Patent number: 11592132Abstract: The invention relates to a fluid coupling (1) with tolerance compensation for the flexible connection of two media-conducting elements. The invention was based on the object of improving a fluid coupling (1) of the described type in such a manner that the use of complicated latching systems for transport can be omitted. This object is achieved in that the fluid coupling (1) has at least one transport securing device (8, 12), by means of which a separation of the components (2, 3) of the fluid coupling (1) from one another prior to installation can be prevented.Type: GrantFiled: July 4, 2019Date of Patent: February 28, 2023Assignee: ContiTech MGW GmbHInventors: Axel Flach, Harald Kreidner, Klaus-Alexander Siegel

Publication number: 20230042304Abstract: Several embodiments and methods are described for draining a lymphatic system for therapeutic purposes. The lymphatic draining can be performed by removal of fluid from the lymphatic system via a needle, a catheter, an access port, a reservoir, a shunt, or a combination of these devices. The drainage devices can be configured for use during only a single procedure or for reoccurring procedures.Type: ApplicationFiled: January 15, 2021Publication date: February 9, 2023Applicant: NXT Biomedical, LLCInventors: Jeremy Koehler, Elliot Howard, Abubaker Khalifa, Joseph Passman, Glen Rabito, Stanton J.

Publication number: 20220257221Abstract: Low profile biopsy tools and methods that allow relatively large biopsy samples to be taken. The biopsy tools have a first configuration that allows for atraumatic navigation to a targeted lesion, and a second configuration in which a distal end of the biopsy tool expands to take a large tissue sample. The tissue sample may then be retracted into a sheath or other containment feature and removed at a reduced diameter. Also included is an anchored guidewire usable to practice method for navigating a biopsy tool to a targeted lesion after an endoscope has been removed.Type: ApplicationFiled: July 29, 2020Publication date: August 18, 2022Applicant: NXT Biomedical, LLCInventors: Stanton J.

Publication number: 20220176087Abstract: Devices and methods of treating fluid retention caused by congestive heart failure or other conditions resulting in edema, lymphoedema, or significant fluid retention (e.g., deep vein thrombosis, cellulitis, venous stasis insufficiency, or damage to the lymphatic network) are described. Specifically, a treatment device is used to create a passage or cannula between the lymphatic system (or other area of the body) and an external drainage device. This device can be only temporarily located in the patient or can be implanted within the patient for longer periods of time. The physician can safely and reliably remove excess fluid from the body via the device and optionally inject other treatment agents.Type: ApplicationFiled: February 24, 2022Publication date: June 9, 2022Applicant: NXT Biomedical, LLCInventors: Robert S.

Publication number: 20220142806Abstract: Renal and urine collection system interventions are provided that improve kidney function by manipulating pressures and/or infusing therapeutic agents in the renal pelvis of the kidney or kidneys. Setting a vacuum and/or infusing therapeutic agents in the renal pelvis results in increased glomerular filtration rate, general solute clearance, and free water excretion via the kidney through the urinary tract and is useful for treatment of CHF, ADHF, AKI, CKD, and many other conditions characterized by fluid overload by reducing fluid buildup. The fluid drawn from the renal pelvis or pelvises is delivered to an external or implanted reservoir or to the bladder using flow manipulation mechanism such as one-way valves, occlusion balloons, multi-lumen catheters, and other mechanisms. Pumps are provided for use in establishing the vacuum pressures that are either manual or motorized.Type: ApplicationFiled: May 18, 2020Publication date: May 12, 2022Applicant: NXT Biomedical, LLCInventors: Joseph Passman, Abubaker Khalifa, Stanton J.
