  • Patent number: 10561816
    Abstract: A device for interventional surgical or medical procedures is presented. The device is generally in the form of a balloon and is used to position itself or other working elements up against or through lumen walls in the body. The balloon is comprised of at least two materials of different elastic modulus, which allows for a flexible but relatively non-distensible, unfolding component of the balloon as well as an elastomeric, inflatable component of the balloon. The elastomeric component is fixedly attached to the flexible but relatively non-distensible component and together they form a pressure vessel that can be inflated within the lumens of the body.

  • Patent number: 10413441
    Abstract: The colostomy balloon plug has three parallel conduits with a combined charcoal and hydrophobic filter at one end of the largest central first conduit. The largest central first conduit is open at one end and has the combined charcoal and hydrophobic filter at its other end, for elimination of bowel gas. A shorter parallel second conduit terminates on one end in a first balloon and on a second end in a first one-way valve. A shortest parallel third conduit terminates on one end in a second balloon and on a second end in a second one-way valve. A syringe and extension conduit is selectively attached to the two one-way valves. Air, saline solution or sterilized water can be introduced from the syringe through the one-way valves of the extension conduit to inflate the two balloons about the largest central first conduit. The one-way valves prevent deflation of the balloons unless the shorter or shortest parallel conduits are cut to allow the fluid from the two balloons to exit and deflate the balloons.

  • Patent number: 10363358
    Abstract: The present disclosure relates to a PTA (percutaneous transluminal angioplasty) balloon catheter, preferably high pressure type, optionally introducible as an over the wire catheter. The catheter possess the attribute of injecting fluid to the treated site through a dedicated opening proximal to the balloon member, for introduction of fluids such as contrast enhancing material and/or medication. In some embodiments, a single lumen is used, at least in part, both for fluids transfer and dispersion (“infusion”) as well as for guide wire passage. In some such embodiments, a valve mechanism is used to sustain selective operability of the lumen so that fluids will disperse mostly or solely through the proximal dispersion opening rather than the guide wire distal exit opening.

  • Patent number: 10154850
    Abstract: A nasal balloon catheter and sponge unit is provided for stopping posterior epistaxis (nosebleed) in a quick and adjustable manner. The unit can be easily introduced into the bleeding nasal passage of a patient by a health care provider. Once inserted in the patient's nasal passage, the unit operates through inflation of a posterior balloon via a catheter, acting to stop the posterior bleed. In some embodiments, a second (anterior) balloon covers the inside of the nasal passage and is inflated subsequent to the inflation of the posterior balloon. Excess blood coming out of the nasal passage in the front is stopped by an absorbable sponge. If the packing is loose and blood escapes from the back of the nasal passage, a nut is utilized to squeeze the catheter against the nostril, hence more tightly pulling the posterior balloon to stop the blood.

  • Patent number: 9427233
    Abstract: The present invention provides, in certain embodiments, unique products and methods for occluding vascular vessels. Implantable devices useful in some inventive embodiments include at least two expandable occluding members, e.g., self-expandable sponge form devices, with an intermediate segment extending between the members. These devices are preferably compressible for placement in a delivery device lumen for delivery to a vascular vessel site. Upon deployment in the vessel, each of the members expands to occlude the vessel at a separate vessel location with the intermediate segment occupying space in the vessel between the two members. Optionally, the intermediate segment can be constructed to provide a hollow or other interior region for receiving one or more materials, for example, to receive an injectable fill material after one or both of the expandable members have been deployed.

  • Patent number: 9399121
    Abstract: A dilation catheter device and system for dilating an opening in a paranasal sinus and/or other passageways within the ear, nose or throat is disclosed. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, shaft markers are disposed on a shaft of the dilation catheter and have a light color to contrast with a dark color of the dilation catheter shaft. The high contrast between the markers and catheter shaft allows for easy viewing of the markers in low light and operation conditions.

  • Patent number: 9358042
    Abstract: Lead extraction is the removal of one or more leads from inside the heart utilizing a lead removal catheter having a tubular sheath that is placed in the blood vessel, either subclavian or femoral. The sheath of the lead removal catheter may accidentally tear or perforate the blood vessel as it is advanced over the lead toward the heart. Such an occurrence must be dealt with quickly to prevent harm to the patient or subject. An expandable member, such as a balloon, attached to the exterior of the sheath of a lead removal catheter can be deployed temporarily adjacent the perforation in the vessel wall. Inflation of the balloon not only stops (or substantially stops) the bleeding, but, upon inflation, the balloon may include one or more channels that allow blood to continue to flow through the channel(s) until the blood vessel perforation can be repaired.

  • Patent number: 8986241
    Abstract: Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.
