Patent CA-2037056-A1 (CA)
Title: Tissue sampler
Inventor: HESKE NORBERT F
IPC: A61B10/00
Filed: 1990-07-20
Abstract: A b s t r a c t  o f  t h e  I n v e n t i o n What is described here is a device for taking tissue samples by means of a biopsy cannula comprising a needle element with a cavity in its distal terminal zone and an exterior tube surround the needle element, which cannula is inserted into the tissue to be sampled by means of an inserting unit.            The invention is characterized by the aspects that the inserting unit causes the needle element and the exterior tube to move jointly into a position inside the tissue in which the exterior tube is pushed over the cavity, that the inserting unit retracts the exterior tube behind the cavity in the needle element after termination of the in-serting operation, and subsequently pushes the exterior tube again over the needle element so as to cover the cavity.

Title: Water jet atherectomy device
Inventor: DRASLER WILLIAM J
IPC: A61M1/00
Filed: 1991-07-31
Abstract: WATER JET ATHERECTOMY DEVICE                 ABSTRACT OF THE DISCLOSURE    A technique for treatment of plaque deposits on the arterial wall of a patient.  The technique employs a high pressure jet of sterile saline solution directed at  the  plaque  deposit.    The  high  pressure  jet  is located at the distal and of a guide wire or catheter which is advanced through the vascular system to the site of the plaque deposit.   Optional removal of the debris is via an evacuation lumen within the catheter.    This  particular  technique directs  the  high pressure jet of fluid distal to the distal tip of the guide wire or catheter.   This permits treatment of arteries,  which  are  totally  occluded,  because  the device need not transit the lesion to be effective.   Some applications will use the high pressure jet of fluid to open a sufficient passage within the occlusion to permit further dilatation using a balloon integral to or passed over the device.    An ultrasonic transducer array located adjacent the high pressure jet permits the attending physician to monitor the procedure.   This may be particularly important  for  those  embodiments  for which  the high pressure jet of fluid may be inadvertently directed toward the vessel wall at short range.  The ultrasound device ensures that the jet of fluid is directed at plaque, rather than the native vessel.

Abstract: SAND CONSOLIDATION METHODS         (D#91,007-F) ABSTRACT OF THE DISCLOSURE         Disclosed are methods for consolidating unconsolidated mineral particles such as sand in a subterranean petroleum formation penetrated by a well.         A fluid containing a polymerizable resin such as furfuryl alcohol, a polar organic diluent such as butyl aldehyde and an oil soluble acid catalyst such as toluenesulfonic acid capable of causing polymerization of the resin at formation temperatures is prepared.          The acid should have a pK in the range of 0.50 to 1.30 and the acid concentration is carefully selected to cause the polymerization reaction to be essentially complete in from 0.75 to 4.0 hours and preferably 1.0 - 2.0 hours at the formation temperature.  Usually the selected acid concentration will be in the range of from 0.2 to 5.0 percent.  This fluid is injected into the formation to saturate at least a portion of the formation adjacent to the well.   An aqueous fluid comprising water which is from 70 to 100 % saturated inorganic salts including sodium chloride is injected into the same portion of the formation contacted by the resin containing fluid.          The injected fluids are allowed to remain in the formations for at least four hours to accomplish at least partial polymerization of the resin, forming a permeable consolidated mass around the wellbore.

The vias are spaced closely enough to prevent the escape or entry of RF waves at the frequencies of interest.  The RF shield is advantageously fabricated using metallizations and vias that are optically patterned by the same process steps used to effect hybrid interconnection of the chips.
