Abstract: A system for removing an occlusion from a vessel. The system utilizes a shape memory polymer device for acting upon the occlusion. A transport vehicle moves a shape memory material through the vessel. The shape memory material is adapted to move from a first unexpanded coil shape to move through or around the occlusion, to a second expanded coil shape for acting upon the occlusion. A heat transfer mechanism is operatively connected to the shape memory material and is adapted to transfer heat to the shape memory material to move the shape memory material from the first shape to the second shape. The transport vehicle and the shape memory polymer material is withdrawn through the conduit carrying the occlusion matter. The system may include a second shape memory polymer device situated so that the occlusion material is gripped from both sides to facilitate removal.

Abstract: An apparatus for mounting within the trunk of an automobile to hold the spare tire of the automobile and allow the spare tire to be moved between a stored, out-of-the-way location and a location where it can be easily removed from and returned to the trunk. The apparatus includes a tongue member for engaging structure of the automobile when the spare tire is in the location where it can be easily removed from the trunk to support the spare tire and portions of the apparatus in that location and prevent twisting or turning of the spare tire and portions of the apparatus.
