SHEATHLESS GUIDE, RAPID EXCHANGE DILATOR AND ASSOCIATED METHODS

摘要

Dilators, such as rapid exchange dilators, configured for percutaneous access are disclosed. The dilator may be configured to be disposable within, or couplable with, a catheter. In some embodiments, the dilator, or the coupled dilator and the catheter, may be configured such that a sheath is not required for percutaneous access. In other embodiments, the dilator may comprise a plug such that a guide wire may be directed from a distal end of the dilator through a port, such as a rapid exchange port, in a sidewall of the dilator. The plug may also be configured to permit passage of fluid through a lumen of the dilator while inhibiting passage of the guide wire through a length of the dilator.

主权项

1. A dilator configured for percutaneous access, the dilator comprising:
an elongate member comprising a proximal end and a distal end; a lumen disposed within at least a portion of the elongate member; and a port disposed in a sidewall of the elongate member, wherein the port is in fluid communication with the lumen.
