Abstract: An inflatable medical balloon is formed by fabricating a tubular preform having a tapered region at the end of the portion where the main body of the balloon will form to enable the corresponding transition section of the blown balloon to have a separately controllable thickness profile. The preferred method includes providing a tube of a selected resin of wall thickness and diameter suitable for being formed into a balloon, and selectively heating to drawing temperature a defined region of the tube at one or both ends of the portion of the tube from which the balloon is to be formed. Tension is applied in opposite directions to respective ends of the heated region to draw the region to a smaller diameter, thereby providing a preform having, at the end of the portion of the tube, a tapered, relatively small diameter region of material that has substantially no crystallization or molecular orientation. In preferred embodiments a tapered region is provided at both ends of the portion in which the main body of the balloon is to be formed. Thereafter the tubular preform is heated to blowing temperature and, while heated, a balloon is formed by drawing and blowing the preform including the tapered regions. The balloon is mounted to form a balloon catheter device. A dilatation balloon catheter, is also described having wall thickness in the transition region less than 0.001 inch.

Abstract: This invention relates to a telecommunication system including a conference information system including a number of participants each equipped with a separate node (2, 4, 8), which conference nodes may be interconnected via a switching network (1) such as a public switched telephone network, and where each participant node (2, 4 , 8) is including means for receiving a sum conference information signal from the other participating nodes, means for adding the signal generated in each conference node to the sum signal, and means for controlling the conferencing functions. According to this invention all of the nodes (2, 4, 8) in the conference connection are interconnected in a complete conference ring (11) by means of one single connection (12) in which the information signals are transmitted from node to node in one single direction (arrow 12). Some of the advantages of this system are   a conference may be established even if the possibly centrally arranged exchange is not provided with a conference facility. The conference facility is introduced by equipment distributed in each node terminal. The line requirement is reduced to the half, but still the same traffic capacity may be handled by the system. all the nodes now get identical status in the ring, and therefore all of the nodes may be designed as quite identical circuits.   <IMAGE>
