Abstract
A process comprising the steps of 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; enlarging the receptacle while the shape memory material is in the martensitic phase; inserting a marker in the receptacle while the shape memory material is in the martensitic phase; and thereafter transforming the precursor to the austenitic phase.

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 thereafter
- d) transforming the precursor to the austenitic phase.
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 thereafter
- e) transforming the precursor to the first phase.
