摘要： Apparatus and methods are provided for treating a lesion within a body lumen using a catheter including a balloon on its distal end that includes a plurality of raised structures that extend outwardly from the balloon membrane. In one embodiment, the raised structures are provided in pairs that are spaced apart from one another about the circumference of the balloon, and each pair includes two raised structures that are spaced relatively closely together compared to the distance the two raised structures are spaced apart from adjacent pairs. Optionally, the membrane between the two raised structures of each pair may be relatively thinner than the membrane between spaced apart pairs such that the distance between the raised structures in each pair increases as the balloon is expanded within a lesion.

摘要： Embodiments provide methods and systems for treating aneurysms using filling structures filled with a curable medium. An embodiment of a method comprises positioning at least one double-walled filling structure across the aneurysm and filling the structure(s) with a filling medium so that an outer wall conforms to the inside of the aneurysm and an inner wall forms a generally tubular lumen to provide for blood flow. The lumen is supported with a balloon or other expandable device while and/or after filling. The pressure within the structure and/or in the space between an external wall of the structure and the aneurysm wall is monitored and a flow of the medium into the structure is controlled responsive to the pressure. The pressure can also be used to determine a filling endpoint. The medium is hardened while the lumen remains supported by the balloon. The balloon is then removed after the medium hardens.

摘要： Apparatus and methods are provided for treating a lesion within a body lumen using a catheter including a balloon on its distal end and an abrasive distal tip extending distally beyond the balloon. The distal tip may terminate in a sharpened tip for penetrating occlusive material, e.g., a beveled tip, and includes abrasive material on an outer surface thereof, e.g., abrasive grit, cutting elements, and the like, for abrading occlusive material adjacent the distal tip. The abrasive material may be arranged in a predetermined pattern, e.g., an axial, circumferential, or helical pattern, to facilitate abrading occlusive material. The distal tip may have a substantially uniform diameter or tapered shape along its length.

摘要： Enhanced dual purpose systems enable dilating of at least a lesion within a blood vessel and providing an anti-proliferative medicament in a non-attached form directly into the lumen of the vessel. Likewise provided is the ability to stop blood flow to prevent wash-out of the medicament during dwell time within the body lumen, and the ability to remove the medicament after the dwell time of the device to prevent unwanted exposure of the same within the body.

摘要： An apparatus is provided that is operable in different modes to perform various functions for treating a body lumen. The apparatus includes a shaft including a proximal end, a distal end, a lumen extending therebetween, and a balloon on the distal end having an interior communicating with the lumen. The apparatus includes a valve on the distal end that selectively opens or closes an outlet communicating with the lumen. With the valve open, fluid introduced into the lumen exits the outlet into a body lumen. With the valve closed, fluid introduced into the lumen expands the balloon. The apparatus also includes an actuator for axially compressing the balloon, and a helical member extends between ends of the balloon interior that expands the balloon from a contracted condition to an expanded helical shape when the actuator is activated.

摘要： Apparatus and methods are provided for delivering fluid into a body lumen during a medical procedure. A distal end of an apparatus may be introduced into a body lumen, and a valve on the distal end may be opened to deliver fluid through a first lumen into the body lumen, e.g., contrast and/or other diagnostic or therapeutic agents. The valve may be closed, and a procedure may be performed within the body lumen, e.g., using a treatment element carried on the distal end. For example, the treatment element may include a balloon that may be inflated when fluid is delivered through the first lumen with the valve closed. Optionally, a prosthesis, energy source, drug platform, and the like may be carried by the balloon for treating the body lumen. In various embodiments, the valve may be located proximal or distal to the treatment element.

摘要： Aneurysms are treated by placing a scaffold across an aneurysmal sac to provide a blood flow lumen therethrough. An aneurysmal space surrounding the scaffold is filled with one or more expandable structures which are simultaneously or sequentially expanded to fill the aneurysmal space and reduce the risk of endoluminal leaks and scaffold migration. The expandable structures are typically inflatable and delivered by delivery catheter, optionally with an inflation tube or structure attached to the expandable structure.
