  • Patent number: 6939463
    Abstract: A filter for a spa or pool, having a filter body which receives a filter bag having a sheath encompassing the exterior of the filter body and a pocket extending inwardly from the front end of the sheath into the filter. Operation of the spa water circulation system draws spa water into the filter bag pocket while concurrently spa water is drawn transversely through the filter bag sheath and auxiliary spa water openings into the filter body. An O-ring encircles the upper portion of the filter bag to releasably retain such bag to the filter body during operation of the spa water circulation system.

  • Patent number: 6939321
    Abstract: A balloon catheter and a method of making the balloon catheter, having a balloon which is bonded to an elongated shaft, and which has a first layer and a second layer and an improved strong bond between the balloon and the shaft. One aspect of the invention is directed to a balloon in which the balloon first layer has at least a section with a gas plasma-etched or chemical solution-etched surface for improved bondability. Another aspect of the invention is directed to a balloon in which the balloon first layer has a proximal end section bonded to an outer surface of the shaft and the balloon second layer has a proximal end section bonded to an inner surface of the shaft, and, in one embodiment, at least a section of the balloon first layer has a gas plasma-etched or chemical solution-etched surface.

  • Patent number: 6939362
    Abstract: An expandable cage used in conjunction with an embolic filtering device has a strut configuration including a proximal strut assembly coupled to a distal strut assembly. A filter can be attached to the distal strut assembly which has an inlet opening. The proximal strut assembly is “offset” from the distal strut assembly in that these proximal struts extend substantially along the vessel wall of the patient, rather than being “centered” in the body vessel when the cage is expanded in a body vessel. As a result, there is little cage structure directly in front of the opening of the filter, resulting in a virtually unobstructed opening for the filter.

  • Patent number: 6939373
    Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the peaks that are adjacent the curved portion of the undulating link are shorter than other peaks in the same cylindrical ring to prevent overlap yet still achieve a very low profile, tightly crimped stent onto a catheter.

  • Patent number: 6928906
    Abstract: A heavy duty, large self-forming socket having a plurality of retractable gripping pins bundled in parallel and held in a frame within a housing is disclosed. The frame is positioned axially within the housing by radially extending, elongated hold elements that are positioned circumferentially around the housing. Slots in the housing exterior allow efficient inspection of the position of holes into which the hold elements are installed. A collar with shelf around the center pin protects the bias spring for the pin from over-compression. The gripping pins may be held to the frame by spring clips. An adaptor is attached wherein a secondary operation is used to remove the adaptor from the square end of the socket. The self-forming socket is well suited for use with valves and controls for water, gas, sewage conduits and piping.

  • Patent number: 6929768
    Abstract: A method of making a catheter balloon or other expandable medical device, and a balloon or other device formed thereby, in which at least a portion of a tubular, wrapped sheet of polymeric material is heated with laser radiation to form a fused seam extending along at least a section of the length of the tubular body. In one embodiment, the portion of the sheet heated by laser radiation is less than the entire area of the sheet, so that the fused seam is formed by heating portions of the sheet without heating sections of the sheet spaced apart from the fused seam. In one embodiment, the sheet of polymeric material comprises a polymer having a porous and preferably a node and fibril microstructure, which in one embodiment is selected from the group consisting of expanded polytetrafluoroethylene (ePTFE) and expanded ultra high molecular weight polyethylene.

  • Patent number: 6929333
    Abstract: The system and method for monitoring wear of one or more aircraft parts, such as an aircraft brake, an aircraft tire, a standby system, and landing gear. One or more sensors are provided for sensing a parameter of usage, and an estimate of usage of the part can be determined based upon the signal indicating the sensed value of the parameter of usage of the aircraft part. A plurality of sensors can be provided for sensing usage of a plurality of parts of the aircraft, and the estimate of usage of the part can be stored for access of the estimate by ground personnel. As applied to monitoring wear of an aircraft brake, a linear brake wear indicator attached to the brake moves a discrete distance when the brake is actuated, and a linear position encoder measures the distance travelled by the linear brake wear indicator as an indication of brake usage.

  • Patent number: 6927359
    Abstract: An improved expandable stent for implantation in a body lumen, such as an artery, and an improved method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cut cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements, the elements having a rectangular cross-section from cut-to-cut. The individual radially expandable cylindrical elements are disposed in an undulating pattern. The stent is manufactured by direct laser cutting from a single metal tube using a finely focused laser beam originating from a diode pumped fiber laser with an external pulse generator and passing through a coaxial gas jet structure to impinge on the working surface of the tube as the linear and rotary velocity of the tube is precisely controlled. To optimize the cut, the laser parameters may be adjusted and/or the laser pulse may be shaped.
