Abstract: In general, techniques are described for managing content request referrals by keying content requests to a composite key data structure that maps end-user address prefixes and content identifiers to content delivery network servers of downstream CDNs. In one example, a CDN exchange includes a communication module to receive first network prefixes and first content identifiers from a first secondary content delivery network and to receive second network prefixes and second content identifiers from a second secondary content delivery network. A request router of the CDN exchange redirects the content request to the first secondary content delivery network or to the second secondary content delivery network according to a network address of the end user device and a content identifier for the content request.

Abstract: The present invention relates to an apparatus for securing a medical device. In particular, the present invention relates to apparatuses for securing medical devices in a desired manner, wherein the apparatuses having an elongated main body, an anchoring region, a medical device attachment region, and a connection region. Such apparatuses are useful for securing a particular medical device (e.g., a microwave energy delivery device) in a favorable position while conducting a medical procedure with such a medical device (e.g., ablation of peripheral lung tissue).

Abstract: Apparatus and method for separating individual human reproductive material from a fertilization dish and storing the material in a cryotank for future fertilization and implantation. The apparatus includes an elongate cryostraw having a first open end and second heat-sealable open end, a channel extending between said ends, and an internal, calibrated volume VC. A displacement bulb is connected to the first end of the cryostraw for admitting and emitting the material into said cryostraw. The bulb has a total volume VB1, an internal cavity with a compressible end volume VB2, a first seal with the first end of said cryostraw; and, means for limiting the intake volume displacement produced in said cryostraw to an amount less than VC no matter how far the bulb is squeezed. The bulb produces less than a unit volume of displacement in the cryostraw when the bulb is squeezed and its volume VB1 is reduced by a unit volume.
