Conduit designs and related methods for optimal flow control
First Claim
1. A bypass conduit for implantation in a heart to bypass an at least partially occluded artery, comprising:
- a first end defining a first opening;
a second end opposite the first end and defining a second opening; and
a wall extending between the first and second ends defining a lumen extending between the first and second openings, wherein said ends and said wall are configured such that the conduit has a greater resistance to blood flow in a first direction than in a second direction.

Abstract
A bypass conduit and related methods include implanting a bypass in the heart between a heart chamber and an at least partially occluded artery to directly flow blood from the chamber to the artery. The bypass conduit is configured to have a higher resistance to blood flow in a first direction than in a second direction without any active flow control mechanism. The bypass conduit may have a first end defining a first opening and a second end defining a second opening and a wall extending between the two ends that defines a lumen extending between the two openings. The ends and the wall of the conduit are configured to have a higher resistance to blood flow in a first direction than in a second direction. A method of bypassing an at least partially occluded artery includes determining a resistance to blood flow of the artery at a location of an at least partial occlusion and selecting a conduit having a configuration based on the resistance to blood flow of the artery at the location of the at least partial occlusion. The method further includes implanting the conduit in a heart wall between the heart chamber and the artery downstream of the at least partial occlusion to directly flow blood between the chamber and the artery.
