Patent CA-2336174-A1 (CA)
Inventor: JOLIVET MICHEL
IPC: G01N33/53
Filed: 1999-07-05
Abstract: The invention concerns a method for diagnosing a prostate adenocarcinoma in a male human patient without performing prostatic biopsy, using the PSA protein (prostate specific antigen) present in the patient's blood, serum, urine or seminal liquid. The method consists in: a) measuring the free PSA total level, that is cleaved or non-cleaved; b) measuring the level of all or part of the cleaved free PSA; c) calculating the proportion of cleaved free PSA relative to the total free PSA; and d) diagnosing that the patient suffers from: a prostate adenocarcinoma, when said ratio is not more than a reference value; a benign prostate pathology, such as benign prostatic hypretrophy, when said ratio is higher than the reference value. It is also possible to calculate the proportion of non-cleaved free PSA relative to the free PSA total or the proportion of cleaved free PSA relative to the non-cleaved free PSA or to the total PSA or to the complexed PSA or to establish a ratio between those proportions. The invention is applicable to diagnosis of adenocarcinoma or benign prostatic hypertrophy.
Patent CA-2337483-A1 (CA)
Inventor: HEISMANN BJORN
IPC: H01P3/02
Filed: 1999-07-05
Abstract: According to the invention a resistive current limiter contains an electrically insulating support element (3) and at least one printed conductor structure (10) positioned thereon which comprises a printed conductor (11) made of a high-Tc superconductive material. The printed conductor has straight and curved sections (11g and 11b, respectively). In the curved sections (11b) a maximum internal radius/external radius ratio v of 7 is to be maintained (v = ra/ri, where ra = external radius, ri = internal radius). The printed conductor (11) is advantageously obtained by structuring from a layer made of the high-Tc superconductive material which has been deposited on the support element (3).

Title: Extended release buccal bioadhesive tablet
Inventor: BOLOGNA WILLIAM J
IPC: A61P15/10
Filed: 1999-08-24
Abstract: A bioadhesive tablet wherein the active ingredient may be protected from water or the surrounding environment, thereby protecting it from metabolism or from other degradation caused by moisture, enzymes, or pH  effects, and making it bioavailable only at a controlled rate. The active ingredient may be protected from moisture during the manufacturing process and more importantly may be protected from moisture and the immediate septic environment until after the patient has applied the tablet, and then only at a slow and controlled rate. It is by this process of progressive hydration that the active ingredient remains protected for many hours after administration.      It is also by the process of progressive hydration that controlled and sustained release is achieved because only that part of the active ingredient that is the hydrated (aqueous) fraction of the tablet is available for absorption (bioavailable).

Title: Spinal fixation system
Inventor: MULLANE THOMAS S
IPC: A61B17/70
Filed: 2000-01-24
Abstract: An adjustable spinal fixation system comprises a collection of anchoring assemblies attached, via a variety of connectors, to spine-stabilizing rods. The anchoring assemblies include a linking member attached in a ball-and-socket fashion to a bone-engaging member that is adapted to engage a spinal bone of a patient.  The linking member joins one of the included connectors to an associated bone-engaging member. The connectors are selectively attached to one of the stabilizing rods. The anchoring assemblies each include a support collar and a retention collet that cooperate to allow adjustment of the bone-engaging member and corresponding connector during surgery. When surgery is complete, a securing nut and locking bolt cooperate with the support collar and retention collet to maintain the relative position of the entire fixation system, preventing unwanted movement between the system components.  In one embodiment, the connectors are multi-piece units that may be added or removed without disturbing adjacent connectors.

Inventor: KELLER ULLRICH
IPC: C12N9/00
Filed: 2000-06-15
Abstract: The invention relates to a method of modifying peptide synthetases in such a manner that they can N-methylate their substrate amino acids. PPS are enzymes that synthesize peptides in a non-ribosomal manner. PPS have a modular set-up.  Each module has an activation domain which recognizes and covalently binds to the respective substrate amino acid. The peptide synthesis catalyzed by PPS  proceeds by the condensation of the covalently bound substrate amino acids. A  minor number of the known activation domains is capable of also N-methylating the bound substrate amino acids. The inventive method allows conversion of the activation domains without N-methyl transferase activity to activation domains with N-methyl transferase activity while maintaining the original substrate specificity.

Inventor: SHARROW JAMES S
IPC: A61M3/02
Filed: 2000-08-18
Abstract: A device (100) and method for delivering an agent to the uterine cervix make use of a seal member (102) that defines a chamber (103) upon engagement with the cervix. An agent delivery port (106) in fluid communication with the chamber is provided for delivery of the agent to the uterine cervix. A vacuum port (117) in fluid communication with the chamber allows application and retention of vacuum pressure to the chamber. At least a portion of the seal member is deformable in response to contact with the outer surface of the uterine cervix and application of vacuum pressure. Upon deformation, the seal member substantially seals the chamber against leakage of the agent. The seal member may include a tacky skirt-like member that promotes adhesion of the seal member to the cervix, and enhances the effectiveness of the seal. In this manner, the device prevents leakage, thereby improving diagnostic or therapeutic effectiveness while reducing waste and expense. The device and method also can be adapted for introduction of surgical or diagnostic instruments, such as ablation catheters or endoscopes.
