摘要：
A device for extending a lead according to some embodiments includes a body, a coil element coupled to the body, the body configured to cover the coil element during use, the coil element comprising an inner lumen sized to receive an outer surface of a lead, the coil element is movable between a first configuration in which the coil element slides over the lead, and a second configuration in which at least some coils grip the outer surface of the lead； an actuation mechanism operatively coupled to the coil element, the actuation mechanism configured to move the coil element between the first and second configurations； and a tether coupled to the lead via the body, the coil element, and/or actuation mechanism, the tether configured to extend further proximally than a proximal-most end of the lead and configured to transfer tension force applied to the tether to the lead.
