Abstract
A catheter system may comprise an elongated access assist device configured to receive a guidewire during a thrombectomy. The device may include a hemostasis valve coupled to a proximal end of the device, whereby the valve controls fluid flow between a proximal portion and a distal portion of the device. The device may also include a flush port coupled to the proximal portion, where the flush port is configured to couple to a fluid supply source and facilitate the release of fluid from the fluid supply source through the elongated access assist device. The fluid may be configured to be released through a plurality of microperforations located along the body of the device, as well as on a distal tapered portion of the device. The distal tapered portion, combined with the release of fluid through the microperforations, may ease navigation of the system through the vasculature.
