Patent CA-2723595-A1 (CA)
Inventor: RAGSDALE CHARLES W
IPC: C12M1/42
Filed: 2009-05-08
Abstract: Adherent cells and other membranous structures that are immobilized on a solid surface are transfected by electroporation in which the electric field is produced by a array of closely spaced electrodes positioned above the surface.  Each electrode is substantially smaller in at least one lateral dimension than the dimensions of a single cell, and the electrodes in each pair are spaced apart by distances selected such that a maximum of one cell will reside within the field produced by each pair, and the distance of the electrodes above the surface to which the cells are adherent is small enough to place the cell within the resulting electric field and yet great enough to avoid contact of the electrodes with the cell membrane.

Title: Method and apparatus pertaining to a flexible wrapping material having laser-formed crease lines
Inventor: EXNER RON
IPC: B31B50/25
Filed: 2011-02-16
Abstract: One or more lasers (80, 100) form one or more crease lines (140, 150, 151) in a flexible wrapping material (60). The flexible wrapping material is then folded about the one or more crease lines when encapsulating an item to be wrapped within the flexible wrapping material. The flexible wrapping material may have poor dead-fold characteristics and can comprise a flow-wrapping material. A single laser or multiple lasers can serve to form the one or more crease lines. The crease lines can be formed on a same side of the flexible wrapping material or on both sides thereof. By one approach, folding the flexible wrapping material about the one or more crease lines forms, at least in part, a form- factor conformal pocket to accommodate the aforementioned item. By another approach, folding the flexible wrapping material about the one or more crease lines forms, at least in part, a gusset.

Abstract: An elastic bladder is provided that is in constant fluid communication with the expandable balloon portion of a gastric band in order to automatically and continuously adjust the gastric band. The fluid pressure between the bladder and the balloon portion of the gastric band automatically and continuously adjusts so that there is no lasting pressure differential between the bladder and the expandable balloon. As the level of restriction imparted by the gastric band on the stomach of the patient changes, fluid from the bladder automatically and substantially instantaneously flows to or from the expandable balloon portion of the gastric band thereby maintaining neutral fluid pressure equilibrium between the bladder and the balloon and automatically adjusting the band to the correct level of restriction to keep the patient in the optimum zone for weight loss.
