Patent number: 8821529Abstract: A device for occluding a septal defect is provided. In general, the occluding device has a contracted state that allows the occluding device to be received within a delivery device for deployment to the site of the defect and an expanded state that is achieved when the occluding device is deployed from the delivery device. The occluding device has a proximal portion, which may be substantially circular, a distal portion, which may be substantially ovaloid, and a connecting portion extending between the two. The distal portion may define first and second outer parts at opposite ends of the major axis, which may be bent or curved. The configuration of the proximal and distal portions allow the occluding device to securely engage the septal wall and be kept in position at the septal defect without causing substantial interference with the functioning of adjacent heart structures.Type: GrantFiled: March 25, 2011Date of Patent: September 2, 2014Assignee: AGA Medical CorporationInventors: Ryan Douglas Kariniemi, Mathias C. Glimsdale, John Oslund, Derek Randall Wise

Patent number: 8814889Abstract: A cannula has a longitudinal base member having a first clamping end and a longitudinal arm member pivotally attached to the longitudinal base member and having a second clamping end, the cannula being in a closed position when the first and second clamping ends are brought together. A first clamp member is located at the first clamping end and has a first passage. A second clamp member is rotatably attached to the arm member at the second clamping end and has a second passage. The first and second passages form a combined passage when the clamp is in the closed position. The cannula may have a first locking member positioned on the arm member and a second locking member positioned on the base member. The first and second locking members interact with each other to lock the cannula in the closed position.Type: GrantFiled: July 10, 2012Date of Patent: August 26, 2014Assignee: Lifeline Scientific, Inc.Inventors: Christopher P.

Publication number: 20140222041Abstract: A surgical clip for a clip applier to ligate vessels. The clip contains two opposing external and internal legs connected in parallel by two external apex and one internal apex to form a Y-shape configuration. As a vessel is ligated and compressed between the two external legs, the vessel attempting to expand from its compressed position, applies outwardly lateral forces to the external legs causing them to rotate outwardly. In response, the two opposing internal legs rotate in an opposing directions to the external legs rotations to maintain the position of the clip over the compressed tubular vessel.Type: ApplicationFiled: February 3, 2014Publication date: August 7, 2014Inventor: Pavel Menn

Patent number: 8795221Abstract: A bypass device for influencing blood pressure, including an implant with a volumetric chamber, having a connector or connecting means for connecting the volumetric chamber to a natural cardiovascular system, and having an adaptor or adaptation means, by which a change in volume of a volume of the volumetric chamber is enabled or effected upon a pressure change in the cardiovascular system or in the volumetric chamber. According to this invention, a change in volume in a lower pressure range between 50 mmHg and a pressure threshold value amounting to at least 100 mmHg amounts to at most 10 cm3, and in an upper pressure range between the pressure threshold value and 150 mmHg amounts to at least 10 cm3. With the device according to this invention, high blood pressure can be reduced in a carefully directed way.Type: GrantFiled: November 5, 2010Date of Patent: August 5, 2014Assignee: E.S.
