摘要： Methods and apparatus of embodiments of the invention are adapted to treat tissue inside a patient's body. Aspects of the invention can be used in a wide variety of applications, but certain embodiments provide minimally invasive alternatives for treating atrial fibrillation by delivering a tissue-damaging agent to selected areas of the heart. One exemplary embodiment of the invention provides a method of treating cardiac arrhythmia. This method includes positioning a distal tissue-contacting portion of a body in surface contact with a tissue surface of cardiac tissue; detecting the surface contact between the tissue-contacting portion and the tissue surface; and thereafter, injecting a tissue-ablating agent into the cardiac tissue through the tissue-contacting portion of the body.

摘要： The invention described herein provides for methods and devices for treating tissues, and in particular, ischemic heart tissue. Preferred devices includes tools integrating both injury and treatment effectors in a single unit. An optional third effector provides an effector for marking locations on a tissue surface that have been visited by the device. Methods are provided in which a target tissue is identified, injury sites are created at known locations, and therapeutic-substance is infused at known locations different than the injury sites.

摘要： A method and apparatus for treating an atherosclerotic target region of a coronary vessel in a patient are disclosed. The method includes delivering to the patient, a photoatherolytic compound, to cause accumulation of the compound in the target region, accessing the target region intraluminally with a guidewire, and advancing over the guidewire, a catheter having (i) a proximal main-body sleeve, (ii) a flexible, non-inflatable, translucent distal-end sleeve joined to the main-body sleeve at a catheter juncture, and (iii) an inner lumen extending through the two sleeves, said advancing being effective to position the catheter's distal-end sleeve within the target region. The guidewire is then removed and replaced by a fiber-optic bundle having a light-diffusing tip, until said tip is positioned adjacent the catheter juncture. After injecting a light-transmissive fluid through the catheter into the catheter's distal-end sleeve, the target vessel region is irradiated by passing a laser light beam through the fiber optic bundle.

摘要： Various methods and devices for treating a patient who has lost, or is at risk of losing cardiac function by cardiac ischemia are disclosed. Treatment includes first imaging a patient's heart, or a portion thereof, to identify underperfused regions of cardiac muscle, and a source of oxygenated blood that is proximate to the underperfused region. Between the underperfused regions and the oxygenated blood source, a target area is selected where thermal or mechanical injury is introduced, and optionally reintroduced, to convert initial capillary blush, resulting from the injury.

摘要： A non-deforming deflectable multi-lumen catheter with an outer jacket having a deflectable distal end portion, an eccentric pull wire lumen, coil and shim embedded therein. The deflectable distal portion optionally having one or more transaxial notches in the external surface of the outer jacket. A functional device is disposed within the lumen of an inner tube substantially coaxial with the outer jacket of the catheter. The distal tip of the functional device egressible from the distal tip of the catheter, and upon deflection, automatically aligns with the distal tip of the catheter and functional device.
