Abstract:
PROBLEM TO BE SOLVED: To provide an implant assembly, not requiring long time for separating an implantable instrument from a pusher wire.SOLUTION: An implant assembly 14 includes: a slender pusher member 18; an implantable instrument (a vascular occlusion instrument) 22 fitted to the distal end part of the pusher member 18; and a joint 20 provided on the pusher member 18 and electrolytic-separable. When the separable joint 20 is separated, the implantable instrument 22 separates from the pusher member 18. The implant assembly 14 further includes: a return electrode such as a coil supported by the distal end part of the pusher member 18. Although the return electrode is close to the separable joint 20, it is electrically insulated therefrom, and the implant assembly 14 further includes: a terminal which has electrically communicating relationship with the separable joint 20 and is supported by the proximal end part of the pusher member 18.
Abstract:
A device for delivering an occlusive element includes an elongate sheath having a lumen therein. An elongate core member is disposed within the lumen and is formed from a proximal portion and distal portion connected via a joint. The distal portion of the elongate member includes a severable junction secured to the occlusive element. A marker coil is coaxially arranged around the distal portion of the elongate core member and is partially disposed inside the sheath lumen. A coil member is coaxially arranged around the distal portion of the elongate core member and coaxially arranged around at least a portion of the marker coil extending outside the lumen of the sheath. The coil member is secured at a distal end thereof to the distal portion of the elongate core member. The device resists axial compression while allowing for radial bending.

PROBLEM TO BE SOLVED: To provide methods and devices for inducing the formation of functional replacement nonarticular cartilage tissues and ligament tissues.SOLUTION: There are provided methods and devices for inducing the formation of functional replacement nonarticular cartilage tissues and ligament tissues. These methods and devices involve the use of osteogenic proteins, and are useful in repairing defects in the larynx, trachea, interarticular menisci intervertebral discs, ear, nose, ribs and other fibrocartilaginous tissues in a mammal.
Abstract:
PROBLEM TO BE SOLVED: To provide a highly concentrated aqueous protein preparations of proteins which are inherently insoluble under physiological conditions, including BMPs, as well as methods of treatment of skeletal and non-skeletal disorders, injuries and diseases using such preparations.SOLUTION: The invention provides the methods and reagents which can readily accomplish heretofore undescribed aqueous preparations of proteins which are highly concentrated, i.e. at last about two- to about five-fold, preferably about three-fold, more concentrated than those known in the art.
Abstract:
PROBLEM TO BE SOLVED: To provide a device, an implant and a method, that obviate the need for a mixture of osteogenic protein with matrix, and repair bone defect, cartilage defect and/or osteochondral defect.SOLUTION: Methods for inducing bone formation in a mammal sufficient to fill a defect defining a void, wherein osteogenic protein is provided alone or dispersed in a biocompatible non-rigid, amorphous carrier having no defined surfaces are provided. The methods and devices provide injectable formulations for filling critical size defects, as well as for accelerating the rate of and enhancing the quality of bone formation in non-critical size defects.
