Abstract:
A method of performing a medical procedure, comprising the steps of:a) providing a perfusion cannula comprising an elongated shaft having a distal shaft section implanted within a body lumen having a closed proximal end, a distal end and a port in the distal end of the distal shaft section; and a proximal shaft section having a proximal and distal end, the distal end implanted within a body lumen and which is connected to the distal shaft section at a location between the proximal and distal ends of the distal shaft section, such that an acute angle is formed at the location at which the proximal shaft section is connected to the distal shaft section, the acute angle being between the proximal shaft section and a proximal portion of the distal shaft section; and a lumen in the elongated shaft which extends within the proximal shaft section and within at least a portion of the distal shaft section to and in fluid communication with the port in the distal end of the distal shaft section; b) inserting the distal shaft section through an incision in a patient's blood vessel and into the blood vessel at a location distal to an occlusion in the blood vessel, so that a section of the blood vessel at a proximal end of the incision therein is located between and in contact with the proximal shaft section and the proximal portion of the distal shaft section; and c) connecting the proximal end of the perfusion cannula to a source of perfusion fluid, so that perfusion fluid flows from the proximal shaft section to the distal shaft section and out the port in the distal end of the distal shaft section.
