Intraoperative myocardial device and stimulation procedure

An apparatus for stimulating angiogenesis in myocardium, the apparatus comprising:

• a body member;
• a neck member connected to said body member;
• a neck adjustment mechanism for adjusting said neck member relative to said body member having a distal section slidably connected within said body member, wherein a proximal section of said neck adjustment mechanism has a series of grooves;
• a head member connected to a proximal end of said neck member, said head member defining a stop member adapted for engaging a heart;
• a laser energy delivery device for ablating tissue to form stimulating zones having a distal end and a proximal end configured to optically connect to a laser energy source, and translatable through and egressible from said head member;
• a laser energy delivery device advancement mechanism attached to said body member for controlling by discrete and incremental movement said distal end of said laser energy delivery device to pre-selected positions relative to said head member, whereby firing said laser energy delivery device reproducibly creates said stimulating zones at said pre-selected positions;
• and
• a locking member pivotally attached to said body member having a distal end with a projection configured to fit within one of said series of grooves and a proximal end having a thumb actuated portion connected to a spring bias member for urging engagement of said projection into one of said series of grooves, whereby when said locking member is disengaged said neck member can be adjusted thereby adjusting a length of exposure of said distal end of said laser energy delivery device from said stop member.
