Abstract: In some examples, a catheter includes one or more balloons positioned between an inner wall and an outer wall of an elongated body of the catheter. The one or more balloons are configured to expand through one or more inner wall openings defined by the inner wall and into an inner lumen of the catheter, as well as through one or more outer wall openings defined by the outer wall, e.g., to extend radially away from an outer surface of the outer wall of the catheter. In some examples, the one or more balloons are configured to expand radially inward through the one or more inner wall openings and into the inner lumen of the catheter to contact (e.g., directly contact) a guidewire positioned within the inner lumen.

Abstract: A vasculature access device may include a needle, a dilator, an introducer sheath, a hub, and manipulators in a single, integrated device. The vasculature access device may also optionally include one or both of a guidewire and one or more features for facilitating restraint of the hub and the introducer sheath relative to a patient. By integrating the needle, dilator, introducer sheath, hub, and manipulators in a single device, exchanges of these components (e.g., removing one component from the vasculature and introducing a different component into the vasculature), which is done in access kits where at least some of these components are separate, are reduced.
