摘要： An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may, in different embodiments, directly cool tissue contacting the balloon, or may cool a separate internal chamber. In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter. Plural balloons may be provided, wherein a secondary outer balloon surrounds a primary inner balloon, the primary balloon being filled with coolant and acting as the cooling chamber, the secondary balloon being coupled to a vacuum return lumen to serve as a robust leak containment device and thermal insulator around the cooling chamber. Various configurations, such as surface modification of the balloon interface, or placement of particles, coatings, or expandable meshes or coils in the balloon interface, may be employed to achieve this function.

摘要： A data transmission system wherein data to be transmitted is supplied to an encoding device (5) which comprises a data analysis circuit (35) for producing a parity code and an output circuit (32) for assigning the parity code to the input data so as to convert it into protected data for transmission. The data analysis circuit includes: (i) a serial-to-parallel converter (30) for converting the input data into "n" parallel data streams, the bits in each stream being at instants which are multiples of n.times.T, where T is the bit period of the input data; (ii) "n" cascade combinations of delay elements, each cascade delaying one of the "n" parallel-converted data streams by time periods which are multiples of n.times.T, each cascade having tapping points following certain ones of the delay elements therein; and (iii) combining circuits (GR1, GR2, OE) having inputs connected to tapping points of each of the cascade combinations and which derive the parity code.
