Patent number: 11724085Abstract: Systems and methods of disinfection of catheter connections are provided. A transfer catheter connector can include a UV-transparent window at its distal end and a sealing plunger proximal to the UV-transparent window. A solution set connector can be inserted inside a portion of the transfer catheter connector to connect a solution set and transfer catheter. The solution set connector comprises a lumen covered by a leading membrane surface; a sealing surface configured to sealingly engage the window surface, and a piercing member configured to pierce the membrane surface. The sealing plunger, membrane surface, and window define a disinfection zone. The connectors can be connected in a disinfection position configuration in which flow is not permitted between the catheters and the connectors are irradiated with UV light. After disinfection, the connectors are advanced to a flow position in which the piercing member pierces the membrane surface, enabling flow between the catheters.Type: GrantFiled: March 17, 2021Date of Patent: August 15, 2023Assignee: PURACATH MEDICAL, INC.Inventors: Justin A. Lance, Stephen Bower, John E. Ashley, Jeffrey Etter, Julia A. Rasooly, Michael Rasooly, Benjamin S. Arnett

Patent number: 11564806Abstract: A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.Type: GrantFiled: March 25, 2020Date of Patent: January 31, 2023Assignee: Howmedica Osteonics Corp.Inventors: Damien J. Shulock, John E. Ashley, Thomas Grotz, Rudy Pretti

Publication number: 20220226127Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.Type: ApplicationFiled: November 24, 2021Publication date: July 21, 2022Inventors: John E. Ashley, Philip J. Simpson, Walter Dean Gillespie, David G. Matsuura, George A. Mansfield, III

Patent number: 10702397Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.Type: GrantFiled: June 4, 2018Date of Patent: July 7, 2020Assignee: Howmedica Osteonics Corp.Inventors: Philip J.

Patent number: 10428446Abstract: A woven flame-resistant fabric for garments, the warp and fill yarns being made up of at least about 30 wt. % inherently flame-resistant fibers. The fabric is woven from a plurality of warp yarn groups consecutively arranged across the width direction in a recurring pattern, each warp yarn group consisting of a plurality of adjacent consecutively arranged warp yarns. At least one warp yarn in each warp yarn group is woven with the fill yarns in a plain (1/1) weave and at least one warp yarn in each warp yarn group is woven in one or more non-plain weaves each selected from the group consisting of 1/2, 2/1, 2/2, 1/3, and 3/1. Approximately half of the warp yarns in the fabric are woven in a plain (1/1) weave and the remaining warp yarns in the fabric are woven in the one or more non-plain weaves, in an alternating fashion.Type: GrantFiled: August 31, 2017Date of Patent: October 1, 2019Assignee: Milliken & CompanyInventors: Ansel L.
