Abstract
Abstract A cardioplegia occluder and methods of using the device during cardiac surgery are disclosed. The system typically includes a substantially rigid cannula with an occluder mounted on the distal region of the cannula that expands upon activation to occlude the aorta downstream of an infusion port which delivers cardioplegia solution to arrest the heart. Systems including cutting blades, blade guards, flanges, radiopaque markers and occluder aligners are also disclosed. In use, the distal end of the cannula is inserted through an incision into the aorta, the occluder is expanded and cardioplegia solution is infused upstream of the aorta to arrest the heart. The infusion port can alternately be used to aspirate cardioplegia or embolic debris or other unwanted material from the aorta.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
50 words
A method for cannulation, comprising the steps of: inserting a distal end of a cannula into an aorta; inserting a filter through a lumen of the cannula and past the distal end of the cannula; deploying the filter; and expanding an occluder associated with the distal end of the cannula.
Claim 2
Independent Claim
50 words
A method for cannulation, comprising the steps of: inserting a distal end of a cannula into an aorta; inserting a filter through a lumen of the cannula and past the distal end of the cannula; deploying the filter; and expanding an occluder associated with the distal end of the cannula.
Claim 3
Dependent Claim
17 words
The method of claim 1 , further comprising the step of making an incision in the patient.
Claim 4
Dependent Claim
13 words
The method of claim 1 , wherein the occluder is a balloon occluder.
Claim 5
Dependent Claim
13 words
The method of claim 1 , wherein the occluder is a cardioplegia occluder.
Claim 6
Dependent Claim
25 words
The method of claim 1 , wherein the occluder comprises a catheter having an expandable occluder device mounted on a distal end of the catheter.
Claim 7
Dependent Claim
23 words
The method of claim 4 , wherein the occluder further comprises a lumen communicating with a cardioplegia port distal to the occlusion device.
Claim 8
Independent Claim
50 words
A method for cannulation, comprising the steps of: inserting a distal end of a cannula into cardiac tissue; inserting a filter through a lumen of the cannula and past the distal end of the cannula; deploying the filter; and expanding an occluder associated with the distal end of the cannula.
Claim 9
Independent Claim
50 words
A method for cannulation, comprising the steps of: inserting a distal end of a cannula into cardiac tissue; inserting a filter through a lumen of the cannula and past the distal end of the cannula; deploying the filter; and expanding an occluder associated with the distal end of the cannula.
