    摘要: A method of facilitating access to a neonate through a caesarean incision in the woman's abdomen by opening the incision, includes providing a supporting ring dimensioned to allow delivery of a neonate through the ring and comprising a non-adjustable pelvic-region retractor and handle fixed to the supporting ring and articulating the supporting ring to insert the non-adjustable pelvic-region retractor into the incision to cover and hold back the woman's bladder with the supporting ring disposed over the woman's abdomen. A first adjustable saddle-shaped retractor is then inserted into the incision to cup a first section of abdominal tissue on an abdominal side of the incision, before attaching the first adjustable saddle-shaped retractor to the supporting ring while it is cupping the first section of abdominal tissue at a first position spaced apart from the non-adjustable pelvic-region retractor to anchor the supporting ring to the woman and partially open the incision.

    摘要: An implantable medical device having a soft tissue interfacing surface comprises at least one soft actuatable capsule having a soft tissue interfacing deflectable membrane configured for cyclical deflection upon actuation of the capsule to modulate the biomechanics of the soft tissue interface during use. The actuatable capsule may comprise an actuation chamber containing a first fluid, a therapeutic chamber containing a second fluid, a deflectable membrane separating the actuation chamber and therapeutic chamber, and an actuation conduit in fluidic communication with the actuation chamber for pneumatic actuation of the actuation chamber. The therapeutic chamber comprises the soft tissue interfacing deflectable membrane which is configured to cyclically deflect during actuation of the capsule and modulate the biomechanics of the soft tissue interface by altering one or more of strain, fluid flow and cellular activity in peri-implant tissue at the soft tissue interface. Methods of reducing fibrotic encapsulation of an implantable medical device are also described.

    摘要: A method of producing a multi-layered functionalised graphene oxide paper, comprises the steps of providing an aqueous suspension of oxidised graphene oxide flakes, size reducing the oxidised graphene oxide flakes in the suspension to provide an aqueous suspension of particulate oxidised graphene oxide having an average particle size of less than 1 μm and drying the aqueous suspension in a vessel to provide a multi-layered graphene oxide material. The multi-layered graphene oxide material is annealed to provide a multi-layered reduced graphene oxide material, before surface grafting functional groups to the surface of the multi-layered reduced graphene oxide material by reacting the material with a functional group precursor in the presence of plasma. The use of a graphene oxide material to treat bone defects, and as an energy storage device, is also described.
