Abstract
Alternative design, material, manufacturing method, and use for medical devices, such as catheters, catheter shafts and the like. An example includes a medical device, such as a catheter shaft, including an elongated tubular braid comprising a plurality of filaments and including an end portion coated with a first polymeric material having a first melting point temperature, wherein the first polymeric material attaches the braid filaments together. A second polymeric material having a second melting temperature lower than the first melting point temperature may be attached to the coated end portion of the braid. In some embodiments, the underlying a first polymeric material may reduce the tendency of the braid to flair into the second polymeric material. Other examples relate to methods of making such medical devices, such as a catheter shaft, of the like.
