Abstract: The invention relates to a catheter, in particular for endovascular applications, comprising a long and flexible, hollow, tubular body (1) having an insertion end (4) and a connection end (3) intended to remain outside the body. According to the invention, the catheter comprises in the insertion end (4) at least two elements (9, 12) which are expandable/contractible by means of external operation. Said elements are located at a distance from each other, one upstream and the other downstream of a given section of a vessel. With the catheter it is possible to operate in the section comprised between the two expandable elements (9, 12) and, if necessary, in the intermediate arterial branch which, on account of the two elements (9, 12) upstream and downstream, will have a zero flow.

Title: Wind generator machine for producing high-power electrical energy
Inventor: BONARDI DANTE
IPC: F03D/
Filed: 1994-02-15
Granted: 1997-10-28
Abstract: The present patent for an industrial invention relates to a wind generator machine which exploits wind energy on a large scale, converting it to electrical energy. At the present time there are only wind generators with horizontal axes and a plurality of blades and combined wind generators with vertical axes, all being made with a central drive shaft or rotor and developing a limited power in terms of kilowatts. The invention differs from all existing wind generators constructed up to the present time in that, since it has no central shaft, it can be made with a large diameter and a large height, and can be of circular, elliptical or oval shape, generating electrical energy at very high power in windy areas. The wind generator machines are constructed on large circular structures with frames in the form of fixed towers anchored to the ground; the size of these towers can be very great and they must be constructed to match the mean wind force which has presumably been calculated for a specific locality. <IMAGE>
