Catheter with detached proximal inflation and guidewire shafts

摘要

A catheter (100) comprises an inflation shaft (104) having proximal portion (104A), a distal portion (104B) and an inflation lumen; a guide wire shaft (106) having a proximal portion (106A), a distal portion (106B) and a guide wire lumen; and a conversion joint located distal of the proximal portions of the guide wire and inflation shafts. The proximal portion of the guide wire shaft and inflation shaft are detached and separate.

The proximal portion of the guide wire shaft and inflation shaft are detached and separate. The proximal portions of the inflation and guide wire shafts transition are coaxial in the distal portion of the catheter. The catheter further comprises guide member containing proximal guide wire exit.
