Abstract: The instrument comprises an outer tube (1) fixed to the end of a flexible sheath (2), and an inner tube (3) displaceable in the outer tube and equipped with a head (5), to which is fixed a cylindrical casing (7) which has an inner boss (15). Arranged inside this casing are blades (10, 11) which are held axially on the outer tube by means of a collar (14) and which can swivel on the outer tube, this swiveling being ensured by the cylindrical casing (7), to be more precise by its end and by its inner boss (15) acting as a cam. This instrument, which is particularly robust, is intended for the removal of deposits formed on the inner walls of the arteries or veins.

Abstract: In order to destroy vascular deformations in the human body, a clamp is provided which is made from titanium. The clamp is expanded in the relieved state and is transferable into the clamping position by a clamping ring, which is displaceable along the clamp in the attached state. The clamp is introduced into the body by a probe, which has a tubular casing and a positioning bar guided therein. The clamp is transferred into the region of the deformation and applied at the application location as a result of the clamping ring being transferred into the clamping position. The transfer is caused by a relative movement between tubular casing and positioning bar. The probe is then released from the positioned clamp.

Abstract: A transurethral radio frequency apparatus for ablation of the prostate gland through the urethra formed by a wall, a probe consisting of a flexible elongate tubular member with proximal and distal extremities and sized so as to be adapted to be inserted into the urethra, and an ablation electrode carried by the distal extremity of the flexible elongate member. The flexible elongate tubular member is provided with first and second flow lumens for delivering a cooled fluid to the ablation electrode to cool the same. Means are connected to the probe to supply a coolant solution to the probe, to supply radio frequency energy to the electrode while it is being cooled, and to monitor the temperature of the ablation electrode so that the ablation electrode is maintained at a temperature below a predetermined temperature to spare the urethral wall from irreversible damage from the radio frequency energy delivered to the ablation electrode.

Abstract: A surgical manipulator arm has a first and a second control ball rotatably mounted and disposed at a proximal end and a distal end of an outer-shaft tube, respectively. The control balls are coupled to each other through coupling elements such, for example, as control wires so that rotational movements of the first control ball can be transmitted correspondingly to the second control ball or vice versa. The manipulator arm has an actuator portion connected to the first control ball and a follower portion connected to the second control ball for selectively and detachably mounting a handling part and an effector part of an instrument. The first and second control balls are mounted in such a way so as to permit their respective actuator and follower portions to rotate and pivot about the longitudinal axis of the outer-shaft tube. The central bore defines a connective passage from the actuator portion, through the outer-shaft tube, and to the follower portion.

Abstract: A closed end surgical cryoprobe instrument may have a probe shaft diameter of 3 millimeters or less and can achieve and maintain freezing zone temperatures close to that of the liquid cryogenic refrigerant. Using sub-cooled liquid nitrogen at approximately -208.degree. C. freezing zone temperatures as low as -206.degree. C. can be achieved in under 1 minute. The liquid nitrogen supply tube is provided with a plurality of small vent holes to vent gas formed or present in the refrigerant supply tube to the return refrigerant flow channel. The vent holes also allow small amount of liquid nitrogen to vent into the return flow channel to further reduce the temperature differential between the sub-cooled liquid nitrogen supply and the counter current flowing return refrigerant. Heat transfer is maintained through nucleate boiling. In place of vent holes, narrow slits may be provided in the supply tube. Alternatively, a sintered porous metal supply tube can be used as the vent means.

Abstract: A laparoscopic suturing device includes an elongate shaft having a distal end and a proximal end and an arcuate tissue piercing element permanently fixed to the shaft at the distal end, the arcuate tissue piercing element lying in a plane disposed substantially transversely to the shaft. The tissue piercing element is provided at a free end, spaced from the shaft, with an eyelet, and the device has a suture thread extending through the eyelet. A distal end portion of the device is inserted through a laparoscopic trocar sleeve and the shaft of the device is turned in one direction to insert the tissue piercing element with a first end portion of the suture thread into internal tissues of the patient, a second end portion of the suture thread remaining disposed outside the patient. The first end portion of the suture thread is grasped upon insertion through the tissues and then the shaft of the suturing device is turned in the opposite direction to remove the tissue piercing element from the internal tissues.

Abstract: A device for expanding the connective fatty tissue and correcting inverted nipples and improving symmetry of the human breast by means of gentle suction generated by respiratory means. The hollow dome is constructed of tinted, low-density, polyethylene which enables the user to monitor the degree of expansion she desires. The surrounding rim assures an air tight seal with the skin tissue. The pliable, high tensile quality of the hollow dome allows the user to squeeze and change the shape of the hollow dome on various locations on the breast to uplift and improve cleavage. A threaded nipple extends from top center of the exterior of the hollow dome which is attached to a pliable breathing tube and is fitted with a removable mouthpiece to facilitate orally evacuating the air surrounding the breast. A valve-timer controls the input and output of atmospheric pressure which creates a vacuum around the breast, and can be maintained for a selected number of seconds and minutes by the individual needs of the user.

Abstract: A method of analyzing astigmatism is disclosed which enables surgeons to ascertain what surgery may be required subsequent to initial surgery to achieve the preoperative aim of the initial surgery. The method includes determining a preoperative astigmatism, defining an aimed astigmatism and determining an achieved astigmatism following initial surgery. The astigmatism values are initially determined in a zero to 180 degree range and are doubled to convert them to a 360 degree range. An aimed induced astigmatism vector, a surgically induced astigmatism vector and a difference vector are calculated. Magnitudes and angles of the vectors can be calculated to provide astigmatism magnitude values and angle values for modifying parameters of future surgery for improved performance of future surgery and for statistical analysis. The method also provides a rationale for determining a treatment parameter when spectacle and corneal astigmatism do not coincide.

Abstract: An endoscopic surgical apparatus is provided for enabling the surgeon to access directly the surgical site during an endoscopic procedure. The apparatus includes an opening extending longitudinally through the apparatus and being configured and dimensioned to receive a hand therethrough. A first plate engages against the outer surface of the abdominal wall. A second plate is spaced from the first plate and is movable between a first position and a second position wherein the second plate is in close cooperative alignment with the inner surface of the abdominal wall. An adjustment member is mounted to the second plate and actuates movement of the second plate between its first position and its second position. A first sealing member inhibits the flow of gas through said opening and is formed by a pair of overlapping seals. A flexible sleeve extends between the first and second plates and adjusts in length to accommodate various thicknesses of the abdominal wall.
