  • Patent number: 11975167
    Abstract: A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.

  • Patent number: 11971330
    Abstract: A leak detector is provided that is incorporated into the wheels of a moveable medical device and/or cart or cabinet therefor. By incorporating a leak detector into the wheels themselves of the movable medical device, the leak detector, despite movement of the medical device, is suitably located to locate leaks with respect to the medical device at all times and requires no additional setup. The leak detector can further be tested by and interface with the moveable medical device to ensure the leak detector is in working condition and provide a convenient interface for a user. Additionally, by using this technology on each of the multiple wheels of a moveable medical device, the detectable area may be bigger than a leak detector at only one location.

  • Patent number: 11911580
    Abstract: Devices, systems for localized delivery of a chemotherapy, hormonal therapy or targeted drug/biologic therapy to a target tissue area of an internal body organ of a patient. A catheter 10 forms a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin. The drug may saturate the target tissue area and pass therethrough into the lymphatic system or interstitial space, which may serve as a reservoir of the drug for continued therapeutic treatment after withdrawal of the catheter. The chamber is evacuated at the end of the treatment session.

  • Patent number: 11883087
    Abstract: Methods for treating a patient using therapeutic renal neuromodulation and associated devices, systems, and methods are disclosed herein. One aspect of the present technology is directed to methods including selectively neuromodulating afferent or efferent renal nerves. One or more measurable physiological parameters corresponding to systemic sympathetic overactivity or hyperactivity in the patient can thereby be reduced. Selectively neuromodulating afferent renal nerves can include inhibiting sympathetic neural activity in nerves proximate a renal pelvis. This can include, for example, neuromodulating via fluid within the renal pelvis. Selectively neuromodulating efferent renal nerves can include inhibiting sympathetic neural activity in nerves proximate a portion of a renal artery or a renal branch artery proximate a renal parenchyma. This can include, for example, neuromodulating via a therapeutic element within the portion of the renal artery or the renal branch artery.
