1. A medical device, comprising:
- an elongate body comprising a proximal end, a distal end, an outer sheath, and a conductor extending within the sheath and between the proximal and distal ends of the body;
the sheath having an overall length and including a retaining segment extending along a length, which is less than the overall length;
the retaining segment forming a fixed portion of an outer surface of the sheath and including a plurality of projections extending from the portion of the outer surface;
wherein the plurality of projections are adapted to interfere with a wall of a generally tubular vessel to retain the body within the vessel; and
the plurality of projections lie approximately parallel with the portion of the outer surface when the length is approximately straight and protrude laterally from the portion of the outer surface when the length is bent.

25. A medical device, comprising:
-
an elongate body comprising a proximal end, a distal end and a sheath having a length extending between the proximal and distal ends; and a collar positioned about the body and having a length less than the sheath length, the collar forming a fixed portion of an outer surface of the body and including a plurality of projections extending from the portion of the outer surface; wherein the plurality of projections are adapted to interfere with a wall of a generally tubular vessel to retain the body within the vessel; and the plurality of projections lie approximately parallel with the portion of the outer surface when the length of the collar is approximately straight, and protrude laterally from the outer surface when the length of the collar is bent. - View Dependent Claims (26, 27, 28)

29. A medical device, comprising:
-
an elongate body; and a retaining segment extending along a length of the body and forming a fixed portion of an outer surface of the body; the retaining segment comprising a first material and a plurality of projections, each of the plurality of projections being formed from a second material separate from the first material, and the projections extending from the fixed portion of the outer surface; wherein the projections are embedded in the first material of the retaining segment; the second material forming each projection is selected from the group consisting of metal particles, hard plastic particles, carbon particles, polymer fibers, and carbon fibers; and the projections are adapted to interfere with a wall of a generally tubular vessel to retain the body within the vessel. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37)

38. A medical device, comprising:
-
an elongate body; and a retaining segment extending along a length of the body and forming a fixed portion of an outer surface of the body, the retaining segment including a plurality of projections extending from the portion of the outer surface; wherein the plurality of projections are adapted to interfere with a wall of a generally tubular vessel in order to retain the body within the vessel; and one or more of the plurality of projections include micro-features positioned along the length of the projection for interfacing with the vessel wall, when the projections interfere with the wall, in order to enhance engagement of the one or more projections with the vessel wall.
