Vascular access systems having a guidewire anti-migration feature

摘要

Disclosed herein is 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. Systems and methods are also disclosed.

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 the 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 comprising a spring-loaded element and a plurality of arms configured to transmit a radial inward force to the guidewire when a force is applied on the arms by the spring-loaded element, the 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 plurality of arms are circumscribed by the tubular body.
