Abstract: Systems and methods are described for utilizing a secure environment on a mobile computing device for applying policy-based decision management in response to access requests from untrusted areas. A policy decision processor (PDP) within the secure environment provides a policy decision in response to an access query. A decision cache within the secure environment can be used to store policy decisions for faster resolution of access requests. Policy enforcement points (PEPs) are placed between external devices that are trying to access the device and the secured environment, where the PEPs are used to enforce the policy-based decision, and can be located either inside or outside the secure environment. Decision certificates can be formulated using validity information and timestamps, and used for validation policy certificates. Memory in non-secure areas can also be marked (colored) for use in performing trusted operations in order to optimize system resource usage.

Abstract: A system and devices for ablation and removal of occlusions from blood vessels is provided. Laser culling systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Catheter systems comprise distal end features adapted to cut and remove al least portions of an occlusion that generally correspond to dimensions of an inner lumen of a catheter.

Abstract: Lead tip removal is accomplished by first stabilizing an area around the lead tip attachment site in the heart wall. A balloon located at the tip of the lead when inflated expands substantially perpendicular to the lead, stabilizing the area around the lead tip. Upon further inflation, the balloon expands substantially parallel with the lead, causing the lead tip to pull away from the heart wall. In another embodiment, a sheath is inserted over the lead and advanced to the heart wall. A passive or active stabilization device is attached to the sheath tip to stabilize the area around the lead tip. In another embodiment, a balloon is located at the tip of the sheath that, when inflated, expands substantially perpendicular to the lead, stabilizing the area around the lead tip. The lead tip is removed with less force due to the stabilization provided to the lead tip area.

Abstract: This disclosure discusses various methods and devices for capturing plaque that is to be removed from a blood vessel after the plaque has been separated from the blood vessel or remaining plaque.

Abstract: A system and method for policy-based active Data Loss Prevention (DLP) using a two-step process to first determine if an attempt to access a data object is governed by DLP policy, and if so, then applying the DLP policy to either allow or deny access. Attempts by an agent to access, create, modify, or distribute a data object are trapped by a policy execution point. A first query determines if DLP policies govern that access request. If they do, then the metadata is decrypted to form a second query to a policy decision point to adjudicate the access request. If the access request is allowed, then a second key is provided to decrypt the data object for further processing. The system further provides for the encryption of unencrypted data objects to protect them for all future access queries.

Abstract: Catheter devices for ablation and removal of occlusions from blood vessels and methods of using the same are provided. Catheter devices are useful to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Distal features of the catheter devices comprise arrangements of laser ablative or mechanical cutting features that generally provide enhanced surface areas and cutting functions. Spiral or helical arrangements are provided to aid in cutting operations.

A sensor is adapted to detect transmission of laser energy through at least one of the plurality of transport members.

Abstract: A preferred contact group centric interface for a communication device can be used to facilitate communications by a user. The user interface can be arranged to activate from a user's “home page” on the display, from an idle screen that is accessed after a timeout period expires, or any other appropriate mechanism that activates the preferred contact group centric experience. A user selects the preferred contact group from among an array of the user's contacts. Once the contact group is configured, a minimal number of navigation/selection features is necessary to activate any number of communication modes available to the contacts. The contact group is configured such that simple and quick navigation between the contact members is achieved. The contact group can be presented in 2D and 3D arrangements, in any number of list or geometric configurations. A pricing plan can optionally be tied to each member of the contact group.

Abstract: Systems and methods for using Near Field Communications1 (NFC) m\d other short-range wireless communications technologies in mobile device management and security. Uses of NFC devices of both passive and active types are presented herein, as “policy control points” (PCPs) within a policy-based system for mobile handset management, in situations where granular control of handset capabilities is required. Certain location-based, as well as non-location-specific variants of the invention are presented as examples.

Abstract: An autonomous and adaptive method and system for secure, policy-based control of remote and locally controlled computing devices. The invention uses a policy-based access control mechanism to achieve adaptive and dynamic behavior modification based on the context of the local operating environment of the computing device. The modification system assesses the desirability of actions or outcomes as determined by the policy rules and modifies them accordingly, thus altering the behavior of the computing device. The system can utilize a machine learning technique, pattern matching and heuristic evaluation. When applied to the control of robotic and autonomous devices, the system allows the robot to offload adjudication to a remote system and also facilitates cooperative behaviors between robots operating in dynamic environments.
