LOCKING CATHETER HUB
First Claim
1. A drainage catheter, comprising:
- an elongate body member defining a central lumen and comprising a distal portion and a proximal portion, at least a portion of the elongate body member adapted for placement within a patient;
an elongate flexible member operable connected to the distal portion of the elongate body member and extending through the lumen in at least the proximal portion of the elongate body member; and
a hub comprisinga base having a proximal end, a distal end, and an internal passageway, an outer surface between the proximal and distal ends, and a side lumen extending from the internal passageway to an opening in the outer surface, wherein the outer surface includes an engagement element and a mating surface portion, and wherein the base distal end is fixed to the elongate body member proximal portion, anda collar having a proximal end, a distal end, an inner surface extending from the proximal end to the distal end and an outer surface extending from the proximal end to the distal end, the collar further having a side lumen extending from the inner surface to the outer surface and wherein the inner surface of the collar includes a mating surface portion and a counter element,wherein the elongate flexible member extends through the base side lumen and the collar side lumen, andwherein the hub has an unlocked position where the engagement element and the counter element are not in engagement and a locked position where the engagement element and the counter element are in engagement, the collar is tightened on the base and the elongate flexible element is clamped between the mating surface portions of the base and the collar.

Abstract
A drainage catheter, comprising an elongate body member, an elongate flexible member and a hub, the hub including a base and a collar, the base an internal passageway and a side lumen and an outer surface including an engagement element and a mating surface portion, and the collar including a side lumen extending from the inner surface to the outer surface and wherein the inner surface of the collar includes a mating surface portion and a counter element, wherein the elongate flexible member extends through the side lumen side lumens, and wherein the hub has an unlocked position where the engagement element and the counter element are not engaged and a locked position where the engagement element and the counter element are engaged, the collar is tightened on the base and the elongate flexible element is clamped between the mating surface portions of the base and the collar.

20. A drainage catheter, comprising:
-
an elongate body member comprising a distal portion and a proximal portion, at least a portion of the elongate body member for placement within a patient; an elongate flexible member operably coupled to the distal portion of the elongate body member and extending through the lumen in at least the proximal portion of the elongate body member; and a hub comprising; a base having a proximal end, a distal end, and an outer surface extending between the proximal and distal ends, the base further including a screw thread disposed on the outer surface, the outer surface having a mating surface portion, the base distal end fixed to the elongate body member proximal portion, the elongate body member and base together defining a central device lumen, and a collar having a proximal end, a distal end and a central lumen, an inner surface extending from the proximal end to the distal end and an outer surface extending from the proximal end to the distal end, a screw thread disposed on the inner surface and configured to mate with the screw thread of the base, the inner surface comprising a mating surface portion, the mating surfaces of the base and the collar having mismatched profiles and configured such that when the collar is tightened on the hub using the corresponding screw threads, the mating surfaces are forced together to lock the collar to the base, wherein the elongate flexible member has a proximal portion that exits the central device lumen proximal the proximal end of the base and is disposed between at least a portion of the outer surface of the base and the inner surface of the collar such that when the collar is locked to the base, the elongate flexible member proximal portion is fixed between the base and the collar.
