Abstract: A guide device (1) for introducing at least a surgical instrument internally of an organic cavity (2), in particular a vascular cavity comprises a guide body or guide catheter (3) which is substantially hollow and flexible and exhibits an open directing end (8) which is transversal. The device comprises an elongate and flexible guide element (9), which is slidable internally of the guide body (3) to define an advancing guide for the guide body (3). The device (1) also includes means for stabilising (10) for easily piloting the directing end (8) with respect to the transversal cavity (2b) and for advancing the guide catheter. The means for stabilising are defined by a stabilising opening (11) and by an elongate and flexible stabilising element (12) which internally engages the guide body (3) and exits therefrom through the stabilising opening (11) along the cavity occupied by the guide body (3).

Abstract: A catheter, in particular for endovascular applications, including a long and flexible, hollow, tubular body having an insertion end and a connection end intended to remain outside the body. The catheter includes in the insertion end at least two elements which are expandable/contractible by means of external operations. Those 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 between the two expandable elements and, if necessary, in the intermediate arterial branch which, on account of the two elements upstream and downstream, will have a zero flow.

Abstract: A prosthesis for large blood vessels includes a main conduit. At least one tract of the main conduit is subdivided into a plurality of smaller conduits located parallel to one another.

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.
