Abstract
Abstract A cardiac support device comprising a jacket of flexible and biocompatible material having a first axis for alignment generally parallel to a longitudinal axis of a patient's heart and a second axis that is transverse to the first axis. The material exhibits an amount of expansion in response to a force applied to the material along the first axis that is different than an amount of expansion in response to the force applied to the material along the second axis.
