SINGLE OPERATOR EXCHANGE BILIARY CATHETER WITH COMMON DISTALLUMEN

摘要

A single operator exchange biliary catheter having a common distal lumen. Th e biliary catheter includes an elongate shaft having a proximal portion defini ng an ancillary lumen and a distal portion defining a common guidewire and ancillary lumen. The common distal lumen reduces the profile of the distal portion of the shaft. The elongate shaft also includes a proximal guidewire port disposed between the proximal end of the shaft and the distal end of th e shaft to facilitate single operator use. A seal may be disposed adjacent the proximal guidewire port to thereby seal the port. preferably, the shaft includes a single lumen distal portion and a bi-lumen proximal portion. The single lumen distal portion of the shaft may be curved and may include a tapered or spherically shaped distal tip.
