  • Publication number: 20240082017
    Abstract: An implant delivery device may include an implant holding portion proximate the distal end, the implant holding portion being configured to retain a sheet-like implant during implantation of the implant. In addition, the implant holding portion may be configured to receive the implant with a fixed implant supporting flange member configured to support the implant on one side, and a movable implant supporting flange member. The movable implant supporting flange member may be configured to be slidable between a distal position and a proximal position, wherein, in the distal position, the movable implant supporting flange member and secures the implant against the fixed implant supporting flange member, and in the proximal position, the movable implant supporting flange member is withdrawn from the distal end of the implant delivery device, thus enabling release of the implant.

  • Patent number: 11911535
    Abstract: An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.

  • Publication number: 20230329761
    Abstract: An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A wing actuation tool is slidably engaged in a central passage of the elongated main body to fix the implant to the elongated main body. The wing actuation tool temporarily attaches to the implant allowing for deployment and retraction of wings of the implant during surgery. Longitudinal translation of the wing actuation tool deploys an actuation plunger of the implant.

  • Publication number: 20230320865
    Abstract: An interbody spacer for a spine includes a housing having a plurality of clearance holes configured to engage bone of the spine. A contact plate including a plurality of apertures is positioned a distance away from the housing configured to engage bone of the spine. A plurality of rivets adjoin the housing and the contact plate. A plurality of springs are included with each spring configured to encircle a respective rivet and translate the distance between the housing and contact plate from a minimum distance to a maximum distance.

  • Publication number: 20230157724
    Abstract: A surgical cannula includes a seal structure including a one-way check valve and a cannula body. The cannula body includes an insertion portion having a distal opening that is configured to be inserted into tissue, and a receiving portion that includes a proximal opening and is configured to reversibly receive the seal structure. In addition, the seal structure is configured to removably associate with the proximal opening of the cannula body, retain a positive pressure within the cannula body when engaged with the cannula body, and retain a positive pressure within the cannula body when an object is inserted through the cannula and the seal structure. Also, the cannula further includes one or more suture attachment structures extending outward laterally from the cannula body; and one or more internal recesses in an inner wall of the cannula located directly adjacent to the one or more suture attachment structures.

  • Patent number: 11559330
    Abstract: The present disclosure relates to a surgical cannula with a removable seal at one end. The surgical cannula is a wide gauge surgical cannula, that allows materials and tools to be introduced into a body during a surgical procedure. The cannula includes a seal structure at one end, which may be attached to and detached from the cannula body as desired. The seal structure includes one or more valves that retain pressure within the cannula. The one or more valves are configured to allow a tool through the valve(s), while retaining pressure inside the cannula, so that surgical tools may be inserted through the cannula even when the seal structure is attached to an end of the cannula.

  • Publication number: 20230015890
    Abstract: An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A plunger is slidably engaged in a central passage of the elongated main body configured to fix the implant to the elongated main body by selectively filling the central passage within the distal portion. A hex nut driver is concentrically located about the plunger and elongated main body to deploy an actuation plunger of the implant. The proximal handle portion of the main body includes a staggered path therethrough for accepting a tab of the plunger therein. Advancement and retraction of the plunger tab within the staggered path alternates the insertion instrument between an unlocked position configured to mount the implant on the distal portion of the elongated main body, a locked position configured to lock the implant on the distal portion, and a deployed position configured to secure the implant.
