Patent number: 11432939Abstract: Various spinal implants and methods for stabilizing the spine are provided. In one exemplary embodiment, a spinal implant is provided having an expandable container with an interior volume that is selectively expandable between a compressed condition and an expanded condition. The expandable container is coupled to a superior endplate member having a bone-contacting surface and an engagement surface effective to mate with a superior surface of the expandable container, and an inferior endplate member having a bone-contacting surface and an engagement surface effective to mate with an inferior surface of the expandable container. In addition, at least one inlet port is formed in the expandable container and is effective to communicate a fluid to at least one cavity disposed within the interior volume of the expandable container.Type: GrantFiled: January 7, 2020Date of Patent: September 6, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Naren Renganath, Steve Connolly, Michael A.

Patent number: 9482351Abstract: The present invention relates to a process for the sterile transfer of fluids, be they liquids or gases. It uses a presterilized device comprised of a body having a bore formed through at least a portion of its interior. Contained within the bore is a movable plunger. The body has a first and a second end. The first end contains a face designed to be attached to the upstream component. The second end is connected to a downstream component such as a filter, pipeline, sample bag and the like. The plunger has corresponding first and second ends. The first end of the plunger when it the closed position is in alignment with the face of the body which combined form a steamable surface and a sterile barrier against the environment to the rest of the interior of the body, the plunger and downstream components. The device is attached to an upstream component and the face and the first end of the plunger are steam sterilized in place.Type: GrantFiled: August 21, 2013Date of Patent: November 1, 2016Assignee: EMD Millipore CorporationInventors: Stephen Proulx, Joseph Almasian, Naren Renganath, Stephen Tingley, Martin Morrissey
