    摘要: The present invention is a device and method for controlling longitudinal movement of a tube relative to a shaft slidably disposed within the tube, especially in the catheterization of a patient. An operative segment on the shaft cooperates with an ancillary tool to create a coupling force field between the shaft and the tool. The tube can then be moved over the shaft while the coupling force field operates through the tube to restrict the movement of the shaft. In preferred embodiment, the shaft is a guide wire and the tube is a catheter with a lumen for slidably receiving the guide wire, while the coupling force field is created magnetically. In one embodiment, the operative segment is borne on a short guide wire extension which is selectively securable to a standard guide wire. In another embodiment, the tool has a telescoping handle for adjusting the handle length, and a movable cover for retaining the guide wire.

    摘要: A balloon catheter which has an elongate shaft with an inflatable balloon connected to its distal end and a manifold connected to its proximal end. The manifold may be fixedly or removably attached to the shaft and includes a barrel with a plunger movably disposed inside it. The manifold may be held with one hand and the plunger may be actuated with one finger or thumb on the same hand. The barrel may have an internal volume of less than 5 cc and an internal diameter of less than 0.25 inches. The catheter also has a prep port which may be connected at or near the proximal end of the catheter. The prep port facilitates prepping of the catheter system. A seal (e.g. a releasable cap or a valve) may be connected to the prep port for sealing off the prep port during use. A pressure transducer may be mounted to the catheter (e.g. on the shaft, the manifold, the prep port, or the seal) to permit measurement of the pressure within the inflation lumen and the balloon. The pressure transducer may be operably connected to a pressure display and the display may be connected to the proximal end of the catheter or may be remotely located from the catheter. Data may be transmitted to the remote display by wire or wireless transmission (e.g. infrared, radio frequency, or magnetic transmission). Alternate embodiments and methods of use are also disclosed.

    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.
