摘要：
A catheter assembly comprising a catheter handle (101) with a collet (118) disposed at a distal end. The collet is coupled to a strain relief (107) comprising a nut (122) and a strain relief projection (135). The collet comprises at least one leaflet (124, 125) and at least one collet spur (672, 682), and the nut comprises at least one ratchet (251). The collet is configured to couple to the nut, and the at least one ratchet is configured to interact with the at least one collet spur to securely fasten the strain relief to the catheter handle. The at least one leaflet is configured to couple to a catheter shaft.
