A system is disclosed, for administering a therapeutic agent locally and to a depth within cardiac tissue. An elongate, flexible catheter contains a flexible electric conductor and supports at its distal end an implantable electrode incorporating a penetrating element, typically a fixation helix or a linear needle that penetrates cardiac tissue as the electrode is implanted. A therapeutic agent is delivered through the electrode, to the cardiac tissue surrounding the penetrating element. The electrode can act as a sensor to monitor an electrical condition of the surrounding cardiac tissue and to control delivery of the agent responsive to the sensed electrical condition. Several embodiments feature a distal reservoir adjacent the electrode, for effecting transient deliveries of the therapeutic agent in minute quantities. Other embodiments are disclosed for providing sustained deliveries of agents.

The fuel supply system is provided for an internal combustion engine of a vehicle.

An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.

Disclosed herein are various open/closed stent designs and methods for creating the same that can be individually adopted depending on particular treatment objectives. Specifically, the stents of the present invention are manufactured to include different open/closed configurations along their length by varying the number of crossovers, connectors or weld points between sections of the stent. Open portions contain less crossovers, connectors or weld points and are more flexible than closed portions which contain more crossovers, connectors or weld points.

Some embodiments provide systems and methods for validating cached content based on changes in the content instead of an expiration interval. One method involves caching content and a first checksum in response to a first request for that content. The caching produces a cached instance of the content representative of a form of the content at the time of caching. The first checksum identifies the cached instance. In response to receiving a second request for the content, the method submits a request for a second checksum representing a current instance of the content and a request for the current instance. Upon receiving the second checksum, the method serves the cached instance of the content when the first checksum matches the second checksum and serves the current instance of the content upon completion of the transfer of the current instance when the first checksum does not match the second checksum.

A system for treating a diseased body conduit bifurcation that is readily deliverable into a region of a body conduit having typically asymmetric anatomy, such as a vessel bifurcation is provided. The system comprises a delivery device such as a catheter having a shaft with varying torsional properties along its length and a delivery apparatus mounted at its distal end. A distal end of the device can be inserted into the main branch and at least one side branch of a vessel bifurcation. The distal end includes at least two expansion members having expandable scaffolds or prostheses mounted thereon. One scaffold is configured such that one expansion member extends through the length of the scaffold while the other expansion member extends through the side-structure of the scaffold. A second scaffold is mounted on the expansion member extending through the side-structure of the first scaffold.

Methods and systems for triggerless screening of WMS messages for delivery with differential quality of service (QoS) are disclosed. Signaling messages are screened to determine whether they contain WMS content. In response to determining that a message contains WMS content, origination and/or destination party information is extracted from the WMS message to determine the QoS associated with the WMS message. The WMS message is then modified to include routing information for delivering the SMS messages to their intended destinations with different qualities of service.

The present invention relates to delivery of digital content of a content provider 110 to a user 160. The invention is based on the idea to utilize user presence information of a user in the delivery mechanism of digital content to the user. The operation of delivering digital content is separated in two co-operating services, a content service of a content provider 110 and a delivery service of a delivery provider 120. The content service utilizes the delivery service for accomplishing delivery of the digital content to a specific receiving user. Either the request to the delivery service to deliver the digital content, or the attempt by the delivery service to deliver the content, is made in dependence on user presence information indicating the availability of the user for receiving the digital content.
