GRAPAVASC - Banco de Patentes

The object of the invention is an instrument for surgical stapling between a vascular prosthesis and the aorta, comprising a handle, a stem associated with the handle, a head associated with the stem, a ring associated with the head, anterolateral staples, and posterior staples.

The development of automatic or semi-automatic end-to-end and end-to-lateral suture systems for tubular structures (intestine, biliary tract...) has numerous antecedents and designs in surgery over the last few decades. However, its introduction in the field of vascular sutures has been limited by various factors, such as being subjected to pulsatile blood flow at high pressure or the presence of wall irregularities (atheroma plaques) of varying consistency (fibrosis, lipids, calcium). It is for this reason, at least in part, that designs based on drums with circular suture lines (common in digestive surgery) have had limited application and little diffusion.
