A chemical component mixing apparatus for use with a fluid source in creation of a concentrated solution mixture is described. The mixing apparatus includes at least one mixing station. The mixing station includes an injector assembly, where the injector assembly includes at least one venturi chamber having at least one suction port in fluid communication with the at least one venturi chamber. The apparatus also includes at least one super concentrate chemical component housed within a chemical container, where the chemical container is fluidly connected by a first tube to the at least one venturi chamber via the at least one suction port, a receiving container fluidly connected to the injector assembly via a second tube, and a fluid source inlet introducing a fluid into the at least one mixing station, where the pressure within the at least one mixing station is less than 150 psi. The fluid passes through the at least one venturi chamber, thereby drawing the at least one super concentrate chemical component into the venturi chamber, and the concentrated solution mixture is dispensed from the injector assembly into the receiving container.

Chemical mixing system and method

A method for closing an opening in soft tissue inside the body includes the step of making an incision in the body for permitting access to the interior of the body generally adjacent to the location of the opening in the soft tissue inside the body. An instrument is inserted through the incision to the vicinity of the opening in the soft tissue, and passes through the soft tissue and across the opening in the tissue generally from the first side of the opening to a second side of the opening opposite the first side. At least a part of the instrument lies in a passage in the soft tissue. A first leg of a generally H-shaped suture is pushed generally lengthwise in the instrument into the passage with the first leg and a cross member connecting the first leg to a second leg being resiliently deflected from their relaxed positions relative to one another. The first leg moves back to its relaxed position relative to the cross member upon passing out of the instrument, and extends transversely with respect to the lengthwise extension of the passage across the exit thereof so that the first leg cannot move back into the passage. The second leg extends generally transversely with respect to the lengthwise extension of the passage across the entrance thereof so that the second leg cannot move into the passage. The cross member is disposed in the passage and is sized so that the legs of the suture compress the opening shut. In another aspect, a method for repairing a tear formed by separation of the soft tissue from the bone in which a suture is inserted through the bone and tissue, and across the tear.

Method for repairing tears and incisions in soft tissue

A system for repairing a tear in the meniscus in the knee joint including a suture having a first leg, a second leg spaced from the first leg and a cross member connecting the first and second legs. An instrument for delivering the suture to the meniscus can be inserted through an incision in the knee and into the vicinity of the meniscus. A first end of the instrument enters the meniscus adjacent to a first side of the tear, passes through the meniscus and exits the meniscus on a second side of the tear in the meniscus generally opposite the first side of the tear. The instrument has a channel extending longitudinally of the instrument in which the first leg of the suture can be inserted. A push rod pushes the first leg and cross member generally lengthwise in the channel and into the meniscus where the suture closes the tear.
