Abstract: The present disclosure provides a catheter design tool and methods thereof for selecting or designing an optimal catheter profile for a particular patient or group of patients. For example, the tool includes a data set (e.g., input into the system) pertaining to a plurality of anatomy parameters and a plurality of catheter parameters to determine one or more catheter profiles that allow the best implant efficacy for a particular patient or group of patients. Specifically, the tool evaluates the efficacy of a particular catheter profile for use with a particular patient, the most optimal catheter profile from a plurality of catheter profiles for use with a particular patient, and/or the most optimal catheter profile from a plurality of catheter profiles for use with a group of patients.

Abstract: A medical electrical lead includes a proximal insulation segment, a distal insulation segment, a conductor extending within the proximal and distal segments, and an electrode coupled to the conductor and disposed in proximity to a distal end of the distal insulation segment. A fixation element of the lead is coupled to a distal end of the proximal insulation segment and includes a wire wound in a helix, which extends distally from the proximal segment, over the distal insulation segment.
