Abstract: A method for immediately placing a non-occlusive and non-functional temporary dental implant prosthesis in the jawbone of a human patient with the prosthesis having a size and shape of a natural human tooth.

Abstract: An improved, non-resorbable annuloplasty ring that will provide support for the valve annulus while also promoting healing and/or regeneration of the annulus tissue is disclosed. Healing and/or regeneration of valvular tissue is promoted using a growth factor mixture that has been shown to be capable of promoting growth of a wide range of tissues, including heart valve tissue, and which promotes tissue growth based upon the local tissue environment (i.e., specific cell recruitment and proliferation). Thus, an annuloplasty ring that provides an actual healing response in addition to mechanical support to a dilated heart valve annulus is provided.

Abstract: A radio frequency ablation apparatus having an application wand which is articulating and self-locking in a selected configuration. The wand has a handle having a thumb wheel apparatus. A threaded bore extends coaxially through the thumb wheel. A threaded tube received in the threaded bore translates a wire which extends to the distal end of the wand. At the distal end of the wand, the wire passes over a bendable section in the wand. Pushing or pulling the wire bends the distal tip through a range of angles on both sides of a neutral linear position. The distal tip remains self-locked in a selected position when the thumb screw is not turned.
