摘要： An apparatus is disclosed for attaching a counter pulsation device (CPD) to a blood vessel in a human or animal subject, the apparatus including: an interposition graft having a first end configured to be attached to the blood vessel, a second end, and an interior passage providing fluid connection between the first end and the second end; and a pump graft having first end attached to the second end of the interposition graft, a second end configured to be attached to the CPD, and an interior passage providing fluid connection between the first end and the second end. In some embodiments, the interior passage of the interposition graft includes a rough surface configured to promote biological growth on the surface, and the interior passage of the pump graft includes a smooth surface configured to inhibit biological growth on the surface.

摘要： A fluid vessel pump can include multiple chambers that operate in a reciprocal manner to pump fluid in a vessel. For example, the vessel pump can include a first expandable chamber structure configured to be implanted within a first fluid vessel and a second expandable chamber structure configured to be implanted within a second fluid vessel that is adjacent to the first fluid vessel. The first expandable chamber structure can be in fluid communication with the second expandable chamber structure. Compression of the first expandable chamber structure can cause expansion of the second expandable chamber structure.

摘要： A method of operating a counterpulsation device (CPD) in a human or animal subject is disclosed, the method including: receiving a heart beat signal indicative of the heart beat of the subject; providing counterpulsation therapy by controlling the pressure supplied to a CPD drive line in pneumatic communication with the CPD to cause the CPD to alternately fill with blood and eject blood with a timing that is determined at least in part based on the heart beat signal; while providing counterpulsation therapy, receiving a CPD drive line pressure signal indicative of the pressure in the CPD drive line; and adjusting the pressure supplied to the drive line based at least in part on the drive line pressure signal.

摘要： - Système de fixation d'une valve cardiaque sur une prothèse cardiaque et prothèse cardiaque pourvue d'un tel système de fixation.
- Le système (1) a pour fonction de fixer une valve cardiaque (3) sur une prothèse cardiaque (2) destinée à être implantée dans la cavité péricardique d'un patient et à remplacer les ventricules gauche et droit naturels du patient, ce système (1) comportant une bague mâle (10) pourvue de picots (11) et une pièce coopérante (12) pourvue d'ouvertures (13), la bague mâle (10) ou la pièce coopérante (12) étant destinée à être solidarisée de la prothèse cardiaque (2), les picots (11) et les ouvertures (13) étant configurées pour que lesdits picots (11) traversent une collerette (9) de la valve cardiaque (3) et pénètrent dans les ouvertures (13) dans une position de fixation, ce système (1) pouvant être utilisé pour fixer des valves cardiaques (3) de réalisations variées.
