LANGSTON Dual Lumen Catheter - Catheter, angiography

Intended purpose

The LANGSTON dual lumen catheter is intended for use as an angiographic pressure measurement catheter and for high pressure contrast injections. Each LANGSTON dual lumen catheter is indicated for delivery of contrast medium in angiographic studies and for simultaneous pressure measurement from two sites. This type of pressure measurement is useful in determining trans-valvular, intravascular and intra-ventricular pressure gradients.

Functional description

Consists of inner, braided high pressure lumen, used for pressure measurement & rapid delivery of contrast medium, & an outer lumen that ends 3-15cm proximal to the distal end with side-holes for pressure measurement only. The inner & outer lumens are joined using an adapter junction at the proximal end. The adapter junction has a side port fitted with an extension tubing & stopcock assembly for fluid flow & pressure measurement in the outer lumen. A straightener is supplied with pigtail models.
