Publication number: 20130190820Abstract: Devices and methods for spinous process implants with two plates that are connected together by a post, with each plate configured to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. The second of the two plates includes a bore that receives the post, and that plate is movable along the length of the post to accommodate different anatomies, and selectively lockable in position. The post includes external gear teeth. A tool with a drive gear is used to releasably gearingly engage the gear teeth of the post and drive the second plate toward the first plate. When the plates are in their desired locations, the second plate is locked in position and the surgical tool may be removed.Type: ApplicationFiled: January 25, 2012Publication date: July 25, 2013Applicant: Warsaw Orthopedic, Inc.Inventors: Daniel E.

Publication number: 20110137315Abstract: A cutting instrument and method of use for preparing an osteochondral plug for implantation into a bone defect site. The instrument includes a dual function cutting block, a base holder, a rod mechanism and a trimming mechanism. The cutting block has a bore sized to receive the plug, at least one trimming channel and a transverse paring slot. The cutting block functions to hold the plug within the bore to allow for length and cross-sectional sizing. The base holder is constructed to fix the cutting block in a first orientation that allows the rod mechanism to position the plug within the cutting block for accurate length sizing. The base holder is also constructed to fix the cutting block in a second orientation which aligns the cutting block with the trimming mechanism so that an angled blade may engage the trimming channel and cut at least two sides of the plug.Type: ApplicationFiled: February 15, 2011Publication date: June 9, 2011Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Carlos E. Gil, Jeetendra S. Bharadwaj

Publication number: 20110066156Abstract: A surgical tool for removing a portion of an implant is provided that includes a housing, a motor contained within the housing and coupled to the housing, and an output shaft having a distal end and a proximal end opposite the distal end, wherein the proximal end is coupled to the motor and the distal end has an opening configured to rotateably engage an implant. The surgical tool further includes a counter-torque sleeve extending around the output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the housing and the distal end is configured to couple to the implant relative to the counter-torque sleeve. Upon a rotational force to the implant, the forces transmitted by the output shaft and the counter-torque sleeve are balanced by the coupling of the output shaft and counter-torque sleeve through the housing.Type: ApplicationFiled: September 14, 2009Publication date: March 17, 2011Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Thomas V.

Patent number: 7887546Abstract: A surgical instrument and method are provided for positioning an osteochondral plug within a bone defect site. The instrument includes an elongate shaft, a ribbon, an elongate sleeve and a locking mechanism. The shaft has proximal and distal ends, with the distal end being shaped to contact the osteochondral plug. The ribbon extends along two sides of the shaft and around the distal end, forming a loop that is used to secure the osteochondral plug to the distal end. The sleeve is movably mounted to the shaft for reciprocating relative thereto between retracted and extended positions. The sleeve includes a slot that allows for visualization and cutting of the ribbon. The locking mechanism locks the ribbon in place and thereby controls the size and tension of the loop that surrounds the osteochondral plug, securing it to the distal end of the shaft.Type: GrantFiled: June 4, 2010Date of Patent: February 15, 2011Inventors: Carols E. Gil, Jeetendra S. Bharadwaj, Michael A. Dupree
