Advanced Solutions for Cardiovascular Catheter Design
Cardiologists see potential in smaller-diameter catheters for less invasive procedures and easier navigation of complex vascular pathways. At the same time, they look for precise, high-resolution imaging for safer and more effective insertions and investigations. And like all critical medical devices, cardiovascular catheters need to perform consistently, without failure.
To improve upon cardiac catheter design, engineers require compact connectors that minimize the size and weight of the device without sacrificing performance; high-efficiency optical fibers and waveguides to transmit light with minimal loss and heat generation; and in-parallel, low-power electronics with advanced power management integrated circuits (ICs) to conserve battery life.
Molex delivers high-density interconnect solutions, advanced optical fibers and low-power electronic designs that make these improvements possible. The precise impedance matching and high-quality materials in Molex connectivity solutions help to realize new levels of signal integrity, advancing miniaturization, imaging resolution and the overall reliability of cardiac catheter systems.

Cable Assemblies for Cardiovascular Catheters
When designing cardiovascular catheters, engineers look to maintain signal integrity by reducing both internal and external interference and minimizing signal loss. Molex cable assemblies are designed with advanced shielding to guard against EMI and RFI, ensuring consistent and clear signal transmission. Additionally, high-quality materials and precision manufacturing in connectivity solutions prevent signal degradation, promoting reliable and accurate data transfer along the entire length of cable.
Sensors for Cardiac Catheter Design
Accurate sensor output is a critical objective in cardiovascular catheter development, where engineers must address temperature variations and define precision levels. Molex's pre-calibrated negative temperature coefficient (NTC) sensors eliminate the need for calibration, delivering reliable temperature measurements with higher performance than standard alternatives due to their precise manufacturing tolerances.
Operating Temperature | Beta Range | Resistance Range | |
