Large inner diameter vascular sheaths are key consumables commonly used in interventional surgeries and are widely applied in the interventional treatment of fields such as structural heart diseases and large stent delivery systems. With the continuous development of medical technologies, especially the increasing number of high-precision and highly complex interventional surgeries, the application of large inner diameter vascular sheaths has become particularly important.
One of the main design objectives of large inner diameter vascular sheaths is to provide sufficient space for interventional devices. In the lumen channel of the vascular sheath, the thinner the wall thickness, the larger the inner lumen diameter that can be provided. Especially in complex interventional surgeries, increasing the lumen space is a prerequisite for ensuring the smooth progress of the operation.
When designing large inner diameter vascular sheaths, there are usually challenges in terms of strength and durability. In a high-pressure environment, the device itself is required to have strong enough mechanical properties to reduce the risk of vascular injury and complications.
When designing large inner diameter vascular sheaths, it is necessary to ensure smooth operation with low resistance, so as to facilitate the insertion and operation of other devices.
Based on the above points, for large inner diameter sheath tubes that require smooth instrument introduction and reduce the risk of injury, the use of high-performance PTFE Liner with ultra-thin walls and large inner cavities is a very ideal design choice.
High tolerance requires that PTFE inner lining tubes have higher strength to ensure the stability and safety of the equipment during use. If the wall thickness is too thin, its mechanical strength will be reduced. Especially when subjected to higher pressure or greater mechanical stress, thin-walled inner lining pipes are more prone to deformation or even rupture.
jMedtech provides three mainstream production processes for PTFE Liners: Free Extrusion, Over-The-Wire Extrusion (OTW), and Film Cast. It also adopts surface etching technology, which offers excellent bonding performance. The engineers at jMedtech will provide appropriate process options according to different application scenarios and catheter type designs to match the size, strength, and flexibility combinations required by customers.
The PTFE Liners of jMedtech are made of high-purity polytetrafluoroethylene raw materials, which have excellent lubricating properties. They can significantly reduce the resistance when devices pass through the sheath, making it easier for catheters, guidewires, or other interventional devices to pass through the sheath smoothly and avoid jamming.
By providing a full set of high-quality PTFE Liner solutions, jMedtech has become an ideal partner for many customers of large inner diameter vascular sheaths.
In addition, jMedtech strictly follows the ISO13485 system to build a standardized Class 10,000 clean workshop. The entire process, from raw material feeding to packaging, is carried out in the clean workshop, which fully meets the biological requirements of medical devices. At the same time, it can quickly respond to market changes and provide products with a short delivery cycle (the fastest delivery time for standard products is 7 working days, and the delivery time for commonly customized sizes is 4-8 weeks).
