摘要: A trans-septal guide catheter for providing access through the septum separating a first heart chamber from a second heart chamber that includes an elongated guide catheter body extending between guide catheter proximal and distal ends. A distal segment of the guide catheter is adapted to be inserted through the septum to locate the distal segment of the guide catheter within one of the first heart chamber and the second heart chamber. The catheter body encloses a guide catheter lumen adapted to provide access into the one of the first heart chamber and the second heart chamber through a guide catheter lumen proximal end opening and a guide catheter lumen distal end opening. A retention mechanism engages the septum and maintains the distal segment of the guide catheter extending into the one of the first heart chamber and the second heart chamber.

摘要: Device and method for sub-xiphoid ablation of patient tissue. A sub-xiphoid access clamp has a handle, an elongate neck coupled to the handle and first and second opposing jaws. The first and second opposing jaws have first and second opposing relief segments being generally co-planar and concave with respect to one another to form a void therebetween, and first and second opposing elongate ablation elements positioned along the first and second opposing jaws and distal of the first and second opposing relief segments relative to the handle. The first and second opposing jaws are articulate between a closed position and an open position to admit, at least in part, a second portion of tissue of the patient within the void created by the first and second opposing relief segments while the first portion of tissue is positioned between the first and second ablation elements in the closed position.

摘要: An instrument including an elongated shaft and a non-conductive handle is disclosed. The shaft defines a proximal section and a distal section. The distal section forms an electrically conductive tip. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. The instrument is useful for epicardial pacing and/or mapping of the heart for temporary pacing on a beating heart, for optimizing the placement of ventricular leads for the treatment of patients with congestive heart failure and ventricular dysynchrony and/or for use in surgical ablation procedures.

摘要: Methods for delivering precise amounts of fluid into cardiac tissue for the purpose of facilitating ablation of the tissue along a desired lesion line. One method injects fluid through a hollow needle. The injected fluid can be a highly conductive fluid injected in conjunction with radiofrequency ablation to create an ablative virtual electrode. The injected conductive fluid can provide deeper and narrower conduction paths and resulting lesions. Radiofrequency ablation can be performed at the same time as the fluid injection, using the injection device as an electrode, or subsequent to the fluid injection, using a separate device. In some methods, the injected fluid is a protective fluid, injected to protect tissue adjacent to the desired lesion line. Fluid delivery can be endocardial, epicardial, and epicardial on a beating heart. The present methods find one use in performing maze procedures to treat atrial fibrillation.

摘要: A catheter assembly and method for treatment of cardiac arrhythmia, for example, atrial fibrillation, by electrically isolating a vessel, such as a pulmonary vein, from a chamber, such as the left atrium. The catheter assembly includes a catheter body and at least one electrode. The catheter body includes a proximal portion, an intermediate portion and a distal portion. The intermediate portion extends from the proximal portion and defines a longitudinal axis. The distal portion extends from the intermediate portion and forms a substantially closed loop transverse to the longitudinal axis. The at least one electrode is disposed along the loop. With this configuration, the loop is axially directed into contact with the chamber wall about the vessel ostium. Upon energization, the electrode ablates a continuous lesion pattern about the vessel ostium, thereby electrically isolating the vessel from the chamber.

摘要: A method and system for ablating tissue to provide a desired set of lesions. The system includes an ablation apparatus having an elongated shapeable section carrying a mechanism such as an electrode for applying ablation energy along the shapeable section. The shapeable section includes a member of shape memory material having a memorized configuration. The shapeable section is shaped manually or using fixtures to display a configuration corresponding to one of the desired lesions and is then employed to create the desired lesion. Thereafter the shapeable section is heated to cause it to resume its memorized configuration. Shaping, heating and ablating to create lesions are continued as necessary provide the desired set of lesions. In some embodiments of the invention, heating may be accomplished using heating elements built into the shapeable section.
