AI Technical Summary

Benefits of technology

The present patent is about a perfusion device that can be used to treat or prevent damage to the heart. The device has a flexible body that can be positioned within the heart and can deform easily without collapsing. The device has a first portion that can be positioned within a subclavian artery or axillary artery, and a second portion that can be positioned within a subclavian vein or axillary vein. The second portion has a first tapered portion that helps to reduce the risk of rupture of the vein and also helps to decrease blood pressure during use. The device can be designed to regulate the pressure drop along its length to avoid over-pressurization of the vein system. The device can be easily implanted within the vein and can bend at various angles to accommodate the anatomy of the heart and veins. The technical effects of this patent are a flexible and easily implantable perfusion device that can help to treat or prevent damage to the heart while reducing the risk of rupture of the vein system and decreasing blood pressure during use.

Problems solved by technology

Peripheral arterial disease involves inadequate blood supply to the peripheral limbs due to arterial damage, defect, or blockage.
