Filed:

Nov 14, 2001

Appl. No.:

09/994088

Inventors:

Jeffrey L. Trudeau - Marquette MI, US
Thomas S. Kilpela - Marquette MI, US
Brian P. Janowski - Marquette MI, US

Assignee:

Pioneer Surgical Technology, Inc. - Marquette MI

International Classification:

A61B 17/56
A61B 17/58

US Classification:

606103, 606 74

Abstract:

Disclosed is a clamp for securing cables or other elongate members used in surgical fastening procedures. The clamp advantageously applies a clamping force to the cable without direct contact with the cable, thereby reducing abrasion and shear forces applied to the cable. The disclosed clamps have a saddle member, platen or both that are movably mounted with respect to the housing and a lever, in cooperation with a cam surface, that allows the saddle member, platen or both to selectively clamp the cable. The lever may have several locking positions to provide optimum clamping force to different sized cables.

Assignee:

EC Sander, L.L.C. - Traunik MI

International Classification:

B24B 27/08
B24D 11/00

US Classification:

451344, 451523, 451526

Abstract:

A drywall sander includes a replaceable sanding pad having a layer of resilient material, and an abrasive surface. The sanding pad includes one or more edge portions that project beyond the edges of a sander head. The edges of the sanding pad can be deformed during use when the sander is used in a corner or the like to thereby prevent scuffing or other damage to adjacent orthogonal surfaces.

Inventors:

Jeffrey L. Trudeau - Marquette MI, US

Assignee:

Pioneer Surgical Technology - Marquette MI

International Classification:

A61B 17/58
A61B 17/60
A61F 2/00

US Classification:

606 99

Abstract:

An insertion instrument for inserting an implant in an intervertebral space is provided. The instrument includes an elongate shaft having proximate and distal ends with a longitudinal axis therebetween. On the distal end of the elongate shaft is a gripping device capable of shifting from a holding configuration for securing a portion of the implant relative the distal end and a releasing configuration to permit removal of the implant portion from the elongate shaft. The instrument includes a handle configured to be held with a generally neutral wrist position to permit comfortable use of the instrument. The instrument also includes an actuating mechanism coupled between the gripping device and the handle that is operable to configure the gripping device in the holding configuration upon an initial actuation thereof and the releasing configuration upon a subsequent actuation thereof.

International Classification:

A61F 2/44

US Classification:

623 1714, 623 1713

Abstract:

An implant retention device is provided to assist in restraining movement of a nuclear implant and to assist in preventing expulsion of the nuclear implant through an incision portal or defect in the annular wall. In one form, the implant retention device comprises an expulsion prevention member associated with the nuclear implant and is configured to transition between an unexpanded position and an expanded position. In another form, a method for restraining a nuclear implant includes cutting an opening in the annulus, shifting an implant retention device into an unexpanded position, inserting the implant retention device through the opening, and shifting the retention device to an expanded position.

US Classification:

623 1716, 606 99

Abstract:

A system for replacing a natural nuclear disc in an intervertebral space has a spinal device configured for placement in the intervertebral space. An insertion tool is configured for holding the spinal device while the spinal device is inserted into the intervertebral space. A gripping member of the insertion tool has an end for adjustably holding the spinal device within the intervertebral space. A steering actuator of the insertion tool is operably connected to the spinal device and configured for pivoting the adjustably held spinal device within the intervertebral space while the steering actuator is controlled remotely from the intervertebral space.

International Classification:

A61F 2/44

US Classification:

623 1711

Abstract:

An implant retention device is provided to assist in restraining movement of a nuclear implant and to assist in preventing expulsion of the nuclear implant through an incision portal or defect in the annular wall. In general, the implant retention device blocks or obstructs at least a portion of an opening in the annular wall, thereby keeping the implant from exiting the nuclear space through the annular opening. In one form, the implant retention device comprises an expulsion prevention member positioned adjacent the nuclear implant and configured to transition between a compressed position and an expanded position. In another form, the implant retention device may comprise a mounting portion to be positioned adjacent one of the vertebral bodies, a blocking portion for at least partially obstructing the annular opening, and an end projection at a terminal end of the blocking portion to resist expulsion of the implant through the annular opening. In yet another form, the implant retention device may include an elongate blocking member having annulus connector portions extending from each side of the blocking member for engaging with an annular wall.

Abstract:

A motion preserving implant having first and second bearing members and a biasing member disposed therebetween operable to provide resistance to the translation of the bodies with respect to one another. An intervertebral implant having first and second bearing members, a translatable member, a resilient connection between the translatable member and one of the bearing members to allow for relative motion therebetween and bearing surfaces of the translatable member and the other bearing member to allow complex, natural motion between the bearing members. A spinal implant having upper and lower bodies and an articulation surface that allows for polyaxial articulation and translation through a concave articulation surface having a first radius of curvature and a second radius of curvature in at least one plane, and a convex articulation surface having the first radius of curvature in the same plane.
