    摘要: Devices, systems, methods, and kits for treating the tissue structures of the ear make use of a guide structure that can mechanically register a treatment probe with a target region of a target tissue, the guide structure being fittingly received in an auditory canal and often comprising a conformable body such as a compressible foam, or the like. The guide structure may include an articulating mechanism for selectively orienting the treatment probe toward the target region of, for example, a tympanic membrane. The guide structure may also support a videoscopic image capture device, illumination transmitting optical fibers, an aiming beam transmitter, and the like. Such structures facilitate myringotomy, tympanostomy tube placement, and the like, under local anesthesia in a doctor's office.

    摘要: The methods and apparatus for lead placement on a surface of the heart are employed using an elongated body having proximal and distal end portions. The body defines a lead receiving passageway extending between a proximal inlet and a distal outlet for receiving a lead therethrough for contact with the heart surface. The elongated body is adapted for insertion between a pericardium and an epicardial surface. At least a portion of the body may have a non-circular cross-sectional shape adapted to retain the body orientation between the pericardium and the epicardial surface.

    摘要: The invention provides methods and devices for delivering low level radiation to inhibit neointimal hyperplasia following angioplasty or other intravascular procedures. In an exemplary method, a balloon is inflated within a stenosed region of a blood vessel to produce a treated region. The balloon is then deflated and a radioactive source within a sleeve is aligned over the deflated balloon. The balloon is again inflated at the treated region to engage the sleeve having the radioactive source against the blood vessel within the treated region for from 1 to 40 minutes to deliver a sufficient dosage of radiation to inhibit neointimal hyperplasia.

    摘要: An intravascular catheter provides means for infusing an agent into a treatment site in a body lumen and means for deploying the infusing means adjacent the treatment site which operate independently of one another. In a first embodiment, a flexible catheter body has an expansion member attached to its distal end in communication with an inflation passage, and an infusion array disposed about the expansion member in communication with one or more delivery passages. In a second embodiment, the infusion array is a separate component and slidably received over the expansion member, which may be a balloon dilatation catheter. In both embodiments, the infusion array includes a plurality of delivery conduits having laterally oriented orifices. The delivery conduits may be extended radially from the catheter body to contact a treatment site by expanding the expansion member with an inflation fluid. An agent may be introduced into the delivery passages and infused into the treatment site through orifices in the delivery conduits. The expansion member may be expanded for dilatation of the lumen before, during, or after infusion.

    摘要: A catheter sleeve includes a radially expansible distal region having a plurality of axial blood perfusion lumens or channels formed thereon. The catheter sleeve may be introduced over a conventional angioplasty balloon catheter with the expansible region lying over the balloon. When the balloon of the angioplasty catheter is expanded, the perfusion lumens will provide a flow path for blood around the expanded balloon. Optionally, the catheter sleeve may further include drug infusion lumens over the radially expansible region. In this way, drugs can be delivered over prolonged periods while the underlying angioplasty balloon is inflated and blood flows through the lumens or channels to perfuse the distal myocardium.

    摘要: Methods and apparatus for closing a left atrial appendage are described. The methods rely on introducing a closure tool from a location beneath the rib cage, over an epicardial surface, and to the exterior of the left atrial appendage. The closure device may then be used to close the left atrial appendage, preferably at its base, by any one of a variety of techniques. A specific technique using graspers and a closing loop is illustrated.
