  • Patent number: 10576208
    Abstract: A delivery system for delivering medical or pharmaceutical compounds includes a container, a closure element, an attachment element and a penetration element. The container contains the compounds and has a closed container bottom and an open second end. The closure element makes fluid-tight contact with the inner wall of the container. The penetration element has a hollow needle and moves along the longitudinal axis of the container. The penetration element includes a first link motion portion, and the attachment element includes a second link motion portion. One of the link motion portions is a projection, and the other is a guiding groove. As the projection moves in the guiding groove, the hollow needle of the penetration element moves towards the container bottom and penetrates the closure element. The penetration element moves inside the attachment element towards the container bottom based on how the projection travels in the guiding groove.

  • Patent number: 10525186
    Abstract: A method of performing regional citrate anticoagulant dialysis of a patient's blood includes flowing blood from and back to the patient through an extracorporeal circuit including a dialyzer having semi-permeable dialysis membranes and a dialysate chamber surrounding the membranes. The method further includes flowing a dialysate containing calcium and citrate through the dialysate chamber of the dialyzer and introducing citrate into the patient's blood upstream of the dialyzer, whereby the patient's blood is dialyzed. The method can further include predicting the concentration of systemic ionized calcium in the blood of the patient at any point in the dialysis treatment or post-dialysis, such as by a mathematical model. The method can further include statistically correcting the preliminary predicted post-dialysis concentration of systemic ionized calcium in the patient's blood to provide a final predicted post-dialysis systemic ionized calcium concentration.

  • Patent number: 10518069
    Abstract: An implantable valve assembly including a drainage catheter having a central lumen transitioning into a plurality of distinct branch lumen made of a shape memory material. A bioabsorbable dip coating secures the distal end of the plural distinct branch lumen together in physical contact with one another. Each branch lumen has an outer perimeter comprising at least one of a first outer surface section and a second outer surface section. In a secured state with the plural distinct branch lumen held together by the dip coating fluid is prohibited from passing through the holes defined in the first outer surface section. Bioabsorbable blocking members disposed about the outer perimeter of the assembled branch lumen mask holes defined in the second outer surface section prohibiting fluid from entering therein. In a time staggered fashion, the bioabsorbable elements absorb exposing new holes through which the fluid drains.

  • Patent number: 10456565
    Abstract: A drainage catheter system includes an elongate tube with proximal and distal ends and a filament extending the tube that is adjustable to create a closed loop at the distal end of the tube when the filament is retracted relative to the tube. The filament is coupled to the tube such that the filament and tube are prevented from being separated in the event that the tube and filament are cut at the proximal end at the conclusion of a drainage procedure. The filament can be attached to the tube near the distal end. The filament can be attached to the tube along its length. The catheter system can also include a retraction mechanism having a first fixed position and second fixed position, where the second fixed position retracts the filament proximally relative to the first fixed position by actuating a plunger.
