摘要:
A vascular occlusive device which includes a vascular occlusive embolic coil, a bioactive coating disposed onto the embolic coil, and an outer barrier coating which serves to prevent a reaction between the bioactive agent in the bioactive coating and bodily fluids, until the outer barrier is activated by applying an external agent to the outer barrier.

The disclosed embodiments provide systems, devices and methods for providing a reward to a user of a mobile communications device. The described embodiments, for example, may include a mobile communications device that exchanges query data and response data with a computer system over a communications network. The computer system includes an evaluation application operable to determine a predetermined reward based on, at least in part, the received response data. The response data is received by the mobile communications device from the user in response to query data presented to the user by the mobile communications device. The predetermined reward, for example, may affect an operational characteristic of the mobile communications device on the wireless network. Also disclosed are systems, devices and methods that include an outcome application, associated with the computer system, that generates an outcome determination based on, at least in part, the response data.
摘要:
The present invention is directed to providing systems and methods for remotely monitoring sites to provide real-time information which can readily permit distinguishing false alarms, and which can identify and track the precise location of an alarm. In embodiments, monitoring capabilities such as intrusion/fire detection and tracking capabilities, can be implemented through the use of multistate indicators in an interface which permits information to be transmitted using standard network protocols from a remote site to a monitoring station in near real-time. In embodiments, communications can be handed from the centrally located host monitoring station to a mobile monitoring station (for example, a laptop computer in a responding vehicle, such as a police or fire vehicle). Additional embodiments include the measurement of environmental parameters such as temperature, carbon monoxide and differential air pressure to detect, monitor and manage a fire event. These measurements along with selected controllable output devices deployed in a space, such as sprinkler control valves and individually or zoned sprinkler heads, are used to initiate and control fire suppression technology both locally and remotely. For instance, a system of the present invention may detect a fire and cause a sprinkler system to disburse water in a facility.

A vascular occlusion device deployment system for placing an occlusion device at a preselected site within the vasculature of a patient. The deployment system employs a pusher including a gripper located at the distal end of the pusher to releasably retain a vascular occlusion device. The gripper is expanded by an expandable chemical reaction chamber so that the gripper releases the vascular occlusion device, thereby deploying the vascular occlusion device.

Embodiments of the invention provide a method, system and apparatus for centralized session management in an aggregated application environment. In one embodiment, a centralized session management method can include aggregating a set of applications in a host aggregation environment. Subsequently, each of the applications can be centrally kept alive so as to avoid a time out condition in any one of the applications so long as interactivity is detected within any one of the applications or within the host aggregation environment. In one aspect of the invention, the aggregating step can include aggregating a set of portlets in a portal environment.
摘要:
A clamp for grasping a major extent of rounded corner of a vehicle hatch or door opening, and providing an anchor-like extended grip by which re-positioning forces are evenly applied to the rounded corner. This grip assures that the entire curved corner retains or is returned to its original shape as it is adjusted into alignment with the rest of the opening. This in turn facilitates smooth and continuous replacement of the elastomeric weather seal around the opening to restore a completely functional seal about the hatch or door when it is closed.
摘要:
An expandable stent having a covering which exhibits the characteristic of upon being activated by applying an agent to the covering, dissolving to expose a portion of the underlying stent. The stent may be placed across the neck of an aneurysm to seal the aneurysm and thereafter a selected region of the covering may be dissolved by an activating agent to permit blood to flow to adjacent vessels.
摘要:
An expandable stent having a covering which exhibits the characteristic of being normally dissolvable in blood, but upon being activated, becomes inert to blood. The stent may be placed across the neck of an aneurysm to seal the aneurysm and thereafter the portion of the covering of the stent across the neck of the aneurysm is activated to become inert to blood and the balance of the covering dissolves to permit blood to flow to adjacent vessels.

The present invention provides an apparatus for sensing biometric information in a finger with piezo ceramic elements. In one embodiment, the apparatus includes an array of discrete piezo ceramic elements and filler. The array of discrete piezo ceramic elements is responsive to acoustic characteristics of parts of the finger. The filler is distributed between the discrete piezo ceramic elements and provides acoustic attenuation and electric isolation between the discrete piezo ceramic elements. A protective layer can receive a ridge pattern of the finger positioned proximate to the array. Air in valleys between ridges of the ridge patten of the finger acts as an acoustic barrier. A backing layer (air or foam) can also be provided.
摘要:
A method and apparatus for locating the injection point of an implanted medical device. In a preferred embodiment, the locating apparatus is in the form of radiopaque rings made of a metallic substance. When these rings are spaced apart at different heights on an implanted medical device, such as a drug port, a stereoscopic effect results from fluoroscopically viewing the device along an axis not parallel to the axis along which the rings are spaced. This effect allows one to readily determine the orientation of the device. This prevents accidental injection of drugs into the hard backside of the drug port.
