Abstract: With the use of shape memory elements a series of devices can be made which change shape at small changes of the environmental temperature. The devices may be composed of a shape memory element and a bias element, in such a way that the thermal hysteresis of the device becomes lower than the intrinsic thermal hysteresis or the shape memory element. The devices may be used in jewelry that is adapted to change shape or configuration when subjected to temperatures in the region of the body of a wearer.

Abstract: A releasable fastener system comprises a loop portion and a hook portion. The loop portion includes a support and a loop material disposed on one side thereof. The hook portion includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof, wherein the plurality of hook elements comprises a fiber and a shape memory alloy coating deposited onto the fiber, and wherein the fiber and the shape memory alloy coating comprises a non-axisymmetric coating or deposition of the shape memory alloy about a portion of the fiber. When the hook portion and loop portion are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. Introducing a thermal activation signal to the plurality of hook elements causes a change in shape orientation, flexural modulus property, or a combination thereof that is effectively reduces the shear and/or pull off forces in the releasable engagement. In this manner, disengagement of the releasable fastener system provides separation of the hook portion from the loop portion under controlled conditions.

Abstract: Apparatus and methods are provided for treating female urinary incontinence by applying a form of energy to tissue in the vicinity of the urethra and/or bladder outlet to change tissue compliance without substantially narrowing the urethral and/or bladder outlet lumen. The apparatus comprises an elongated shaft having a means for treating urethral tissue and an expandable member deployable distal of the means for treating. The expandable member is configured to be anchored against the bladder outlet to dispose the means for treating at a desired treatment site in the urethra using only tactile feedback. The means for treating may include a needleless RF electrode, an ultrasound transducer, or a cryogenic probe configured to be advanced through a hollow needle, each of which are designed to reduce or eliminate symptoms associated with urinary incontinence.
