Means Or Method For Facilitating Removal Of Non Therapeutic Material From Body Patents (Class 604/540)
  • Patent number: 11141561
    Abstract: A urinary catheter is readily removed and replaced with a second urinary catheter without introducing foreign matter or contaminants into the bladder. The first urinary catheter includes an extra lumen that houses a sheath, which sheath seals the extra lumen from introduction of fluids. The sheath seals an opening hole at or near the tip of the catheter. After the sheath is extracted from the catheter, a guidewire is threaded through the extra lumen and into the patient's bladder. The first urinary catheter is withdrawn from the patient, leaving the guidewire in the patient. A second urinary catheter is inserted into the patient over the guidewire, with the guidewire present in the urine lumen of the second urinary catheter. The guidewire then is extracted from the patient. The second urinary catheter may also have an extra lumen and a sheath with a break-away seal so that the second urinary catheter may be removed and replaced in like manner.

  • Patent number: 10690655
    Abstract: A collector-analyzer apparatus for urine has a urine collecting tube joined with a urine receiving canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received or resident within the canister. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection between the urine tube and the urethra.

  • Patent number: 9050127
    Abstract: An atherectomy and thrombectomy system includes a catheter body extending between proximal and distal catheter portions. The catheter body includes an aspiration lumen extending therein. An atherectomy assembly is coupled with the distal catheter portion and includes a rotatable cutter. A thrombectomy assembly is coupled with the distal catheter portion. The thrombectomy assembly includes a jet body within the aspiration lumen, and inflow and outflow orifices extending through the catheter body and in communication with the aspiration lumen. In a thrombectomy configuration a cyclical flow is generated by the jet body through the outflow and inflow orifices to hydrodynamically abrade thrombus, the cyclical flow entrains thrombus and delivers thrombus into the aspiration lumen. In the atherectomy configuration the rotatable cutter cuts plaque into plaque particulate, and the cyclical flow of the thrombectomy assembly entrains the particulate and delivers the particulate into the aspiration lumen.

  • Patent number: 9039677
    Abstract: The present invention is directed to an apparatus and method for treating obesity. A tube is positioned that passes through a patient's abdominal wall into the upper digestive system of the patient. The patient is allowed to carry out his/her everyday affairs including ingesting food. After the patient has ingested food, the food is extracted by pumping it out of the upper digestive system through the tube. The present invention is less invasive than current surgical procedures for reducing weight and allows patients to live a normal and active lifestyle without experiencing adverse side effects.

  • Patent number: 9033955
    Abstract: A device for the treatment of pneumothorax especially in neonates, which facilitates the simple one-hand introduction of a catheter-sheathed stylet through the chest wall and which contains a one-way valve outside the chest for the stat evacuation of the intrathoracic air or fluid. The device is capable of secure fixation to the chest wall until deemed no longer needed at which point it is quickly removable. The thoracic cavity is entered by a stylet which is surrounded by a catheter, the catheter lumen continuous with that of a lumenized dome which communicates with at least one upper port and one-way valving. One port is configured to allow Luer-Lok suction in the event of pleural effusion or hemothorax.

    Abstract: An extracting device for diagnosis and treatment of diseases includes a tip equipped with a one-way liquid valve; a chamber equipped with a one-way air valve; and an elastic bulb for generating suctioning-pushing pressure when it is squeezed and released. When the user squeezes and releases the elastic bulb, the liquid will be drawn into the chamber through the tip. Additional fluidal material can enter into the bulb. After the liquid or mucus is drawn out, the body function such as nasal breath can be resumed. A specimen can be taken into the chamber through the tip and then transferred to a test tube for laboratory diagnosis. A new method of obtaining and removing body secretion is provided. No any form of electricity is needed. The parts can be easily disassembled for clean for repeated uses as a mucus extractor.

  • Publication number: 20150119864
    Abstract: Apparatus and associated methods for a wound valve assembly provide an annular space extending radially around a central portion of a valve, which valve acts to substantially relieve pressure build up in a thoracic cavity when applied to a thoracic wound. In an illustrative example, the valve assembly may form an annular space that extends radially in all directions around a check valve. In some examples, gasses and exudates may flow substantially radially and/or parallel to the patient's local body. Various embodiments may advantageously provide open fluid communication for the gasses and exudates escaping from the wound when the valve assembly is partially covered (e.g., body armor, clothing, blankets), or when the patient may be lying down on the side of the body with the wound, for example.

  • Patent number: 9017303
    Abstract: A selective-capacity collection and drainage device having a first collection container, a second collection chamber and a common inlet valve characterized by a capacity selector and a common outlet valve connecting to each collection chamber. The common inlet valve consists of a common inflow tube, which connects via tubing to the catheter where bodily fluids will enter the selective capacity chamber. The inlet valve has a capacity-selector located between the common inflow tube and the multi-chambered container, such that bodily fluids are directed by the capacity-selector into one or all of the collection chambers via the divided inflow tube. Each individual chamber of the multi-chambered container is connected at its base to the common outlet valve. The common outlet valve consists of a divided outflow tube on top, which connects to each collection chamber, and converges at an outflow valve.

  • Patent number: 9011365
    Abstract: This invention is a device and method for adjustably and reversibly reducing nutrient absorption from food passing through a person's gastrointestinal tract using an Adjustable Gastrointestinal Bifurcation (AGB) and a flow-control member. The Adjustable Gastrointestinal Bifurcation (AGB) includes: a first food-flow route (comprising a first branch of the AGB) through the person's gastrointestinal tract wherein there is normal absorption of nutrients from food; and a second food-flow route (comprising a second branch of the AGB) through the person's gastrointestinal tract wherein there is reduced absorption of nutrients from food. The flow-control member adjusts the types and/or amounts of food which are diverted through the second food-flow route versus the first food-flow route.
