Housing for a functional element
First Claim
1. A housing for a functional element, in particular for use in the medical field in naturally occurring vessels in the body, the housing wall of which has a slack, flexible, tensionable membrane with a plurality of formed parts secured thereon which support the membrane in the tensioned state thereof by forming one or more groups of formed parts wherein the formed parts of each group support one another in the tensioned state of the membrane, said formed parts of said groups positioned in a gap free relationship with respect to one another in said tensioned state, and a functional element comprising a fluid pump which produces an excess pressure in the housing which leads to tensioning of the membrane.

Abstract
The invention relates to a housing (8) for a functional element (5), in particular for use in the medical field in naturally occurring vessels in the body, the housing wall of which has a slack, flexible, tensionable membrane (8a) with a plurality of formed parts (8b, 8c) secured thereon which support the membrane in the tensioned state thereof. Hence the housing can be expanded and compressed easily, the membrane being supported effectively in the expanded state by formed parts.
