Minimally invasive apparatus for forming revascularization channels
First Claim
1. An articulating scope apparatus for performing transmyocardial revascularization comprising:
- a first working channel having an articulating distal portion and a proximal control member;
a handle having a distal portion and a second working channel in communication with the first working channel;
a linkage member coupling the distal portion of the handle to the control member;
whereby both movement of the handle, effecting articulation of the distal portion by the control member, and movement of a working device adapted for introduction within the first and second working channel can be controlled with a single hand.

Abstract
An apparatus for performing transmyocardial revascularization provides a closed-chest formation of a channel in a wall of a heart. An articulating scope in one embodiment includes a flexible distal portion which provides for a coupling of a surface of the heart to the distal portion. The articulating distal portion is coupled to a control member to provide articulation. Movement of the control member causes deflection, including articulation, of the generally flexible working end of the scope. The coupler may be a two way valve to provide both vacuum and flushing solutions. The articulating scope can be supported by a scope holder that is table mounted or mounted to the patient. An access port provides for the introduction of tools and instruments. An adaptor couples the access port with a handle. The handle provides a working channel for the introduction of an energy delivery device.
