  • Patent number: 8545754
    Abstract: Disclosed is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit. The apparatus has an inlet and an outlet that is located radially outward from the inlet in order to define a flowpath through the apparatus. The apparatus comprises: a core that is substantially centrally located in the apparatus and to which blood from a patient can be supplied through the inlet; a heat exchanger comprising a plurality of heat transfer elements that are arranged around the core and between which blood from the core can move radially outward; and an oxygenator comprising a plurality of gas exchange elements that are arranged around the heat exchanger and between which blood from the heat exchanger can move radially outward before exiting the apparatus through the outlet.

  • Publication number: 20100272606
    Abstract: Described is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit comprising: an inlet mandrel that is configured such that the blood moves radially outward from the inlet mandrel through the openings in a radial direction; a heat exchanger arranged around the inlet mandrel, wherein blood can move radially outward with the transfer of heat to or from the blood; an oxygenator arranged around the heat exchanger, wherein blood can move from the heat exchanger radially outward with the transfer of oxygen into the blood; and a housing that houses the inlet mandrel, the heat exchanger and the oxygenator, and that comprises a blood inlet in communication with the inlet mandrel in order to allow blood to enter the apparatus from the patient, and a blood outlet in communication with the oxygenator in order for blood to exit the apparatus, wherein the blood outlet is located in the housing radially outward from the inlet.

  • Publication number: 20100269342
    Abstract: Described is a method of making an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit, the steps comprising: providing a core through which blood can be supplied to the apparatus from a patient; providing a heat exchanger about the core such that blood from the core can move radially outward through the heat exchanger; providing an oxygenator about the heat exchanger such that blood from the heat exchanger can move radially outward through the oxygenator; and placing the core, heat exchanger and oxygenator in a housing that includes an inlet in communication with the core and an outlet that is located radially outward from the inlet in order to define a flowpath for blood through the apparatus.

  • Publication number: 20100272607
    Abstract: Described is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit, the apparatus having an inlet and an outlet that is located radially outward from the inlet in order to define a flowpath through the apparatus, the apparatus comprising: a core in communication with the inlet such that blood from a patient can be supplied to the core, the core comprising a first element and a second element that interfit to define openings, wherein the elements and the openings together enhance flow of blood from the patient radially outward from the core; a heat exchanger that is arranged about the core and through which blood from the core can move radially outward; and an oxygenator that is arranged about the heat exchanger and through which blood from the heat exchanger can move radially outward before exiting the apparatus through the outlet.

  • Patent number: 7622129
    Abstract: Polymeric materials and processes for making the same are provided herein wherein said polymeric materials have nano-sized topological features or textures. These features have dimensions in various ranges including, but not limited to, dimensions less than about 100 nanometers. In addition, polymeric materials are described herein that have a surface roughness of about 50 nm or greater. These polymeric materials are useful for making implants for soft tissues, such as bladder tissue replacement implants. Methods of treatment using such implants are also described. In such methods, polymers that are biocompatible, and biodegradable are also described.
