A suture securing device includes an outer member with a suture receiving passage and an inner member configured for progressive insertion within the suture receiving passage and engagement with the outer member in any one of a plurality of locked positions to secure a suture between the inner member and the outer member. The suture receiving passage includes a threaded portion and the inner member includes a ridge for progressive engagement with threads of the threaded portion. A suture securing cartridge includes a sleeve having an axial bore with the outer member disposed in the bore at a distal end of the sleeve, the inner member disposed in the bore proximally of the outer member, and a carrier which engages the inner member to align the inner member with the suture receiving passage.

A handle assembly for a drive tool includes a plunger actuator configured to move a plunger of the drive tool between a retracted position and an extended position, an outer tube actuator configured to move an outer tube of the drive tool between a retracted position and an extended position, and a coupler configured to move the outer tube from its extended position to its retracted position in response to movement of the plunger from its extended position to its retracted position. The drive tool delivers a suture securing device to a surgical site. When the plunger actuator moves the plunger to its extended position, a second member of the device is secured to a first member of the device. When the plunger actuator moves the plunger to a second, further extended position, the plunger deploys the secured first and second members from the drive tool.

An instrument for extracting an orthopedic prosthesis having an elongated shank implanted in bone and defining a first longitudinal axis and a tapered stem projecting from the shank and defining a second longitudinal axis oriented at an oblique angle relative to the first axis includes a lower jaw defining a first opening for receiving the tapered stem, an upper jaw pivotally connected to the lower jaw and defining a second opening in opposed relation to the first opening, and a mechanism for pivoting the upper and lower jaws apart so that, when the tapered stem is received in the first and second openings, at least one of the first and second openings is caused to tilt relative to the second longitudinal axis such that diagonally opposed inside surfaces of the tilted opening contact the tapered stem of the prosthesis at longitudinally spaced locations to secure the instrument to the tapered stem so that an extraction tool can be attached to the instrument and used to exert an extraction force substantially parallel to the first longitudinal axis of the prosthesis. One of a plurality of inserts having differently sized openings is preferably telescopically received in the second jaw opening to accomodate various degrees of taper, and the insert is preferably held in place within the jaw opening by a retainer such as a shoulder screw threaded into the top surface of the upper jaw so that, when the jaws are pivoted apart, inner surfaces of the insert opening will contact the tapered stem to secure the instrument to the prosthesis.

An interference bone fixation screw fabricated from bioabsorbable material includes a body having a proximal end, a distal end and a screw thread disposed therealong from the proximal end to the distal end. A drive recess is formed in the body to extend longitudinally from the proximal end toward the distal end for receiving a rotatable driver. The drive recess defines a plurality of radial force receiving surfaces for receiving concentric forces from the driver applied perpendicularly to the force receiving surfaces.

A cannulated bioabsorbable tack has annular ribs configured to enhance fixation to tissue, such as bone, and is particularly effective for attaching soft tissue to bone, such as ligaments or muscles in the shoulder. Apparatus and method for displaying the tack facilitate arthroscopic surgical procedures for attaching or joining tissue.

Bioabsorbable tack for joining bodily tissue

A cannulated bioabsorbable tack has annular ribs configured to enhance fixation to invivo tissue and is particularly effective for attaching soft tissue to bone, such as ligaments or muscles. Apparatus including a trocar wire, an inserter and an impactor facilitates arthroscopic surgical procedures for inserting the tack invivo to attach or join the tissue.

A guided bone screw includes proximal and distal sections threaded with different pitches in the same direction and spaced by an unthreaded intermediate section having a shorter length than the distal section with a diameter substantially equal to the major diameter of the distal section. The intermediate section diameter is greater than the minor diameter and smaller than the major diameter of the proximal section thread. The threads of both the distal and proximal sections are self-tapping. A guide bore for a guide wire extends the entire length of the screw. Two drive recesses are disposed in the proximal screw end on opposite sides of the guide bore for engagement by a two-pin screwdriver. The unthreaded intermediate section radially fills the bone bore in which it is implanted to provide lateral stability for the bone screw.

A soft tissue washer for use with a cancellous screw for attaching soft tissue, such as ligaments, to bone has posts disposed on a distal face of a washer body to limit penetration of sharp pins extending from the distal face into soft tissue, an annular recess disposed is the distal face to receive and clamp soft tissue, recess portions deeper than the annular recess disposed in the distal face to relieve compression of soft tissue, a dished recess in a proximal face of the washer body to entirely receive the head of the cancellous screw such that the head does not protrude from the washer and suture retention passages extending from the dished recess to a lateral rim of the washer for receiving sutures.
