ABSTRACT:
A shaft for a probe, especially suited for TEE and nasogastric applications, with superior bite-through resistance in the outermost probe layer. The probe shaft includes a crush-proof monocoil surrounded by coiled sheathing and an outermost layer of heat shrinkable polymer tubing. The heatshrinkable polymer provides superior resistance to lacerations from sharp objects such as patients teeth. Moreover, in an embodiment using clear polymer over darker inner layers marked with light colored depth markings, the depth markings are protected from wearing off. The preparation method includes inserting a monocoil and sheath into a tube of heatshrinkable material and applying heat sufficient to cause the heatshrinkable material to mechanically adhere to the sheath.
