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.
