pilot member has a distal end and at least a pair of prongs extending from the distal end. The prongs are configured to form pilot holes when the distal end of the pilot member is pressed against the target tissue. The staple push rod is disposed within at least a portion of the pilot member and slidable relative thereto. The staple push rod includes at least a pair of stakes. Each stake is dimensioned to engage a surface of a staple to apply pushing forces thereto. Each stake is positioned relative to a prong along an inner surface of the pilot member so that the stakes advance into the pilot holes when the stakes are moved in a distal direction.

  • Publication number: 20100241227
    Abstract: A tendon repair implant delivery system and methods incorporating a guide member having a temporary fixation member on or adjacent to the distal end. The point of fixation defines a target site for placement of the tendon repair implant which is subsequently affixed to the tendon.

  • Publication number: 20090132040
    Abstract: A method of inserting an ocular implant into a patient's eye, the ocular implant being mounted on a carrier, the method comprising: inserting a cannula into an anterior chamber of the eye; moving a distal exit port of the cannula into communication with Schlemm's canal; and advancing the ocular implant and carrier through an exit port of the cannula into Schlemm's canal. The invention also provides an ocular implant and delivery system comprising: a cannula comprising a distal exit port adapted to be inserted into a Schlemm's canal portion of an eye; an ocular implant; a carrier disposed within the implant and movable with the implant within the cannula; and a proximal control adapted to be operated from exterior to an eye to move at least one of the carrier and the implant when the distal exit port of the cannula is within the eye.

  • Publication number: 20070100441
    Abstract: A mitral valve annuloplasty prosthesis (ring or C) has a generally saddle shape, i.e., portions of the prosthesis that are or will be adjacent the anterior and posterior commissures of the valve are relatively low as compared to at least some other portions of the prosthesis that are or will be between the commissures. However, the saddle shape is asymmetrical, in that the portion that is or will be adjacent the posterior commissure is lower than the portion that is or will be adjacent the anterior commissure.
