HOUSING

摘要

A first housing (2) includes a first part (4) and a second part (6), both of which comprise PEEK-OPTIMA (Trade Mark) polymer. The two parts (4, 6) are arranged to cooperate so that they can be laser welded and define a hermetically sealed housing (2) which may house electronic (and/or other) components and maintain them in a dry, sealed environment. The housing and contained electronic components may define an implantable device, for example a heart pacemaker, for long term implantation in a human body.
