    摘要: Methods and apparatus for thoracoscopic defibrillation of a patient's heart. The technique involves introducing a first electrode (10) through a percutaneous intercostal penetration, positioning the first electrode against the heart surface (H) and positioning a second electrode (10') against the patient's body. A voltage is then applied through the percutaneous intercostal penetration to the first electrode and to a second electrode to deliver electrical energy to the first electrode, through at least a portion of the patient's heart, and to the second electrode. The electrical energy applies an electric charge to the patient's heart to defibrillate the heart muscle or restart the heart during, for example, cardiac procedures that involve arresting the heart.

    摘要: An atherectomy catheter is provided for excising and imaging material in a body lumen. In one embodiment, the catheter comprises a catheter body, a cutting blade, and an imaging device. The cutting blade is mounted on the catheter body and configured to move between a first position and a second position relative to an aperture or cutting window. When the cutting blade is in the second position, the blade substantially closes the aperture on the catheter body. The imaging device which is mounted on or otherwise coupled to the cutting blade is configured to be in an imaging position when the cutting blade substantially closes the aperture or cutter window. This allows the imaging device to survey material within the cutting zone of the atherectomy catheter. By allowing the imaging device to view materials within this cutting zone, material may be imaged and then removed from the body lumen without having to reposition the catheter between each step.

    摘要: Devices and methods are provided for controlling and indicating the deployed length of an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. Devices for controlling the length of the interventional element include gear driven actuators, motors, and other mechanisms. Devices for indicating length of an interventional element to the user include sensors, detents, visual displays and other mechanisms providing visual, audible, and tangible indications of length to the user. The control and indication devices preferably work in tandem to enable highly precise adjustment of interventional element length.

    摘要: The method for performing an arthroscopic procedure on a joint using surgical navigation. A 3-D virtual model of the anatomy is created from a scan of the anatomy. The 3-D virtual model is then used to reproduce motion of the joint and plan the arthroscopic procedure. The 3-D virtual model is placed into registration with the real-world anatomy, so that a virtual image generated by the 3-D virtual model may be placed into registration with an arthroscopic image of the real-world anatomy. Preferably, arthroscopic registration markers, positioned prior to scanning, are used to place the 3-D virtual model in registration with the real-world anatomy. The arthroscopic registration markers may be placed either percutaneously or arthroscopically. At the conclusion of the procedure, the registration markers may be left in place, removed arthroscopically or allowed to biodegrade.

    摘要: The present invention provides a retractor for providing surgical access through a passage in a patient's body, together with a delivery device for positioning the retractor in the patient's body. 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. The retractor is held by the delivery device in a collapsed orientation for placement in the patient's body. The delivery device is released from the retractor to allow the retractor to assume an expanded orientation in the patient's body. This tensioning member is selectively tensionable to spread the tissue radially outwardly from the axial axis.
