  • Publication number: 20190314129
    Abstract: An urethral compression apparatus is defined by a semi-cylindrical fenestrated dorsal hood that is worn dorsally on the penis and which is interconnected with a strap to a urethral compressor that is oriented ventrally to apply compressive pressure on the urethra to prevent urine leakage. The dorsal hood and the urethral compressor apply distributed pressure that prevents compromised venous and arterial circulation but eliminate incontinence. The device may be worn continually and is easily removed to allow voiding, then reattached. The fenestration in the dorsal hood (or plural fenestrations as the case may be) allows distribution of pressure to avoid venous and arterial blood flow interruption. The dorsal hood partially encircles the penile shaft and the urethral compressor is oriented ventrally and applies the desired pressure to the soft ventral tissues and the urethra.

  • Publication number: 20190269510
    Abstract: A delivery system facilitating retrieval of interventional device includes a sheath, an operation handle for driving the sheath to move, and a tube axially slidably engaging with the pusher section. The sheath includes a carrier section at a proximal end for surrounding the interventional device and a pusher section connected with the carrier section. Depending on different axial positions, the tube assumes an initial configuration in which a proximal end portion thereof is at a periphery of the pusher section, and an operation configuration in which the proximal end portion is held tightly around the carrier section and limits further expansion of the carrier section. The delivery system functions to hold the support frame tightly by surrounding the sheath with the axially movable tube, retrieving the support frame and preventing the support frame from falling off from a core shaft, thereby reducing risks in surgery and the mortality rate.

  • Publication number: 20190223934
    Abstract: This invention relates to a novel surgical device scalable to small dimensions for thermally-mediated treatments or thermoplasties of targeted tissue volumes. An exemplary embodiment is adapted for fusing, sealing or welding tissue. The instruments and techniques utilize a thermal energy delivery means, for example an electrical energy source, to instantly elevate the temperature of a biocompatible fluid media within an electrically insulated instrument portion. The altered media which may then be a gas is characterized by a (i) a high heat content, and (ii) a high exit velocity from the working end, both of which characteristics are controlled to hydrate tissue and at the same time denature proteins to fuse, seal, weld or cause any other thermally-mediated treatment of an engaged tissue volume—while causing limited collateral thermal damage and while totally eliminating electrical current flow the engaged tissue volume.

  • Patent number: 10328286
    Abstract: A beam shaping assembly for neutron capture therapy includes a beam inlet, a target having nuclear reaction with an incident proton beam from the beam inlet to produce neutrons forming a neutron beam, a moderator adjoining to the target, a reflector surrounding the moderator, a thermal neutron absorber adjoining to the moderator, a radiation shield arranged inside the beam shaping assembly and a beam outlet. The material of the moderator is subjected to a powder sintering process using a powder sintering device so as to change powders or a power compact into blocks. The reflector leads the neutrons deviated from the main axis back. The thermal neutron absorber is used for absorbing thermal neutrons so as to avoid overdosing in superficial normal tissue during therapy. The radiation shield is used for shielding leaking neutrons and photons so as to reduce dose of the normal tissue not exposed to irradiation.
