First Claim
Patent Images
1. A process comprising the steps of:
- a) providing a precursor for an implantable medical device, at least a portion of the precursor made of a shape memory material, the shape memory material having a receptacle for receiving a marker therein, the shape memory material having an austenitic and a martensitic phase, the receptacle having a first shape when there is no marker therein and the shape memory material is in the martensitic phase;
b) enlarging the receptacle while the shape memory material is in the martensitic phase;
c) subsequently inserting a marker in the receptacle while the shape memory material is in the martensitic phase, the receptacle having a second shape after the marker is inserted into the receptacle, the second shape the same as the first shape; and
thereafterd) transforming the precursor to the austenitic phase.

19. A process comprising the steps of:
-
a) providing a precursor for an implantable medical device, at least a portion of the device made of a shape memory material, the shape memory material having a receptacle for receiving a marker therein, the shape memory material having at least a first phase and a second phase, the receptacle having a first shape in the first phase, the receptacle having a second shape in the second phase, the first shape the same as the second shape; b) causing the shape memory material to transition from the first phase to the second phase; c) enlarging the receptacle while the shape memory material is in the second phase; d) subsequently inserting a marker in the receptacle while the shape memory material is in the second phase; and
thereaftere) transforming the precursor to the first phase. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
