Abstract: A header for use in implantable pulse generator devices. The header is part of electrical connector assembly having one or more openings designed to receive the terminal pin of an electrical lead wire or electrode. The header is designed to provide and sustain long-term electrical and mechanical lead wire connections between the electrodes of a terminal pin and the implantable pulse generator device.

Abstract: A multi-foil ringlet in combination with a cylindrical housing provides advantageous results when employed as a contact of a header of an implantable pulse generator. The multi-foil ringlet provides a superior electrical connection between the header and a lead pin inserted into the header.

Abstract: A connector for electrically and mechanically coupling a lead pin to a pulse generator that includes a housing and a plunger having openings which can be aligned in an unlocked position to permit insertion and retraction of the lead pin. The connector also has a biasing member which moves and then holds the plunger in a locked position relative to the housing such that the housing and plunger pinch the lead pin thereby coupling the lead pin to the connector.

Abstract: A barrier sheet having a first side and a second side, a top edge, a bottom edge, and a laterally located midpoint, wherein the sheet is folded along its length to form a folded sheet defined by at least one fold with an adhesive strip positioned at a predetermined distance from the top and bottom edges, and preferably approximately at the sheet midpoint. When making a roll of barrier material, a barrier sheet material is provided and folded at least once laterally. The sheet then incorporates an adhesive strip applied to one side of the sheet at a predetermined distance from the top and bottom ends, preferably approximately at the midpoint. The adhesive strip is oriented lengthwise such that when the sheet is unrolled from the roll and unfolded, the strip will approximately bisect the sheet lengthwise. The sheet is then folded in a predetermined fashion, and rolled onto a roll.

Abstract: A coated paper product including a paper layer and a polymer layer, wherein the polymer layer includes a polylactide polymer composition having a ratio of Mz to Mn of greater than about 6. The polymer composition, when melted, exhibits a die swell of greater than about 1.25 for a melt flow index of greater than about 2. Polymer lactide compositions, methods of manufacturing the polymer composition and the coated paper product, and articles produced therefrom are also described.

Abstract: A process for the continuous production of polylactide polymers from lactic acid which incorporates removal of water or a solvent carrier to concentrate the lactic acid feed followed by polymerization to a low-molecular-weight prepolymer. This prepolymer is fed to a reactor in which a catalyst is added to facilitate generation of lactide, the depolymerization product of polylactic acid. The lactide generated is continuously fed to a distillation system as a liquid or vapor wherein water and other impurities are removed. The resultant purified liquid lactide is fed directly to a polymerization process.

Abstract: A process for the continuous conversion of crude lactic acid to a substantially purified lactide or polylactide including the steps of polymerizing the lactic acid to form a prepolymer with subsequent depolymerization to form a crude lactide in the presence of a catalyst. The crude lactide is purified in an improved distillation system in which at least three fractions are formed with the substantially purified lactide removed as an intermediate boiling sidedraw stream. The substantially purified lactide may then be polymerized.
