Abstract
Abstract An occluder apparatus for obstructing the flow of blood in a blood vessel has an elongated hollow tubular body having a leading end sized for reception in the blood vessel and includes portion of the body fabricated from a material soluble in blood, and a piercing device for inserting the body through the wall of the blood vessel to extend the leading end into the interior of the blood vessel. An inflatable diaphragm is carried by the body in a collapsed, deflated condition, and the apparatus includes a passage for conducting an inflating fluid from an external source, which is into fluid communication with the interior of the diaphragm, to effect expansion the diaphragm. Elongated openings in the body enable the diaphragm to be released in an inflated state from the body into flexible occluding engagement with the interior wall of the blood vessel about the full circumference of a transverse section thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A system for occluding a patent's ascending aorta, delivering oxygenated blood from a heart-lung machine and perfusing myocardial protection solution into the patient's aortic root, the system comprising: an aortic occlusion device including a tubular portion adapted for insertion through a wall of the ascending aorta and having a blood flow lumen, an occluding member, and a myocardial protection solution flow lumen, wherein the blood flow lumen is coupled to a heart-lung machine for returning oxygenated blood to the patient, the occluding member is movable from a collapsed position to an expanded position, the occluding member occludes the patient's ascending aorta when in the expanded position; and a source of myocardial protection solution for protecting the patient's heart when the patient's heart is arrested, the source of myocardial protection solution being fluidly coupled to the myocardial protection solution flow lumen for infusing the myocardial protection solution into the patient's ascending aorta, wherein the occluding member is positioned inside the tubular portion when in the collapsed condition and extending axially from the tubular portion to occlude the aorta when in the expanded condition.
Claim 2
Independent Claim
182 words
A system for occluding a patent's ascending aorta, delivering oxygenated blood from a heart-lung machine and perfusing myocardial protection solution into the patient's aortic root, the system comprising: an aortic occlusion device including a tubular portion adapted for insertion through a wall of the ascending aorta and having a blood flow lumen, an occluding member, and a myocardial protection solution flow lumen, wherein the blood flow lumen is coupled to a heart-lung machine for returning oxygenated blood to the patient, the occluding member is movable from a collapsed position to an expanded position, the occluding member occludes the patient's ascending aorta when in the expanded position; and a source of myocardial protection solution for protecting the patient's heart when the patient's heart is arrested, the source of myocardial protection solution being fluidly coupled to the myocardial protection solution flow lumen for infusing the myocardial protection solution into the patient's ascending aorta, wherein the occluding member is positioned inside the tubular portion when in the collapsed condition and extending axially from the tubular portion to occlude the aorta when in the expanded condition.
Claim 3
Dependent Claim
17 words
The system of claim 1, further comprising: a heart-lung machine fluidly coupled to the blood flow lumen.
Claim 4
Dependent Claim
23 words
The system of claim 1, wherein: the pressure sensing means includes a pressure lumen and a pressure sensor coupled to the pressure lumen.
Claim 5
Dependent Claim
15 words
The system of claim 1, wherein: the aortic occlusion device has a conical distal end.
Claim 6
Dependent Claim
27 words
The system of claim 1, wherein: the aortic occlusion device has a distal end, the distal end having a cutting element for incising the patient's ascending aorta.
Claim 7
Dependent Claim
24 words
The system of claim 5, wherein: the cutting element is movable to a position away from the distal end of the aortic occlusion device.
Claim 8
Independent Claim
176 words
A system for occluding a patient's ascending aorta, delivering oxygenated blood from a heart-lung machine and perfusing myocardial protection solution into the patient's aortic root, the system comprising: an aortic occlusion device having an occluding flow lumen, a balloon, and a lumen, an outlet coupled to the lumen, and a blood flow outlet coupled to a heart-lung machine for returning oxygenated blood to a patient, wherein the occluding member is movable from a collapsed position to an expanded position, the occluding member occludes the patient's ascending aorta when in the expanded position, the occluding member has a toroidal shaped portion defining a central portion of the device; and a source of myocardial protection solution for protecting the patient's heart when the patient's heart is arrested, the source of myocardial protection solution being fluidly coupled to the lumen, wherein the blood flow outlet is positioned at the central portion, such that the blood flow outlet is surrounded by the toroidal shaped portion of the occluding member and is substantially perpendicular to a longitudinal axis of the aorta.
Claim 9
Independent Claim
176 words
A system for occluding a patient's ascending aorta, delivering oxygenated blood from a heart-lung machine and perfusing myocardial protection solution into the patient's aortic root, the system comprising: an aortic occlusion device having an occluding flow lumen, a balloon, and a lumen, an outlet coupled to the lumen, and a blood flow outlet coupled to a heart-lung machine for returning oxygenated blood to a patient, wherein the occluding member is movable from a collapsed position to an expanded position, the occluding member occludes the patient's ascending aorta when in the expanded position, the occluding member has a toroidal shaped portion defining a central portion of the device; and a source of myocardial protection solution for protecting the patient's heart when the patient's heart is arrested, the source of myocardial protection solution being fluidly coupled to the lumen, wherein the blood flow outlet is positioned at the central portion, such that the blood flow outlet is surrounded by the toroidal shaped portion of the occluding member and is substantially perpendicular to a longitudinal axis of the aorta.
Claim 10
Dependent Claim
