Abstract: A method for reducing the number of error events in a transmitted data stream (34) comprises the steps of (i) generating at least a first most probable sequence (16(1)) and a second most probable sequence (16(2)) with a detection algorithm (12); (ii) determining if a first correctable error occurred in the first most probable sequence (16(1)) with an EDC decoder (14); and (iii) determining if a second correctable error occurred in the second most probable sequence (16(2)) with the EDC decoder (14). Additionally, the steps of determining if a first correctable error occurred and determining if a second correctable error occurred can be performed substantially simultaneously. The method can further comprise computing a plurality of path metrics (42) for the transmitted data stream (34); and selecting a first q smallest path metrics out of the first and second most probable sequences (16(1)), (16(2)) with a Q value selector (44).

Abstract: A method is disclosed for producing an inflatable balloon catheter having an inflatable catheter tip attached to a double lumen catheter shaft to form a smooth, continuous outer surface at the outer juncture of the tip and shaft. The tip is molded and comprises a hollow, thin-walled, cylindrical balloon section that has at least one open end. Mating die members are provided to define a cylindrical mold cavity having inside diameter substantially equal to the inside diameter of the balloon section. The catheter shaft is extruded to have initial outside diameter substantially equal to the outside diameter of the balloon section and, while in a partially cured state, a leading portion of the extruded shaft is stretched to locally reduce its outside diameter. The stretched portion is clamped between the die members in the mold cavity to form a shoulder at a transition between this leading portion and the remainder of the shaft. The entire shaft is then cured.
