    摘要： The present invention is directed to a balloon catheter, such as a dilatation catheter and a stent delivery catheter with improved stiffness transition and specifically with no sudden changes in stiffness along the catheter length. The balloon catheters of the present invention may be used alone or be mounted with a stent in. The balloon catheters of the present invention may be used in peripheral, coronary, or neurovascular applications. The present catheter has more than one portion with different bending stiffness values, each portion comprising of components that gradually transition the bending stiffness of that portion to an adjacent portion, thus reducing the differential in bending stiffness in moving from one region to another, when the catheter is used alone or in combination with a stent in a stent delivery system.

    摘要： A self-expanding filtration element is fitted to the distal end of a catheter while a sheath for constraining such element to a reduced diameter is mechanically manipulatable from the proximal end of the device. The entire device is maneuvered into position over a guide wire and deployed prior to treatment of the body lumen at an upstream location. After completion of the treatment procedure, the filtration element is collapsed and constrained within the sheath to retain any embolic material that has been captured and allow it to be safely removed from the vasculature. The device may be combined with a primary treatment modality and its low profile allows the constrained filtration element to be removed through a deployed stent.

    摘要： A method comprising (a) illuminating a blood vessel in a relatively low-light surgical field by inserting a subcutaneous light source into tissue near the blood vessel and to a first location in the tissue underlying the blood vessel, and causing emission of light from the subcutaneous light source while the subcutaneous light source is at the first location, so that light from the subcutaneous light source passes through the tissue near the blood vessel, toward an observer; (b) drawing a portion of the tissue near the blood vessel through an incision in the skin; and (c) illuminating the drawn portion of tissue by activating an external light source in a hands-free manner, thereby facilitating determining whether the drawn tissue is the blood vessel.

    摘要： Apparatus for advancing a vascular implant into a blood vessel. The apparatus comprises a first elongate member, the first elongate member having sufficient column strength to function as a pusher member; and a second elongate member, the second elongate member being thinner than the first elongate member and extending to a distal end located at a first point which is at or near a distal end of the first elongate member. The elongate members form an implant retaining portion while the distal end of the second elongate member is located at the first point. The implant retaining portion is located proximal of the first point. The implant retaining portion comprises a space located between the elongate members and configured for receiving an implant portion, with the first elongate member on one side of the space and the second elongate member on another side. The implant retaining portion further comprises a proximal side and a distal side which further circumscribe the space. The proximal and distal sides are effective to prevent an implant received in the retaining portion from moving out of engagement with the retaining portion as the first elongate member is moved distally and proximally. The implant retaining portion is removable by withdrawing the second elongate member in a proximal direction with respect to the first elongate member, thereby moving the distal end of the elongate member proximally beyond the former location of the implant retaining portion. Associated methods, and other apparatus and methods, are also disclosed.
