CAROTID SHEATH WITH ENTRY AND TRACKING RAPID EXCHANGE DILATORS 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.

主权项

1. A dilator for use in connection with a sheath, the dilator comprising:
an elongate main body extending from a proximal end of the dilator to a distal end of the dilator, the elongate main body comprising:
a proximal portion extending longitudinally from the proximal end of the dilator; anda distal portion directly adjacent to and extending longitudinally from a distal end of the proximal portion of the elongate main body to the distal end the dilator; a lumen disposed within and extending longitudinally along an entire length of the elongate main body; a distal opening in fluid communication with the lumen, the distal opening disposed at the distal end of the elongate main body; and a slot extending from the lumen through a sidewall of the elongate main body, the slot extending longitudinally from the proximal end of the dilator to a proximal end of the distal portion; wherein the distal portion comprises a continuous circumference.
