  • Patent number: 9669193
    Abstract: A safety balloon catheter includes a flexible, multi-lumen balloon catheter and a hollow barbell-shaped stretch valve. The balloon catheter has a proximal catheter end, a balloon defining a balloon interior to be inflated with an inflation fluid, a hollow inflation lumen extending through the catheter to the balloon interior and shaped to convey the inflation fluid to and from the balloon interior, and a hollow second lumen parallel to the inflation lumen; and a balloon drainage port fluidically connecting the balloon interior to the second lumen. The stretch valve is shaped to permit a fluid to pass therethrough and positioned in the second lumen to at least partially slide therein such that, in a steady state, a distal barbell end of the stretch valve prevents the inflation fluid from passing through the drainage port and, in an actuated state, the distal barbell end slides within the second lumen to permit the inflation fluid to pass through the drainage port and into the second lumen.

  • Patent number: 9642992
    Abstract: A method for manufacturing a safety catheter includes a flexible, multi-lumen shaft having a drain lumen draining fluid adjacent a distal tip of the shaft out a proximal drain end of the shaft and an inflation lumen. A hollow balloon portion has an inflation port fluidically connecting the inflation lumen to the balloon interior to inflate the balloon outwardly larger than a diameter of the shaft. The drain lumen is fluidically connected to the balloon interior by a drainage port. A hollow stretch valve in the drain lumen prevents fluid from passing through the drainage port in a steady state and permits fluid to pass therethrough in a stretched state when the shaft is stretched. Distal of a proximal end of the stretch valve, the shaft has a stretching extent that is relatively more stretchable than at least a portion of the shaft that is proximal of the stretching extent.

  • Publication number: 20170087364
    Abstract: An electrostimulation device includes a computer generating an electrostimulation generator control signal and outputting a music signal, a transcutaneous electrostimulation generator, an electronic signal conduit, and an electrode coupler. The generator receives the generator control signal and the music signal, generates a nerve electrostimulation signal dependent upon the generator control signal, and outputs the nerve electrostimulation signal at the stimulation output and the music signal at an audio output. The coupler fits in an ear canal, has a speaker connected to the audio output to output the music signal into the ear canal when worn, and has electrostimulation electrodes conductively connected to the stimulation output through the electronic signal conduit to receive the nerve electrostimulation signal and positioned to contact tissue within the canal to transcutaneously apply the nerve electrostimulation signal thereto.

  • Publication number: 20150360030
    Abstract: A transcutaneous electrostimulation device includes an electrostimulation generator providing at an output a nerve electro stimulation signal, an electronic signal conduit conductively connected to the output of the generator, and an electrode coupler shaped to form fit an ear canal of a human ear and having at least one electrostimulation electrode. The electrode is conductively connected to the electronic signal conduit to receive the nerve electrostimulation signal and is positioned at the electrode coupler to contact tissue within an ear canal and apply the nerve electrostimulation signal to the tissue transcutaneously. An audio source outputs audio signals. The electrode coupler has a speaker receiving the audio signals for output into the ear canal when the electrode coupler is worn. The generator sends the nerve electrostimulation signal to the electrode coupler while the audio signals are output. The generator modulates the nerve electrostimulation signal based upon the audio signals.

    Abstract: A cryoprotective device includes a hollow cryoprotective probe having a distal tip, a removable obturator, and at least one integral temperature sensor monitoring temperature at least adjacent the distal tip. An injector is able to inject a cyroprotective substance (CPS) through the cryoprotective probe and out the distal tip when the obturator is removed.

  • Publication number: 20150282697
    Abstract: To perform pelvic surgery, a directionally illuminating balloon catheter enters a bladder. The catheter has a multi-lumen shaft. The balloon defines an interior fluidically connected to a balloon inflation lumen and is inflated therethrough. The balloon comprises a light source, a light-radiating surface adjacent the shaft-balloon junction, and a substantially opaque surface disposed at a portion of the balloon other than the light-radiating surface such that the integrated light source illuminates a distal half of the environment outside the balloon. The balloon is inflated while in the bladder. Light from the light source is directed out through the light-radiating surface to illuminate at least a portion of a procedure area opposite the bladder-prostate junction. With the light illuminating the portion of the procedure area, at least a portion of a pelvic surgery is performed at the portion of the procedure area.
