  • Patent number: 11571511
    Abstract: An insertion mechanism for a drug delivery device. The insertion mechanism includes a proximal end, a distal end, a first opening disposed near the proximal end, and a second opening disposed in the distal end. A needle or cannula assembly is disposed within a housing and has a base with a proximal surface and a distal surface and a needle or cannula coupled to the distal surface. A retraction member is disposed within the housing to maintain the needle or cannula assembly in a retracted position before movement to an extended position, the retraction member in contact with the base. Upon supplying pressure through the first opening until an amount of pressure P1 applies an application force to the proximal surface of the base that surpasses a resistive force of the retraction member, the needle or cannula assembly is moved from the retracted position to the extended position.

  • Patent number: 11547836
    Abstract: A coaxial stabilizing and sealing catheter provides increased support to a guide catheter that is seated in an ostium of a branch artery by extending through and out of a distal end of the guide catheter and anchoring in position within the branch artery that is being treated. The stabilizing and sealing catheter includes, as part of a relatively flexible distal section, a balloon that locks a distal end of the stabilizing and sealing catheter in place to provide support to therapeutic devices that are introduced and further seals the branch artery to prevent blood from entering the branch artery. A sealing cuff at a proximal end of the stabilizing and sealing catheter provides a seal between an exterior of the stabilizing and sealing catheter and an interior of the guide catheter. In addition, a fixing mechanism is utilized to lock the guide catheter in place to exchange therapeutic devices.

  • Patent number: 11511073
    Abstract: One embodiment is a medical device with a flexibly deformable external hose. The external hose includes multiple openings, at least one of them arranged in a first end of the external hose. It includes a flexible internal hose, which is arranged on the inside of the external hose. The internal hose, in an expanded state, has an external diameter that is at least equal to the internal diameter of the external hose, closing the openings of the external hose. The external diameter of the internal hose can be transitioned from the expanded state into a radially contracted state, exposing the openings. A connection firmly connects the external hose and the internal hose on the first end of the external hose, and closes them in fluid-tight manner. A connector supplies the fluid into the intervening space between the external and the internal hose.

  • Patent number: 11504519
    Abstract: The present teachings may generally include a sealing device disposed within a connector (e.g., a patient connector) at an end of catheter tubing, where the sealing device is structurally configured to form a releasable seal for the catheter tubing. That is, when unengaged with a contact portion of another connector or device, the sealing device may be disposed in a first position establishing the seal. Specifically, a channel disposed through a body of the sealing device may be obstructed when in the first position. However, through predetermined engagement with the contact portion of another connector or device, the sealing device may be moved (e.g., rotated) to a second position to establish a fluid pathway through the channel. And, when the predetermined engagement is removed, the sealing device may be structurally configured to automatically move back into the first position to reestablish the seal for the catheter tubing.
