Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
158 words
An epicardial implantable defibrillator lead comprising: a loop system having a first end and a second end, the loop system comprising a sensor, a coil, and a closure segment comprising a perforation member and a sleeve; the coil comprising a generally tubular conductive portion defining a lumen, the lumen comprising an insulator, the insulator enclosing a conductor member, a memory member, or both; the sensor, coil, perforation member and sleeve being coupled in linear arrangement with the perforation member located proximal to the first end and the sleeve located proximal to the second end; and a connector system having a first end and a second end, the first end of the connector system coupled to the second end of the loop system, the second end adapted to be coupled to a pulse generator, the connector system comprising an insulating cover enclosing a conductor; the conductor passing through the connector system and connecting with either the coil or sensor.
Claim 2
Dependent Claim
158 words
An epicardial implantable defibrillator lead comprising: a loop system having a first end and a second end, the loop system comprising a sensor, a coil, and a closure segment comprising a perforation member and a sleeve; the coil comprising a generally tubular conductive portion defining a lumen, the lumen comprising an insulator, the insulator enclosing a conductor member, a memory member, or both; the sensor, coil, perforation member and sleeve being coupled in linear arrangement with the perforation member located proximal to the first end and the sleeve located proximal to the second end; and a connector system having a first end and a second end, the first end of the connector system coupled to the second end of the loop system, the second end adapted to be coupled to a pulse generator, the connector system comprising an insulating cover enclosing a conductor; the conductor passing through the connector system and connecting with either the coil or sensor.
Claim 3
Dependent Claim
13 words
The defibrillator lead of claim 1, wherein the lead is a pediatric lead.
Claim 4
Dependent Claim
23 words
The defibrillator lead of claim 2, wherein the loop system comprises three sensors and two coils, each coil being coupled to two sensors.
Claim 5
Dependent Claim
13 words
The defibrillator lead of claim 1, wherein the lead is an adult lead.
Claim 6
Dependent Claim
23 words
The defibrillator lead of claim 4, wherein the loop system comprises four sensors and three coils, each coil being coupled to two sensors.
Claim 7
Dependent Claim
20 words
The defibrillator lead of claim 1, wherein the sensor detects cardiac rhythm and paces a ventricle without penetrating the epicardium.
Claim 8
Dependent Claim
14 words
The defibrillator lead of claim 1, wherein the insulating cover comprises silicon or silastic.
Claim 9
Dependent Claim
22 words
The defibrillator lead of claim 1, wherein the perforation member and the sleeve, when connected retain the loop system as a loop.
Claim 10
Dependent Claim
41 words
The defibrillator lead of claim 8, wherein the perforation member comprises perforations therein for threading a suture therethrough and the lead further comprises a suture, wherein the suture threaded through the perforations is used to attach the lead to a patient.
Claim 11
Independent Claim
53 words
A method for implanting an epicardial implantable defibrillator lead in a patient in need thereof, the method comprising the steps of: making a transxiphoid or subxiphoid incision in the patient; accessing the pericardium; securing the lead to the diaphragmatic surface of the pericardium; advancing the lead into the pericardium; and closing the incision.
Claim 12
Independent Claim
53 words
A method for implanting an epicardial implantable defibrillator lead in a patient in need thereof, the method comprising the steps of: making a transxiphoid or subxiphoid incision in the patient; accessing the pericardium; securing the lead to the diaphragmatic surface of the pericardium; advancing the lead into the pericardium; and closing the incision.
Claim 13
Dependent Claim
20 words
The method of claim 10, the step of securing comprising: stitching the lead to the diaphragmatic surface of the pericardium.
Claim 14
Dependent Claim
18 words
The method of claim 10, the method further comprising the step of: forming a loop in the lead.
Claim 15
Dependent Claim
19 words
The method of claim 12, the step of forming comprising: tying or stitching together two portions of the lead.
Claim 16
Dependent Claim
30 words
The method of claim 13, wherein a single suture ties or stitches together the two portions of the lead and secures the lead to the diaphragmatic surface of the pericardium.
Claim 17
Dependent Claim
36 words
The method of claim 10, wherein the step of advancing comprises: positioning the lead in a region proximal to the apex of the heart, the AV groove, and the left and right borders of the heart.
Claim 18
Dependent Claim
33 words
The method of claim 10, wherein the step of advancing comprises: positioning the lead on the diaphragm in a region corresponding to the inferior surface of the heart in a generally horizontal plane.
Claim 19
Dependent Claim
29 words
The method of claim 10, further comprising the step of: implanting a pulse generator in the subclavicular area of the subject; and connecting the pulse generator to the lead.
Claim 20
Dependent Claim
16 words
The method of claim 17, wherein the pulse generator is implanted in the patient's left side.
Claim 21
Dependent Claim
16 words
The method of claim 17, wherein the pulse generator is implanted in the patient's right side.
