Abstract
An inflator for use with a catheter having an inflatable component wherein the inflator includes a housing having an elongated plunger passage and an elongated gage passage. The housing includes a one piece main body which defines at least major lengths of both of the passages, and the passages extend in generally side- by-side relationship. The housing has a port which communicates with both of the passages and which can be coupled to the inflatable component of the catheter. A plunger is movable longitudinally in the plunger passage and is extendible out of a plunger opening in the plunger passage. A pressure responsive gage member is movable longitudinally in the gage passage and is responsive to pressure of the fluid adjacent the port. An indicator is responsive to the longitudinal position of the gage member to provide an indication of the pressure of the liquid adjacent the port. A releasable lock carried by the housing limits the plunger movement. The lock is retained in a locked position responsive to pressure in the plunger passage.
