A spring element for a contact force sensing medical catheter. The spring element includes a first ring, a second ring spaced apart from the first ring, a plurality of struts connecting the first ring to the second ring, and a plurality of interlocking features. The second ring and the first ring are coaxially aligned with a longitudinal axis of the spring element. The plurality of struts is configured to permit elastic, relative axial and radial displacement between the first ring and the second ring. The plurality of interlocking features is configured to limit the relative axial and radial displacement between the first ring and the second ring.

An illustrative anchoring mechanism is provided for attachment to an implantable subcutaneous lead to facilitate anchoring at the distal tip of the lead. The anchoring mechanism is attached to an opening in a distal portion of a subcutaneous lead prior to implantation. The anchoring mechanism may be designed to avoid covering the sensing electrode of the subcutaneous lead, to prevent interference with sensing. Use of such an apparatus may reduce the number of incisions needed to perform implantation.
