摘要： A bow shaped, integrated wire catheter apparatus and method of use for access to, and laser or other treatment within, cavities and organs in the human body, the apparatus having a curvilinear shape but flexible enough to assume a generally elongated shape such that the apparatus can be extended through the vasculature in the generally elongated shape and can assume the curvilinear shape when extended into a body cavity or organ, the curvilinear shape serving to securely position the apparatus adjacent a selected surface within the body cavity or organ for laser or other treatment with a laser delivery device or other functional device thereon, the apparatus having a central axis, the apparatus comprising a main catheter shaft having a proximal end and an apex seeking and stabilizing distal end, the main catheter shaft having material of construction or other mechanism or means for causing a portion of the catheter shaft to have a bowed shape adjacent its distal end, the main catheter shaft having at least one hollow lumen extending axially and at least partially therethrough such that a bow shaped portion defines and distinguishes an outer arcuate sidewall for placement in contact with the selected area or areas for laser or other treatment thereon, and an inner arcuate sidewall, at least the outer arcuate sidewall having one or more guide holes disposed thereon for selectively providing laser or other treatment on the selected surface by controllably advancing a laser delivery device or other functional device selectively through the one or more guide holes to the selected surface. The catheter apparatus can be made at least partially of superelastic and/or shape memory materials of construction.

摘要： A catheter device and a method for using same to facilitate removal of obstructive material in a human body channel. The catheter comprises an elongated body with a distal end portion adapted to be inserted within the channel and a proximal end portion. A lumen, extending lengthwise through said catheter body, supports a guidewire having a distal end along which the catheter body can be moved within the channel. A series of parallel, closely spaced fiber members extend through the catheter body from its proximal end and terminate near a distal end face of said catheter. Laser energy supplied at the catheter's proximal end is transmitted along the fiber members and is emitted forwardly therefrom at the catheter's distal end face. In one embodiment the catheter has a tapered nose portion for displacing obstructive material in the body channel before the emission of laser energy. In another embodiment, the fiber members are movable longitudinally in unison to sever and trap obstructive material which is removed from the body channel.

摘要： An instrument for removing an obstruction in an internal body channel comprises an elongated catheter body adapted for insertion into a body channel having a first lumen throughout its length. An elongated guide and laser transmission conduit extends through the lumen of said catheter body and is movable therein so that its distal end can be extendable beyond the distal end of the catheter body. The proximal end of the movable conduit is connected to a controlled source of laser energy. A treatment element is provided at the distal end of the catheter body for further reducing the channel obstruction following preliminary penetration thereof by the movable laser transmission conduit. The treatment element may be a fixed laser transmission conduit which terminates at the end of the catheter body or a dilation balloon near its distal end. In method steps utilizing the instrument, the movable conduit is positioned near a channel obstruction to enlarge a passage through and then serves to guide the catheter body into position so as to further enlarge or remove the obstruction using its treatment element.

摘要： A shaped catheter for accessing and treating preselected surfaces of cavities and organs within the human body, the apparatus including a tubular, shaped outer sheath with at least one guide hole and a tubular, flexible inner sleeve with a distal opening disposed adjacent the distal end, the inner sleeve slidably disposed within the outer sheath such that the distal opening of the inner sleeve can be operatively positioned adjacent the at least one of the guide holes and a laser delivery device or other functional device can be extended through the distal opening of the inner sleeve and through the guide hole on the outer sheath into the body cavity or organ. Providing a plurality of guide holes on the outer sheath will allow sequential treatment of the preselected surface within the body cavity or organ. Multiple TMR channels can be created or treatment at a number of sites can be made without moving or otherwise repositioning the outer sheath. The invention is also a method of use of such apparatus.

摘要： An apparatus for stabilizing a laser delivery device used during a surgical procedure by securing the laser delivery device to a surgeon's hand is defined by a finger mounting portion for securing at least one laser delivery device to at least one of the surgeon's fingers, and laser delivery device guide attached to the finger mounting portion for directing laser energy from the distal end of the laser delivery means. The finger mounting portion has at least one ring portion for removably encircling the surgeon's finger(s). Embodiments of the guide orient the laser delivery device either axially or trans-axially at a predetermined angle. The guide may be tubular with a preselected curvature, or tubular and adjustable so as to orient the laser delivery device into a plurality of positions. A locking mechanism couples the laser delivery device to the guide and rotating the guide may orient the laser delivery means into a plurality of predetermined positions. Laser delivery/fiber advance interlock mechanisms may be provided to prevent unintentional delivery of laser energy and unintentional advancement of the laser delivery device. A web-shaped guide means fits between and is secured to the surgeon's fingers and may have one or more aperture for guiding the laser delivery device.
