Patent number: 11779519Abstract: The invention provides, in some aspects, a container system for medical solutions such as peritoneal dialysis (PD) solutions. The invention particularly features a system which includes a first compartment that contains a first medical solution, e.g., a PD osmotic agent, and a second compartment that contains a second medical solution, e.g., a PD buffer agent. The compartments maintain their respective contents separately from one another for purposes of transport, storage and/or sterilization. However, the compartments are fluidly couplable, so that their respective contents can be combined with one another, e.g., following sterilization of the agents and prior to their introduction into the patient's abdomen. To that end, a container system can include a diffuser that is disposed in a fluid pathway between the first and second compartments, e.g., to facilitate homogeneous mixing of the first and second PD agents.Type: GrantFiled: October 9, 2020Date of Patent: October 10, 2023Assignee: FRESENIUS MEDICAL CARE HOLDINGS, INC.Inventors: Lynn E.

Patent number: 11738159Abstract: An aerosol generator is positioned adjacent to a patient as an attachment to a trocar. The trocar has an entry port for insufflation gas. Aerosol generated by a vibrating element is entrained in the insufflation gas and the mixture is delivered through the trocar. The aerosol may contain a medicament. The trocar may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolized medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolized medicament to the pneumoperitoneum regions. The surgeon can temporarily remove the camera from the trocar port to facilitate insertion and positioning of the aerosolizing unit.Type: GrantFiled: November 6, 2020Date of Patent: August 29, 2023Assignee: Aerosurgical LimitedInventors: Patrick Joseph Power, Conor Paul Duffy
