  • 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: 10327759
    Abstract: A multiple-firing crimp device comprises crimps, a shaft, a crimp movement assembly, and a snare. Each crimp has an internal hollow. The shaft has a distal crimping location, an exterior surface, and an interior with the clips stacked therein, the crimps moving therein along a longitudinal axis. The shaft defines a lateral opening proximal to the crimping location and communicates the interior to the environment outside the exterior surface. The crimp movement assembly within the shaft delivers the first crimp to the distal crimping location by moving the first crimp longitudinally from a first proximal position into the distal crimping location and returning to a second proximal position without the first crimp. The snare pulls at least one cord from distal of the first crimp through the first crimp and through a portion of the shaft and out the side of the shaft through the lateral opening.

  • Patent number: 10258354
    Abstract: A balloon suction catheter may be used to remove clots and increase blood flow to obstructed vessels such as a cerebral artery in a stroke patient. The catheter may be used to apply suction on the clot while providing flow arrest, embolic protection, and optionally flow reversal. The same catheter may also be used to provide for a flow modulation procedure known as post-conditioning to potentially reduce any damage from the sudden reintroduction of blood flow reperfusion injury.

  • Patent number: 10188412
    Abstract: A surgical snare is provided having an operating wire and an outer sheath having a lumen extending therethrough, wherein the operating wire is disposed within the lumen and is longitudinally movable within the lumen. The surgical snare also has a first locking member attached to the operating wire and a second locking member attached to the outer sheath. The first locking member is frictionally engageable with the second locking member by sliding the outer sheath longitudinally along the operating wire until the first locking member contacts the second locking member. The operating wire is prevented from moving longitudinally with respect to the outer sheath when the first locking member is frictionally engaged with the second locking member.

  • Patent number: 10058644
    Abstract: Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

  • Patent number: 9925353
    Abstract: A dual lumen cannula includes a first tube defining a return lumen and having a proximal end, a mid-portion and a distal end, wherein the distal end includes a return aperture. A second tube is coaxial with the first tube and has a proximal end and a distal end, wherein the distal end of the second tube is fixedly attached to the mid-portion of the first tube and wherein the distal end of the second tube includes a drainage aperture. A drainage lumen is defined by a space between the first tube and the second tube. A connector is attached to the proximal end of the second tube. The connector includes a reservoir for receiving a fluid from the proximal end of the second tube. The first tube extends through the connector and does not attach directly with the second tube at the connector, and the first tube remains substantially coaxial with the second tube throughout a length of the second tube.

  • Patent number: 9907889
    Abstract: Illustrative embodiments of new and useful systems and methods for reduced-pressure therapy are described. One example embodiment is a manually-actuated pump for applying reduced-pressure therapy. The pump generally comprises a charging chamber, a regulated chamber, and a regulator passage between the charging chamber and the regulated chamber. A valve body controls fluid communication through the regulator passage, and a regulator spring may be engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure. The regulator passage may have a bore size adapted deflect the valve body to cause an audible indication of a leak.

  • Patent number: 9642991
    Abstract: Systems and methods are provided for performing a medical procedure within a patient's body that involves a thoracic duct including an ostium communicating with the patient's venous system. A distal end of a catheter is introduced through the patient's venous system into a body lumen adjacent the ostium of the thoracic duct. An expandable member on the distal end of the tubular may be expanded adjacent the ostium, e.g., within the body lumen or the thoracic duct itself, and used to isolate the thoracic duct from the body lumen, whereupon a medical procedure may be performed via the thoracic duct. For example, lymphatic fluid may be removed from the thoracic duct through a lumen of the tubular member and/or one or more agents may be introduced into the thoracic duct through the tubular member.
