Abstract
Abstract The improved transvenous implantation method of the present invention involves entering a vein of a patient, translating through the vein to the patient's cardium atrium, anchoring onto the atrial lateral wall, puncturing the atrial lateral wall and forming a hole therein, exiting the atrium through the hole to the pericardial space and inserting the object into the pericardial space. The present invention also includes a method for the transvenous repair of a wound in the atrial lateral wall.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
79 words
In a patient, a method for the transvenous implantation of a device through a vein having a lumen into a pericardial space surrounding a cardium having an atrium and an atrial lateral wall comprising: entering the vein; translating through the vein lumen to the atrium; anchoring onto the atrial lateral wall; puncturing the atrial lateral wall and forming a hole therein; exiting the atrium through the hole to the pericardial space; and inserting the device into the pericardial space.
Claim 2
Dependent Claim
79 words
In a patient, a method for the transvenous implantation of a device through a vein having a lumen into a pericardial space surrounding a cardium having an atrium and an atrial lateral wall comprising: entering the vein; translating through the vein lumen to the atrium; anchoring onto the atrial lateral wall; puncturing the atrial lateral wall and forming a hole therein; exiting the atrium through the hole to the pericardial space; and inserting the device into the pericardial space.
Claim 3
Dependent Claim
21 words
The method of claim 1, wherein the anchoring is performed with a fixation catheter having an anchoring screw on the catheter.
Claim 4
Dependent Claim
14 words
The method of claim 1, wherein the anchoring is performed with a suction catheter.
Claim 5
Dependent Claim
14 words
The method of claim 1, wherein the anchoring is performed with a bioptome catheter.
Claim 6
Dependent Claim
13 words
The method of claim 1, wherein the puncturing is performed with a wire.
Claim 7
Dependent Claim
13 words
The method of claim 5, wherein the wire is a J-tip guide wire.
Claim 8
Dependent Claim
18 words
The method of claim 6, wherein the puncturing includes advancing the guide wire while simultaneously withdrawing the catheter.
Claim 9
Dependent Claim
13 words
The method of claim 1, wherein the puncturing further includes dilating the hole.
Claim 10
Dependent Claim
18 words
The method of claim 8, wherein the dilating is performed with a dilator advanced over a guide wire.
Claim 11
Dependent Claim
18 words
The method of claim 9, wherein the dilating is performed with a strippable sheath catheter over the dilator.
Claim 12
Dependent Claim
18 words
The method of claim 1, wherein the inserting is performed by advancing the device along a guide wire.
Claim 13
Dependent Claim
26 words
The method of claim 11, wherein the inserting further includes retracting the guide wire after advancing the device to a desired location within the pericardial space.
Claim 14
Dependent Claim
24 words
The method recited in claim 1 further comprising injecting fluid into the pericardial space after the inserting so as to expand the pericardial space.
Claim 15
Dependent Claim
77 words
In a patient, a method for the transvenous repair of a wound in the atrial lateral wall of a patient, through a vein having a lumen comprising: entering the vein; translating through the vein lumen to an atrium of the patient's cardium with a catheter; anchoring the catheter onto the atrial lateral wall over the wound; translating a blood clot through the catheter to the wound; compressing the blood clot into the wound; and removing the catheter.
Claim 16
Dependent Claim
77 words
In a patient, a method for the transvenous repair of a wound in the atrial lateral wall of a patient, through a vein having a lumen comprising: entering the vein; translating through the vein lumen to an atrium of the patient's cardium with a catheter; anchoring the catheter onto the atrial lateral wall over the wound; translating a blood clot through the catheter to the wound; compressing the blood clot into the wound; and removing the catheter.
