The central portion of the wire is annularly wound within the annular groove to define a coil. The coil is configured to at least one of radially expand and contract upon rotation of the distal housing relative to the proximal housing.

Abstract: A surgical stapling apparatus includes a buttress retention assembly. The buttress retention assembly includes a sleeve configured to be detachably coupled with a first jaw member of a tool assembly of the surgical stapling apparatus, and a buttress material. The sleeve includes a proximal hook extending transversely outward from a lateral side of the sleeve, and a mouth including a hook configured to be received in a knife slot of the first jaw member. The mouth includes an inner surface having an inwardly extending boss. The buttress material includes a tab extending transversely outward from a lateral side thereof. The tab defines a proximal slot configured to receive the proximal hook of the sleeve. At least a portion of the distal end portion extends through the mouth of the sleeve. The distal end portion defines a distal slot dimensioned to receive the boss of the sleeve.

Abstract: Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

Abstract: A medical device communication system with a modular design to communicate with different types of medical devices, such as physiological sensors. The modular design is implemented using an extensible software library that provides a uniform framework for various applications or third party applications access to medical device data. The modular design also allows for regulated and unregulated portions of the system to be integrated into the system while allowing each portion to be updated separately. The regulated portion of the system may include components, such as sensors and the software library, that are subject to regulatory approval while the unregulated portion may include applications that are not subject to regulatory approval. Thus, the system enables a third party application developer to avoid having to submit the application to a regulatory agency for an application making use of the sensor data.
