NOTE: Viking connectors are round with 4 pins

NOTE: The MPR-500 is a thromboresistant, low-cost reusable catheter designed for intraoperative placement. It can be used for post open-heart pressure monitoring. The MPR-500 provides accurate high fidelity pressure monitoring with no damping or danger of air embolism. The MPR-500 is non-repairable and warranted for 30 days against defects in materials and workmanship.

Single Pressure Sensor With Lumen

Slow-Speed Injection and Sampling
Approved for Human Use. Millar manufactures and markets a line of Mikro-Tip pressure catheters with a lumen for fluid sampling or slow-speed injection; all are available in sizes from 5 to 7 French.

High-Speed Injection
Millar manufactures and markets two models of single sensor catheters for high-speed injection. The lumen has two laterally opposed side openings on the SPR-471A. The SPR-474A has an open-end pigtail extension for use with a .032 inch (.8 mm) guide wire. Typical injections rates of radiopaque contrast dye (Renografin 76) at 1200 psi (8274 kPa) are 10 to 15 ml/sec. The SPR-471A injection lumen side openings are located 1 cm from the tip, and the model SPR-474A injection lumen is located 1 cm from the pigtail attachment.

Dual Pressure Sensor

Millar manufactures and markets a line of dual pressure sensor catheters for simultaneous high fidelity pressure measurements. These catheters are suitable for measuring pressure gradients across a valve, between chambers, or across a vascular stenosis. The catheters are made of polyurethane material (some include a woven dacron braid), are thromboresistant, and range in size from 2.5 to 7 French.
