Dilation cap for endoluminal device

摘要

A dilation cap (200) may include a distal tip (210), an intermediate body (220), and a proximal coupling member (230). The distal tip may at least partially surround a longitudinal axis (205) of the dilation cap and may include a cavity to receive a distal end (122) of a cannula (120) of a medical device (100). The intermediate body may extend proximally from the distal tip and include a dilator portion. The dilator portion may include a projection (228) extending laterally in a direction away from the longitudinal axis of the dilation cap. The proximal coupling member may extend proximally from the intermediate body and at least partially surround the longitudinal axis of the dilation cap. The proximal coupling member may be configured to engage an intermediate portion of the cannula of the medical device. The intermediate body may be asymmetrical with respect to the longitudinal axis of the dilation cap.
