Abstract: The present invention relates to woven tubular nanotextiles, fabrication thereof using a weaving apparatus, and use thereof in vascular graft applications. The woven nanotextile conduit is 0.1 to 50 mm in diameter and includes a multitude of hierarchically arranged nanofibers. They are made from low strength bundled nanoyarns containing thousands of nanofibers with improved mechanical strength. The weaving apparatus interweaves the warp and weft yarns in longitudinal and transverse directions, resulting in a flexible and strong woven product. The physical and biological properties of the woven nanotextile were significantly enhanced when compared to non-woven nanofibrous form and conventional medical textiles. The nanotextile displayed superhydrophilic behavior in an otherwise hydrophobic material and when implanted as a vascular graft was robust, suturable, kink-proof and non-thrombogenic, with complete endothelialization of the graft luminal area.

Abstract: The invention discloses a saturable drug delivery implant made of a woven fabric material with variable packing density, dimension and weight. The woven fabric material includes electrospun continuous yarn with individual micro- or nano-fiber yarn made from a single polymer. The yarn is loaded with at least one therapeutic agent to provide controlled and sustained release when the device is sutured to a wall of the peritoneal cavity of a subject. The woven fabric is flexible, biodegradable and configured to be sutured to the wall of a body cavity to provide a sustained and controlled release of therapeutic agent in a subject. In some aspects, a peritoneal implant is sutured to the peritoneal wall cavity for continuous and sustained intraperitoneal release of a therapeutic agent.

Abstract: Electrospinning apparatus and method for producing multi-dimensional structures such as one-dimensional continuous yarns, two-dimensional mats and three-dimensional cotton-like fluffy scaffolds is disclosed. Further, electrospinning apparatus and method with single collector geometry for producing multi-dimensional structures and core-sheath yarns are disclosed.

Abstract: Aporous composite fibrous scaffold for repair or regeneration of bone is disclosed. The scaffold comprises a first biopolymer forming a porous matrix and a second biopolymer forming fiber reinforcement. The biocompatible scaffold is configured to maintain balance between porosity and mechanical strength which could aid cellular infiltration and bone tissue regeneration. A method of preparing the porous composite scaffold is also disclosed.

Abstract: A method and system for multicasting data in a communication network (100) to a specific group of user equipments (UEs) (120) that includes a source UE (102). The method provides for communicating (302) at least one FlowID to the specific group (120), the communicating including informing the specific group (120) of a broadcast server's IP address and port number to allow the UEs to set up resources in the network (100) for reception of wireless multicast data. The method also includes allowing (303) the source UE (102) to have a floor control for the specific group (120) that are uniquely identified in the network (100), the allowing being provided by a push server (112). Next, the method provides for receiving the data (304) at the broadcast server (114), from the source UE (102), and then multi-casting the data in non-duplicated packets to the specific group (120).
