With the demand for smaller procedures increasing, tubing manufacturers need to allow catheters to complete these tasks cost-effectively and efficiently.
FREMONT, CA: Catheters are increasingly becoming complex in terms of the tasks they can use, making the peelable heat-shrink tubing (PHST) market an exciting area to be involved in. It helps address healthcare customers’ demands and is paving the way for progressively smaller catheter-based procedures, which is an ongoing need for medical device manufacturers. Read on to know more.
The advantage of PHST is that it avoids peeling the outer fluorinated ethylene propylene (FEP) lamination layer, which can harm the catheter within. PHST also allows the final product to be produced more quickly with enhanced yields and fewer inspection levels while being increasingly ergonomically safe. Newer innovations are adding to PHST’s potentials. The PHST solution has been tailored to equip catheter manufacturers with the highest shrink ratio presently possible in pe
elable FEP. This solution lets them save time and money through a less number of shrink processes. PHST also allows the use of cost-effective, lower-tolerance, baseline materials in the manufacturing process and allows the potential to reflow seamlessly into a single smooth construct rapidly and efficiently. This results in a mitigated total cost of ownership for the catheter manufacturer.
There are extensive applications for this innovation, including neurovascular catheters with tapered diameters for the floppy distal segments and proximal sections with larger diameters for pushable support. Because these catheters are majorly being braid-reinforced proximally and coil reinforced distally, they require a PHST solution that can accommodate in a single step the compression needed to offer significant bond strength of the materials. Indeed, the trend toward procedures leveraging smaller catheters is driving the market toward miniaturization. This is scaling as medtech manufacturers demand catheter solutions that can penetrate harder-to-reach places.
Cut-to-length PHST is in demand because of its increased availability of custom-engineered diagnostic, interventional catheters developed for tougher procedures inside the body. Cut-to-length PHST is a perfect match for this as it can be cut to a specific size for a given need. The cut-to-length and slit option incorporates a peeling slit that enables faster throughput during manufacture, thus enhancing cost savings.
