Abstract: ABSTRACT     A blood clot filter which is particularly suited for filtering emboli from blood circulating  through the inferior vena cava.  The filter is comprised of a number of strands of shape memory wire which are interconnected and wadded together to form a curly wire mesh.  The wire strands may be substantially straightened in order to permit insertion of the filter within the lumen of an angiography catheter.  The filter includes a number of projections which serve as an anchoring means for anchoring the filter at a suitable body location within the inferior vena cava.  One of the strands of wire includes a zig-zag which permits the attachment of the filter to the stretched distal end of a helically formed wire guide, thereby permitting the filter to be urged longitudinally through the lumen of the catheter for positioning within the inferior vena cava.  In order to implant the filter, a percutaneous catheterization is made using a femoral approach.  Once inside the inferior vena cava, the filter is pushed out of the catheter using the wire guide.  The filter automatically expands to fill the passageway of the inferior vena cava without causing substantial occlusion thereof.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a system for automatically succes-sively inserting a plurality of U-shaped heat transfer tubes into holes of support members of an equipment such as a heat exchanger.  The system has fixing means for removably fixing the support members such that the corres-ponding holes of the support members are axially aligned; gripping means adapted to pick up one of the heat transfer tubes and movable to bring the heat transfer tube toward the holes of supporting members; a positioning means disposed between the gripping means and the fixing means and adapted to hold the gripped heat transfer tube horizontally and to make the same align with the holes in the support members; and control means operatively con-nected to the gripping means and the positioning means so as to sequentially control the operation of both means in a predetermined sequence.  The system operates as follows under the control of the control means.  The gripping means grips the heat transfer tube and raises the same.  The gripping means is then moved toward the support members while the positioning means supports the heat transfer tube.          As the heat transfer tube is inserted deeper into the support members, the support of the tube by the positioning means is released.  The gripping of the tube by the gripping means is released and the gripping means is then returned to the position for picking up the next tube, after the comple-tion of the insertion of the heat transfer tube.
