Publication number: 20230233766Abstract: Systems and methods for multi-chambered syringes are described. In some embodiments, a multi-chamber syringe includes a housing with an internal cavity and first and second plungers disposed at least partially within the internal cavity. The first and second plungers are slidably displaceable relative to the housing, and are associated with first and second chambers respectively. A barrier is disposed at least partially between the first and second plungers to form the first and second chambers. The barrier is slidably displaceable relative to the plungers and barrel to selectively place the first and second chambers including first and second materials respectively in fluid communication. When the barrier is displaced, the first and second materials mix in a combined volume of the first and second chambers. Displacing the first plunger, the second plunger, and the barrier may dispense the mixed materials from the combined volume.Type: ApplicationFiled: June 22, 2021Publication date: July 27, 2023Applicant: Davol Inc.Inventors: Jonathan Bruce Trexler, Keith A.

Publication number: 20220409356Abstract: An implantable prosthesis for repairing a defect in a muscle or tissue wall. The prosthesis comprises a body of biologically compatible prosthetic material having a preformed three-dimensional contoured shape that independently assumes a three-dimensional curved shape configured to conform to the muscle or tissue wall. The body may be formed of a mesh fabric employing a knit construction. The body may be configured with one or more mechanical characteristics, individually or in any combination, having defined properties which may enhance the ability of the prosthesis to be handled in a surgical, robotic environment while meeting the performance and physical characteristics for soft tissue repair and reconstruction. One or more visual indicia may be provided to facilitate positioning and/or placement of the prosthesis at the muscle or tissue wall.Type: ApplicationFiled: July 11, 2022Publication date: December 29, 2022Applicant: Davol Inc.Inventors: Augustus Felix, Talia D’Ambruoso, Cuixiang Qu Spinney, Korel Cudmore
