Patent CA-2222142-A1 (CA)
Inventor: MELSKY GERALD S
IPC: A61M1/02
Filed: 1996-03-21
Abstract: A vascular access system has an implantable head which includes a pair of similar access ports, each port having an internal chamber with an open mouth, an outlet cannula extending from the port and being in fluid communication with the corresponding chamber and a domed septum closing the mouth of the corresponding chamber. A flexible dual-lumen catheter is connected to the head. The catheter has a pair of unitary closely spaced-apart parallel lumens which are separable so that the catheter proximal end can be connected to the head's outlet cannulas, with the outlet cannula of one port being received in one of the catheter lumens and the outlet cannula of the other port being received in the other catheter lumen. Locking sleeves are provided on the head for locking the outlet cannulas in their respective catheter lumens and a special access needle is provided for accessing the head to avoid coring of the head's septa.

Abstract: A polyaxial colletted locking mechanism for use with orthopedic apparatus includes a screw (170), hook (190), or other orthopedic implant element having a curvate head (172, 192), and a coupling element (100a). The coupling element (100a) has a tapered and colletted portion (102a) having an interior chamber (116a) in which the curvate head (172, 192) is initially polyaxially disposed. A locking collar (160) is disposed around the tapered and colletted portion (102a) such that translation thereof in the direction of the expanding taper causes the interior volume (116a) to contract onto the curvate head (172, 192) and lock it therein. The coupling element generally also includes a rod receiving recess (122a) in either the side or top thereof for receiving a rod of the total implant apparatus. The locking collar (160) may be caused to translate into its locking position by a mutual threading on the tapered portion and the collar, or by pressure applied to it by a separate element (150) which locks the rod in the channel.

Abstract: A two colored baseball or softball for practice.  One half of the outer surface is a dark color and one half is light to make the ball more difficult to see than a standard ball. When  used  for  practice,  the  ball  requires  players  to concentrate  intensely  in  order  to  hit  or  field  it successfully because of the difficulty of seeing it clearly. During games when a light colored ball is used, it is much more visible and players are able to hit and field it better because they are used to practicing with the two colored practice ball.

Title: Method for evaluation of polymorphic genetic sequences, and the use thereof in identification of hla types
Inventor: GREEN RONALD J
IPC: C12Q1/68
Filed: 1996-12-19
Abstract: The allelic type of a polymorphic genetic locus in a sample is identified by first combining the sample with a sequencing reaction mixture containing a polymerase, nucleoside feedstocks, one type of chain terminating nucleoside and a sequencing primer to form a plurality of oligonucleotide fragments of differing lengths, and then evaluating the length of the oligonucleotide fragments. As in a standard sequencing procedure, the lengths of the fragments indicate the positions of the type of base corresponding to the chain terminating nucleotide in the extended primer. Instead of performing and evaluating four concurrent reactions, one for each type of chain terminating nucleotide, however, the sample is concurrently combined with at most three and preferably only one, sequencing reaction mixtures containing different types of chain terminating nucleotides. The information obtained from this test is evaluated prior to performing any additional tests on the sample. In many cases, evaluation of the positions of only a single base using one sequencing reaction will allow for allelic typing of the sample.

Filed: 1997-01-20
Abstract: The invention related to a process for producing pipes, especially large pipes, according to the UOE process, wherein a pipe, after internal and external seam welding, is incrementally calibrated by cold expansion up to half the pipe length. The cold expansion is simultaneously used for straightening. For this purpose, the pipe is clamped at the shortest possible distance in front of an expander head, the free pipe end is flexibly deformed, and the pipe is then cold expanded in a known manner. The prestress force thereby decreases and then, after the release of the clamping and the remaining prestress, the pipe moves incrementally by the amount of and expander step width, up to half of the pipe length. The process is then repeated for the second half of the pipe.
