Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
58 words
A process for treatment of cardiac arrhythmia in a human heart comprising introducing a medical device for performing ablation procedures into a pulmonary vein, and forming a circumferential lesion in tissue adjacent to or within the pulmonary vein using the medical device, wherein the circumferential lesion is formed at least partially in an os of the pulmonary vein.
Claim 2
Dependent Claim
58 words
A process for treatment of cardiac arrhythmia in a human heart comprising introducing a medical device for performing ablation procedures into a pulmonary vein, and forming a circumferential lesion in tissue adjacent to or within the pulmonary vein using the medical device, wherein the circumferential lesion is formed at least partially in an os of the pulmonary vein.
Claim 3
Dependent Claim
42 words
The process of claim 1 further comprising at least substantially sealing the pulmonary vein by use of a seal member secured to the medical device to prevent substantially a flow of blood through the pulmonary vein prior to forming the circumferential lesion.
Claim 4
Dependent Claim
12 words
The process of claim 2 wherein the seal member comprises a balloon.
Claim 5
Dependent Claim
27 words
The process of claim 2 further comprising introducing conductive media into the pulmonary vein from the medical device after the pulmonary vein is at least substantially sealed.
Claim 6
Dependent Claim
26 words
The process of claim 4 further comprising conducting energy from the medical device to the os of the pulmonary vein by use of the conductive media.
Claim 7
Dependent Claim
36 words
The process of claim 4 further comprising introducing a second medical device to a location associated with the pulmonary vein proximal from the first medical device, wherein the conductive media flows around the second medical device.
Claim 8
Dependent Claim
27 words
The process of claim 6 further comprising conducting energy from the first medical device to the os of the pulmonary vein by use of the conductive media.
Claim 9
Dependent Claim
21 words
The process of claim 6 wherein the second medical device is secured to the first medical device and comprises a balloon.
Claim 10
Dependent Claim
34 words
The process of claim 2 further comprising steering the medical device to a location within the pulmonary vein by use of the seal member after the medical device is introduced in the pulmonary vein.
Claim 11
Dependent Claim
18 words
The process of claim 1 wherein the circumferential lesion is formed by the continuous application of ablative energy.
Claim 12
Dependent Claim
101 words
A process for the ablation of tissue associated with an os of a pulmonary vein of a human heart comprising introducing a medical device containing a seal member through a chamber of the heart into the pulmonary vein, at least substantially sealing the pulmonary vein to prevent substantially a flow of blood through the pulmonary vein by use of the seal member, introducing an ablation member for ablating the tissue associated with the os of the pulmonary vein into the pulmonary vein, and ablating tissue at least partially within the os of the pulmonary vein by use of the ablation member.
Claim 13
Dependent Claim
101 words
A process for the ablation of tissue associated with an os of a pulmonary vein of a human heart comprising introducing a medical device containing a seal member through a chamber of the heart into the pulmonary vein, at least substantially sealing the pulmonary vein to prevent substantially a flow of blood through the pulmonary vein by use of the seal member, introducing an ablation member for ablating the tissue associated with the os of the pulmonary vein into the pulmonary vein, and ablating tissue at least partially within the os of the pulmonary vein by use of the ablation member.
Claim 14
Dependent Claim
34 words
The process of claim 11 further comprising steering the medical device to a location within the pulmonary vein by use of the seal member after the medical device is introduced in the pulmonary vein.
Claim 15
Dependent Claim
12 words
The process of claim 11 wherein the seal member comprises a balloon.
Claim 16
Dependent Claim
17 words
The process of claim 11 wherein the tissue is ablated using a continuous application of ablative energy.
Claim 17
Dependent Claim
69 words
A process for treatment of cardia arrhythmia in a human heart comprising introducing a medical device for performing ablation procedures into a pulmonary vein, at least substantially sealing the pulmonary vein to prevent substantially a flow of blood through the pulmonary vein by use of a seal member, and forming a circumferential lesion at least partially in tissue in an os of the pulmonary vein using the medical device.
Claim 18
Dependent Claim
69 words
A process for treatment of cardia arrhythmia in a human heart comprising introducing a medical device for performing ablation procedures into a pulmonary vein, at least substantially sealing the pulmonary vein to prevent substantially a flow of blood through the pulmonary vein by use of a seal member, and forming a circumferential lesion at least partially in tissue in an os of the pulmonary vein using the medical device.
Claim 19
Dependent Claim
12 words
The process of claim 15 wherein the seal member comprises a balloon.
Claim 20
Dependent Claim
27 words
The process of claim 16 further comprising conducting energy from the medical device through the conductive media to a surface of the os of the pulmonary vein.
Claim 21
Dependent Claim
20 words
The process of claim 15 further comprising introducing conductive media into the pulmonary vein prior to forming the circumferential lesion.
Claim 22
Dependent Claim
42 words
The process of claim 18 further comprising introducing a second medical device secured to the first medical device to a location associated with the pulmonary vein proximal from the first medical device, wherein the conductive media flows around the second medical device.
Claim 23
Dependent Claim
34 words
The process of claim 15 further comprising steering the medical device to a location within the pulmonary vein by use of the seal member after the medical device is introduced in the pulmonary vein.
