<p>An integral fluid filter and capillary restrictor unit (40), or alternatively an integral fluid filter and multiple orifice restrictor unit, is resiliently positioned in a manifold body (22) which is edge mounted to a flat cylindrical assembly which contains the medication reservoir (18) and pressure stabilizing chamber (20) to provide a completely self- contained implantable unit which is thin, small and lightweight and yet needs to be refilled only as often as the much larger stainless steel capillary tube devices with bellows type reservoirs now on the market.</p> |
