VIEWING SURGICAL SCOPE FOR MINIMALLY INVASIVE PROCEDURES

摘要

A viewing surgical scope apparatus is provided for minimally invasive surgical procedures such as transmyocardial revascularization (TMR) and capable of introducing a visualization scope and a working device such as an energy delivery device (e.g. an optical fiber). An elongated catheter has at least two working channels and a visualization device within the first working channel. A piercing needle having a lumen is within the second working channel and is translatable out of the distal end of the apparatus. A working device is provided in the lumen of the piercing needle and is translatable out of the distal end of the apparatus. An introducer assembly having an essentially rigid proximal portion and a flexible portion is coupled to the distal end of the catheter and a flexible cup member is coupled to the flexible distal portion of the introducer assembly.
