Abstract
A system and method for positioning a medical instrument at a desired biological target tissue site is provided. The system includes an elongated sheath having a deflectable distal end configured to deflect or otherwise position at least a portion of a medical instrument during a surgical procedure allowing for the placement of the deflected portion adjacent or proximate to a predetermined target tissue surface. The positioning system may be incorporated into the medical instrument. The medical instrument may be an ablation system.

A method of positioning a medical instrument within a patient's body using a guide sheath during a surgical procedure, comprising the steps of:
- introducing into the patient's body the guide sheath having a deflectable distal end having a longitudinal axis and at least one lumen passing therethrough that is aligned along the longitudinal axis near the distal end;
- deflecting the deflectable distal end of the sheath within the patient's body;
- introducing the medical instrument into the guide sheath positioned within the patient's body toward a target tissue site;
- and
- advancing the distal end of the medical instrument through the at least one lumen to the deflectable distal end thereof for positioning at least a portion of the medical instrument within the deflected distal end of the guide sheath near the target tissue site.
