Apparatus for treatment of aorta disease with a balloon expandable section

An endoprosthesis apparatus for treating aortic artery disease, comprising:

• a delivery catheter;
• a stent graft navigable through the catheter, the stent graft including:
• a proximal balloon-expandable metallic segment configured for precise positioning via balloon inflation;
• a distal self-expandable segment configured to automatically expand upon deployment;
• a set of radial or longitudinal sutures joining the balloon-expandable segment to the self-expandable segment;
• and
• a plurality of radiopaque markers affixed to the balloon-expandable segment and visible under fluoroscopy to facilitate precise placement, wherein the balloon-expandable segment is deployed prior to the self-expandable segment.

A hybrid stent graft apparatus for endovascular treatment of aneurysms, dissections, or injuries in the aorta, comprising:

• a proximal balloon-expandable section configured to be positioned at a target region and anchored through balloon expansion;
• a distal self-expandable section configured to conform to the patient's anatomy and maintain fixation through radial force;
• a plurality of radially distributed and equidistant radiopaque markers affixed to the balloon-expandable section;
• and
• a radial or longitudinal suturing interface joining the balloon-expandable and self-expandable sections enabling structural continuity and synchronized deployment, wherein the apparatus is adapted for sequential deployment such that the balloon-expandable section is deployed and anchored before release of the self-expandable section.
