Patent CA-2415766-A1 (CA)
Inventor: GARDESKI KENNETH C
IPC: A61M25/00
Filed: 2001-07-10
Abstract: A deflectable tip introducer or guide catheter optimized for placement of leads or catheters within the vasculature of the human body is disclosed. The introducer includes inner and outer concentrically located tubular sheaths.  The inner and outer sheaths are preferably provided with different curved configurations, allowing the over-all displayed curvature of the introducer over its distal portion to be adjusted by longitudinal movement of the inner and outer sheaths relative to one another. The outer sheath may be fabricated of a thin tube of polyetheretherketone (PEEK) or other material having a relatively large stiffness as compared to the inner sheath. The outer sheath is sized to fit closely around the inner sheath. The inner sheath may be formed of a reinforced polyurethane, and preferably has a thin wall that is of about .005 inches in thickness or less. When supported by the inner sheath, the outer sheath transfers torque along the composite introducer assembly and serves to modify the curved configuration displayed by the distal end of the introducer assembly in conjunction with the relative longitudinal movement of the inner and outer sheaths.

Abstract: Compositions and methods are provided for inducing death of cancer cells through apotposis mediated by the death ligand, TRAIL. The method comprising : introducing an expression vector into a group of cells comprising cells that  express a receptor for TRAIL. The expression vector comprises a polynucleoti de sequence encoding TRAIL whose expression is preferably regulated by a conditional promoter in the vector. The cells into which the expression vect or is introduced express TRAIL when conditions are suitable to activate the conditional promoter. The expressed TRAIL induces cell death in those cells which express the TRAIL receptor through interaction between TRAIL and the receptor such as DR4 and DR5. The method can be used for treating tumors sit e- specifically and in a dose-adjustable manner.

Title: Pampers easy disposal
Inventor: SALTAJI SENAN
IPC: A61F13/551
Filed: 2003-05-07
Abstract: The invention relates to a rolled up plastic bag that will be placed (or other material) on the edges of the pampers waste, under the coverings (around the waste). Where once the pampers is ready to be thrown out, rather then every mother going looking everywhere for a plastic bag to place the dirty pampers in, now they can just roll down the plastic bag that is stock to the pampers, turn over the pampers into the plastic back, that is now placed on the pampers around the edges, and tie the bag and toss it in the garbage. And again, these are rolled up disposable bags, that wont make a difference in regard to the comfort of the baby, but will make a difference in regards to the comfort and convenience of the mother, where the idea can be advanced to use special bags, that will keep the smell in also.   This invention is environmentally friendly, time consuming, and more convenient for every individual who cleans up after the kids. Where, the surveys showed, 93%  would favour such an invention, and believed it would be more convenient.

Abstract: A method and system to expand digital transmission capacity in a "tree and branch" coax distribution system employing distributed TV signal amplifiers (650). Specifically, a number of separate bands are used in a main feeder cable (624) that are frequency shifted and applied to a number of local coax distribution networks. In the preferred embodiment each of the local coax distribution networks (762, 766, and 770) use the same pair of upstream and downstream frequencies (116 and 120). Using identical pairs of upstream and downstream frequencies allows the use of a single standardized non-tuning end-user data interface (client modem 408), that can be connected to any of the local coax distribution networks.
