Implantable flow connector
First Claim
1. An implantable flow connector implantable into a body of a patient for fluidly coupling a first space within the body with a second space within the body, the implantable flow connector comprising:
- a conduit having a lumen having a first orifice at a first portion of the conduit and a second orifice at a second portion of the conduit, the conduit configured to be implanted into the second space within the body to provide communication between the first and second spaces within the body; and
a flange radially extending from the first portion of the conduit, the conduit extending at a first angled direction with respect to the flange so a longitudinal axis of the conduit is at an acute angle to a longitudinal axis of the flange, the flange configured to be implanted in the first space within the body, the flange having first longitudinal section extending from a first side of the conduit, a second longitudinal section extending from a second side of the conduit opposing the first side, a first lateral section extending from a third side of the conduit and a second lateral section extending from a fourth side of the conduit opposing the third side, the adjacent lateral and longitudinal sections being contiguous, the first longitudinal section having a heel portion of a first configuration and the second longitudinal section having a toe portion of a second configuration different from the first configuration, the heel portion forming an acute angle with the longitudinal axis of the conduit and the toe portion forming an obtuse angle with the longitudinal axis of the conduit, and a length of the first longitudinal section defined from adjacent the conduit to a terminal end of the heel portion is greater than a length of the second longitudinal section defined from adjacent the conduit to a terminal end of the toe portion.

Abstract
An implantable flow connector for fluidically coupling a source tissue-enclosed body space with a destination element, comprising: a conduit having a lumen terminating at an orifice at a first end of the conduit implantable in the source body space through an opening formed in a tissue wall of the source body space, and a second end of the conduit implantable in the destination element through an opening in a surface of the destination element; and a circumferential flange, radially extending from the conduit proximate the conduit first end, configured to be implanted in the source body space adjacent an opening in the tissue wall of the source body space such that the conduit extends through the opening, the flange comprising one or more circumferentially adjacent sections at least one of which has a rigidity that decreases in a radially-increasing direction.

12. An implantable flow connector for fluidly coupling a first space within the body with a second space within the body, the implantable flow connector comprising:
-
a conduit having a lumen having a first orifice at a first portion of the conduit and a second orifice at a second portion of the conduit, the conduit configured to be implanted into the second space within the body to provide communication between the first and second spaces within the body; and a circumferential flange radially extending from the conduit proximate the first portion of the conduit, the flange configured to be implanted in the first space within the body adjacent an opening in a wall of the first space within the body, wherein a first length of a first portion of the circumferential flange on a first side of the conduit is longer than a second length of a second portion of the circumferential flange on a second opposite side of the conduit, the conduit extending at an angle to the flange and angled toward the first portion, wherein the first and second portions of the flange are pre-formed to form an angle to an imaginary plane passing through a region where the conduit and the flange are contiguous. - View Dependent Claims (13, 14, 15, 16)
