摘要： An apparatus for passing a guidewire through a subcutaneous tissue tunnel to enable over-the wire insertion of a catheter through the tissue tunnel. The apparatus comprises an elongated member having a distal end portion having a tip configured to advance through the tissue tunnel and an opening extending longitudinally with respect to the apparatus and dimensioned to receive the guidewire. The guidewire is inserted through the opening to pass the guidewire through the tunnel to enable subsequent insertion of the catheter.

摘要： A surgical apparatus for removing deposits from an interior of a vessel comprising a rotatable shaft and a rotatable tip mounted to the rotatable shaft which is rotatable about its longitudinal axis upon rotation of the shaft to remove deposits from the interior of the vessel. The tip has a distal portion, a proximal portion and an intermediate portion between the distal and proximal portions. The intermediate portion is defined by a plurality of transverse cross-sectional areas, wherein each transverse cross-sectional area defines first and second axes substantially perpendicular to each other to define a width dimension along a first axis and a height dimension along the second axis. The height dimension is greater than the width dimension.

摘要： The present invention provides a valve configured for insertion on the proximal and distal sides of a heart valve annulus to replace the heart valve of a patient. The valve comprises a first substantially annular portion adapted to be positioned on a proximal side of the annulus of a patient and a second substantially annular portion adapted to be positioned on a distal side of the annulus of a patient, wherein at least one of the first and second substantially annular portions is movable towards the other portion to a clamped position to clamp around the annulus. The second portion has a flow restricting portion extending therefrom and is movable between a first position to permit the flow of blood and a second position to restrict the flow of blood. In one embodiment, the valve has a suture joining the first and second portions to draw the first and second portions into closer proximity and a cinch member to secure the suture to maintain the first and second portions in the clamped position. In another embodiment, the first and second portions are connected by a first segment which biases the first and second portions toward the clamped position.
