Claim 10:
11. A drainage catheter for introduction in a patient, comprising:
an elongated tubular member, the tubular member having a distal end adapted for insertion into a patient, a proximal end, and a tubular member passageway extending longitudinally therethrough;
a drainage catheter hub attached to the proximal end of the tubular member, the drainage catheter hub including a locking arm connected to a hub body, the hub body defining a hub fluid passageway in fluid communication with the tubular member passageway, the hub body further defining an aperture extending between an exterior surface of the hub body and the hub fluid passageway, the drainage catheter hub also including a sealing element received in the aperture;
a tension member connected to the distal end of the elongated tubular member and extending proximally through the tubular member passageway, into the hub fluid passageway, and through the sealing member to provide a proximal tension member segment clampable by the drainage catheter hub;
wherein the hub body has an upper body portion defining a clamping hub surface for clamping the proximal tension member segment, a right side face positioned to a first side of the upper body portion, and a left side face positioned to a second side of the upper body portion;
wherein the locking arm defines an inner arm surface facing inwardly to the hub body, the inner arm surface including a right side inner arm surface portion for covering a surface of the right side face of the hub body, a left side inner arm surface portion for covering a surface of the left side face of the hub body, and a clamping inner arm surface portion between the right side arm inner surface portion and left side inner arm surface portion and configured for clamping the proximal tension member segment;
the locking arm having a distal locking arm portion configured to cover the aperture;
the distal locking arm portion defining an opening sized and positioned to receive the proximal tension member segment therethrough;
the locking arm positionable to an unlocked position for leaving the proximal tension member segment in an unclamped condition between the clamping inner arm surface portion and the clamping hub surface; and
the locking arm positionable from the unlocked position to a locked position for clamping the proximal tension member segment between the clamping inner arm surface portion and the clamping hub surface and in which the right side inner arm surface covers the surface of the right side face of the hub body and the left side inner arm surface covers the surface of the left side face of the hub body.
