摘要： A low profile catheter valve comprising a movable sealer portion (30) is positioned within the inflation lumen (40) of a catheter. The sealer portion (30) forms a fluid tight seal with the inflation lumen (40) by firmly contacting the entire circumference of a section of the inflation lumen (40). The sealer portion (30) may be positioned proximally of a side-access inflation port (22) on the catheter, to extablish an unrestricted fluid pathway between the inflation port (22) and an inflatable balloon (20) on the distal end of the catheter. As desired, the clinician may move the sealer portion (30) to a position distal of the inflation port (22), thereby preventing any fluid from being introduced into or withdrawn from the balloon (2) via the inflation port (22). An inflation adaptor (200) moves the sealer portion (30) within the catheter to establish or close the fluid pathway between the inflation port (22) and the inflatable balloon (20). In use, the catheter is placed into the adaptor (200) with the sealer portion (30) to a second position which allows passage of fluid into the inflation lumen (40). An actuator (220) on the adaptor (200) is used to drive the sealer portion (30) to a second position which allows passage of fluid into the inflation lumen (40). The balloon (20) is then inflated and the actuator (220) is used to move the sealer portion (30) to again block the inflation lumen (40). The adaptor (200) is configured to allow the sealer portion (30) to be driven to a third position which is further from the inflation port (22) than the first position.
