Patent number: 8834344Abstract: A cannulation system for cardiac support uses an inner cannula disposed within an outer cannula. The outer cannula includes a fluid inlet for placement within the right atrium of a heart. The inner cannula includes a fluid inlet extending through the fluid inlet of the outer cannula and the atrial septum for placement within at least one of the left atrium and left ventricle of the heart. The cannulation system also employs a pumping assembly coupled to the inner and outer cannulas to withdraw blood from the right atrium for delivery to the pulmonary artery to provide right heart support, or to withdraw blood from at least one of the left atrium and left ventricle for delivery into the aorta to provide left heart support, or both.Type: GrantFiled: September 9, 2013Date of Patent: September 16, 2014Assignee: Maquet Cardiovascular LLCInventors: Walid Najib Aboul-Hosn, Jodi Akin, Michael Guidera, William R.

Patent number: 7381179Abstract: Pump and cannula systems inserted through the right side and/or left side of the heart provide protection against collapse of the heart chambers and veins and arteries and provide supplemental blood flow through same to enable beating heart or still heart surgery, such as bypass surgery, on all vessels of the heart, including lateral and posterior vessels. Pump and cannula systems are provided for supporting pulmonary and/or circulatory blood flow external of the heart during any beating heart or still heart surgical procedure, including value repair or replacement. The invention eliminates the use of cardiopulmonary bypass (CPB) machines in all heart surgery and utilizes the patient's lung(s) for providing oxygenated blood during heart surgery. The invention further provides stents adapted for protecting from vein, artery, atrium and/or ventricle collapse during beating heart bypass surgery.Type: GrantFiled: May 24, 2005Date of Patent: June 3, 2008Inventors: Walid Najib Aboul-Hosn, William Russell Kanz

Patent number: 7182727Abstract: A minimal intrusive cardiac support apparatus is disclosed which requires only one incision into a main blood vessel or heart chamber. The apparatus includes a pair of generally coaxial and slideably arranged cannulae (one inner and one outer) communicatively coupled to a blood pump for providing right-heart and/or left-heart cardiac support during cardiac surgery. Optional balloons may be mounted on the outside of the inner and outer conduits which can be selectively inflated to seal off the sides surrounding vessel or to deliver cooling fluid or medication to the surrounding tissue. Using the apparatus, a method of pumping blood through the body is also disclosed.Type: GrantFiled: February 11, 2005Date of Patent: February 27, 2007Inventor: Walid Najib Aboul-Hosn

Patent number: 6210133Abstract: A blood pump for use in CPB and other heart surgeries includes a reusable motor stator element which is enclosed in a disposable, sterile pump housing. The reusable, non-sterilized motor stator element is completely encased by the pump housing so that the motor stator can be reused without sterilization. The sterile housing allows the blood pump to be placed closed to the patient and within the sterile surgical field. The placement of the blood pump close to the heart during heart surgery greatly reduces the priming volume of the system thereby reducing the amount of saline or drugs which are introduced the patient's blood. The sterile housing may be evacuated to reduce the risk of emboli which may occur due to the failure of a seal.Type: GrantFiled: September 30, 1998Date of Patent: April 3, 2001Assignee: A-Med Systems, Inc.Inventors: Walid Najib Aboul-Hosn, Sedig Noor, William Russell Kanz, Michael Guidera, Robert G.

Patent number: 6210397Abstract: This invention relates to a sealing cannula device which can be easily and properly inserted while effectively sealing an incision made during a surgical or non-surgical process. The sealing cannula device includes a cannula sleeve having an external flange and tissue engaging threads. The screw threads on the external surface of the cannula sleeve allows the device to be easily screwed through an incision made in a body cavity wall or blood vessel until the tissue abuts against the flange. The vessel or body cavity wall is compressed between the flange and a flat surface formed by the helical thread. An effective compression seal is formed between the device and cavity or vessel wall which protects the puncture site from environmental contaminants. An axial through hole in the device provides vascular or body cavity access during surgical or non-surgical procedures.Type: GrantFiled: January 13, 1999Date of Patent: April 3, 2001Assignee: A-Med Systems, Inc.Inventors: Walid Najib Aboul-Hosn, William Russell Kanz, Roland W.

Patent number: 6152704Abstract: A blood pump for use in CPB and other heart surgeries includes a sterilizable blood pump removably attached to a turbine drive unit. An impeller within the fully enclosed and sterile blood pump moves the blood from the pump inlet to the pump outlet. The pump snaps onto the turbine drive unit and a magnetic coupling between the pump and the drive unit is used to transmit the rotation of a turbine shaft to the pump impeller. The turbine drive unit is preferably a sterilizable unit which may be placed directly in the sterile surgical field. The blood pump with turbine drive allows the blood pump to be placed close to the surgical site and minimizes the length of the tubing required for connecting the pump to the patient.Type: GrantFiled: September 30, 1998Date of Patent: November 28, 2000Assignee: A-Med Systems, Inc.Inventors: Walid Najib Aboul-Hosn, Kelly McCrystle, Desmond O'Connell
