  • Publication number: 20200384153
    Abstract: A haemostat agent in the form of a multi-layer patch comprising at least first and second layers, wherein said first layer comprises a composition comprising fibrous ?-chitin (which may be sourced from a marine source such as squid pens) and one or more biocompatible polymer (for example, a polyethylene glycol (PEG) polymer or sodium polyphosphate (PolyP)), and said second layer comprises a film layer comprising fibrous ?-chitin. In one particular application, the haemostat agent is used for treating carotid artery injury associated with endonasal surgery.

  • Publication number: 20200384159
    Abstract: Methods are disclosed which combine electrospinning and a sacrificial template, such as with additive manufacturing (AM), to produce fibrous microvascular scaffolds which are biodegradable, porous, and easily handled. In one example, a process for fabricating a fibrous network construct is disclosed. The method includes electrospinning a first layer of fibrous material; printing a micropatterned sacrificial template; transferring the micropatterned sacrificial template onto the electrospun fibers; electrospinning a second layer of fibrous biomaterial onto the micropatterned sacrificial template thereby encapsulating the template and generating a construct with two layers; and removing the sacrificial template, producing a fibrous construct with channels or microstructures formed therein. Also disclosed are fibrous constructs and scaffolds produced by the provided methods.
