Inventor: SIEROCUK THOMAS J
IPC: A61M25/10
Filed: 1996-03-21
Abstract: A surgical instrument having an elongated shaft to which is attached an inflatable balloon, commonly referred to a "balloon dissector", for dissecting a desired layer of internal bodily tissue from remaining tissue layers to create an operative space is disclosed. Alternatively, an instrument without a balloon can be used to perform a manual dissection. In one embodiment, the instrument has a tissue-contacting element in communication with the shaft distal end, and at least a portion of the tissue-contacting element is transparent. The instrument is adapted to receive an endoscope through its shaft and extend to adjacent the tissue-contacting element. The endoscope is supported and positioned in an extension assembly. The instrument provides for visualization using the endoscope as the instrument is advanced through tissue, but prevents direct contact between the tip of the endoscope containing the lens and the tissue. The extension assembly also enables the endoscope to be adequately positioned and supported beyond the shaft distal end. When the instrument incorporates the balloon, the endoscope can extend into the lumen of the inflated balloon. In this way, improved visualization during use can be obtained.

Title: Ultrasonic therapy and assessment apparatus and method
Inventor: KAUFMAN JONATHAN J
IPC: G01N29/34
Filed: 1993-11-08
Abstract: Non-invasive therapeutic treatment and/or quan-titative evaluation of musculoskeletal tissue are per-formed in vivo by subjecting musculoskeltal tissue (11) to an ultrasonic acoustic signal pulse extraction, involving a composite sine wave signal consisting of plural discrete frequencies that are spaced in the ul-trasonic region to approximately 2 MHZ, and repeated substantially  in the range of 1 Hz to 1000 Hz. In a quantitative evaluation the signal is supplied to one of two transducers (12, 13) on opposite sides of the tissue, and the signal received by the other transducer is processed (14): (a) to obtain an averaged per-pulse signal and (b) to produce a Fourier transform of the averaged per-pulse tissue transmittal signal. In a sep-arate operation, the same transducers are subjected to the same excitation, reception and processing, using a medium of known acoustic properties and path length to produce a reference Fourier transform. In a ther-apeutic treatment, the transducer (12) excited by the composite sine wave signal is applied for a time pe-riod and magnitude.

Title: Method for querying incrementally maintained transactional databases
Inventor: JAGADISH HOSAGRAHAR VISVESVARA
IPC: G06F12/00
Filed: 1996-05-09
Abstract: The chronicle data model of the present invention permits the capture, within the data model, of many computations common to transactional recording systems. An important aspect of the chronicle data model is incremental maintenance of materialized view in time independent of the size of the recorded stream. The chronicle data model differs from the relational model in that it encapsulates within itself (1) support for aggregate, or summary, queries over sequences that may not be stored in their entirety, through the use of materialized (or persistent) views; and, (2) automatic incremental maintenance of persistent views as records are inserted into the sequence.     A chronicle data model can be implemented on top of a relational system. An aspect of this invention is to reduce the complexity of the application domains that need a chronicle system by encapsulating this model within the database. Within the chronicle data model of the present invention is disclosed: the type of summary queries that can be answered by using persistent views is determined, the complexity of incrementally maintaining the persistent views and development of a language ensuring low maintenance complexity independent of the sequence sizes.
