  • Patent number: 12357767
    Abstract: A method for visually indicating that a door of a drug delivery device is open is described. A closing force to move the door is received. Then, it is detected that the door is not closed. A biasing element pushes the door to a perceptibly open position with an opening force when the door reaches the last 30 degrees of rotation of toward closure or when the door reaches the last 30% of range of movement during the rotation of the door. The perceptibly open position of the door is indicated relative to a drug delivery device housing.

  • Patent number: 12329913
    Abstract: Improved urinary catheters are described. One example urinary catheter includes a catheter shaft with an internal lumen, extending between a distal discharge opening and a proximal drainage opening, arranged at a proximal tip of the catheter shaft. An overcoat layer encircles a portion of the catheter shaft, forming a closed deformable fluid filled cavity intermediate the overcoat layer and the outer surface of the shaft. The overcoat layer is elastically deformable to allow for movement of the fluid within the cavity during deployment. At least a portion at the proximal end is arranged to be compressed to a smaller diameter during insertion, and upon continued insertion of the catheter shaft through the urethra into at least the bladder neck, arranged to expand back toward a greater diameter, as the fluid is caused to flow toward the proximal end of the fluid filled cavity.

  • Patent number: 12311092
    Abstract: A method of producing an arteriovenous (AV) fistula includes producing an anastomosis between a primary blood vessel (e.g., a vein) and a secondary blood vessel (e.g., an artery). A collateral (or competing) blood vessel in fluid communication with one of the primary blood vessel or the secondary blood vessel is identified. A reversible flow restrictor is then applied to the collateral blood vessel to reduce a blood flow rate through the collateral blood vessel. In some embodiments, the anastomosis can be produced percutaneously. In some embodiments, the reversible flow restriction (or a portion thereof) can be removed from the collateral blood vessel. In other embodiments, the reversible flow restriction (or a portion thereof) can be adjusted to allow increased blood flow therethrough while within the collateral blood vessel.

  • Patent number: 12256943
    Abstract: Embodiments of the present invention are directed to devices, systems and methods adapted for implementing intermittent displacement of blood to mitigate peripheral nerve neuropathy such as that induced by chemotherapeutic agents (i.e., chemotherapy-induced neuropathy (CIN)) that are administered to a patient. Such devices, systems and methods advantageously provide for precise, uniform and controlled blood flow occluding (and optionally blood displacing) compression along irregular surfaces of an appendage of a patient. Such precise, uniform and controlled blood occluding compression is imparted upon the epidermal and dermis skin layers within the aforementioned areas of a patient's extremities to decrease the time that free nerve endings located in the epidermal and encapsulated nerve endings located in the dermis skin layers are exposed to nerve damaging chemotherapy chemicals, thereby substantially decreasing CIN caused by prolonged exposure to such chemicals.
