  • Patent number: 5421825
    Abstract: The vascular introduction device is of the lateral arm type. It comprises a tubular body defining an introduction channel enabling, after installation of the distal part of the introduction device in a blood vessel of a patient to be treated, the introduction of a catheter into the vascular system up to where the operation is be performed. The introduction device is provided over part of its length with a longitudinal bulge whose inner wall defines a cavity merged with the introduction channel and communicating directly with the lateral arm. The tubular body is provided with blood inlet orifices arranged at least in the wall defining the cavity. The lateral arm thus enables feeding of a closed external blood circuit comprising a perfusion pump, with a sufficient blood rate in terms of pressure and flow, equal to the rate that would be obtained by a contralateral puncture point. The blood thus sampled off can be reinjected into the patient via the dilatation catheter.

  • Patent number: 5057120
    Abstract: An apparatus for the performance of an angioplasty of long duration comprises a catheter associated with a flexible guide rod and provided with a dilation bulb which is intended to be inflated at the required location. The opposite end of the catheter is connected to a perfusion pump, the operation of which is dependent on a control unit for synchronizing its operation with the electrocardiogram of the patient to be treated in order to carry out downstream of the dilation bulb a perfusion of blood or of oxygen-transporting physiological liquid at a variable flow rate corresponding to the physiological diastole and systole phases of the patient's heartbeat. To this end, the guide rod is mounted on the catheter or on the dilation bulb in order to avoid any interference with the circulation of liquid through the catheter and at the outlet of this latter, thus permitting perfusion of blood or of physiological liquid downstream of the dilation bulb throughout the period of inflation of the bulb.

  • Patent number: 4459977
    Abstract: An apparatus for diastolic blood retroperfusion of the coronary sinus in synchronism with the heartbeat rate for the treatment of infarctions. A connecting tube between an artery and the coronary sinus is fitted with a balloon-type catheter. A pulsatile unit mounted on the tube is controlled by an electrovalve in dependence on an electronic console and in synchronism with the patient's electrocardiogram (ECG) in order to retroperfuse arterial blood in the coronary sinus during diastoles and to permit the return flow of vitiated blood to the lungs during systoles. The apparatus permits diastolic retroperfusion of arterial blood in synchronism with the patient's electrocardiogram with maximum safety.
