Carotid sheath with rapid exchange dilator for access and tracking and method of use

摘要

Dilators and sheaths for use in minimally invasive vascular therapy are disclosed. In some embodiments, the dilators include a slot that accesses a guidewire lumen within the dilator. These slots facilitate rapid exchange of one dilator for another. In another embodiment, a dilator is sufficiently stiff to facilitate entry, but also designed to facilitate placement of the dilator along a tortuous path.
