    摘要： The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

    摘要： A medical device includes a catheter shaft extending along a longitudinal axis and having a shaft lumen. A balloon includes a proximal balloon end coupled to the catheter shaft, an interior in fluid communication with the shaft lumen, and a distal balloon end. A lead wire extends from a proximal wire end through the shaft lumen and the interior to a distal wire end. The lead wire includes a stepped portion between a proximal wire surface and a distal wire surface. The distal balloon end is axially fixed to the proximal wire surface. The proximal wire surface is narrower than the distal wire surface. Other embodiments are described and claimed.

    摘要： A flexible drive shaft assembly is provided for an intravascular medical device, for example and without limitation, a blood pump, a rotational atherectomy device, or a rotational thrombectomy device. The blood pump embodiment provides an electric motor and a rotational impeller, with a rotational drive shaft disposed therebetween and configured to rotationally drive the impeller. The drive shaft is moved from an undeformed length to a deformed length when connected between the electric motor and the rotational impeller to provide a biasing force on the rotational impeller in the proximal direction to maintain the impeller in a desired axial or linear location. In other embodiments, drive shaft comprises a proximal section with a length and a spring constant and a distal section of relatively longer length and a relatively higher spring constant. In other embodiments, hypotube(s) and/or support mandrel(s) may be provided.

    摘要： Devices, methods and systems are described that enable achieving a working diameter that is greater than a resting diameter and to stimulate fluid circulation during high-speed rotation. The drag coefficient of the drive shaft is increased and, in some embodiments, the mass is increased. Among other advantages, the resulting drive shaft with an eccentric element integrated with and/or attached thereto will achieve orbital motion at a rotational speed that is less the rotational speed required to achieve orbital motion without the increased drag coefficient. The concomitant increase in fluid flow and/or fluid stirring at a comparatively lower rotational speed is a further advantage. These characteristics may allow, therefore, a smaller diameter abrasive element to be used which is advantageous in small and/or highly tortuous vessels.
