  • Publication number: 20210204971
    Abstract: Systems and methods for creating autologous monocuspid and bicuspid valves can include a catheter having a single expandable element or a double expandable element. Once the leaflets of the valve are created, various techniques can be used to fix the leaflets to the vessel wall or to each other, including clips, tissue anchors, adhesives, and heat.

  • Publication number: 20200405344
    Abstract: The present technology is directed generally to devices, systems, and methods for capturing and cutting fibrous and trabeculated structures (such as synechiae) in vessel lumens. In one embodiment, the present technology includes an intraluminal tissue modifying system configured to capture the fibrous structures, put the fibrous structures in tension, and controllably cut through the fibrous structures without applying appreciable additional force to the vessel wall. The system may include an expandable capture device and a cutting device.

  • Publication number: 20200289102
    Abstract: Devices, systems, and methods for treating damaged or diseased valves are disclosed. A representative embodiment includes an elongated shaft having a longitudinal axis, a proximal portion, and a distal portion, and a dissection arm at the distal portion. The dissection arm can have a longitudinal axis and be moveable between a low-profile state and a deployed state. In the deployed state, a portion of the arm can flex outwardly away from the longitudinal axis of the shaft. The arm is configured to be deployed within a space within a vessel wall such that, as the arm moves from the low-profile state to the deployed state, the arm pushes against vessel wall tissue at a periphery of the space, thereby separating tissue at the periphery to form a dissection pocket having a predetermined shape.

  • Publication number: 20190321064
    Abstract: A device and method for visualization of the intravascular creation of autologous valves, and particularly venous valve, is disclosed herein. One aspect of the present technology, for example, is directed toward a delivery catheter that can include a lumen configured to receive a dissection assembly and a trough having a plurality of transducers electrically coupled to a proximal portion of the delivery catheter. At least one of the transducers can be configured to emit a signal towards a portion of a blood vessel adjacent the trough, and at least one of the transducers can be configured to receive a reflection of the emitted signal.

  • Publication number: 20190320889
    Abstract: The present technology relates generally to devices and methods for intravascular evaluation of blood vessels. Many embodiments of the technology relate to the intravascular evaluation of blood vessels before, during and after creation of autologous valves. In one embodiment, for example, the present technology is directed to a method comprising intravascularly delivering a delivery catheter to a target location adjacent a vessel wall and engaging the vessel wall along a portion of the delivery catheter. The method can further include determining the location of a first circumferential periphery of a dissection pouch formed within the vessel wall, determining the location of a second circumferential periphery of the dissection pouch, and determining an angular width of the dissection pouch based on the location of the first circumferential periphery and the second circumferential periphery.

  • Publication number: 20190282259
    Abstract: A device and method for intravascular dissection of a body lumen, and particularly a blood vessel wall, is disclosed herein. One aspect of the present technology, for example, is directed toward a tubular elongated member having a lumen therethrough, wherein the elongated member includes a distal region configured to be positioned within a blood vessel wall. The distal region can include an angled distal face having a distal-most edge configured to puncture the vessel wall and a proximal-most edge. The member can include an exit port fluidly coupled to the lumen, and positioned along the distal face between the distal-most edge and the proximal-most edge. A central longitudinal axis of the exit port can be offset from a central longitudinal axis of the elongated member such that the exit port is closer to the distal-most edge than the proximal-most edge.
