摘要： An inflation device includes a syringe forming a cylindrical chamber containing a plunger carrying a stopper or piston arrangement. The chamber is designed to contain an inflation fluid and is in fluid communication with the lumen of a balloon catheter. Movement of the plunger within the chamber will increase or decrease the pressure of the fluid within the chamber and lumen, thereby inflating or deflating the balloon at the distal end of the catheter. A pressure sensor is mounted to the housing in fluid communication with the lumen and is electrically connected to a battery-operated transmitter. The transmitter broadcasts signals representing pressure within the lumen and balloon to a remote receiver. The receiver includes a microprocessor containing a clock and operable to display time and pressure data. A flexible insulator strip is interposed between the battery and the transmitter circuit to prevent operation of the transmitter until desired by the cardiologist. The housing of the inflation device may be opened to remove the batteries for separate disposal and to render the circuit inoperative to prevent reuse. A look-up table associated with the microprocessor permits display of balloon diameter during the procedure.

摘要： Inflation apparatus for inflating a dilatation balloon of a catheter includes a frame having a first receiver supporting the barrel of a syringe. An operator has a second receiver supporting the plunger of the syringe. The syringe includes a fluid port for connecting the syringe chamber to the lumen of the catheter. A motor is supported by the frame and operatively connected to the operator to move the piston to change fluid pressure within the syringe chamber. A release device permits quick release of the pressure in the balloon catheter without the use of the motor. A pressure sensor is mounted to the frame to measure the pressure in the chamber through a diaphragm on the syringe. The pressure sensor operates a microprocessor-controlled display, which provides display of inflation and duration information and calculates other information. A circuit selectively operates the motor. An inflation control connected to the circuit permits operation of the motor at selected rates of inflation/deflation or to selected specific inflation pressures.
