Abstract:
The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.
Abstract:
A polymer composition comprises a polyolefin and a nucleating or clarifying agent dispersed or dissolved in the polyolefin. Methods for producing the polymer composition and method for producing articles from the polymer composition are also described. Molded polymer articles and polymer film may be manufactured using the compositions of the invention.
Abstract:
A lead anchor includes a body defining a lead lumen having a first opening and a second opening through which a lead can pass. The body further defines a transverse lumen that intersects the lead lumen. An exterior member is disposed around at least a portion of the body. The exterior member is formed of a biocompatible material. A fastener anchors the lead to the body through the transverse lumen by deforming a portion of the lead. The transverse lumen is configured and arranged to receive the fastener. At least one suture element is defined by the exterior member and is configured and arranged for receiving a suture to suture the lead anchor to patient tissue.

Abstract:
An insertion kit for percutaneously implanting an electrical stimulating paddle lead into a patient includes a paddle lead introducer. The paddle lead introducer facilitates percutaneous implantation of a paddle lead into the patient. The paddle lead introducer includes a sheath and a dilator. The sheath is insertable into the patient. The sheath is configured and arranged to receive a paddle lead during implantation of the paddle lead into the patient. The sheath can divide into at least two parts for removal of the sheath from the paddle lead upon implantation of the paddle lead. The dilator is insertable into the sheath. A first end of the dilator defines an aperture at a tip of the first end. The first end of the dilator has a transverse circumference that increases from the tip towards a second end.
Abstract:
A lead anchor includes a body defining at least one first portion of a lead lumen, the body having a first opening and a second opening. An obstructing member is disposed within the body. The obstructing member defines a second portion of the lead lumen.
