Patent number: 11490790Abstract: The present embodiments provide systems and methods suitable for delivering an agent including a plurality of particles to a target site. In example embodiments, a system suitable for delivering an agent to a target site includes a catheter having a first wall defining a lumen sized for delivery of the agent to the target site. The catheter has a distal end terminating with a primary opening of the lumen, an opposing proximal end, and a longitudinal axis extending between the distal end and the proximal end. At least one secondary opening is formed at the distal end, wherein the secondary opening is configured to allow fluid to flow through the secondary opening to create a steady flow of fluid at an angle with respect to the longitudinal axis and prevent the plurality of particles from flowing through the secondary opening.Type: GrantFiled: July 11, 2019Date of Patent: November 8, 2022Assignee: Cook Medical Technologies LLCInventors: John Crowder Sigmon, Jr., Gregory James Hardy, Shaun Davis Gittard

Patent number: 11439384Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.Type: GrantFiled: April 25, 2019Date of Patent: September 13, 2022Assignee: Muffin IncorporatedInventors: Shaun Davis Gittard, John C.
