    Abstract: A medical device for removing a material from a hollow anatomical structure is provided. The device may include a shaft member. The device may include an expandable centering element near the distal end of the device. The device may include a macerator element either attached to the shaft or independent and freely moveable from the shaft. Alternatively, the device may include a rotating wire attached to the macerator element. The device may include an aspiration lumen in for removal of material. The device may include a drive shaft attached to a motor and used to rotate the macerator element. The device may be used in combination with a distal occlusion element, which may be either a radially expandable filter or balloon member.

    Abstract: A catheter assembly includes an elongated member having an ultrasonic beacon disposed adjacent to a distal end portion of the elongated member, a power supply releasably attachable adjacent to the proximal end of the elongated member, and a catheter. The distal end portion of the elongated member with the ultrasonic transmitter is inserted into an anatomical structure of the human body, and the ultrasonic transmitter is powered by the power supply. Using conventional medical ultrasonography equipment, a technician is able to observe and/or track on a display an image of the internal structure of the human body and an image such as an illuminated bright spot representing the energized ultrasonic beacon. After locating the elongated member, the power supply is removed, and the catheter is slid onto the elongated member to locate the catheter tip. Thereafter, the elongated member is removed.

    Abstract: An endovascular laser treatment device for causing closure of a blood vessel uses an optical fiber adapted to be inserted into a blood vessel. An inner sleeve is arranged around a distal portion of the optical fiber core such that both distal ends of the inner sleeve and the optical fiber core form an enlarged light emitting face. The enlarged emitting face provides substantially lower power density while providing the same amount of total energy during a treatment session. An outer sleeve arranged around the inner sleeve acts as a spacer to position the light emitting face away from an inner wall of the blood vessel. The enlarged light emitting face and the outer sleeve acting as a spacer reduces the possibility of thermal run-away and device damage, and reduce the possibility of vessel perforations, leading to less bruising, post-operative pain and other clinical complications. In yet another aspect of the present invention, a spacer comprises an inner sleeve and an outer sleeve both arranged around a distal portion of the core to prevent the laser light from traveling laterally and to position the light emitting face away from an inner wall of the vessel. The inner sleeve can be a heat resistive material such as ceramic and the outer sleeve can be, for example, a metallic sleeve to provide structural integrity and strength to the distal section of the treatment device.
