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. This vascular introduction device is mainly destined for use in a radiological or heart surgery operation.
