US 2026/0272436 A1 · IMPLANT FOR VASCULAR CLOSURE

Abstract

An implantable device for sealing an aperture in a tissue of a body vessel includes: an external fixation disposed on the outside of a vessel wall; a scaffold disposed on the inside of the vessel wall and interfacing with the external fixation, at least a portion of the scaffold disposed through an aperture in the vessel wall; and a patch disposed on the inside of the vessel wall and sandwiched between the external fixation and the scaffold, the patch substantially covering the full area of the aperture, thereby sealing the aperture. A delivery and system for delivering an implantable device includes: a delivery device to deliver the implantable device to the aperture location and to seal the implantable device over the aperture; a sheath and dilator assembly; and a packaging assembly. In some embodiments, the external fixation may include one or more hinge points.
