Publication number: 20060206136Abstract: A series of medical instruments can be made with the use of shape memory tube with a transformation temperature that is above or below the ambient temperature. In the first case, the material behaves with the shape memory effect and in the second case the behavior is superelastic. The wall of the tube has been provided with a plurality of slots in specific places, often near or at the distal end of the instrument, and in specific arrangements which allow local variations in diameter, shape, and/or length. These variations can either be caused by the memory effect during temperature change or by superelastic behavior during change of the mechanical influences on the memory metal by the surrounding material.Type: ApplicationFiled: May 2, 2006Publication date: September 14, 2006Applicant: Memory Medical Systems, Inc.Inventors: Rohit Sachdeva, Petrus Besselink

Patent number: 5791899Abstract: A bone anchoring assembly and method for attaching a body part to a patient's bone which includes a bone anchor that is implantable in bone having an opening leading to a cavity formed therein. A coupling member with at least one portion made of a shape memory material having a transformation temperature range is disclosed. The coupling member is movable through the opening and in and out of the cavity at temperatures below the transformation temperature range. With it in the cavity and at temperatures above the transformation temperature range, the coupling member is locked within the bone anchor. The coupling member is attachable to the body part.Type: GrantFiled: June 7, 1996Date of Patent: August 11, 1998Assignee: Memory Medical Systems, Inc.Inventors: Rohit Chaman Lal Sachdeva, Petrus Antonius Besselink

Patent number: 5607435Abstract: The present invention is an instrument (10) which includes a tubular section (12) having a wall (13) made of a material exhibiting superelastic characteristics and a delivery tube (14) having a bore (15) through which the tubular section (12) passes. The instrument (10) may be adapted for use in medical/dental and non-medical procedures. The superelastic character of the wall material is used in combination with the delivery tube (14) to alternately restrict the shape of the wall (13) and allow it to change to its unconstrained shape. Thus, the wall (13) can be sufficiently deformed to permit the tubular section (12) to pass in and out of and through the delivery tube (14) while at the same time enabling the tubular section (12) to have a shape when extended outside of the delivery tube (14) that is sufficiently bent or curved to be suitable for performing a desired function, for example a medical or dental procedure inside a patient's body.Type: GrantFiled: May 23, 1994Date of Patent: March 4, 1997Assignee: Memory Medical Systems, Inc.Inventors: Rohit C.

Patent number: 5507826Abstract: The present invention is a prosthesis (10) for replacing a body part which includes a first element (16) adapted to receive at least a portion of a second element (18) in an operative manner. The present prosthesis (10) also includes a variable locking ring (20) made of a shape memory material having a transformation temperature range ("TTR"). The locking ring (20) is used to allow insertion of the second element (18) into the first (16) at least at temperatures below the TTR and to lock the elements (16, 18) together at least at temperatures above the TTR. With it at a temperature below its TTR, the locking ring (20) is positioned between the two elements (16, 18). With it so positioned, the locking ring (20) is adapted to interlock the elements (16, 18) together at temperatures above its TTR by at least attempting to change its shape.Type: GrantFiled: April 11, 1994Date of Patent: April 16, 1996Assignee: Memory Medical Systems, Inc.Inventors: Petrus A. Besselink, Rohit C. L. Sachdeva
