Abstract
Abstract A method for diagnosing and treating anticipated cardiac rupture and an apparatus for the same. Anticipated cardiac rupture is diagnosed by examining one or more of several predictive symptoms, including pericarditis, repetitive unprovoked emesis, restlessness and agitation, abnormal ECG ST segments and T waves, and abrupt hypotension and bradycardia. The treatment includes the adhesion of a mesh patch to the myocardium by introducing the patch into the pericardia sac through an endoscope, applying the patch to the myocardium using a pair of graspers, and adhering the patch to the myocardium by applying a cyanoacrylate glue to the patch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A medical treatment method for a myocardium enclosed in a pericardial sac, comprising: determining whether a patient who has experienced an acute infarction of the myocardium has at least one of pericarditis, repetitive unprovoked emesis, restlessness or agitation, a ST segment elevation or T wave pattern in an electrocardiogram that is different than normal postinfarction pattern, or abrupt hypotension and bradycardia; correlating said determination with the likelihood of a patient developing cardiac rupture; and applying and adhering a patch to the myocardium to prevent said cardiac rupture; wherein inserting the patch through a first instrument channel in a flexible endoscope from outside the patient to inside the pericardial sac.
Claim 2
Dependent Claim
109 words
A medical treatment method for a myocardium enclosed in a pericardial sac, comprising: determining whether a patient who has experienced an acute infarction of the myocardium has at least one of pericarditis, repetitive unprovoked emesis, restlessness or agitation, a ST segment elevation or T wave pattern in an electrocardiogram that is different than normal postinfarction pattern, or abrupt hypotension and bradycardia; correlating said determination with the likelihood of a patient developing cardiac rupture; and applying and adhering a patch to the myocardium to prevent said cardiac rupture; wherein inserting the patch through a first instrument channel in a flexible endoscope from outside the patient to inside the pericardial sac.
Claim 3
Dependent Claim
59 words
The method of claim 1, wherein the endoscope further includes at least one light channel and a viewing channel, and wherein the step of inserting the patch includes wrapping it around a flexible inserter, inserting one end of the inserter with the wrapped patch through the first instrument channel and unwrapping it from the inserter within the pericardial sac.
Claim 4
Dependent Claim
71 words
The method of claim 2, wherein the inserter is a first grasper with first grasper grasping jaws on the end inserted into the first instrument channel, wherein the endoscope further includes a second instrument channel, wherein a second grasper with second grasped grasping jaws on one end is inserted into the second instrument channel, and further comprising unfurling the patch within the pericardial sac using the first grasper and second grasper.
Claim 5
Dependent Claim
71 words
The method of claim 1, wherein the endoscope includes an air insufflation channel and an air desufflation channel, and further comprising flowing air out of one of the air insufflation channel and air desufflation channel and onto the myocardium and off of the myocardium and into the other of the air insufflation channel and air desufflation channel, in order to dry a surface of the myocardium for application of said patch.
Claim 6
Dependent Claim
24 words
The method of claim 4, further comprising producing an air pocket in the pericardial sac using the air insufflation channel and air desufflation channel.
Claim 7
Dependent Claim
17 words
The method of claim 1, further comprising adhering the patch to the myocardium with a cyanoacrylate glue.
Claim 8
Dependent Claim
41 words
The method of claim 6, further comprising applying the cyanoacrylate glue by inserting a catheter through one of the first instrument channel and second instrument channel, and flowing the cyanoacrylate glue through said catheter into the pericardial sac onto the myocardium.
Claim 9
Dependent Claim
46 words
The method of claim 7, wherein the patch is a mesh material, and the patch is adhered to the myocardium by applying it to the myocardium and then applying the cyanoacrylate glue over it so that the glue flows through the mesh and onto the myocardium.
Claim 10
Dependent Claim
25 words
The method of claim 1, further comprising determining a site of an anticipated cardiac rupture based on the ST segment elevation or T wave pattern.
