  • Patent number: 7163562
    Abstract: A biodegradable stent for implantation into a lumen in a human body. The stent in one embodiment is made from a biodegradable fiber having an inner core and an outer layer. The outer layer is a blend of two polymer components. The inner core has a first degradation rate, and the outer layer has a second degradation rate. The second degradation rate is slower than the first degradation rate. The fiber softens in vivo such that the stent is readily passed from the lumen as a softened fragment or filament after a pre-determined period of time through normal flow of body fluids passing through the lumen.

  • Patent number: 7032599
    Abstract: A method of reconstructing a ruptured anterior cruciate ligament in a human knee. Femoral and tibial tunnels are drilled into the femur and tibia. A transverse tunnel is drilled into the femur to intersect the femoral tunnel. A replacement graft is formed into a loop and moved into the femoral and tibial tunnels using a surgical needle and suture. A flexible filamentary member is simultaneously moved along with the loop into the femoral and transverse tunnels. The filamentary member is used as a guide wire in the transverse tunnel to insert a cannulated cross-pin to secure a top of the looped graft in the femoral tunnel.

  • Patent number: 6997305
    Abstract: A device for singulating surgical needles from a bulk supply of needles includes a vibratory bowl for receiving the supply of needles. The bowl has a floor to receive the needles, a track extending from the floor to a needle discharge point and a selectively vibrating motor to vibrate the surgical needles into a single file along the track. A discharge device has first and second needle receiving pockets, and positions the first and the second needle receiving pockets below the needle discharge point. A controller selectively vibrates the vibratory bowl and selectively positions the first and second needle pockets below the needle discharge point, the controller singulating individual needles from the single file of needles into the first and second needle receiving pockets. A discharger discharges the singulated needles in a spaced relationship on a conveyor for subsequent imaging at an inspection station.

  • Patent number: 6932834
    Abstract: A suture anchor for affixing soft tissue to bone. The anchor has a hollow outer member, and an actuation member slidably mounted within the outer member. The actuation member has at least two engagement members that are pivotally mounted to the actuation member. Proximal movement of the actuation member with respect to the outer member causes the engagement members to move outward to a deployed position, wherein the engagement members are deployed in bone. A surgical suture is mounted to the anchor.

  • Patent number: 6804937
    Abstract: A machine and process for packaging armed sutures into tray packages. The machine has a frame with a rotatable indexing disc member mounted to the top of the frame. A plurality of tool nests are rotatably mounted to the top of the indexing disc. Tray packages mounted in the toll nests are rotated to wind sutures into a suture channel in the packages. A stylus having a front nose member and a rear heel member guides suture into the suture channel. Channel winding pins in the winding tooling provide for an arranged wind of suture in a suture channel of the tray packages. The machine has an in-line printer and a punching machine for printing and punching paper covers from strips of stock material, which are then mounted to the tray packages.

  • Patent number: 6494908
    Abstract: A removable stent for implantation into a lumen in a human body. The stent is made from a soft, flexible fiber having an outer surface. An outer bioabsorbable/degradable coating is applied to the outer surface of the filament causing it to become rigid. The coating softens in vivo through absorption and/or degradation such that the stent is readily passed or removed from the lumen as a softened filament after a pre-determined period of time through normal flow of body fluids passing through the lumen or by manual removal.
