摘要： An example medical apparatus includes a tubular structure. The tubular structure includes an echogenic layer that is a multiphase polymer composite. The multiphase polymer composite includes a polymer matrix phase, a first non-polymeric phase including gas voids entrapped within the polymer matrix phase, and a second non-polymeric phase including particles embedded within the polymer matrix phase. Catheters having respective echogenic layers are also described.

摘要： A method of manufacturing a tube assembly includes surrounding an outer surface of a cured rubber hose with a thermoplastic layer, the cured rubber hose extending along a length between a first end and a second end and having a first shape along its length, the thermoplastic layer surrounding the cured rubber hose along at least a portion of the length. The cured rubber hose surrounded with the thermoplastic layer is molded into a second shape different than the first shape. The cured rubber hose is retained in the second shape by the thermoplastic layer. A tube assembly includes a cured rubber hose and thermoplastic layer surrounding the rubber hose along at least a portion of the length of the cured rubber hose. The cured rubber hose has been cured in a first shape along its length and the thermoplastic layer retains the cured rubber hose in a second shape.
