摘要： A method and apparatus are provided for performing a balloon angioplasty procedure and for exchanging a guide wire and an intravascular catheter during the procedure. An intravascular balloon catheter includes an elongated shaft having a proximal portion adapted to extend outside the body of a patient during use, a distal portion adapted for connection to a dilation balloon and adapted for positioning intravascularly during use, and an inflation lumen extending therethrough in fluid flow communication with the balloon. In one aspect of the invention, an elongated guide lumen is connected to the catheter such that the guide lumen and catheter are movable relative to each other during use. A proximal portion of the guide lumen is adapted to extend outside the body of a patient during use, and a distal portion of the guide lumen is adapted to extend distally of the balloon during use. In another aspect of the invention, one or both of a guide wire and an intravascular device can be withdrawn from the guide lumen while the guide lumen remains substantially stationary. In yet another aspect of the invention, proximal and distal seal members are adapted to provide a substantially sealing fit around an intravascular device to inhibit the egress of fluid from the balloon.

摘要： Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together. If the device is left within the PFO track, the device is flattened from an expanded configuration to a flattened configuration, and the walls of the PFO track, adhering to the outer surface of the device, are pulled toward each other as the device flattens. The device may also include interior structure to hold the device in a flattened configuration.

摘要： An evacuation sheath assembly and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The evacuation sheath assembly includes an elongated tube defining an evacuation lumen having proximal and distal ends. A proximal sealing surface is provided on a proximal portion of the tube and is configured to form a seal with a lumen of a guided catheter. A distal sealing surface is provided on a distal portion of the tube and is configured to form a seal with a blood vessel. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. Prior to advancing a device across a stenosis to be treated, normal antegrade blood flow in the blood vessel proximate to the stenosis is stopped. While blood flow is stopped, the stenosis is treated. Retrograde blood flow is induced within the blood vessel to carry embolic material dislodged during treating into the evacuation sheath assembly.

摘要： An evacuation sheath assembly and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. A method of treating a lesion within a blood vessel, e.g., a coronary artery, includes advancing a sheath into the blood vessel, the sheath having a lumen extending to a port at a distal end of the sheath and further having an occlusive member within a distal region of the sheath. The occlusive member is then positioned within the blood vessel proximal to the lesion. Subsequently, the occlusive member is deployed, thereby stopping antegrade flow across the lesion. A contrast agent can then be infused through a port in the sheath. A dilation balloon is then advanced across the lesion. Suction is then applied to the lumen to induce retrograde flow across the lesion after dilating the lesion.

摘要： In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.
