  • Patent number: 12138186
    Abstract: This document describes devices, systems, and methods for automatically deploying intravascular devices. For example, this document describes devices, systems, and methods for automatically deploying and controlling intravascular catheter-based devices for treating catastrophic bleeding from large and medium size vessels such as, but not limited to, the aorta or iliac arteries. In some embodiments, an operator/care giver will simply press the system against the patient's body proximate to a desired site of insertion, or will attach the system to the patient proximate to the desired site of insertion. The operator will then activate the system. Thereafter, the system will use built in imaging (e.g., ultrasound) to locate a proper insertion point and then deploy an access needle to attain vascular access. With that, the system will then automatically insert the intravascular device into the patient.

  • Publication number: 20240130879
    Abstract: Some implementations of an endovascular device include a stent graft with an expandable tubular metallic frame and a covering material disposed on at least a portion of the metallic frame. The stent graft defines a lumen therethrough. In a particular embodiment, a first balloon is disposed around an outer periphery of the stent graft, a second balloon is disposed around the outer periphery of the stent graft and spaced apart from the first balloon, and a third balloon is disposed within the stent graft lumen between the first balloon and the second balloon. The third balloon can be inflated to fully or partially occlude the lumen. The first and second balloons can be individually inflated to fully or partially shunt blood flow from a blood vessel through the stent graft. In some embodiments, sensors and an automated control unit are included to automate the operations of the endovascular device.

  • Publication number: 20240108376
    Abstract: An intravascular cutting device described herein uses high-pressure water, saline, or other fluid to cut tissue and other materials including but not limited to calcified tissue, stents, stent grafts, and other devices. In some embodiments, the cutting device includes a working end that has a nozzle with a hole to allow the release of a high-pressure fluid jet. Opposite of the nozzle is a catch plate or deflector anvil that prevents the fluid jet from cutting healthy tissue. The device user will place the item to be cut between the nozzle and catch plate and then advance the device along the item to be cut as the fluid jet is activated, thus cutting the object as it advances.

  • Publication number: 20210338412
    Abstract: Elastomeric bypass grafts (EBG) described herein can be pre-stretched and are able to accommodate limb flexion-induced or organ-induced deformations without producing excessive tortuosity or stresses. In comparison to known grafts, EBGs demonstrate significantly less tortuosity when used for lower extremity repair during limb flexion, and improved flow patterns within the grafts. Longitudinally pre-stretched EBGs described herein improve hemodynamics and may produce better healing responses in the harsh mechanical environment of the lower limbs, compared to known grafts.

  • Patent number: 10779851
    Abstract: A catheter mounted arterial surgical tool has a body with a fluid jet prong extending from a distal end of the body along a prong axis that is parallel to and laterally offset from a body axis. A fluid passage extends through the fluid jet prong to an outlet that points laterally relative to the prong axis. A deflector anvil extends from the distal end of the body along a deflector axis that is parallel to and offset from the body axis. The deflector anvil has a face that faces toward the fluid jet prong and is impinged by a fluid jet discharged from the outlet. A pair of guide wire holes extend from the proximal to the distal end of the body parallel to the body axis for receiving guide wires to enable the body to slide along the guide wires.
