Locking catheter
First Claim
1. A locking catheter, comprising:
- an elongated body member defining a central lumen and comprising a distal portion and a proximal portion, at least a portion of the elongated body member for placement within a patient;
a first proximal member disposed at the proximal portion of the elongated body member and defining a central passageway extending therethrough and coaxial with the lumen;
an elongated flexible member comprising a first end and a second end, the first end coupled to the distal portion of the elongated body member, the elongated flexible member extending through both at least a portion of the central lumen of the elongated body member and the central passageway of the first proximal member with the second end disposed external to the elongated body member; and
a second proximal member releasably couplable to the first proximal member to allow selective locking and unlocking of the elongated flexible member therebetween, the second proximal member defining a central passageway extending therethrough and a separate channel extending therethrough, the elongated flexible member extending through the separate channel and being slidable therethrough to allow the distal portion of the elongated body member to be drawn toward the proximal portion of the elongated body member to form a loop in the distal portion when the first and second proximal members are decoupled, the central passageway of the second proximal member extending coaxially from the central passageway of the first proximal member and the elongated flexible member being compressed between the first and second proximal members and non-slidable through the separate channel to secure the loop when the first and second proximal members are coupled together.

Abstract
An apparatus and method for locking a catheter within a patient enables the catheter to be easily and securely locked and prevents the catheter from being inadvertently unlocked. The locking catheter includes an elongated body member including a proximal portion and a distal portion, a first proximal member, an elongated flexible member, and a second proximal member releasably couplable to the first proximal member to allow selective locking and unlocking of the elongated flexible member therebetween. The second proximal member includes a channel. The elongated flexible member extends from the distal portion of the elongated body member, through the first proximal member, and through the channel of the second proximal member. The elongated flexible member is slidable through the channel thereby allowing the distal portion of the elongated body member to be drawn toward the proximal portion of the elongated body member to form a loop in the distal portion of the elongated body member.
