摘要： 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.

摘要： A method of processing a Ni—Ti—Nb based alloy which contains from about 4 to about 14 atomic percent Nb and in which the ratio of atomic percent Ni to atomic percent Ti is from about 3.8 to 1.2, comprising working the alloy sufficient to impart a textured structure to the alloy, at a temperature below the recrystallisation temperature of the alloy. Preferably, the alloy is worked at least 10%, by a technique such as rolling or drawing, or another technique which produces a similar crystal structure. The alloy has increased stiffness compared with Ni—Ti binary alloys with superelastic properties.

摘要： 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. In this way, the delivery tube (14) enables the tubular section (12) to reach the site of the procedure through more narrow insertion paths, and in the case of medical/dental applications, with less trauma to the surrounding tissue along the insertion path. Because it can be inserted through more narrow pathways, the tubular section (12) can be delivered to more remote and harder to reach locations.

摘要： 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.
