Single port cardiac support apparatus
First Claim
1. A system for providing cardiac support during surgery, comprising:
- a blood pump having an inlet port and an outlet port that are coaxially aligned;
a first conduit having a proximal opening and a distal opening, the proximal opening being sized and configured to be coupled to the inlet port of the blood pump, and the first conduit being sized and configured such that the distal opening may extend into a heart chamber or vessel;
a second conduit having a proximal opening and a distal opening, the proximal opening being sized and configured to be coupled to the outlet port of the blood pump, and the second conduit being disposed generally coaxially relative to the first conduit and sized and configured such that the distal opening of the second conduit is spaced-apart from the distal end of the first conduit within the heart or vessel;
at least one inflatable member disposed along at least one of the first conduit and the second conduit; and
a fluid source capable of inflating the inflatable member.

Abstract
A minimal intrusive cardiac support apparatus is disclosed which requires only one incision into a main blood vessel or heart chamber. The apparatus includes a pair of generally coaxial and slideably arranged cannulae (one inner and one outer) communicatively coupled to a blood pump for providing right-heart and/or left-heart cardiac support during cardiac surgery. Optional balloons may be mounted on the outside of the inner and outer conduits which can be selectively inflated to seal off the sides surrounding vessel or to deliver cooling fluid or medication to the surrounding tissue. Using the apparatus, a method of pumping blood through the body is also disclosed.
