Applications and Advancements for the Medical Device Industry
Resonetics has combined advances in laser and motion control to develop a cost-effective tool for high-volume manufacturing of catheter components. This innovative and highspeed laser cutting process is called PRIME™ Laser Cut.
The laser cut tubes (LCT) from the PRIME™ process have many advantages over traditional catheter manufacturing methods (such as braided or coil construction). Below are key benefits of PRIME™ LCT catheter components:
Customization: a key benefit of LCT over traditional catheter construction is the ability to completely customize the part geometry to match the clinical demands of the catheter. For example, if designing a catheter requiring significant stiffness on the proximal end but uniaxial flexibility on the distal end, this can be difficult to achieve with a traditional braiding or coiling technique.
Torque Transfer: LCT typically employs interrupted cutting which enables flexibility but maintains a monolithic connection from proximal to distal ends of the catheter. This direct connection ensures a good torque response when functioning the device in-vivo.
Kink Resistance: an additional advantage of the monolithic aspect is optimized kink resistance. As devices become more flexible, they inherently have a higher risk of kinking upon insertion and propagation through the anatomy. The PRIME™ process enables the design of flexibility and optimization of kink resistance without sacrificing functionality.
Ovality: a challenge with braided and coiled catheters is flattening or ovality as they move through difficult anatomy. Since LCT is monolithic it does not collapse as it propagates tortuous anatomy. This is critical when passing additional devices through the inner diameter of the catheter.
Low Profile: LCT based catheters can start with a relatively thin-wall tube (down to <0.0005”) while maintaining strength requirements of the catheter. Again, the monolithic benefits of LCT enable a reduced wall thickness of the catheter which opens up space for larger devices passing through the inner diameter.
