Abstract:
A steerable, direct myocardial revascularization catheter comprising:a catheter body having an outer wall, proximal and distal ends and at least one lumen extending therethrough;a control handle at the proximal end of the catheter body;a tip section comprising a flexible tubing having proximal and distal ends and at least one lumen extending therethrough, wherein the proximal end of the tip section is fixedly attached to the distal end of the catheter body;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 electrically connected to the electromagnetic sensor and extending 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;an optic fiber having a distal end and a proximal end, said optic fiber extending through the control handle, a lumen in the catheter body and a lumen in the tip section, said distal end of the optic fiber being substantially flush with the distal end of the tip section; andmeans for deflecting the tip section by manipulation of the control handle.
