  • Patent number: 10945789
    Abstract: The method of treating benign prostatic hyperplasia comprises trans-perineally introducing at least one energy delivery device through a perineal area of the patient in a first position in a prostate of the patient. Once the energy delivery device has been introduced, energy is delivered through the delivery device to a volume of tissue of the prostate, until the volume is vaporized or sublimated and a cavity is formed in the prostate tissue. The energy delivery device can then be removed from the prostate. Vaporization of adenomatous tissue provides immediate relieve of the urethra compression.

  • Patent number: 10670162
    Abstract: A fluid bypass valve includes a valve member disposed within a valve chamber of a housing. A temperature based actuating mechanism moves the valve member between a first position and a second position in response to a temperature change. A temporary flow control device undergoes a one-time only shape change between a first shape and a second shape. The temporary flow control device enables fluid communication between a first port and a second port when exhibiting the first shape, and does not enable fluid communication between the first port and the second port when exhibiting the second shape. The temporary flow control device exhibits the first shape when having an initial temperature less than or equal to a second pre-defined temperature, and exhibits the second shape in response to a first heating of the temporary flow control device to a temperature that is greater than the second pre-defined temperature.

  • Patent number: 6962208
    Abstract: A pendant sprinkler head includes a sprinkler body formed with a central orifice, and a sealing member positioned within the orifice and in sealing engagement with the inlet. A deflector assembly is at least partially positioned within the orifice and includes an annular ring having a pair of attachment arms secured to a deflector plate positioned in proximity to, or partially within the outlet. A retaining ring positioned within the orifice acts as a stop, preventing the annular ring from being expelled from the orifice. According to another aspect of the invention, a pendent sprinkler head includes a sprinkler body and a body extension connected to the body. A deflector plate is formed with a plurality of support members received by a retaining ring positioned in proximity to the bottom of the sprinkler body, and within the body extension. The body extension is configured to capture the retaining ring upon activation, enabling the deflector plate to depend below the body extension.

  • Patent number: 6868917
    Abstract: A low pressure, early suppression fast response sprinkler includes a generally tubular body having an inlet ends, an opposing discharge end and an internal passageway extending between the inlet and discharge ends with a K factor greater than 16 where the K factor equals the flow of water in gallons per minute through the internal passageway divided by the square root of the pressure of water fed into the tubular body in pounds per square inch gauge. A deflector is coupled with the tubular body and spaced from and generally aligned with the discharge end of the internal passageway so as to be impacted by a flow of water issuing in a column from the discharge end upon activation of the sprinkler. The deflector is configured and positioned to deflect the flow of water generally radially outwardly all around the sprinkler.

  • Patent number: 6715561
    Abstract: A vacuum dry sprinkler system includes a sprinkler head formed with a body having a central orifice through which fire extinguishing fluid is expelled through an outlet end. A yoke, attached to the exterior surface of the sprinkler body, extends beyond the outlet end of the sprinkler body and is connected at its apex to a deflector. A thermally sensitive trigger member is coupled to the yoke and the outlet end of the sprinkler head. The sprinkler body carries an expulsion assembly which includes an expulsion member and a thrust member. In response to a fire, the expulsion member of the expulsion assembly overcomes the vacuum force and expels the sealing assembly out of the outlet end of the sprinkler body, while the thrust member laterally thrusts the sealing member out of the water trajectory path, and thus, prevents the sealing assembly from reseating on the outlet of the sprinkler head.

  • Patent number: 6152236
    Abstract: A combined trigger and concealing device for an automatic sprinkler head comprises a first plate attached to a second plate by a heat fusible material in a partially overlapping manner. Each plate is formed with an aperture which receives an actuator depending from the bottom of the sprinkler head. The trigger device depends a preselected distance from the bottom of the sprinkler head body and has an outer dimension which causes the trigger device to conceal the internal components of the sprinkler head from view. An annulus defined between the periphery of the device and the bottom of the sprinkler head permits heat energy to be received by the inner surface of the trigger device. Conduction of heat energy from both the inner and outer surface of the trigger device permits the heat fusible material to be expeditiously raised to the preselected separation temperature. This uniform thermal conduction minimizes the response time of the automatic sprinkler head while maintaining a highly aesthetic appearance.

  • Patent number: 5669449
    Abstract: Directional sprinklers include a sprinkler body with a water directing structure configured to direct water passing from an outlet of the sprinkler body in one or more distinct and different directions. Water directing structures are disclosed in the form of deflectors having one or two separate water directing channels and hollow heads having at least two separate nozzles facing in two distinct and different directions. The channels and nozzles can be configured to direct water in diametrically opposing directions, mutually perpendicular directions or at any other desired orientation with respect to one another and to direct the water radially outwardly from the centerline of the sprinkler body outlet or at any predetermined transverse angle to that centerline. The throw of each channel and nozzle is longer than it is wide so that water is discharged over a generally rectangular or elliptical area in each direction.

Described deflectors for concealed sprinklers are circular with slots extending axially and radially through inwardly towards the center of the deflector from the circular perimeter. Such deflectors include a central curved protrusion extending back towards the outlet to spread the water column over the deflecting structure and a surrounding planar annular area of the structure.

  • Patent number: 5628367
    Abstract: A sprinkler head includes a powdered metal base including external threads for threadably engaging a water pipe, and a stamped metal frame attached to the base. The base defines a passageway for receiving water from the water pipe and an opening to the passageway. The powdered metal base is infiltrated with copper or vacuum infiltrated anaerobic resin to provide a hydrostatically leak tight composition capable of withstanding 700 psi. A deflector is attached to the frame for distributing water dispensed from the opening. A circular plate or circular spring sealingly covers the opening, and a pip is engaged with the frame creating a space therebetween. A frangible bulb is positioned in the space between the Belleville spring. The frangible bulb is made of a temperature-sensitive material that fractures at a predetermined temperature and thus allows water pressure from water in the water pipe to unseat the spring and thus spray water.
