Catheter, angiography

Angiography catheters facilitate access via the

Seldinger technique to arterial and venous structures to perform selective catheter-based diagnostic angiography by injection of contrast. These devices are indicated for delivery of contrast medium in angiographic studies and for simultaneous pressure measurement, which is useful in determining trans-valvular, intravascular and intra-ventricular pressure gradients in the cardiac and pulmonary systems.
