  • Patent number: 5403350
    Abstract: A device for studying patello femoral articulation in a magnetic resonance machine has an armature with a step-cut slot. The armature is pivoted to a base frame. A leg lever has two ends, a first end with a padded cross-member for accommodating lower legs or ankles, and a second end that is pivotally mounted to the base frame. The leg lever is interconnected with the step-cut slot, so that the leg lever may be positioned in vertical increments within the slot. A secondary lever is pivotally mounted to the base frame at the same location as the leg lever, and is also fixedly attached to an end portion of the leg lever. The leg lever can be incrementally raised and lowered within the step-cut slot. Furthermore, the first end of the leg lever is biased upward. The apparatus may be substantially metal-free so that the device will not distort the magnetic field inside the magnetic resonance machine.

  • Patent number: 5394808
    Abstract: A folding table has a unitary table top formed of molded plastic preferably having an outer shell of non-cellular plastic with a filling of light weight hardened foam. Pairs of spaced apart sockets are formed in the table top material at the underside of the table top and a cylindrical bushing is disposed in each socket. One of a pair of pivotable leg assemblies is coupled to each pair of sockets by a pair of pivot axle projections that extend into the sockets and bushings. At least one of the sockets of each pair has a depth at least equal to the combined distances that the pivot axle projections extend into the pair of sockets. This enables entry of the pair of pivot axle projections into the pair of sockets by inserting one of the projections deeply into the one socket and then partially withdrawing that projection while guiding the other projection into the other socket of the pair.

  • Patent number: 5395360
    Abstract: An approach for sterilizing and reusing a fiber optic probe is disclosed. The fiber optic probe includes an input end having an axially projecting stem containing the input face of the fiber. Prior to sterilization, a cap member is mounted on the stem to prevent damage by the pressurized steam encountered in an autoclave. After being sterilized, the probe is brought to the operating theater. The sterilized probe is transferred to the sterile field while the stem and cap member are extended beyond the sterile field. The cap member is then removed and the input end of the probe is connected to the source of laser radiation. Using this approach, the probe can be sterilized without damage and reused without contaminating the sterile field.

  • Patent number: 5395361
    Abstract: A catheter system for intraluminal laser surgery is disclosed. The catheter system comprises an elastically expansible catheter sheath housing a plurality of optical fibers arranged in a circular array about an inflatable balloon. Inflation and deflation of the balloon expands and contracts the diameters of both the optical fiber array and the catheter. Throughout inflation and deflation of the balloon the distal ends of the fiberoptic light guides are maintained generally parallel to the lumen wall thereby maximizing the safety and efficacy of the procedure.

  • Patent number: 5389096
    Abstract: A method and apparatus are described for percutaneous myocardial revascularization of a human heart. A deflectable elongated flexible lasing apparatus is used which includes a source of laser radiation, an elongated flexible radiation conveying means for conducting the laser radiation to a lens on the distal end of the radiation conveying means for focusing the laser radiation, and control lines for deflecting the distal end of the radiation conveying means. The control lines are secured to the distal end of the radiation conveying means for changing the angle of deflection of the distal end of the radiation conveying means. The lasing apparatus is guided to an area within the patient's heart, and the distal end of the lasing apparatus is directed to an area of interest where the inner wall of the heart is irradiated with laser energy to form a channel through the myocardium for a desired distance. In a preferred embodiment, channels are formed without perforating the epicardium of the heart.

  • Patent number: 5388531
    Abstract: A substantially recyclable shipping platform apparatus for supporting and transporting loads, in which the apparatus is easily disposable and recyclable after use. A plurality of substantially elongated pylons are attached between a top platform and a bottom panel to increase the integrity of the apparatus to more effectively support the load material placed upon the platform. The bottom panel is constructed with articulateable flaps which are used to secure the pylons to the bottom panel. Each of these flaps are configured to maximize contact with, and stability of, the pylons, and are further configured to correspond to the specific shape of the interior region of each respective pylon they are attached to. A tear strip may be embedded within the platform and/or bottom panel for purposes of reducing the overall size of the apparatus when disposal is desired.

  • Patent number: 5383875
    Abstract: A control lever assembly adapted for use with a powered surgical instrument which prevents the instrument from being inadvertently or accidentally activated. The assembly 10 includes a depressible control lever 20 for controlling the action of the instrument and a second safety lever or latch 30 which engages the trigger pin 6 of instrument only when selectively positioned with respect to control lever 20. Control lever 20 is secured to cutting device 2 by a mounting bracket 12. Safety latch 30 is pivotally carried by control lever 20 for shiftable movement between a safety position and an operational position. In the operational position, safety latch 30 engages trigger pin 6 when control lever 20 is depressed. Safety latch 30 cannot be switched from its safety position to its operational position when control lever 20 is depressed; therefore, the instrument is "locked-out" and cannot be inadvertently activated even when control lever 20 is depressed.

  • Patent number: 5383900
    Abstract: A single-use tape applicator includes a pair of sidewalls spaced laterally from one another to define a tape storage enclosure, and two posts extending between the sidewalls and spaced from one another to define a generally oval-shaped run. A closed loop of backing material is supported by the posts and is movable relative to the posts along the run. The length of the loop is substantially equal to the length of the run. A piece of tape coated on one side with an adhesive material is supported and carried on the backing material. The enclosure defines an opening through which the tape is pulled from the backing material and dispensed.

  • Patent number: 5382247
    Abstract: An electrosurgical tip for the application of electromagnetic energy in either a monopolar or a bipolar circuit through the tissue and the bodily fluids of an animal or human has a metallic electrically and thermally conductive electrode for connection to an electrosurgical generator proximally and for transmission of the electromagnetic electrosurgical energy to the tissue and the bodily fluids of the animal or human distally. A sheath of heat shrinkable fluorinated polymeric substance is an electrical and thermal insulator held about the electrode for preventing the flow of electromagnetic and thermal energy from the metallic electrically and thermally conductive electrode to the tissue and the bodily fluids. A smooth surface of the sheath contacts the tissue and the bodily fluids and has a low surface free energy. Openings through the sheath extend from the electrode to the surface for permitting the passage of energy.

  • Patent number: 5380320
    Abstract: An electrosurgical instrument has a conductive elongated member, a connector for connecting an external electrical power supply to the proximal end of the elongated member, an electrosurgical implement at the distal end of the elongated member, and an insulative parylene coating covering the elongated member. The thickness of the parylene coating is in the range of approximately 1 to 6 mil inches, and preferably 2 to 3.5 mil inches. In the preferred embodiment, the surfaces of the instrument that are to remain uncoated are first masked. The unmasked surfaces are roughened and then dipped in a liquid silicone. The parylene coating is then applied by vacuum vapor phase deposition and annealed. A parylene coating can also be applied to portions of the electrosurgical implement for insulation. A thin parylene coating can be applied to the blade of the instrument as a non-stick coating for easier cleaning.
