20130158631 | AUTOMATIC POWER REGULATION FOR TRANSCUTANEOUS ENERGY TRANSFER CHARGING SYSTEM - Methods and systems for controlling power output from an external power source in a transcutaneous energy transfer (TET) system are provided to prevent inadvertent energy transfer when no secondary coil is present. The system operates by transmitting power transcutaneously from an external primary coil and determining whether a response from a secondary coil implanted within a patient is detected. If no response is detected, the power output of the primary coil is decreased. The decrease in power output can be accomplished by operating the primary coil at a lower average power level, which can include variations in power level, duty cycle, etc. The system can also be configured to periodically repeat the process in order to continue searching for a coupled secondary coil. | 06-20-2013 |
20130053622 | METHOD FOR SIMULTANEOUSLY DELIVERING FLUID TO A DUAL LUMEN CATHETER WITH A SINGLE FLUID SOURCE - One embodiment of the invention relates to an apparatus comprising an input connector configured for sterile connection to a fluid source, a first tube, a second, and a third tube. The first tube extends from a proximal end to a distal end comprising an input connector configured for sterile attachment to a fluid source. The input connector provides fluid communication between the first tube and the source. The second and third tubes are each in fluid communication with the first tube. The second and third tubes each extend from a proximal end to a distal end comprising an output connector configured for sterile connection to separate fluid input ports of a catheter based device. | 02-28-2013 |
20130046130 | LOADING GUIDE LUMEN - An apparatus is disclosed including: an intracardiac pump device having a path for a guidewire extending through the pump device from a first opening to a second opening; and a lumen which extends from a first end located outside of the pump device, into the pump device through the first opening in the pump device, along the path for the guidewire, out of the pump device through the second opening, and to a second end located outside of the pump device. The lumen is configured to receive the guidewire such that when the guidewire passes through the lumen from the first end to the second end, the guidewire is positioned along the path. | 02-21-2013 |
20130041205 | METHOD AND APPARATUS FOR PUMPING BLOOD - A pump system is disclosed for pumping blood from a patient's right atrium or right ventricle to a patient's pulmonary artery, the pump system including a distal section having at least one outlet; a pumping section in fluid communication with the distal section to provide blood to the outlet of the distal section, the pumping section having at least one inlet valve to receive blood; and a pump constructed and arranged to be positioned within the pumping section to draw blood into the pumping section in a first phase of operation and to pump blood out of the outlet of the distal section in a second phase of operation. | 02-14-2013 |

20120157755 | METHOD AND APPARATUS FOR ACCURATELY TRACKING AVAILABLE CHARGE IN A TRANSCUTANEOUS ENERGY TRANSFER SYSTEM - Improved devices and methods for tracking power consumption and available charge in a transcutaneous energy transfer (TET) system are provided. The method includes measuring the available charge in a battery and the current rate of power consumption in an implanted medical device, determining the remaining time before the charge level of the battery reaches a predetermined threshold level, and communicating the remaining time to a user. | 06-21-2012 |
20120157754 | COMPACT BATTERY AND CONTROLLER MODULE FOR A TRANSCUTANEOUS ENERGY TRANSFER SYSTEM - A compact implantable controller and battery module for a transcutaneous energy transfer (TET) system is provided having a single biocompatible housing encasing an energy storage device, a power control module, and a device control module. The power control module controls energy transfer to the storage device during charging and monitors power consumption of a cardiac assist device. The device control module controls and monitors the operation of a cardiac assist device. | 06-21-2012 |
20120157753 | TRANSCUTANEOUS ENERGY TRANSFER SYSTEM WITH MULTIPLE SECONDARY COILS - A transcutaneous energy transfer (TET) system is provided having a plurality of secondary coils adapted for disposition in a patient, at least one primary coil configured to transmit transcutaneous energy, and a controller adapted for disposition in a patient. The controller includes circuitry to isolate the secondary coils from each other and direct electric current from at least one of the secondary coils to a charge storage device and/or implantable medical device. | 06-21-2012 |

20090264820 | METHOD AND APPARATUS FOR IMPLANTING AN ENDOLUMINAL PROSTHESIS SUCH AS A PROSTHETIC VALVE - Balloon catheters, and medical devices including balloon catheters, are provided that comprise a balloon assembly disposed at the distal end of an elongated tubular member. The balloon, when in the inflated state, includes a body fluid lumen that extends longitudinally through the balloon and is open at the proximal end of the balloon and the distal end of the balloon. In some aspects, the outer surface of the balloon is contiguous from the proximal end to the distal end of the balloon when the balloon is inflated. In other aspects, an endoluminal prosthesis, for example, a stent that can optionally include a prosthetic valve, surrounds the balloon assembly and is adjacent to the outer surface of the balloon. In still other aspects, endoluminal prosthesis implant devices are provided that are suitable for implanting an endoluminal prosthesis in a body vessel containing a flowing fluid such as a vessel in the heart, e.g., the left or right ventricle inflow or outflow tracks. The endoluminal prosthesis implant devices include a balloon assembly and an endoluminal prosthesis surrounding the balloon assembly. The balloon assembly is configured to permit a fluid to pass from the first end of the balloon to the second end of the balloon when the balloon is in an inflated state. In some embodiments of all of these aspects, the balloon is configured to prevent a fluid from passing from the second end of the balloon to the first end of the balloon when the balloon is in an inflated state. In some embodiments, for example, the body fluid lumen includes a body fluid lumen valve moveable between a first position and a second position. The body fluid lumen valve occludes the body fluid lumen to a greater extent in the first position than in the second position. In some embodiments, the body fluid lumen valve substantially prevents a fluid from flowing through the body fluid lumen in a first direction. Certain aspects and/or embodiments of the balloon catheters, and medical devices including balloon catheters, may allow for the deployment of an endoluminal prosthetic valve (e.g., a heart valve), while the native valve can continue to function uninterrupted under its native load and flow. | 10-22-2009 |
