Filed:

Nov 30, 2005

Appl. No.:

11/292333

Inventors:

Jason Ian Partin - Encinitas CA, US
Robert J. Ball - San Marcos CA, US
Ian A. Trail - Manchester, GB

Assignee:

Integra Lifesciences Corporation - Plainsboro NJ

International Classification:

A61B 17/80

US Classification:

606289

Abstract:

Systems and methods for bone fixation are disclosed. A fixation system can have a planar fixation device and a laterally-fixed fixation apparatus. The planar fixation device can have a planar surface and at least one opening having side walls defining an at least generally cylindrical shape. The laterally-fixed fixation apparatus can have an at least generally cylindrical shaped head portion having outer wall sections at least partially surrounding a central hollow area. The head portion can have an inner bottom surface. An expander hub is provided in the fixation apparatus for positioning at least partially within the central hollow area of the head portion and can be seated at least partially on the inner bottom surface of the head portion. The expander hub is rotatable to force the outer wall sections of the head portion outwardly for engaging and locking the fixation apparatus in place in the opening. The fixation apparatus is further adapted for rotation about a longitudinal axis of the fixation apparatus without lateral toggle movement relative to the planar surface of the planar fixation device.

Appl. No.:

11/697655

Inventors:

Jason Ian Partin - Encinitas CA, US

International Classification:

A61B 17/86

US Classification:

606320, 606301, 606314, 606315

Abstract:

A bone fixation device includes one or more springs and one or more spacers disposed between two orthopedic structures. The orthopedic structures may comprise screws, rods, plates, or any other orthopedic devices configured to engage bone. The spacer may be absorbable or removable, and may serve to constrain the spring in a compressed or stretched state so that, upon absorption or removal of the spacer, the spring may apply tension or compression to surrounding bone. The device may thereby facilitate healing or bone or remodeling of soft tissues.

International Classification:

US Classification:

623021110, 623023500

Abstract:

Resorbable medical implants and related methods are disclosed for placement against bone and/or for filling a void such as a void between bones. The resorbable medical implants can be structured and configured as desired, for example, to conform to surfaces of adjacent bones and/or to conform to a desired bone shape for replacement otherwise. Short-term fixation of the resorbable medical implants can advantageously assist in promoting and allowing growth of new bone tissue into the implant as the implant gradually resorbs. The implant can comprise a material that is porous with microscopic and non-microscopic pores. In one aspect, the resorbable implant can be shaped and used as a trapezium bone replacement.
