摘要: An upright column is packed with particles of a first material so the particles touch one another and a network of voids is defined between the particles. The network will be substantially continuous. A second material is then introduced into the column so the second material penetrates the network and fills the voids. The mixture of first and second materials is then consolidated using heat to melt the first or second material, while the other one of the first or second material remains in a solid state and acts as a space holder. Thereafter, the material which acts as the space holder may be removed thereby to leave a substantially continuous porous network defined by the material which was melted. It is found that, by use of the method, a substantially continuous network of the material which is melted can be formed and that the other material can readily be removed and/or is more easily removed compared to if a mixture of first and second materials was formed prior to packing in a column or mold.

摘要: Pellets or granules comprise polymeric material, for example polyetheretherketone and a fugitive material, for example sodium chloride. The granules may be used in injection moulding to produce shapes for use in medical implants and may conveniently be used to form parts which are partially porous, or to prepare porous films.

摘要: An assembly comprises first and second parts which bear against one another, wherein said first part comprises a polyetherketoneketone and said second part comprises a polyetherketoneketone. The parts bear against one another such that one or both of the parts may have a tendency to wear and/or produce wear debris by virtue of contact between the parts. The materials used, however, minimise wear and the production of such wear debris.

摘要: An enclosure of an active implantable device comprises a composite material which comprises a first layer of a polyetheretherketone film, a second layer of polyetheretherketone film (8) and, sandwiched between, a third layer comprising titanium. The arrangement may be provided in various embodiments such as comprising housing halves (70,72) and a lid (74), each being made of the three layers described. In one embodiment, a communications window may be provided which has a thinner layer of titanium, to facilitate communications between the outside and electrical components positioned within the enclosure.

摘要: Topographical features, such as projections or recesses, having a maximum dimension which is less than 3 μm, with the features being separated by a distance which is less than 10 μm are transferred to polyetheretherketone, on an industrial scale, by injection moulding relatively low viscosity PEEK, using a mould in which is arranged a master structure which carries the desired topography. The topographical features increase the water contact angle of a surface which includes them and such a modified surface has been shown to influence cell attachment and differentiation. Parts which incorporate the topographical features may be used in medical devices such as implantable medical devices for cardiology or for neuromodulation.
