    Abstract: A mold and method for forming a balloon for dilatation catheters, particularly balloons with a prismlike shape with a transverse polygonal cross section when the internal pressure is at atmospheric conditions. Upon inflation to higher internal pressures, the balloon assumes a normal circular cross section. The balloon shape is particularly suitable for balloons formed of polyethylene terephthalate and the like which are not readily heat settable. Reduced deflated profiles are obtained. The mold is formed by first making a preformed core member which has the shape and dimensions which are desired for the balloon. A heat-formable tubular member, preferably formed of borosilicate glass such as PYREX, is disposed about the core member, subjected to heat and an internal vacuum so as to be shaped onto the exterior of the core member. Once shaped, the tubular member is allowed to cool and set, the core member is dissolved away, leaving the shaped glass mold having an internal molding chamber with the desired shape and dimensions for the inflatable balloon.

    Abstract: A detachable button system has a fixed component permanently attached to a garment and a detachable button component. The fixed component a disc-shaped base and a cylinder extending perpendicularly from said base, said cylinder featuring a plurality of tabs projecting perpendicularly from the cylinder and parallel to the base. The detachable portion had an interior cavity for receiving the cylinder, the interior cavity including a plurality of slots corresponding to the plurality of tabs, the slots receiving said tabs. The tabs vary across their width so as to provide a friction fit when the cylinder of the fixed component is inserted into the internal cavity of the detachable component and the detachable component is rotated.

    Abstract: Systems and methods are provided for determining the pressure-volume relationship for one or more chambers of a heart, e.g., to guide pharmacologic or other treatment of congestive heart failure. An implantable device includes a catheter including a distal end sized for introduction into a chamber of a heart, a pressure sensor for measuring pressure within the chamber, and a sensor for measuring fluid volume within the chamber. A processor coupled to the catheter obtains pressure data from the pressure sensor and fluid volume data from the volume sensor. The processor approximates fluid volume within the chamber as a function of time and determines one or more pressure-volume loops based upon the pressure data and the fluid volume. In one embodiment, the catheter is a lead and a controller which identifies changes in determinants of cardiac output. Changes in medical therapy are guided by pressure volume loop data generated.

    Abstract: A power apparatus for cleaning pine needles and other debris from overhead rain gutters while operated by an individual who is standing on the ground. A disk with protruding plastic apikes is attached to a gear assembly and electric motor. The disk rotates and throws debris from the gutter. A guard prevents said thrown debris from landing on the roof. The electric motor and gear assembly are located inside a housing which is at one end of a crossarm. A guide, fitting underneath said housing, can be adjusted to provide the proper amount of contact between the disk and debris laying in the bottom interior of the gutter. At the opposite end of said crossarm to the housing is a dislodge blade used to shift debris which may be unreachable by said disk especially debris located directly beneath gutter hangers. The dislodge blade is used to push this debris to a more accessible area of the gutter where the, disk is then used. The crossarm is connected to an extendible pole which permits use of the apparatus with gutters of various heights. Controls for the motor are located in the pole handle. The apparatus can be partially disassembled for easy shipment and storage.

    Abstract: The present invention comprises a tubular shunt for insertion into a fluid vessel in a living creature constructed of an elastically deformable material that reduces in circumference when stretched longitudinally so that the ends of the shunt may be easily inserted into openings in a blood vessel and where the material expands circumferentially when allowed to axially contract such that the ends of shunt press against the vessel wall to secure the shunt and form a water tight seal to permit fluid to flow through the tubular conduit of the shunt. A method for shunting fluid-flow in a portion of a vessel in a living creature is also disclosed wherein a shunt of the present invention is stretched longitudinally so that the ends of the shunt contract and then inserted into a lumen of a blood vessel. Following insertion of the shunt, the shunt is allowed to return to its relaxed geometry so that it forms a fluid tight seal with the interior of the lumen.

    Abstract: A percutaneous discectomy system 20 having a bendable discectomy probe 22 and steerable cannula 24 allows for a wide range of positions relative to the discectomy tissue to be severed. The bendable discectomy probe 22 includes a bendable section 78, 86 which can allow the probe 22 to be bent more than 90.degree. and still maintain the function required in order to sever and remove tissue. The steerable cannula 24 has a similar bendable section 102 which can appropriately position the end 50 of the discectomy probe 22 in order to address tissue to be removed.
