Patent ID: 7803130

Claim:
An access sheath, comprising: a proximal portion comprising a control handle disposed within a housing having a first track; a distal portion adapted for bending at an angle; an elongated portion extending from the proximal portion through the distal portion, the elongated portion comprising a working lumen and two additional lumens, one of said lumens adapted to receive an optical system; and at least one deflector filament in at least one of said additional lumens, the at least one deflector filament operatively coupled to the distal portion and extending to the proximal portion, deflector filament being mechanically coupled to the control handle, wherein the control handle is rotatably mounted within the housing such that rotation of the control handle urges linear movement of the deflector filament within the at least one of said additional lumens, the control handle comprises a rotatable operative portion that extends out of the housing and a second portion that comprises an actuator assembly that is fixed to the deflector filament, the actuator assembly comprises a first retention point that includes a first pin that is slidable within the first track defined within the housing, and wherein the first retention point includes a first slot that allows for relative linear movement of the first pin within the first retention point, and wherein torque is transferred from the operative portion to the second portion through a pivot point connecting the operative portion and the second portion to rotate together.
