  • Publication number: 20230059358
    Abstract: A multi-lumen implantable device configured to deliver a therapeutic agent to a selected portion of a blood vessel is disclosed. As one example, an implantable device includes a first lumen configured to flow blood from an upstream end to a downstream end of the device when implanted in a blood vessel; a second lumen fluidly separated from the first lumen and configured for introducing a therapeutic agent to a selected, first portion of a wall of the blood vessel, between the upstream end and the downstream end of the device; and at least one sealing member configured to block the therapeutic agent from entering a second portion of the wall of the blood vessel, between the upstream end and the downstream end of the device.

  • Patent number: 11559055
    Abstract: In one representative embodiment, a method of perfusing organs in a patient's body is provided. The method comprises isolating the visceral arteries and the visceral veins from blood circulating through the patient's heart and perfusing the visceral arteries, the visceral veins, and the abdominal organs with a perfusion fluid that is fluidly separated from the blood circulating through the patient's heart. While the visceral arteries and the visceral veins are isolated, and the visceral arteries, the visceral veins, and the abdominal organs are being perfused, the patient's blood is allowed to continue to circulate through the heart.

  • Publication number: 20210052363
    Abstract: Disclosed are implantable tubular devices having a fenestration in a wall of the tubular device and a conductive coil positioned around the fenestration, such that the coil is operable to generate a magnetic field when electrical current flows through the coil. The magnetic field can be used to draw a ferrous or magnetically tipped guidewire or other device to and through the fenestration. In the example of a fenestrated endovascular graft, the coil can be used to draw a guidewire out through a fenestration into a branch blood vessel, such that the guidewire can be used to deliver a branch of the graft through the fenestration into the branch vessel. A power source can be contained in a nosecone.

  • Publication number: 20190374226
    Abstract: The present disclosure concerns embodiments of an implantable perfusion device that can be implanted in an injured blood vessel to control bleeding without occluding the vessel. In one specific implementation, the perfusion device can be implanted percutaneously into a patient's descending aorta to control bleeding at the site of a ruptured portion of the aorta (known as torso hemorrhage) while still allowing for the antegrade flow of blood from a location upstream of the ruptured portion of the aorta to a location downstream of the ruptured portion of the aorta. The perfusion device can be left inside the patient as the patient is transported to a medical facility where the injury can be repaired. Following repair of the vessel, the perfusion device can be withdrawn from the patient.
