| 20090210251 | System and Method for Intelligent Management of Medical Care - A computerized medical care system provides validation of a diagnosis of a medical condition and requested medical services for treating the medical condition. The medial care system invokes multiple filters to determine the appropriateness of the diagnosis and medical service. Real time feedback is provided based on the determination. If the medical care cannot be validated, the feedback includes the reasons for the failure to validate, and any supporting materials for the lack of validation. The feedback may also prompt the requesting entity to provide additional information to help support the medical provider's position as to why the requested medical care is appropriate. | 08-20-2009 |

| 20090154705 | Apparatus and Method for Facilitating Cryptographic Key Management Services - A cryptographic key management system includes executable instructions to control access to keys based on permissions for users and groups. Executable instructions support cryptographic operations on the keys through a network application program interface. The cryptographic operations are controlled by the permissions. The cryptographic operations are distributed between the servers and the clients in accordance with criteria specifying optimal execution of cryptographic operations between the servers and the clients. | 06-18-2009 |
| 20100138927 | Apparatus and Method for Preventing Unauthorized Access to Secure Information - A computer readable storage medium includes executable instructions to process a duress command to invoke a system termination operation. The duress command may be a pass phrase with an added prefix or suffix. The duress command may be received from a menu, a dedicated key or a key sequence. The system termination operation may result in whole disk encryption. Alternately, the system termination operation may result in permanent destruction of data. | 06-03-2010 |

| 20100305462 | SYSTEM AND METHOD FOR SYNCHRONIZING ENERGY DELIVERY TO THE CARDIAC RHYTHM - A system for synchronizing application of treatment signals with a cardiac rhythm is provided. The system includes a memory that receives and stores a synchronization signal indicating that a predetermined phase such as R-wave of a cardiac rhythm of a patient has started. A synchronization module analyzes whether the stored synchronization signal is erroneous and if so, prevents a medical treatment device from applying a treatment energy signal such as an IRE pulse to a patient to take into account an irregular heart beat and noise in the synchronization signal in order to maximize safety of the patient. | 12-02-2010 |

| 20080275437 | CONNECTOR DEVICE FOR ELECTROPHYSIOLOGY PROBE - A flexible connector for securing an ablation probe in a looped configuration around the pulmonary veins of a heart includes a flexible base member having first and second apertures dimensioned to receive the ablation probe and wherein the flexible base member is slidable along a length of the ablation probe when the ablation probe is positioned within the first and second apertures. The flexible base member further includes a third aperture dimensioned to receive a looped portion of the ablation probe. The flexible connector is advanced along the length of the ablation probe to form a crossover point with the returning portion of the ablation probe. A tether is secured to the flexible base member and is used to withdraw or remove the flexible connector. | 11-06-2008 |

| 20080306335 | Endoscopic vessel harvesting system components - Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end. The tool for manipulating vessels may have a low-profile for increased visibility of operation, and may be coupled to the cannula with a damping mechanism to reduce the possibility of avulsion of the vessels. Various vessel cutting and sealing devices are provided that may accommodate various sizes of vessels and improve cutting and sealing efficacy. | 12-11-2008 |
| 20090118700 | METHOD FOR TREATING CORONARY VESSELS - A method is provided including introducing a delivery device through a vessel wall to a treatment site within one of a peri-adventitial space or a pericardium adjacent a coronary blood vessel and delivering a treatment agent through the delivery device. The treatment agent is delivered through the delivery device according to conditions that hydraulically dissect tissue planes within the peri-adventitial space. A kit is provided including a delivery device having a needle to be advanced through one of an epicardium of a heart and a wall of a coronary blood vessel into a peri-adventitial space and a treatment agent comprising particles having an average diameter on the order of 15 microns or more to be delivered through the delivery device into the peri-adventitial space. | 05-07-2009 |

| 20100004504 | EPICARDIAL CLIP - An epicardial clip for reshaping the annulus of the mitral valve of a heart. The epicardial clip includes a curved member having an anterior segment configured to be positioned in the transverse sinus of the heart, a posterior segment configured to be positioned on the posterior side of the heart, such as on or inferior to the atrioventricular groove, and a lateral segment extending between the anterior segment and the posterior segment. The lateral segment includes a curve such that the first end of the member is positioned at or above the plane of the mitral valve and the second end of the member is positioned at or below the plane of the mitral valve. | 01-07-2010 |

| 20090023986 | Vessel Harvesting - Apparatus and method for harvesting selected vessels in the body of a patient include manual manipulation of a rigid dissecting endoscope and the reconfiguration thereof to facilitate tissue dissection and tissue dilation in the formation of an anatomical space about the vessel within which side-branch vessels may be manipulated in preparation for severance and removal of the vessel from the anatomical space. | 01-22-2009 |
