ABSTRACT:
A controlled advancement laser ablation device is provided for precise ablation of body matter. The laser ablation device includes a handle portion having proximal and distal openings and a fiber advancing device having a stationary member and a movable member. The movable member is movable towards and away from the stationary member. A fiber casing is included having proximal and distal ends. The distal end is secured to the proximal end of the handle portion and the proximal end is secured to the stationary member. At least one optical fiber is included having proximal and distal ends. The distal end is extendible through the handle portion and a portion of the fiber, defined between the proximal and distal ends, is secured to the movable member. A laser energy generator is optically connected to the proximal end of the optical fiber. The handle portion includes a self-biasing advancing mechanism. The self-biasing advancing mechanism includes a guide member positioned within at least a portion of a channel extending within the handle portion. At least one biasing member is operatively connected to the guide member to guide the guide member proximally as a proximal force is applied to the distal end of the optical fiber and to guide the guide member distally when laser energy is transmitted to the optical fiber by the laser energy generator. Controlled advancement mechanisms include constant and/or variable rate springs, motors, and other mechanisms which can be coordinated with the laser energy generator to advance the laser energy transmission mechanism as the targeted substance is ablated. The device is suitable for use in transmyocardial revascularization (TMR) and angioplasty procedures.
