Abstract
Medical leads have one or more openly coiled filars and a distal body coupled to the openly coiled filars. The openly coiled filars provide a lead with compliance and elasticity while the distal body provides the firmness needed for placement and support of the electrodes. The openly coiled filars may transition to a linear distal portion that extends to the distal body, and the distal body may have proximal tines that fold proximally to become adjacent to the linear distal portion of the filars. The openly coiled filars may instead extend to the distal body and the proximal tines may be laterally arced to then fold against the lateral surface of the coiled filars. The tines may fold distally during explantation to allow the distal body to release and exit the body.
