Patent CA-2182478-A1 (CA)
Title: Percutaneous drug dosing closure system
Inventor: NASH JOHN E
IPC: A61B17/00
Filed: 1995-01-31
Abstract: A resorbable dispensing device (20, 20') for location in a percutaneous incision or puncture (22, 24) extending to an internally located penetratable or-ganic structure within the body of a liv-ing being to provide at least a first bio-logically active material (72) for uptake by the body. The percutaneous incision or puncture includes an opening (22) in the tissue forming penetratable struc-ture and a communicating tract (24) ex-tending from the opening. The dispens-ing device can be used as a hemostatic closure and basically comprises anchor-ing means (32, 32', 32'', 32'''), sealing means (30, 30'), and positioning means (34), e.g., a filament. The anchoring means (32, 32', 32'', 32''') is introduced through the opening (22) onto one side of the penetratable structure to engage a portion of the tissue adjacent the open-ing to hold the anchoring means in place. The sealing means (30, 30') is arranged to be introduced into the tract (24) adja-cent the anchoring means and to be po-sitioned by the positioning means (34) on the other side of the tissue from the anchoring means to hold the entire device (20, 20') in position within the percutaneous incision or puncture (22, 24). The first biologically active material (72) is selected to have little or no significant clotting or anti-clotting effect on the blood of the being but has at least one significant physiological effect, e.g., therapeutic, diagnostic, or prophylactic, and is carried by at least one of the anchoring means (32, 32', 32'', 32''') and the sealing means (30, 30'). When used as a hemostatic closure the sealing means may carry a conventional blood clotting agent, e.g., tissue thromboplastin. If the anchoring means is located in a blood vessel it may carry a conventional non-thrombogenic material.

Abstract: A  balloon  dilation  catheter  includes  a  distal monorail section, to which a balloon is secured, and a catheter body tube including a monorail section.  A guide tube extends through the balloon and has a proximal end sealed to a guide wire port in the body tube.  A guide wire extends along the body tube and through the guide tube.    To  stiffen  the  body  tube  while  maintaining maximized fluid flow area,  a stainless steel hypotube extends through the proximal body tube,  has a distal opening positioned adjacent the guide wire port and a solid reinforcing tapered distal end section that extends across the guide port.   The hypotube can be fixed or removable.    Alternatively,  the  hypotube  divides  the interior  of  the proximal  body tube  section  into two separate flow passages to enable positive purging.

Title: Method and apparatus for automated biopsy and collection of soft tissue
Inventor: FOGARTY THOMAS J
IPC: A61B17/22
Filed: 1995-03-20
Abstract: A method and device for the automated biopsy and collection of soft tissue having a piercing needle with a receiving port to trap tissue prior to cutting. A motor drive directs and positions the tissue receiving port at a lesion site in arbitrary positions about and along the longitudinal axis of the device. A cutter advances into the receiving chamber and severs tissue which has prolapsed into the receiving port. The severed tissue is then removed from the receiving port without removing the piercing needle receiving port from the lesion site, thus allowing for the accurate, rapid removal of an arbitrary number of core samples with only one insertion. A tissue sample cassette provides storage for the samples as well as means for coding and decoding the location from which the samples were obtained. Together, these features allow for more accurate and complete sampling of large lesions, for the complete removal of small lesions or removal of other tissue for a variety of reasons.

Inventor: HUANG JAY JIE
IPC: H04B1/38
Filed: 1996-10-16
Abstract: A method for reducing interference to electronic devices caused by discontinuous transmission from a radio transmitter is disclosed and a transmitter which carries out such a method.  In order to reduce such interference the transmitter continues to emit radiation at the same power level as when transmitting information, when no information needs to be-transmitted.  When no information needs to be transmitted, the transmitter switches frequencies to another carrier frequency from the communication frequency so that other transmitters can transmit on the communication frequency when the transmitter is not transmitting information.

Title: Method and apparatus for determining the thickness of a well bore casing
Inventor: HERVE PHILLIPPE G
IPC: E21B47/00
Filed: 1995-09-22
Abstract: An improved technique for determining the thickness of a member, especially pipe such as fluid-filled casing in an earth borehole, includes the following steps: directing a pulse of ultrasonic energy toward the inner surface of the pipe, and receiving and storing, as a function of time, signals representative of ultrasonic energy reflected from the inner surface of the pipe;  determining, from the stored signals, the arrival time of the initial echo from the inner surface;  determining, from the stored signals, thearrival time and the amplitude of a first candidate initial echo from the outer surface of the pipe; performing a reverse search on the stored signals to determine, from stored signals at times earlier than the arrival time of the first candidate, the arrival time and the amplitude of a second candidate initial echo from the outer surface; comparing amplitudes of the first and second candidates, and selecting, based on the comparison, one of the first and second candidates as the actual outer surface echo; and determining the thickness of the pipe from the arrival time of the actual outer surface echo and the arrival time of the inner surface echo. Using this technique, the earlier arriving candidate can be properly identified as the actual outer surface echo, even when the later arriving candidate has a greater amplitude.

Inventor: JIANG JIAN ER
IPC: D21C3/02
Filed: 1997-05-20
Abstract: The production of chemical (e.g., kraft) cellulose pulp much more suited to totally chlorine free or elemental chlorine free bleaching is produced by reducing the bleaching chemical consumability of the produced pulp. The effective alkalinity of the pulp during at least the majority of the cooking stage is maintained at about 15 g/1 or above (e.g., about 18-25 g/1), expressed as sodium hydroxide, so as to reduce the charged acid groups (including hexeneuronic acids) by at least 30% (e.g., at least about 50%) compared with pulp cooked at conventional alkalinity. Instead -- or in addition to -- the cellulosic material which produces the pulp may be heated to a temperature (at least about 100°C, preferably at least about 130°C) to release significant quantities of the transition metals within it, and preferably while it has this elevated temperature and a dissolved organic solids concentration of about 120 g/1 or less, a chelating agent (such as EDTA) is added to combine with a significant quantity of the released transition metals to produce complexes. At least a majority of the complexes are preferably removed (e.g., using an extraction screen in a digester) before the pulp is bleached.
