Patent number: 6997908Abstract: A single operator exchange biliary catheter having a common distal lumen. The biliary catheter includes an elongate shaft having a proximal portion defining 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 the 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.Type: GrantFiled: December 20, 2002Date of Patent: February 14, 2006Assignee: SciMed Life Systems, Inc.Inventors: Oscar R. Carrillo, Jr., James Yearick, Robert C. Allman, Fernando Alvarez de Toledo, Michael Ciannella, Stephen C. Evans

Patent number: 6562024Abstract: A single operator drainage catheter delivery system and method of use. The delivery system includes a guide member having a guidewire lumen extending through a distal portion thereof, with a proximal guidewire port located distal of the proximal end. A placement catheter disposed over the guide member has a catheter lumen extending through a distal portion thereof, with a proximal guidewire port located distal of the proximal end. Locating the proximal guidewire ports as such allows the delivery system to be used by a single person with a shorter guidewire. A drainage catheter is disposed about the guide member distal of the placement catheter. The drainage catheter delivery system preferably includes a means for releasably connecting the placement catheter to the drainage catheter, wherein the releasable connecting means disconnects the drainage catheter upon displacement of the guide member.Type: GrantFiled: May 11, 2001Date of Patent: May 13, 2003Assignee: SciMed Life Systems, Inc.Inventors: Fernando Alvarez de Toledo, Michael Ciannella, Susan M. Ostrowski, Albert N. Solbjor
