20100249909 | DEVICES, SYSTEMS AND METHODS TO TREAT HEART FAILURE - Several unique intracardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intracardiac pressure vents presented allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms but also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombus or other embolic material from entering the arterial circulation. In embodiments, the device comprises a core segment, an annular flange to engage one surface of the atrial septum and two other annular flanges to engage another surface of the atrial septum. | 09-30-2010 |

Specifically, the delivery system includes a delivery sheath, a delivery catheter, and a flexible or a rigid implant retention mechanism. The flexible implant retention mechanism includes an implant retention string having a fixed end and a free end where the free end extends from the fixed end, crosses a retention outlet of an implant, and extends proximally through a lumen of the delivery sheath. The rigid implant retention mechanism includes an implant retention wire having a fixed end and a free end where the free end extends from the fixed end, crosses a retention outlet of an implant, and extends proximally through a lumen of the delivery sheath. | 10-24-2013 |
20140277054 | DEVICES, SYSTEMS, AND METHODS FOR PERCUTANEOUS TRANS-SEPTAL PUNCTURE - The present teachings provide devices for puncturing the atrial septum percutaneously. Specifically, one aspect of the present teachings provides a trans-septal puncturing device comprising one or more of a locating element, a stabilizing element, a puncturing element, a safety element, and optionally a monitoring element, each of which is disposed in a lumen of a sheath. The locating element and the stabilizing element locate a desired puncture site and stabilize the trans-septal puncturing device at or near the site. The puncturing element of the trans-septal puncturing device has a limited puncturing distance due in certain instances to the safety element. The present teachings provide methods of using such device for percutaneously locating a fossa ovalis, stabilizing such device at the fossa ovalis, and piercing tissue across the fossa ovalis. | 09-18-2014 |
