Abstract:

A method of fabricating an annular liner for a combustion chamber of a gas turbine engine. The combustion chamber has a dome including a fuel nozzle for delivering fuel to the combustion chamber. A metal piece is formed into an annular section constituting at least a portion of the liner and having at least one seam extending generally axially with respect to an axial centerline of the liner. An upstream end of the liner is machined to have a registration feature for connecting the liner to the combustion chamber dome in at least one predetermined orientation with respect to the dome. Further, the method includes ensuring the registration feature and the seam are located relative to each other on the liner so the seam is at a preselected position with respect to the combustion chamber dome when the liner is connected to the combustion chamber dome in the predetermined orientation.

International Classification:

A61F 2/02

US Classification:

623 2372

Abstract:

An implantable tissue reinforcement device useful for treating or preventing the formation of parastomal hernias forming about a surgically created stoma. The tissue reinforcement device can comprise a synthetic or mammalian-derived sheet-like graft member, such as a resorbable material that promotes tissue ingrowth, wherein a sizing pattern is included that comprises linear indicia radiating outward from a stomal aperture. The linear indicia facilitate creation of a resized stomal opening in the graft member sufficiently large to allow passage of the resected bowel portion. A series of cuts made along the indicia create a plurality of flaps about the resized opening that are configured to abut the bowel portion and enhance reinforcement the stomal region after implantation. In one embodiment, the linear indicia comprises a series of weakened (e.g., perforated) lines that facilitate the cutting of the material by a scalpel, scissors, etc. The clinician resizes the stomal opening to a known diameter using reference indicia, such as diameter indicia and circular guide indicia. The sizing pattern can be imprinted on or etched into the material of the graft member, or it can be at least partially located on a separate template that is either laid over the graft member, preattached as a cuttable overlay, or used as a reference guide.

International Classification:

A61B 17/03

US Classification:

606213

Abstract:

The present invention provides, in certain aspects, devices and methods for plugging passageways and other open spaces in the body. In one embodiment, a plugging assembly comprises a first plug member and a second plug member, wherein the second plug member is configured to contact and move a portion of the first plug member in plugging a body passageway. These plug members may be formed with one or more of a variety of biocompatible materials including some that are naturally derived and some that are non-naturally derived. In another embodiment, such a plugging assembly is combined with a device that is suitable for delivering the assembly into a body passageway.

US Classification:

600 30

Abstract:

The embodiments described include graft devices for reinforcing patient tissue structures and methods of making and using the graft devices. In certain embodiments the graft devices have a remodelable extracellular matrix material graft body defining a slot and having a portion receivable through the slot to form a closed loop. Such graft devices can be used in encircling reinforcement of patient tissue structures such as anal sphincters or anastomosed vessel segments.

International Classification:

G06Q 20/20
G06Q 30/02

Abstract:

A system for verifying a price associated with an item in a retail environment includes a price tag having an optical member that includes an optical characteristic that modifies an amount of optical energy that leaves the optical member relative to an amount of optical energy received by the optical member, and a price tag holder including an optical sensor having an emitter and a detector. The emitter is positioned to emit optical energy onto the optical member and the detector is positioned to receive optical energy leaving the optical member. A computing device in operable communication with the optical sensor is operative to determine whether the price tag is accurate based upon a comparison between the amount of optical energy received by the detector and the amount of optical energy emitted by the emitter.

International Classification:

G03G 21/16

Abstract:

A system for customizing settings of an electronic device includes a replaceable component having an optical member for receiving optical energy. The optical member has an optical characteristic for modifying an amount of the optical energy that leaves the optical member relative to an amount of the optical energy received by the optical member. A support is located on an outer casing of the electronic device and the replaceable component is mountable on the support. The system further includes an optical sensor including a detector positioned to receive the amount of the optical energy leaving the optical member when the replaceable component is mounted on the support. A controller determines one or more predetermined settings to be applied to the electronic device based at least upon the amount of the optical energy received by the detector.
