  • Publication number: 20230070042
    Abstract: The bypass syringe is used in combination with an expandable or inflatable bladder or balloon that is circumferentially wrapped around a patient designed to reduce bleeding from a skin insertion wound site and a vascular wound site after a vascular intervention or surgical procedure is performed. The bypass syringe is designed to pre-inflate the balloon, allow the balloon to relax based on how tightly the band is wrapped around the patient, and then be inflated with a volumetric amount of fluid. The bypass syringe's pre-inflation step will reduce complications caused by variabilities in band securement or tightness. A pre-inflation step combined with a venting of excess air step or controlled pressure inflation steps will absorb/take up/consume excess space caused by variability in band securement and help to reduce complication caused by securement variability.

  • Patent number: 11554137
    Abstract: A composition and method useful in promoting healing of a bleeding wound site. The composition preferably includes a substantially anhydrous acid form of a cation exchange resin, which when applied over blood, provides an antimicrobial against planktonic microorganisms and biofilms in the wound. The resin is also capable, when applied in sufficient quantities, of providing a continuing and persistent antimicrobial against planktonic microorganisms and biofilms through dehydration and ion exchange with cations present in the blood and other body fluids. When the resin has a concentration of at least 26 mg/ml, it provides a >3 log reduction in biological activity of MRSA, MRSE and Pseudomonas aeruginosa.

  • Publication number: 20220330949
    Abstract: This device is a combination of an expandable or inflatable bladder or balloon in conjunction with a rigid or semi-rigid skin contact surface or structure to reduce bleeding from a skin insertion wound site and a vascular wound site after a vascular intervention or surgical procedure is performed. The device may be held in contact or close contact with the skin by a circumferential band, a clamp or other mechanism and provides a more consistent and uniform surface area contact and compression force. The contact surface or foot provides a uniform surface area contact as compared to the ever-changing contact surface area from an inflatable bladder.

  • Publication number: 20220190355
    Abstract: A typical fuel cell device that incorporates an anodic hydrogen splitting catalyst, with an electrolytic separator and a cathodic oxidant is provided. In particular, a fuel cell having a separator that can be kept in a dry state because the oxides in the anion section of the fuel cell will combine with the split hydrogen to create water to wet the separator. Additionally, the cathode can be exchanged to allow for reuse of the more expensive anode material.

  • Publication number: 20190343536
    Abstract: An air pressure-controlled inflatable compression device designed to be worn around the wrist to supply sufficient compression to control bleeding from an arteriotomy in the radial artery, while allowing blood to flow through the radial artery from the heart to the hand is provided. The device contains a bladder with a controlled inflation mechanism and a pressure sensor or indicator. The desired inflation pressure will be determined based on the blood pressure of the patient. The bladder pressure may be determined by a clinician based on the patient's vital statistics or the device may index the pressure using a pump and valve based on an electronic blood pressure sensor and a microprocessor controller. The length of time that the band compresses the artery will be determined by a clinician or microprocessor controlled.

  • Patent number: 10076319
    Abstract: This invention is directed to devices and methods for improving wound closures produced during endoscopic surgery. These methods are directed to delivering and applying a quantity of hemostatic agents in either powder, solid, liquid, or gel form onto an open wound produced e.g., by polyp removal, followed by the application of pressure. The method is implemented preferably using existing endoscopic equipment; however, modifications to existing endoscopic insertion tubes, application and tamping devices and endoscopic clips deployed from the distal end of the insertion tube during endoscopic surgery are also within the scope of this invention.

  • Patent number: 9877728
    Abstract: A hemostatic tablet preferably including potassium ferrate and a cation ion exchange resin pressure formed into a tablet for delivery to a bleeding wound. The tablet improves the rate of adhesion to a bleeding wound surface, and allows a significantly greater and more uniform pressure to be exerted by manual compression of the tablet on the wound site, as compared to that of a thin layer of scattered hemostatic powder. After the seal is formed from the interaction of blood or exudates with the immediate contacting surface of the tablet, the bulk of the unused tablet easily delaminates from the seal making clean up facile. If the unused portion of the tablet is not removed from the wound site, a reservoir of hemostatic dressing stops further bleeding and to provide antimicrobial protection and healing. The tablet may be applied to any surface orientation and take any shape and thickness possible.

  • Patent number: 9472812
    Abstract: An electrical cell and method for generating electrical power are disclosed for producing electrical energy from a gas such as hydrogen and isotopes thereof. The electrical cell comprises an ionizing material located within an interior volume of a housing for absorbing the gas and separating ions and electrons. An electron collector receives electrons generated by the ionizing material. An insulator material within the housing inhibits electrons from entering into an ion collector while allowing the gas and the ions to pass to the ion collector for generating electrical voltage between the electron collector and the ion collector.

  • Publication number: 20160206298
    Abstract: A combination radial arm band and hemostatic material preferably including potassium ferrate and a cation ion exchange resin in powder or granular form (WOUNDSEAL) or formed into a solid tablet (STATSEAL) and having improved topical effectiveness in the arresting of blood flow from a puncture wound into the radial artery made during transradial diagnostic or interventional catheterization procedures. The combination reduces time and pressure needed to achieve hemostasis and decreases arterial damage as compared to use of a radial arm band alone. In one aspect of this disclosure, careful limitation of applied force and time of applied force against the STATSEAL tablet reduces likelihood of harm to the radial artery while minimizing time to achieve hemostasis.
