| A replacement biopsy channel is made of two kinds of PTFE. |
International Polymer Engineering (Tempe, AZ; www.ipeweb.com) has filed for a second patent describing a replacement biopsy channel for the repair and OEM endoscope manufacturing industry.
The inner layer of the channel is made of solid PFTE. Its inherent lubricity allows instruments to pass freely with minimal drag.
The outer layer is porous PTFE with a
spiral wound support incorporated into
the structure for radial support of the inner layer. This layer acts like a spring wrap
and provides kink and compression
resistance.
Both layers of materials have a long history of use in medical products and have a Class VI implant rating. The company has also designed and developed suction channels and light-guide covers for OEMs.
