摘要： An apparatus for imaging a body structure within a body cavity includes a catheter including proximal and distal ends, an imaging element on the distal end, and an extension extending distally from the distal end for contacting a surface of a body cavity into which the catheter is introduced. The extension has a length to maintain the optical imaging element away from the surface. Optionally, a transparent member, e.g., an expandable balloon, may be attached to the distal end of the tubular member and the extension to isolate the imaging element from contact with fluid within the body cavity. During use, the catheter is inserted into a chamber of a beating heart, and the extension and/or balloon is placed against the wall of the chamber. Sufficient force is applied to stabilize the imaging element relative to the wall while the heart is beating.

摘要： Apparatus and methods are provided for providing access to a body lumen. The apparatus includes a tubular member including a proximal end, a distal end sized for insertion into a body lumen, and a lumen extending between the proximal and distal ends. A pushable stiffening member extends from the distal end of the tubular member, the elongate member terminating in a distal tip.

摘要： Apparatus, systems, and methods are provided for delivering stem cells or other agents to cardiac tissue surrounding a cardiac vessel or to tissue adjacent other body lumens. The apparatus includes an expandable member and a source of one or more agents communicating with a lumen extending between proximal and distal ends of the apparatus. The distal end of the apparatus is advanced through one or more body lumens until the distal end is disposed within or adjacent the target body lumen. The target body lumen is sealed, e.g., by expanding the expandable member, thereby isolating the target body lumen. One or more agents are delivered into the target body lumen with sufficient pressure to extravasate the one or more agents into tissue surrounding the target body lumen.

摘要： Apparatus and methods for locating morphological features within a body cavity using a catheter including proximal and distal ends, a transparent balloon carried on the distal end, and an optical imaging assembly carried on the distal end for imaging through the balloon. The balloon includes a channel extending therethrough to a lumen extending through the catheter. A guidewire or other localization member is received in the lumen that is extendable through the channel. During use, the catheter is inserted into a right atrium of a heart, and the balloon is expanded and placed against the wall of the heart to locate the coronary sinus. Sufficient force is applied to clear blood between the surface and the wall and clear the field of view of the imaging assembly. The catheter is manipulated to locate the coronary sinus, whereupon the localization member is advanced into the coronary sinus.

摘要： An apparatus for accessing a body lumen includes a tubular member including a proximal end, a distal end sized for introduction into a body lumen, and a passage extending along a steerable distal portion of the tubular member. The passage includes a first region extending substantially parallel to a center of modulus of the distal portion and a second region offset from the center of modulus. A steering element is disposed through the passage extending along the distal portion that includes a proximal end disposed adjacent the tubular member proximal end, and a distal end fixed to the tubular member distal end beyond the distal portion. A steering adjustment member is slidable within the passage for selectively directing a portion of the steering element between the first and second regions to vary the steerability of the distal portion.

摘要： Apparatus and methods provide distal protection while accessing blood vessels within a patient's vasculature. A flexible sheath and distal protection element, e.g., a balloon or filter, are carried by a stiffening member. The sheath is lubricious and has a relatively thin wall, thereby providing a collapsible/expandable guide for delivering fluids and/or instruments. The sheath is advanced into a blood vessel in a contracted condition, expanded to an enlarged condition to define a lumen, and the distal protection element is deployed within the vessel beyond the sheath. Fluids and/or instruments are introduced into the vessel via the sheath lumen, the distal protection element retaining the fluids and/or capturing emboli released by the instruments. Upon completing the procedure, the sheath, distal protection element, and stiffening member are removed from the vessel.

摘要： Apparatus and methods are provided for substantially continuously forming thin-walled sleeves that may be incorporated into tubular devices sized for introduction into a patient. In one embodiment, a pair of sheets including coated surfaces oriented towards one another are directed through a cutting apparatus to cut the sheets into multiple pairs of strips. The pairs of strips are bonded together to create a plurality of sleeves having lumens defined by the coated surfaces. In another embodiment, a sheet having a coated surface is fed through a cutting tool to separate the sheet into a plurality of strips, and the strips are formed into sleeves, e.g., by feeding the strips through a die or mandrel using a substantially continuous process. Optionally, the sleeves may be subsequently cut into individual tubular devices and/or further processed, e.g., by providing one or more layers around the sleeves to create catheters, sheaths, or other apparatus.
