Devices and methods for treating defects in peripheral nerves are provided. The devices can include acellular arterial tissue matrices that facilitate regrowth of nerve tissue across a gap or defect in a peripheral nerve.
摘要:
A method of producing a modified acellular tissue matrix (mATM) from an acellular tissue matrix (ATM), where the mATM has a reduced stretchiness relative to the ATM, without substantially compromising its associated structural or functional integrity. The method includes providing an acellular tissue matrix (ATM) and exposing the ATM to elastase for a period of time.

Embodiments of the invention generally provide a method and apparatus for maintaining user sessions across user devices and portals. One embodiment of a method for maintaining a user session across a group including a plurality of user devices includes altering, at a first device in the group, a state of the user session, such that a new session state results and transferring the new session state from the first device to at least one of the other devices in the group.

A transparent routing device disposed within an access network configured in accordance with one or more lower-layer protocols is disclosed herein. The device includes a set of subscriber-side ports. Each of the subscriber-side ports is associated with a plurality of virtual subscriber-side interfaces disposed to effectively terminate a corresponding plurality of subscriber-side connections with subscriber host devices served by the access network. The device further includes at least one network-side port through which communication occurs with an external network in accordance with a higher-layer protocol. A routing table is configured to establish a correspondence between network addresses of the subscriber host devices and the plurality of virtual subscriber-side interfaces. During operation of the device, packets received through the at least one network-side port are forwarded to corresponding ones of the virtual subscriber-side interfaces based upon network addresses of the packets.
摘要:
The invention provides methods of storing acellular tissue matrices in which a substantial portion of water in the matrices is replaced with a water-replacing agent, e.g., glycerol. Also included in the invention are compositions made by these methods as well as methods of treatment using such compositions.

Systems, devices and methods for adaptive switching in multicast media streams are disclosed herein. In an embodiment, a method for adaptively transmitting content to one or more users based on currently available bandwidth via internet protocol (“IP”) multicast protocol, includes: receiving a first content stream having a plurality of data packets, the first content stream encoded at a first bit rate; receiving a second content stream having a plurality of data packets, the second content stream encoded at a second bit rate, wherein the first bit rate is different than the second bit rate and wherein the first and second content streams represent the same content; transmitting the first content stream to a user; determining that the user could receive the second content stream based on available bandwidth for transmitting data to the user; and transmitting the second content stream to the user.
摘要:
In one embodiment, a method for encoding content includes receiving source content and encoding the source content into a plurality of content streams. The encoding includes aligning the plurality of content streams at Group of Pictures (GOP) boundaries. The encoding further includes embedding, in each content stream, metadata identifying segmentation points within the content stream, where the segmentation points correspond to one or more of the GOP boundaries.
