    摘要: 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.

    摘要: The present disclosure relates to a method apparatus for transmyocardial revascularization. The apparatus includes an incision needle for creating an incision within a patient's heart to define a channel, and an electrocautery assembly operatively associated with the incision needle for transferring thermal energy to an inner surface of the channel to reduce bleeding therefrom and to prevent the channel from closing. Preferably, thermal energy is not transferred to the epicardium to create a flap or channel cap after the cylindrical incision needle is removed from relevant tissue to reduce bleeding from the channel.

    摘要: A method for performing transmyocardial revascularization (TMR) comprises the steps of creating an incision in an outer portion of heart tissue of a patient and creating a channel in the patient's myocardium through the incision by advancing a channel creating device into the myocardium beyond the depth of the incision to remove myocardial tissue without removing all outer portion heart tissue coinciding with the channel. As a result, the remaining outer portion tissue acts as a cap to reduce bleeding from the channel subsequent to removal of the channel creating device. The cap may be in the form of an annular flap of myocardial/epicardial tissue. The channel creating device used to create the channel with the method can be either a mechanical coring device or an advancing lasing device.
