Abstract
A steerable, direct myocardial revascularization catheter comprises a catheter body, a control handle, a tip section, and a means for deflecting the tip section by manipulation of the control handle. The catheter body has an outer walls proximal and distal ends and at least one lumen extending therethrough. The control handle is situated at the proximal end of the catheter body. The tip section comprises a flexible tubing having proximal and distal ends and at least one lumen extending therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. The catheter also comprises an electromagnetic sensor in the distal portion of the tip section for producing electrical signals indicative of the location of the electromagnetic sensor. An electromagnetic sensor cable is electrically connected to the electromagnetic sensor and extends through the tip section, catheter body and control handle for carrying electrical signals from the electromagnetic sensor to a circuit board located in the control handle. The catheter further comprises an optic fiber having a distal end and a proximal end. The optic fiber extends through the control handle, a lumen in the catheter body and a lumen in the tip section. The distal end of the optic fiber is substantially flush with the distal end of the tip section.
