Locking mechanism for looped catheter

A locking catheter, comprising:

• an elongate shaft extending from a proximal end to a distal end and defining a lumen extending from the proximal end to the distal end;
• a hub defining a lumen extending from a proximal end to a distal end thereof and defining a lumen including extending from the proximal end to the distal end, the hub including a female luer lock having a body portion extending from a proximal end to a distal end and defining an aperture extending through a sidewall of the body portion of the female luer lock from an inner surface to an outer surface thereof, the hub coupled to the proximal end of the elongate shaft;
• a male luer lock extending from a proximal end to a distal end and having an outer coupling member and an inner tubular member, the inner tubular member defining a lumen extending from the proximal end to the distal end of the male luer lock, the male luer lock configured to be releasably coupled to the female luer lock;
• and
• a flexible member extending from a proximal end to a distal end, the distal end of the flexible member coupled to the elongate shaft, the flexible member extending through at least a portion of the lumen of the elongate shaft and a portion of the lumen of the hub, the proximal end of the flexible member extending through the aperture of the female luer lock such that the proximal end of the flexible member is exterior to the female luer lock;
• wherein when the male luer lock is coupled with the female luer lock, the flexible member is secured between an inner surface of the female luer lock and an outer surface of the inner tubular member of the male luer lock.

• a hub defining a lumen extending from a proximal end to a distal end thereof and defining a lumen including extending from the proximal end to the distal end, the hub including a first connection member coupled to the proximal end of the elongate shaft, the first connection member having a body portion extending from a proximal end to a distal end and defining a slot extending through a thickness of a sidewall of the body portion, the slot extending distally from the proximal end of the first connection member;
• a second connection member extending from a proximal end to a distal end and having an outer coupling member and an inner tubular member, the inner tubular member defining a lumen extending from the proximal end to the distal end of the second connection member, the second connection member configured to be releasably coupled to the first connection member;
