Abstract
A medical electrode delivery tool includes a distal portion coupled to an elongate shaft. The distal portion includes a generally ellipsoidal segment. The ellipsoidal segment includes a concave surface forming a cavity having an opening facing in a direction away from a longitudinal axis of the shaft and a convex surface overlying the concave surface and tapering to a distal end of the ellipsoidal segment.

A medical electrode delivery tool, comprising:
- an elongate shaft;
- and
- a distal portion coupled to the shaft, the distal portion including:
- a generally ellipsoidal segment, the ellipsoidal segment including a concave surface forming a cavity having an opening facing in a direction away from a longitudinal axis of the shaft and a convex surface overlying the concave surface and tapering to a distal end of the ellipsoidal segment;
- and
- a holding element disposed within the cavity for holding an electrode or a portion of a lead body bearing the electrode within the cavity.
