Abstract: The present invention relates in general to anchoring systems for occluder devices, and more specifically, to an anchoring system and method for implanting an occluder device within a left atrial appendage (“LAA”) of the heart. The anchoring system is configured so that an anchor penetrates the inner endocardium layer, middle myocardium layer, and outer epicardium layer of an LAA wall. The purpose of the present invention is to provide an occluder device anchor that has a low risk of embolization and/or causing injury to neighboring valve structures. An additional purpose of the present invention is to provide an anchoring system and method for implanting an occluder device within the LAA that allows for the occluder device to be retrievable after initial placement, reusable, and repositionable for an optimal final placement within the LAA.

Abstract: This document discusses apparatus and methods for removing boundary air of a web that can interfere with slot die coating of a surface of the web. In an example, an apparatus for removing boundary air that can interfere with slot die coating a web can include a blade bar configured to attach adjacent an up-web side of a slot die vacuum box. The blade bar can include a channel configured to extend across a width of web, the channel including two sidewalls each having a surface configured to allow the web to pass between the surface and a machine roller with a consistent gap, a distribution chamber pneumatically coupled to the channel, and a vacuum connector configured to allow a source of vacuum to couple with the blade bar and apply vacuum to the vacuum distribution chamber.

Abstract: A web threading and splicing system that provides easy access to the threading rolls by an operator. The new web supply roll for replacement of the expired web can be threaded at a standstill position adjacent the operator. This affords ease of access, which furnishes a great ergonomic and safety advantage, wherein the operator does not have to reach into moving web components in order to accomplish the splice.

Abstract: The present invention features a web feeding and transition system for exchanging a first, used, web roll for a second, fresh, web roll, so that web material is conveyed along a web-conveying feed path. Each web of the first and second web rolls includes a backing or a separate, interleaved web. The web assembly has a first work station having a mounting for allowing the first web roll to unwind and feed the first web to the feed path. A second work station has a mounting adjacent the first mounting for allowing the second web roll to unwind so that the second web may be spliced to the first web. A "bump splicing" vacuum roll disposed upon the first work station causes an adhesive section of the fresh web to contact an end portion of the exhausting web, as the web roll runs out.

Abstract: The present invention features a web feeding and transition assembly for exchanging a first, used, web roll for a second, fresh, web roll, so that web material will be continuously conveyed along a web-conveying feed path. Each web of the first and second web rolls includes a backing or a separate, interleaved web. The transition assembly has a first mounting for allowing the first web roll to unwind and feed the first web to the feed path. A second mounting adjacent the first mounting allows the second web roll to unwind so that the second web may be spliced to the first web. A "bump splicing" unit causes an adhesive section of the second web to contact an end portion of the first web, as the first web roll runs out. Thus, a continuous web feed is accomplished by splicing the first and second webs "on the fly"; the new, incoming roll is caused to match the speed of the expiring roll within one revolution.
