Abstract:
A catheter for positioning at least one electrode at a selected biological site, said catheter comprising:a sheath having a distal end carrying the at least one electrode;a stylet disposed within the sheath and attached to the distal end of the sheath, the stylet having a distal end region having a preformed shape with a radius of curvature, the stylet formed of a shape-retentive and resilient material such that the stylet distal end region changes shape upon the application of force and upon the removal of force, returns to the preformed shape, the stylet disposed in the sheath such that the stylet distal end region is located in the distal end region of the sheath and causes the sheath to assume the preformed shape; anda tendon housed within the sheath and attached to the distal end of the sheath such that axial displacement of the tendon changes the radius of curvature of the stylet distal end region and the sheath distal end region.
