Abstract: A catheter or the like is steerable through cavities within a body and aimable toward organs or tissue within the body. The catheter includes an elongated tubular member having a proximal end and a distal end for insertion into the body, a plurality of temperature-activated memory elements in the distal end of the tubular member, and a core for supporting the memory elements. Each memory element assumes a preset shape when heated to a predetermined temperature. A sleeve is provided to couple slidably each memory element to the core so that each memory element is permitted to slip in relation to the core and also to couple each memory element so that movement of one element results in movement of the other elements. Each memory element is moved to another shape when the memory element coupled thereto is heated to the predetermined temperature. A control system adjacent the proximal end of the tubular member allows an operator to control selectively the temperature of each temperature-activated element to deflect the distal end of the tubular member so as to either direct the course of the tubular member or to direct the distal end of the tubular member toward an organ or tissue within the body.

Abstract: A method for plugging the ends of defective tubes in shell and tube heat exchangers is described. The plug utilized in the method is fabricated from a metallic alloy having a mechanical memory characteristic whereby it can be physically deformed into a reduced diameter for insertion into the tube end and thereafter induced to assume its original diameter to thus secure the plug within the tube.

Abstract: The invention relates to multi-component shape memory threads, fibers, tubes, or tapes, which includes at least two shape-memory polymeric (SMP-N) components. Each of the at least two SMP-N components is of at least 1% of the total weight, and N is a positive integer starting from 1, and the SMP-N components have a selectively engineered shape recovery temperature (Tr) between approximately 0° C. to 130° C. Also, when TrN and TrN+1 are higher than room temperature, the threads, fibers, tubes, or tapes are configured to assume a substantially helical configuration upon heating to above TrN and lower than TrN+1 by a stimulus when an elongation of the threads, fibers, tubes, or tapes is approximately 30% to approximately 300%, and having a coil diameter from 0.5 to 10 mm and a number of the turns per cm from 5 to 30.

Abstract: Shape memory tissue engagement elements (15) are created using shape memory alloys or shape memory (SM) composite sheets (33, 36) with one or more SM material sheets (20, 32). Arrays of the tissue engagement elements may then be inserted or molded into flexible base materials forming pads for tissue engagement. In certain embodiments, the composite sheets incorporate two SM material layers (20, 32) having differing transition temperatures to allow activation of one layer for tissue engagement and activation of the second layer for tissue release. In exemplary embodiments, insertion of interconnected tissue engagement elements (46) into a base layer (19) with slots (48) provides a completed pad array. In alternative exemplary embodiments, vacuum forming of composite sheets (51) with cutting of corrugated sides (53) to form tissue engagement elements allow production of complete arrays of tissue engagement elements. Overmolding the arrays with a flexible base material (19) provides a completed pad.
