Deflectable tip access sheath

An access sheath, comprising:

• an elongated access sheath extending from a proximal portion to a distal portion, the proximal portion having at least one connector and an interface;
• at least one coil embedded within the access sheath, the coil reinforcing at least a portion of a lumen extending from the proximal portion to the distal portion;
• at least one additional lumen extending from the proximal portion to the distal portion and adapted to receive an optical system or a portion of an irrigation system;
• and
• at least one deflector filament operatively coupled to the distal portion and extending through the access sheath, the deflector filament and access sheath adapted for bending the distal portion of the access sheath at an angle,
• wherein the interface includes a housing with a first track and a control handle that is mechanically coupled to the deflector filament, the control handle is rotatably mounted within the housing upon a pivot point, wherein the control handle is configured to cause linear movement of the deflector filament within the access sheath with rotation of the control handle,
• the control handle includes a rotatable operative portion that extends out of the housing and a second portion that comprises an actuator assembly fixed to the deflector filament, and the actuator assembly comprises a first retention point that includes a first in that is slidable within the first track defined within the housing, wherein the first retention point includes a first slot that allows for relative linear motion of the first pin within the first retention point, wherein torque is transferred from the operative portion to the second portion through the pivot point which connects the operative portion and the second portion to rotate together.
