  • Publication number: 20240009369
    Abstract: An endovascular implant for forming a fistula includes a body including a wall forming a lumen having a distal opening and a proximal opening. An anchor is coupled to a distal end of the body adjacent the distal opening. The anchor may include a first anchor extending from a first side of a distal end of the body, and a second, separate anchor may extending from a second side of the distal end of the body. A retriever may be coupled to a proximal end of the body adjacent the proximal opening.

  • Publication number: 20220280244
    Abstract: In one aspect, a system for endovascular treatment of a blood vessel includes a control unit, an ultrasound device, an actuator, and a catheter having a treatment portion. The ultrasound device is communicatively coupled to the control unit. The ultrasound device includes an ultrasound probe having a subject contact surface. The actuator is coupled to the ultrasound probe and is operable to move the subject contact surface of the ultrasound prove relative to a treatment zone of a subject. The control unit is configured to determine a position of the treatment portion of the catheter as the catheter is advanced through the blood vessel, and move the subject contact surface of the ultrasound probe relative to the treatment zone of the subject with the actuator to follow the position of the catheter as the catheter is advanced through the blood vessel.

  • Patent number: 11103339
    Abstract: A method of treating a patient includes providing an implantable vessel filter including a plurality of legs and center-post, inserting the filter into a delivery assembly, and deploying the filter at a desired location in a patient's body. One or more of the legs may have a hook at a distal end thereof and the center-post includes a grooved distal section to receive the hooks. The filter legs transition from a compressed configuration to an expanded configuration during deployment.

  • Patent number: 10512531
    Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.

  • Publication number: 20170189213
    Abstract: Apparatuses and methods for coating and/or loading a medical device with a therapeutic agent prior to or during the placement of the medical device within the patient's body. In one variation, the medical device is coated and/or loaded with a therapeutic agent while the device is positioned in a delivery apparatus. In another variation, the delivery apparatus comprises a reservoir for retaining a therapeutic agent. The user may release the therapeutic agent from the reservoir prior to or during the placement of the device to coat and/or load the device with the therapeutic agent.

  • Patent number: 8372109
    Abstract: An implantable vessel filter including an elongated body coupled proximally to a hub, and including a grooved distal section. A first set of legs coupled proximally to the hub have a first length, each of the first set of legs translating from a collapsed state in a filter compressed configuration to an extended state in a filter expanded configuration. A second set of legs coupled proximally to the hub have a second length longer than the first length, each of the second set of legs including a hook positioned at a distal end thereof, each of the second set of legs translating from a collapsed state in the filter compressed configuration to an extended state in the filter expanded configuration, each hook received in the grooved distal section in the filter compressed configuration and penetrating a wall of a vessel in the filter expanded configuration.
