  • Patent number: 11478269
    Abstract: Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.

  • Patent number: 10849672
    Abstract: Liners for cryogenic treatment systems are described where a cryogenic fluid or gas may be introduced into a liner expanded within a body lumen such as the uterine cavity. The liner may be intentionally sized to be substantially larger than the typical size of the uterine cavity, e.g., 1.2 times (or more), greater than the size of the uterine cavity into which the liner is inserted. Because the liner is sized intentionally larger than the body lumen to be treated, the liner may never fully expand when deployed. But even with folds or portions of the liner being folded upon itself, the liner may remain sufficiently supple such that the resulting uncontrolled folds allow for complete conformance of the liner against the anatomy of the contacted tissue.

    Abstract: Filtration systems with integrated filter element(s) forming portions of the wall of the filtration catheter are disclosed. The filtration catheters disclosed herein are designed to be used alone or in conjunction with another filter device to provide embolic protection of both carotid arteries. Occlusive element such as balloon is placed on the exterior of the filtration catheter to redirect blood flow in the vessels during the filtration process as well as to help anchor the filtration catheter inside the vessel. The integrated filter element(s) does not require collapsing thus significantly reduces the complexity of the filtration system retrieval process and the chances of releasing emboli back into the blood stream. The compact design of the filtration systems makes them particularly suitable for embolic protection during endovascular procedures on or close to the heart.

  • Patent number: 10363358
    Abstract: The present disclosure relates to a PTA (percutaneous transluminal angioplasty) balloon catheter, preferably high pressure type, optionally introducible as an over the wire catheter. The catheter possess the attribute of injecting fluid to the treated site through a dedicated opening proximal to the balloon member, for introduction of fluids such as contrast enhancing material and/or medication. In some embodiments, a single lumen is used, at least in part, both for fluids transfer and dispersion (“infusion”) as well as for guide wire passage. In some such embodiments, a valve mechanism is used to sustain selective operability of the lumen so that fluids will disperse mostly or solely through the proximal dispersion opening rather than the guide wire distal exit opening.

  • Patent number: 10285935
    Abstract: Most spinal cord therapies are administered systemically, with only a small portion of the therapeutic reaching the spinal cord. A novel method for delivering therapeutics directly to the spinal cord is provided. The method uses a dual balloon catheter to isolate the microvasculature around a region of the spinal cord. Once isolated, one or more therapeutics are delivered directly to the spinal cord blood supply. This allows for smaller, safer therapeutic dose to be utilized.

  • Patent number: 10179029
    Abstract: A method of performing denervation with a cooled microwave denervation catheter assembly includes advancing a catheter body over a guide wire in a body lumen of a patient to a treatment location adjacent targeted nerves, with the guide wire being located in an interior lumen of the catheter body, inflating the balloon with cooling fluid to contact a wall of the body lumen of the patient, removing the guide wire from the interior lumen of the catheter body, and inserting a microwave antenna catheter into the interior lumen of the catheter body, so that denervation treatment may be performed by simultaneously circulating cooling fluid in the balloon and supplying power to the microwave antenna, to cause the targeted nerves to be heated to a temperature sufficient to cause thermal damage while the wall of the body lumen is maintained at a temperature where thermal damage does not occur.

  • Patent number: 10154850
    Abstract: A nasal balloon catheter and sponge unit is provided for stopping posterior epistaxis (nosebleed) in a quick and adjustable manner. The unit can be easily introduced into the bleeding nasal passage of a patient by a health care provider. Once inserted in the patient's nasal passage, the unit operates through inflation of a posterior balloon via a catheter, acting to stop the posterior bleed. In some embodiments, a second (anterior) balloon covers the inside of the nasal passage and is inflated subsequent to the inflation of the posterior balloon. Excess blood coming out of the nasal passage in the front is stopped by an absorbable sponge. If the packing is loose and blood escapes from the back of the nasal passage, a nut is utilized to squeeze the catheter against the nostril, hence more tightly pulling the posterior balloon to stop the blood.

  • Patent number: 10029071
    Abstract: A urinary catheter has a body and an outer layer surrounding at least a portion of the body. The structure of the body is varied and non-uniform so as to impart a varying flexibility along the length of the catheter. The frame may be injection molded, while the outer layer may be extruded. The frame may also, or alternatively, have selected regions or portions that include planar or spiral cuts or a coiled filament or corrugations or a multifilament braid or weave or mesh to impart a desired flexibility profile. The flexibility profile of a male urinary catheter may include alternating rigid and flexible regions, with proximal and distal rigid regions being configured to be positioned within the bladder and penis, with two flexible regions separated by a rigid region positioned between the penis and bladder when the catheter is deployed within a male urethra.
