Abstract: A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.

Abstract: The stent graft includes a main body and an external coupling. The main body extends along a longitudinal axis and includes proximal and distal ends. The external coupling extends away from the main body and defines an opening having a center. The main body includes a first bracketing stent extending about a proximal side of the external coupling. The first bracketing stent includes first and second peaks. The first peak is circumferentially aligned with the center of the external coupling. The first peak is proximal the second peak about the main body along the longitudinal axis.

Abstract: A stent graft includes a main body extending along a longitudinal axis when in a preinstalled configuration prior to insertion into a body of a patient. The stent graft also includes a mobile external coupling extending away from the main body and configured to align with a secondary blood vessel within the body to provide access thereto. The main body includes a plurality of stents extending thereabout. The stents include a first bracketing stent extending about a proximal side of the mobile external coupling, and a second bracketing stent located adjacent the first bracketing stent and extending about a distal side of the mobile external coupling. The first bracketing stent includes peaks that are aligned along a first axis, and the second bracketing stent includes peaks that are aligned along a second axis that diverges from the first axis relative to a circumferential direction toward the mobile external coupling.

Abstract: A delivery system for delivering a prosthesis includes a catheter and a selectable tip kit having a plurality of tips. Each tip is uniquely shaped, i.e., has a particular shape different than the shape of all the other tips, and each tip is better suited for some procedures than for others. One of the tips is selected by the physician as being particularly well suited for the procedure to be performed. The selected tip is non-removably attached to the catheter and the remaining tips are discarded. This allows the delivery system to be customizable to each procedure, putting the physician in control of the case. This provides a case specific delivery system for the physicians to use and at a very low expense and with minimal additional engineering.

Abstract: A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.

Abstract: Techniques for implementing a publish-subscribe messaging system are disclosed. An example device generates a topic string comprising a string of characters that represent a subscription to a requested publication. A subscription filter is computed based on the topic string. The device is configured to receive a publication, which includes a data payload and a publication filter. The device performs a bitwise comparison of the subscription filter and the publication filter to determine whether the publication is a destination match for the subscription. If the publication is a destination match for the subscription, the device consumes the data payload of the publication.

Abstract: Various embodiments provide systems and methods for connecting wireless-enabled products to wireless networks. Customer network credentials may be stored in a server along with a customer identifier (“customer ID”) during one-time registration. When a wireless-enabled product is purchased, a product identifier (“product ID”) and the customer's ID are forwarded to the server, which correlates the two identifiers, linking the purchased product to the customer. When the wireless-enabled product is powered on, the product accesses the server via a public network connection, and sends the product ID and a security token to the server. The server uses the product ID and the security token to authenticate the product. Once authenticated, the server uses the correlated customer ID to look up the network credentials for the customer's private network, and provides the network credentials to the wireless-enabled product.

Abstract: An audio output device maintains a collection of policies, and concurrently receives multiple audio streams over a wireless network. The wireless device re-streams a first audio stream of the multiple audio streams to a second audio output device of one or more other audio output devices, based at least in part on (i) an audio type of the first audio stream, and (ii) a policy in the collection of policies for the audio type.

Abstract: An audio output device that operates on a network to connect with a first source device. The connection to the first source device can be made using a first wireless port, so that the first source device streams a first audio content to the first wireless port of the audio output device. When connected to the first source device, the audio output device generates an advertisement for the network, which communicates that the audio output device is available to receive a connection to another source device. In this way, the audio output device generates a new wireless port to connect to a second source device when the connection with the first source device is active.

Abstract: Using Bluetooth to provide the network management functions such as device discovery, service discovery, security negotiation, and connection establishment. Upon a Bluetooth connection being established between the Bluetooth-enabled devices an IP channel availability query is made. This is accomplished by using information request signals from the Bluetooth L2CAP protocol layer. If an IP channel is available on both the devices and the communication modules using that IP channel are compatible the devices will then establish a secondary Internet Protocol (IP) based data channel between them.
