摘要： An improved vascular dilation catheter comprises an involuted tubular structure including outer and inner tubular walls which extend the entire length of the catheter. The outer tubular wall is enlarged at a distal end of the catheter to form a dilation balloon, and extends back the remaining length of the flexible tube at a reduced diameter to define an annular lumen which is used to inflate the balloon. Alternatively, the outer tubular wall may conform to the exterior of the inner tubular wall and separate axial lumens may be provided for inflation. By providing means for heating inflation medium within the balloon, the catheter may be utilized for performing thermal ablation therapy.

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： The apparatus for combined mechanical/laser myocardial revascularization of a human heart includes: inserting a mechanical piercing device and an elongated flexible lasing apparatus into the chest cavity of a patient; mechanically auto-piercing, micro-tearing or spreading the epicardium of the heart; and then lasing from beneath the epicardium through the myocardium. The apparatus is guided to an area exterior to a ventricle of the patient's heart, and the distal end of the energy delivery device such as an optical fiber apparatus is placed internal to the exterior wall of the heart through an opening which has been created by mechanically piercing, micro-tearing or spreading the epicardium, so that the myocardium and not the epicardium is irradiated with laser energy to allow passage of said energy delivery device such as an optical fiber distal end or said laser energy into the left ventricular cavity without causing a laser irradiation of the epicardium which might be a cause of operative bleeding and for better allowing the sealing of the epicardium after the apparatus is removed. The apparatus includes a hand-held device controllable by the physician having a removable distal head portion with an auto-piercing mechanism and can use a vacuum source to provide a suction force at the head portion. The auto-piercing mechanism is implemented by various ways such as a spring-biased actuating member in the TMR hand-held device and an electro-mechanical operated piercing mechanism. The hand-held TMR device with handle assembly can also be controlled by a computer to provide auto- sequencing of the auto-piercing needle mechanism and the laser firing with auto-fiber advancement.

摘要： A laser surgery device for performing laser myocardial revascularization procedures on a human heart comprises a hand-held body portion with a forwardly extending probe member with an enlarged head end assembly including a piercing tip. A movable fiber bundle connected to a laser source extends through the body portion and the probe member with its distal tip at the head end assembly. A control button on the body portion enables the device to move the distal tip forwardly from the head end, and selectable stop members are provided on the body portion to provide different travel distances for the optical fiber bundle during a procedure. The body portion has a rotatable nose-piece with an internal ratchet mechanism which enables the device user to rotate the probe member and its head end to a selected optimum position before commencing a procedure. The head end assembly includes an easily replaceable piercing member in combination with a concave disk having a yieldable liner for cushioning the head assembly contact with the patient's heart. The device is used with a TMR procedure wherein the epicardium is initially pierced to provide access to the myocardium for the distal tip of the fiber bundle which then emits laser pulses as it is moved through the myocardium.

摘要： A minimally invasive surgical apparatus for providing access to the inside of a chamber of the heart for performing TMR on anterior and posterior walls therein. A unitary or a two piece trocar assembly is positioned through the chest wall. An obturator with a tissue piercing blade at one end is used to saw, pierce or otherwise cut a hole through the epicardium into and through myocardium. Once the trocar assembly extends into the heart chamber, a laser delivery device with deflection means is introduced into the chamber. Deflection or curvature of the end of the laser delivery device can be controlled by angulation control components, such that TMR channels can be created at various positions on the anterior and posterior walls of the chamber. Rotation control components for the fiber or other laser delivery devices will allow the surgeon to rotate the fiber once a predetermined deflection or curvature has been imparted to the distal end of the laser delivery device.

摘要： Improved methods and apparatuses related to laser-assisted transmyocardial revascularization, and more particularly, to improved methods and apparatuses for precisely positioning a fiber-optic or other waveguide adjacent the area or areas to be lased, including at positions adjacent the posterior epicardial and endocardial surfaces of the heart and at trans-septal positions within the chambers of the heart, thereby making possible the creation of channels in myocardial tissue at precisely the positions in the heart where ischemia or infarction or other have rendered such treatment desirable or necessary. These methods and apparatuses can be adapted for use in surgical applications throughout the human body or in animals for transmitting laser energy precisely, at predetermined positions and to predetermined depths. A catheter device for performing laser-assisted transmyocardial revascularization (TMR), the device particularly adapted for delivery of laser energy via a laser delivery device or manipulation of some other apparatus inside a body cavity or organ chamber where the depth of delivery of the laser energy is critical to the procedure, the device comprising an outer lumen and a depth stop, the depth stop having a deploying device, such that when the catheter device is placed adjacent tissue to be lased and the depth stop is deployed, the spatial reference of the position of the catheter device and the laser delivery device or other apparatus used in the catheter device is maintained in a predetermined position relative to the position of the distal end of the outer lumen. Deployment of the depth stop consists of inflating a balloon tip, or there may also be an inner lumen such that deployment comprises slightly retracting the inner lumen such that an expanding mechanism such as a braided basket or "moly bolt" device increases the diameter of the end of the catheter device, thereby providing a contacting surface for performing the surgical procedure, whether it be laser ablation, visualization, or other. A method of use is also described.

摘要： The present invention provides a retractor for providing surgical access through a passage in tissue, together with methods for its use and deployment. The retractor comprises an anchoring frame having an upper surface, a lower surface, and an opening therethrough which defines an axial axis. A flexible tensioning member is attached to the frame, and is extendable from the frame out of the body through the passage when the frame is positioned through the passage and into a body cavity. This tensioning member is selectively tensionable to spread the tissue radially outwardly from the axial axis. Hence, it is the tension imposed on the flexible liner which effects retraction of the tissue, rather than relying on the structural integrity of an artificial lumen.
