| 摘要 |
The present invention is directed toward a modular prosthetic conduit implanted within a mammal, comprising a first conduit member (30) of a nonporous biocompatible alloplast having a distal end (30a), and a proximal end (30b). The invention further comprises a second conduit member (10) composed of a nonporous biocompatible alloplast having a distal end (10b), and a proximal end (10a) with a fixation region (11) located near one or both ends. The fixation region (11) includes an expansile/contractile means or component (14) within the wall. In a preferred embodiment, the expansile/contractile means or componen t (14) is a temperature sensitive material wherein radial expansion and fixation occur within the range of 35 .degree.Celsius to 38 .degree.Celsius. |
