    摘要： A method of inhibiting tissue migration comprises positioning an open area of a hood against or adjacent to a tissue region. The method also comprises displacing an opaque fluid with a transparent fluid from the open area. The method includes engaging a portion of the tissue region within the open area via an end effector advanced through the open area and which grasps onto the portion. The end effector includes a tapered section, tapered along its entire length, through which a lumen extends. The tapered section includes threads extending from a surface of the tapered section in a direction orthogonal to the longitudinal axis. The tissue region is pierced while displacing the opaque fluid with the transparent fluid through the distal opening of the hood and while maintaining engagement of the portion of the tissue region such that distal movement of the tissue is inhibited.

    摘要： Methods and apparatus for intraluminally or transluminally closing a left atrial appendage while under direct visualization are described herein. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for performing any number of procedures on the tissue for accessing and closing the left atrial appendage.

    摘要： Transmural subsurface interrogation and ablation apparatus and methods are described where tissue to be ablated is monitored while under direct visualization for tissue parameters (e.g., temperature and impedance) prior to, during, or after ablation. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An ablation probe and one or more interrogation needles having sensors are advanced into the tissue to be ablated and monitored. Alternatively, a combined ablation and interrogation probe may be used.

    摘要： Methods and apparatus for performing malabsorptive bypass procedures within a patient's gastrointestinal lumen are described comprising, for example, gastroenterostomy procedures that are preferably performed in an endoscopic or laparoscopic fashion. Anastomosis between the patient's stomach and intestine allows food to bypass at least a portion of the patient's stomach and/or intestine, thereby providing a malabsorptive region. The malabsorptive procedure may be accompanied by additional procedures, for example, pyloric occlusion, pyloroplasty, gastroplasty, gastric tissue destruction and/or intestinal pleating.

    摘要： Methods and apparatus for creating a working space within a patient's stomach are described. The working space is created by internally spreading or pushing the walls of the stomach apart. Advantageously, such spreading is achieved without pressurizing the patient's stomach, i.e. without injecting a pressurized gas or other fluid directly into the stomach. Diagnostic or therapeutic instruments may be deployed within the working space. It is expected that spreading the walls without pressurizing the stomach will facilitate engagement and/or manipulation of the stomach wall for, e.g., endoluminal treatment of obesity.
