Abstract:
A radio access network includes a transport network layer; a radio network layer having a layer 2 network for communicating between entities within the radio network layer by exchanging datagrams having a predetermined format used only within the radio network layer. Accordingly, the present invention provides for a true decoupling at layer 2 between the radio network layer and the transport network layer.Addressing at layer 2 can enable both connectionless and connection oriented using an overlay connectivity model. Layer 2 in the radio network layer is implemented as an Ethernet network.
Abstract:
The present invention relates to injectable compositions comprising biocompatible, swellable, hydrophilic, non-toxic and substantially spherical microspheres useful for tissue bulking. The invention also relates to methods of tissue bulking, particularly for the treatment of Gastro-esophageal reflux disease, urinary incontinence, or urinary reflux disease, using the injectable compositions.
Abstract:
A method of deploying a stent-graft in a curved vessel includes deploying an expandable tip to center a proximal end of the catheter containing a stent-graft in the curved vessel. A sheath is retracted to expose the stent-graft and the stent-graft self-expands into the curved vessel. By centering the catheter containing the stent-graft prior to deployment with the expandable tip, the accuracy of stent graft placement within the curved vessel is improved.
Abstract:
The invention provides a flow transducer such as a flow cytometer for making simultaneous electronic and optical measurements on a particle flowing through a sensing zone.
Abstract:
The present invention provides a method of forming a drug eluting stent, the method comprising coupling a stent framework to a mandrel, inserting the mandrel with stent framework into an open die, the die including a forming surface including a plurality of raised indention forming portions; closing the die against the stent framework; pressing the raised indention portions into the stent framework to form indentions in the stent framework; and inserting at least one drug polymer into the indentions formed in the stent framework.

Abstract:
The present invention relates to elastic, hydrophilic and substantially spherical microspheres useful for dermal augmentation and tissue bulking. The invention provides injectable compositions comprising the microspheres and a biocompatible carrier for use in dermal augmentation. The present invention further provides methods of dermal augmentation and tissue bulking, particularly for the treatment of skin contour deficiencies, Gastro-esophageal reflux disease, urinary incontinence, and urinary reflux disease, using the injectable compositions.
Abstract:
An optical amplifier has at least first stage in the form of a distributed Raman amplifier and a second stage in the form of a discrete Raman amplifier. The discrete amplifier has an output for unused pump power, and the distributed Raman amplifier is pumped using the unused pump power from the second stage. This arrangement enables unused pump power to be used in a distributed Raman amplifier, in particular using the transmission fiber at the input to the second stage amplifier.
Abstract:
An animal restraint device is comprised of two identical mating collar elements, each element having a pair of outwardly extending legs and having at least one passage on one leg and at least one tab on an opposing leg such that the two elements may be connected by passing the respective tabs of each element through the respective passages of the other element, whereby when connected the elements define an aperture for receiving the animal's neck. A method comprises engaging a pair of collar members such that when connected, a neck of the animal to be restrained is positioned in an opening defined by recesses of the first and second collar members, the engaging step comprising engaging a locking member associated with each of the collar members with a passage associated with the other of the collar members.
