Abstract:
1. A therapy assembly configured for at least partial insertion in a living body, the therapy assembly comprising: a therapy delivery element comprising a proximal end with a plurality of electrical contacts configured to electrically couple with an implantable pulse generator and a distal end with a plurality of electrodes that are electrically coupled to the electrical contacts at the proximal end; an introducer with a lumen configured to receive the therapy delivery element; a plurality of fixation structures disposed radially around the therapy delivery element proximate the electrodes, the fixation structures comprising wires having a diameter in a range between about 0.004 inches and about 0.020 inches, the wires each having a first proximal end attached to the therapy delivery element and a second distal end that is not attached to the therapy delivery element and is configured to slide along the therapy delivery element, wherein the fixation structures are configured to collapse inwardly to a collapsed configuration when inserted into the lumen of the introducer and to deploy to a deployed configuration when the introducer is retracted, wherein, in the deployed configuration: a fitting located at a proximal end of the introducer that releasably locks the therapy delivery element to the introducer, wherein torque applied to the fitting is substantially transmitted to the distal end of the therapy assembly.
