Abstract: An implantable medical lead for implantation in a patient which has at least one electrical conductor connected to at least one electrode and/or sensor of said lead. The at least one conductor is arranged within a continuous sheet of a polymer material. A distal portion of the lead is adapted to be located in or at a heart of said patient and a proximal portion of said lead is connectable to an implantable medical device and arranged such that, when connected to the device, at least a part of the proximal portion of the sheet is placed in dose proximity to said medical device.

Abstract: An implantable device comprises a polymer structure having an outer surface facing a surrounding tissue when the implantable device is implanted in a subject body. At least a portion of the surface of the structure has a semi-random pattern of extending micropillars. The semi-random pattern of micropillars on the surface contributes to advantageous surface characteristics of the implantable device in terms of reducing adhesion viable cells to the implantable device as compared to regular patterns of micropillars.

Abstract: In an elastomeric tube and a method for making such a tube, two medical-grade silicone rubber compositions are coaxially coextruded to form a tube. The compositions respectively differ in at least one physical property and respectively have similar curing conditions. The two compositions are blended at an interface formed between the two compositions during the coextruding, so that between 1-99% of the tube forms a blended gradient. The coextruded tube is then cured.
