摘要： Implant for supporting bodily conduits, such as blood vessels or/and grafted vessels, inside a subject. In exemplary embodiments, the implant includes a support fixedly displaceable and plastically stretchable to points along longitudinal axis of the support, when subjected to a stretching force, thereby forming a new shape, the support substantially maintains the new shape upon removal of the stretching force. The support, when forming the new shape, is plastically reversely compressible in a direction along the support longitudinal axis, when subjected to axially compressive force. Support may include a radially elastic portion configured to regain fixedly deformed diameter upon removal of radially compressive force applied thereto. Support is configurable as an intraluminal support for intraluminal deployment and setting in a conduit segment, or, as an external support for enveloping a conduit segment, so as to change route or/and shape of the conduit segment.
