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.

Embodiment Construction

[0064]The embodiments discussed herein include devices, systems, and methods useful for providing selective autoretroperfusion to the venous system. In addition, and with various embodiments of devices and systems of the present disclosure, said devices and / or systems can also be used to achieve a controlled arterialization of the venous system. For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of this disclosure is thereby intended.

[0065]The devices, systems and methods disclosed herein can be used to safely and selectively arterialize venous vessels in order to decrease the stress thereon and prevent rupture of the same. Accordingly, through the use of the devices, systems and methods disclosed herein, long-term autoretroperfusion of oxygenated...
