Abstract: A system and method for providing internet access using mobile devices is disclosed. A gateway/router device of a local environment selects at least one mobile device located within the local environment, the selecting being based on the at least one mobile device having a wireless connection to the internet. The gateway/router device established a local connection with the selected at least one mobile device, the local connection for communicating data signals between the at least one mobile device and the gateway/router device on a first hop, and for communicating the data signals between the selected at least one mobile device and the internet on a second hop via the wireless connection between the at least one mobile device and the internet. The gateway/router device communicates the data signals between at least one other internet-enabled device within the local environment.

Abstract: A medical condition associated with a cardiac structure is treated by injecting an injectable polymer agent into the cardiac structure such that a therapeutic mechanical scaffolding is formed within the cardiac structure itself. In particular, the injectable scaffolding agent is a fibrin glue agent and is injected into regions of damaged myocardium such as ischemic tissue or infarct. LV wall dysfunction may also be treated by injecting the scaffolding agent into the LV wall. Cell therapy may be combined with the injection of fibrin glue or other injectable polymer scaffold agent. The polymeric forms of the agent may be injectable as precursor materials that polymerize as a scaffold in-situ within the cardiac structure. In other modes, polymer agents are injected in order to provide therapeutic angiogenesis, or to induce deposition of cells within the injected area, such as by providing the polymer with fragment E or RDG binding sites, respectively.

Abstract: A system forms a cardiac conduction block at a location in a heart of a patient without substantially ablating cardiac tissue. The system includes a delivery system coupled to a source of material that is substantially non-ablative with respect to cardiac tissue. The delivery system delivers the material to the location, and the material at the location forms a conduction block without ablating the cardiac cells there. The material may include living cells, such as for example skeletal myocytes, and/or may include a non-living matter such as biopolymers such as a fibrin glue agent. An expandable member with needle assembly is used to deliver the material so as to form a non-ablative circumferential conduction block at a location where a pulmonary vein extends from an atrium.
