Cannulas, cannula mount assemblies, and clamping methods using such cannulas and cannula mount assemblies

A cannula for connecting an organ to a fluid flow system, comprising:

• a first portion having a first sealing surface;
• a first fitting on the first portion, the first fitting in fluid communication with a hole that is formed in the first sealing surface;
• and
• a second portion having at least one pair of opposing flexible arms arranged to engage the first portion, the second portion having a hole adapted to receive a section of tissue, the first and second portions adapted to secure the section of tissue when the first and second portions are brought together.

A cannula for connecting an organ to a fluid flow system, comprising:

• a cannula body having a first fitting;
• a portion extending from the cannula body that defines a lumen that is in fluid communication with the first fitting;
• and
• a second fitting on the cannula body, the second fitting in fluid communication with at least one of the first fitting and the lumen.

A cannula mount assembly, comprising:

• a cannula having at least one fitting that provides fluid communication with one of a hole and a lumen;
• a cannula mount adapted to support the cannula;
• at least one connection arm on one of the cannula and the cannula mount;
• and
• at least one arm holder on the other of the cannula and the cannula mount, the arm holder adapted to removably engage the connection arm.

A method for connecting an organ to a fluid flow system, comprising:

• providing a cannula adapted to be connected to a tissue of an organ and adapted to provide a fluid flow to the organ when connected to the tissue of the organ;
• securing the cannula to the tissue of the organ;
• providing a cannula mount adapted to engage and support the cannula;
• and
• engaging the cannula with the cannula mount after securing the cannula to the tissue of the organ.

A method for connecting an organ to a fluid flow system, comprising:

• providing a cannula adapted to be connected to a tissue of an organ and adapted to provide a fluid flow to the organ when connected to the tissue of the organ;
• positioning a first portion of the cannula and a second portion of the cannula relative to each other such that a first sealing surface on the first portion is substantially parallel to a second sealing surface on the second portion;
• and
• bringing the first and second portions of the cannula together, while maintaining the first sealing surface substantially parallel to the second sealing surface, to secure the cannula to the tissue of the organ.
