Patent number: 5916216Abstract: A graft fixation device for positioning and anchoring a bone graft within a bony channel. The fixation device generally comprises a rigid cylindrical member extending about a central axis, the member including an eccentric bore extending about an axis which is substantially parallel to, and radially offset from, the central axis. The fixation device is adapted to receive a rotational force applied to it. Rotation of the fixation device causes a bone plug installed and secured therein to move laterally within a bony channel, thus bringing the bone plug in contact with a portion of the channel wall. Preferably, the cancellous bone regions of the bone plugs and the bony channel are brought into abutting contact for optimum bone ingrowth opportunity and maximum graft fixation strength.Type: GrantFiled: November 4, 1996Date of Patent: June 29, 1999Assignee: Wright Medical Technology, Inc.Inventors: Allen H. DeSatnick, Herbert Marcus

Patent number: 5899920Abstract: A self-threading suture anchor assembly and kit includes a suture anchor having an anchor portion at one end and a drive portion with an eyelet at an opposite end, and an elongated suture threading loop with an elongated, substantially rigid gripping member attached thereto. The threading loop is collapsible, yet it maintains a loop shape. The elongated gripping member acts as a wand for manipulation of the loop. Both the threading loop and the elongated gripping member are adapted to be encased in a removable elongated sheath which extends beyond the ends of the loop and gripping member. The assembly is inserted into a cannulated shaft of a rotatable driver which includes a bone-cutting drive bit adapted for gripping the suture anchor at its drive end and for cutting into bone. The distal portion of the elongated sheath extends through a port in the shaft and is frictionally engageable with the shaft by means of an annular retaining element slidably disposed on the shaft.Type: GrantFiled: February 11, 1997Date of Patent: May 4, 1999Assignee: Wright Medical Technology, Inc.Inventors: Allen H.

Patent number: 4433687Abstract: A microsurgical scissors uses a rotary cutting action and biased blades that intersect in a travelling point of contact. One blade is situated on the end of a tubular shaft and a second blade is on a rod that is rotatable within the shaft. The blades are angled so their cutting edges intersect each other. To assure a precise shearing relationship, the rod is biased rearward in order to bear the cutting edge of the rod blade against the cutting edge of the shaft blade. An actuating mechanism in the handle translates linear finger motion into rotary motion of the rod. The blades cut cleanly and surely without imparting undue tissue trauma.Type: GrantFiled: March 26, 1982Date of Patent: February 28, 1984Assignee: Acufex Microsurgical, Inc.Inventors: Roger M. Burke, Allen H. DeSatnick, George P. Honkanen
