Abstract:
1. A removable cap for connection to an input port of a catheter, comprising: a proximal end having a lumen configured to house a guidewire therethrough; a distal end configured to reversibly mate with a luer lock of the input port of a catheter, the distal end having a lumen configured to house the guidewire therethrough; and a tubular body between the proximal end and the distal end, wherein the tubular body comprises an anti-migration feature transformable between a first configuration to allow slidable movement of the guidewire within the cap in a first direction toward the patient, and a second configuration to prevent slidable movement of the guidewire within the cap in the first direction toward the patient, wherein the anti-migration feature comprises a zone of the lumen having a tapered sidewall and a plurality of beads operably connected to the sidewall, the beads selectively exerting a radially compressive force on the guidewire when the guidewire moves in the first direction, and wherein the second configuration of the anti-migration feature allows slidable movement of the guidewire within the cap in a second direction opposite the first direction.
