Claim Text:
1. A medical device assembly comprising: an elongate tubular member having a proximal end and a distal end; a handle assembly coupled to the proximal end of the elongate tubular member, the handle assembly including a housing having a bore extending therethrough and a locking mechanism, the locking mechanism comprising: an elongate member extending along the flexible member, the elongate member selectively longitudinally movable with respect to the housing of the handle assembly; wherein the housing of the handle assembly includes a projection extending into an arcuate opening of the actuator, the actuator further including a detent, wherein the detent is a tang of the actuator, wherein the tang of the actuator engages the projection in the second position of the actuator to restrict pivotable movement of the actuator to the first position of the actuator; wherein in the first position of the actuator the elongate member is longitudinally movable along the flexible member and in the second position of the actuator the flexible member is deformed against the elongate member via the actuator to restrain longitudinal movement of the elongate member relative to the flexible member through increased frictional forces between the flexible member and the elongate member; wherein the bore of the housing includes a first portion having a first diameter and a second portion having a proximal end, a distal end, and a second diameter greater than the first diameter, wherein the first portion has an end that abuts either the proximal end or distal end of the second portion and the flexible member is positioned in the second portion of the bore and extends from the proximal end to the distal end of the second portion; and wherein the flexible member has an outer diameter greater than the first diameter of the first portion of the bore.
