This invention relates to an implant, implant tools, and an implant technique for the interposition of an extracardiac conduit between the left ventricle of a beating heart and the aorta to form an alternative one-way blood pathway thereby bypassing the native diseased aortic valve. The implant consists of a hollow conduit having a first end opening, a second end opening, and a one-way valve located between the end openings. The valve is biased to allow one-way flow from the second end opening to the first end opening. A first slit opening is located between the first end opening and the valve and a second slit opening is located between the second end opening and the heart valve. The implant tools consist of a vessel wall cutting tool and a heart wall piercing and dilating tool. The vessel wall cutting tool is sized to closely fit through the implant's first slit opening and the first end opening. The heart wall piercing and dilating tool is sized to closely fit through the implant's second slit opening and the second end opening. The implant technique allows the surgeon to safely connect the implant between a heart chamber and a blood vessel without stopping the heart or impeding flow in the blood vessel.

The halo implant technique described herein employs a halo implant mask that creates a halo implant shadowing effect during halo dopant bombardment. A first transistor device structure and a second transistor device structure are formed on a wafer such that they are orthogonally oriented to each other. A common halo implant mask is created with features that prevent halo implantation of the diffusion region of the second transistor device structure during halo implantation of the diffusion region of the first transistor device structure, and with features that prevent halo implantation of the diffusion region of the first transistor device structure during halo implantation of the diffusion region of the second transistor device structure. The orthogonal orientation of the transistor device structures and the pattern of the halo implant mask obviates the need to create multiple implant masks to achieve different threshold voltages for the transistor device structures.
