Abstract: A method of making a stent delivery system is provided in which a delivery catheter has a balloon that extends non-uniformly into interstices of a stent. In accordance with the method a balloon/stent/crimping tube assembly is placed in a crimping tool, the balloon is inflated, and the crimping tool is actuated to compress the stent on the outside of the balloon without application of heat or chemicals, thereby causing creases of the balloon to extend non-uniformly into the interstices of the stent. Optionally, pillows may be formed in the balloon to prevent longitudinal movement of the stent with respect to the balloon during intravascular delivery. One or more secondary crimpings also may be performed to achieve a smoother delivery profile.

Abstract: The space heating system has a stove (1, 2) with a sealed combustion chamber (3); air is heated in the stove in a heat exchanger (12) therein, and heated air is conducted through hollow blocks (80) of chamotte arranged, for example, as heating panels, heated walls, benches, floors or the like. The hollow blocks are formed, internally, with projections or obstructions (83) to increase heat transfer, and may be faced at the outside with decorative tiles. To seal the combustion chamber, a vertically movable panel, typically of fire-resistant glass, is slidably located in front of a fuel inlet opening (7). In operation, the panel is sealed, so that the combustion chamber (3) will receive air only under controlled conditions, in two air paths; a primary air path supplies air to a narrow space (22) below a fuel support grate (25), after being preheated by passing around an ash receiver (18); and a secondary air flow, passed through ducts (30) within the combustion chamber, and ejecting air towards the panel.
