  • Patent number: 10610669
    Abstract: A biologics delivery device and method of use for promoting angiogenesis in occluded vessels and ischemic tissue of a patient are provided, wherein the biologics delivery device includes a catheter having a proximal end, a distal region having a distal end, a lumen extending there between, and a plurality of through-wall apertures distributed along the distal region, the plurality of through-wall apertures in fluid communication with the proximal end and the lumen, and an expandable member disposed in the distal region, the expandable member configured to transition between a collapsed state and an expanded state. Methods of using the inventive biologics delivery device also are provided to achieve substantially uniform distribution of the biologic into a subintimal space.

  • Publication number: 20180078243
    Abstract: Bone marrow harvesting devices and methods of use for harvesting bone marrow from a biological source of bone marrow are provided that promote ease of use, and reduce patient pain and potential trauma to harvested bone marrow, wherein an exemplary bone marrow harvesting device includes an elongated shaft comprising a distal region, a proximal region, and a lumen extending therebetween, the distal region comprising a plurality of through-wall apertures in fluid communication with the lumen; and an expandable member disposed along the distal region thereof and configured to transition between a collapsed state and an expanded state for vibrating to disrupt the bone marrow. Methods of using the inventive bone marrow harvesting device to provide more efficient bone marrow disruption, improve the efficiency of bone marrow aspiration, and increase the quantity of bone marrow harvested in a single procedure are also provided.

  • Publication number: 20170266411
    Abstract: A biologics delivery device and method of use for promoting angiogenesis in occluded vessels and ischemic tissue of a patient are provided, wherein the biologics delivery device includes a catheter having a proximal end, a distal region having a distal end, and a side wall defining a catheter lumen; an expandable member disposed in the distal region, the expandable member configured to support a subintimal space in an occluded blood vessel of a patient, and to transition between a collapsed state and an expanded state; and a hollow needle having a penetration tip deployable from inside the catheter lumen to outside the catheter lumen, and into tissue surrounding the occluded blood vessel, wherein the expandable member in the expanded state allows the flow of oxygenated blood to the occluded blood vessel. Methods of using the inventive biologics delivery device also are provided to deposit the biologic from a subintimal space to tissue surrounding the occluded blood vessel.

  • Publication number: 20140378890
    Abstract: A catheter and methods for luminal therapy are provided wherein a catheter has an outer balloon with a multiplicity of apertures for infusing one or more therapeutic agents into a vessel wall, an intermediate balloon having a multiplicity of apertures offset from the apertures of outer balloon to serve as a baffle that reduces jetting and promotes uniform distribution of therapeutic agent exiting through the outer balloon, and an impermeable inner balloon disposed within the intermediate balloon that enables the intermediate and outer balloons to be forced into engagement with the vessel wall to dilate the vessel and disrupt plaque lining the vessel wall and to also facilitate the uniform delivery of the therapeutic agent.
