A suture anchor is described which in one form may be easily fabricated from extruded material by angular cuts and bore holes which provide an offset pulling force to the suture. In an alternate and preferred embodiment the suture anchor is injection molded having an annular displaced corner and abutment wall which act to seat the suture anchor firmly within a bore hole. Novel application means are also disclosed which hold the suture anchor on a frangible shaft for insertion and upon completion of the insertion permit fracture of the frangible portion and removal of the instrument. In another form of the invention, the suture anchor comprises a substantially wedge-shaped body having a smaller distal end and a larger proximal end, means thereon for retaining a suture, and means thereon for releasable connection to an inserter shaft; a boundary surface and a plow surface of the body intersecting to form a biting edge at the proximal end of the body; and the boundary surface and an abutment surface of the body intersecting to form a cam surface at the proximal end of the body; and the biting edge being adapted to be in engagement with a first wall portion of a bore in a bone and the cam surface being adapted to be in engagement with a second wall portion of the bore opposed to the first wall portion; wherein tension on the inserter shaft is operable to move the cam portion along the bore second wall portion and rotate the body in the bore such that the biting edge bites into the bore first wall portion to lock the body in the bore.

A novel system and method for anchoring a suture or other cord-like element to a bone or other workpiece. The system comprises a drill for forming an undercut hole in a bone or other workpiece, an anchor for securing a suture or other cord-like element in the undercut hole in the bone or other workpiece, and an inserter for deploying the anchor in the undercut hole in the bone or other workpiece.

An applicator for deploying a fastener into tissue, the fastener including a head portion and a filament portion extending from the head portion, the applicator comprising an elongated hollow needle member having a pointed distal end portion, a slotted portion for releasably retaining the head of the shaped fastener, and a first connector portion; and a chuck comprising a second connector portion engageable with the first connector portion for interconnecting the needle member and the chuck, a push rod having a distal end portion adapted to move lengthwise in the needle member, and an actuator for moving the push rod in the needle member so as to eject the head portion of the fastener from the slotted portion of the needle member. A method for deploying the fastener in tissue is also disclosed.

A suture anchor device having an anchor member with outwardly extending wing members and an actuating wedge member. The suture anchor device is inserted into a bore hole in a bone as part of an orthopedic surgical procedure wherein soft tissue such as a tendon or ligament is attached to the surface of the bone. The wing members are spread outwardly by the wedge member to lock the suture anchor device in the bone. The suture anchor has similar utility in soft tissue applications.

A driving mechanism is provided as a means to clamp and implant surgical staples pneumatically. First, one pneumatic line propels a clamping piston to clamp the tissue and to propel a driving piston into position to be fired. Then a second pneumatic line causes the driving piston to propel a driver which implants staples into the tissue.

Pneumatically actuated surgical stapler head

A pneumatic connector for a surgical stapler is provided to enable interconnected parts of the stapler to be rotatable with respect to each other while maintaining the fluidic integrity of a plurality of pneumatic lines passing through the connector. One pneumatic line is connected to pass through the center of the pneumatic connector. The second pneumatic line is annularly rotatable around the first. The second line is rotatably completed and sealed by means of an annular mating passageway.

Pneumatic surgical stapler connectors

A surgical stapling instrument is provided which employs a highly pressurized gas as its source of energy. The highly pressurized gas is conducted to means for indicating the presence of the pressurized gas and to a pressure regulator. The pressure regulator controllably develops gas pressurized to a desired operating pressure. The pressure regulator supplies gas at a fixed or variable pressure to a tissue clamping mechanism and to the trigger mechanism of the instrument. In response to actuation of the trigger mechanism gas at the desired stapling pressure is supplied to a stapling mechanism. In a preferred embodiment, pressurized gas is maintained at the stapling mechanism until the trigger mechanism is reset for a subsequent stapling procedure.

Surgical stapler pressure regulator

A surgical stapling instrument is provided having safety and sequencing features to mandate proper operation of the instrument during surgical clamping and stapling of tissue. The instrument is powered by pressurized gas, and includes a manual control for supplying gas to a clamping mechanism in the stapler head and a trigger for actuating a stapling mechanism therein. The instrument prevents actuation of the trigger until the tissue has been clamped. The trigger may not be actuated to implant staples until a trigger safety has been actuated. Following actuation of the stapling mechanism, the instrument is either automatically reset to its initial condition, or may require manual control by the user to restore the clamping and stapling mechanisms to their initial conditions. The instrument affords correct sequencing of operation and prevents inadvertent stapling.
