20100262168 | SEALING AND FILLING VENTRICULAR PARTITIONING DEVICES TO IMPROVE CARDIAC FUNCTION - Described herein are partitioning devices for reducing ventricular volume that may be secured within a ventricle and separate it into a productive portion and a non-productive portion. The partitioning devices described herein may include a reinforced membrane and may be secured within the heart chamber by sealing them to the wall of the heart chamber, for example, by inflating an inflatable element on the periphery of the device. All or a region of the non-productive portion formed by these devices may be enclosed within a container or bag. The non-productive portion may be filled with a material, including occlusive materials (e.g., vasoclusive coils). Sealing and/or filling the non-productive portion formed by the devices described herein may help prevent leakage from the non-productive region. Also described herein are systems including these devices and methods of using them, which may be suitable for treating patients with heart disease, particularly congestive heart failure. | 10-14-2010 |
20110087066 | DEVICES AND METHODS FOR DELIVERING AN ENDOCARDIAL DEVICE - Described herein are systems for partitioning a ventricle of a heart. The systems may include a partitioning device or implant, and an applicator for inserting, repositioning and/or removing the partitioning device. The implant may support the ventricle wall and may reduce the volume of the ventricle. In particular, described herein are systems for delivering and deploying a partitioning device into a ventricle. The delivery system may include a catheter having a distal coupling element for coupling to a partitioning device in a collapsed configuration; the catheter may also have an expansion member for applying force to the partitioning device to fully expand it into a deployed configuration and to secure or seal it against the ventricle wall. | 04-14-2011 |
20110098525 | VENTRICULAR VOLUME REDUCTION - Devices and systems including implants (which may be removable) and methods of using them for reducing ventricular volume. The implants described herein are cardiac implants that may be inserted into a patient's heart, particularly the left ventricle. The implant may support the heart wall, or may be secured to the heart wall. The implants are typically ventricular partitioning device for partitioning the ventricle into productive and non-productive regions in order to reduce the ventricular volume. | 04-28-2011 |
20120238996 | METHODS OF TREATING CARDIAC ARRHYTHMIA - Methods and apparatus of embodiments of the invention are adapted to treat tissue inside a patient's body. Aspects of the invention can be used in a wide variety of applications, but certain embodiments provide minimally invasive alternatives for treating atrial fibrillation by delivering a tissue-damaging agent to selected areas of the heart. One exemplary embodiment of the invention provides a method of treating cardiac arrhythmia. This method includes positioning a distal tissue-contacting portion of a body in surface contact with a tissue surface of cardiac tissue; detecting the surface contact between the tissue-contacting portion and the tissue surface; and thereafter, injecting a tissue-ablating agent into the cardiac tissue through the tissue-contacting portion of the body. | 09-20-2012 |
20130274595 | DEVICES AND METHODS FOR DELIVERING AN ENDOCARDIAL DEVICE - Described herein are devices, systems and methods for delivering an endocardial device. The systems for delivering the device transvascularly may generally include an elongate guide catheter having a proximal end and a distal end; a conical dilator at the distal end of the elongate guide catheter, the conical dilator being removable to enable delivery of the ventricular portioning device; a delivery catheter having a proximal and distal end; an expansion member near the distal end of the delivery catheter and configured to expand a plurality of struts of the partitioning device; and a coupling element configured to deployably secure to a hub of the partitioning device. The systems for delivering the device transapically may generally include an elongate access sheath; an elongate delivery catheter; an expansion member; and a coupling element proximal to the expansion member and configured to deployably secure to a hub of the partitioning device. | 10-17-2013 |
