Medical device having laminate-coated braid assembly

摘要

A catheter includes a braid assembly having a dual-laminate coating. The braid assembly includes a plurality of braid members interwoven to provide for interstices between the braid members, each braid member having an electrically conductive element, a flexible non-electrically-conductive polymer coating that insulates the electrically conductive element and a thermoplastic bonding adhesive coating. The braid assembly is formed between an inner polymer layer and an outer polymer layer. One or more of the braid members may be coupled to an energy delivery element.

主权项

1. A catheter shaft, comprising:
an inner layer of a first polymeric material; an outer layer of a second polymeric material; a braid assembly formed between the inner layer and the outer layer, the braid assembly comprising a plurality of braid members interwoven to provide for interstices between the braid members, wherein each of the plurality of braid members comprises
an electrically conductive element having a first coating and a second coating, the first coating comprising a flexible non-electrically-conductive polymer that insulates the electrically conductive element, and the second coating comprising a thermoplastic bonding adhesive that bonds to the outer layer.
