Patent number: 7163562Abstract: 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.Type: GrantFiled: January 29, 2002Date of Patent: January 16, 2007Assignee: Ethicon, Inc.Inventors: Arindam Datta, Shawn Thayer Huxel, Dennis D. Jamiolkowski, Yufu Li

Patent number: 7032599Abstract: 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.Type: GrantFiled: May 15, 2003Date of Patent: April 25, 2006Assignee: Mitek Surgical Products Div. of Ethicon, Inc.Inventors: Thomas C.

Patent number: 6997305Abstract: 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.Type: GrantFiled: August 20, 2003Date of Patent: February 14, 2006Assignee: Ethicon, Inc.Inventors: David D.
