Patent number: 7955449Abstract: A process for inducing a two-way shape memory effect in a device forward of a shape memory alloy and a device made by the process are disclosed. The two-way memory effect occurs in the device in a temperature range of between about 5° C. to 25° C. wherein the training process is based on B2R phrase transformations. An R-phase formation or reorientation takes place in the device under stress whereupon the R-phase transforms into stress induced martenite. The device is subjected to thermocycling.Type: GrantFiled: July 17, 2008Date of Patent: June 7, 2011Assignee: Intek Technology, L.L.C.Inventors: Sergey Dmitrievich Prokoshkin, Irina Yurievna Khmelevskaya, Elena Prokopievna Ryklina

Publication number: 20100087913Abstract: A stent formed of a metallic material having a two-way memory adapted to be retrieved or repositioned after delivery includes an elongated tubular body and at least one crown connected to a respective longitudinal end of said body, the crown including a plurality of unconnected leaves, each leaf having a longitudinally extending frame connected at one end to said end of said body. A method of manufacturing the stent to that the crown has a greater two-way memory effect than the body is disclosed.Type: ApplicationFiled: October 5, 2009Publication date: April 8, 2010Applicant: InTek Technology L.L.C.Inventors: Dmitry J. Rabkin, Eval Morag, Ophir Perelson
