摘要

Conventional stent graft device Kit + stent graft pulsu00c1til help the activity circulatu00d3ria applied in patients with insuficiu00cancia frame rate.Represented by an inventive solution in the area of medicine, particularly useful when the auxiliary circulatory activity where the patient presents the framework of heart failure, and this was created a endoprotese pulsatile device (2), activated by any luck fo Only energy.This structural device whose tubular body (2a) is made primarily in the material with effect of "shape memory".It ensures the said device to create a mechanical cycle formed by alternation of the state relaxed and activated state of the device stent (2) that converges in the pulsatile blood circulatory assistance where in the state relaxed its structural tubular body (2a) is flexible.With low radial strength and fully deformable by blood pressure and in activated state where the tubular body structure (2a) has its amended form, compressed radially and reducing the diameter of the endoprosthesis (2), pulsatile blood flow in a guaranteed effective region of the conduit (A1) into which is introduced a endoprotese conventional (1).
