摘要： Coronary sinus cannulation apparatus and methods relating to tissue visualization catheters that can locate and/or cannulate a morphological feature within a body lumen, such as the coronary sinus, are described. Such devices can also perform a variety of therapeutic tissue treatments under direct in vivo visualization thereafter. Moreover, such apparatus and methods may also be utilized with guidewires to facilitate delivery into the coronary sinus to eliminate repositioning of the device and/or repeating an entire sequence of operations, consequently improving procedure effectiveness and reducing procedure time.

摘要： Tissue visualization device and method variations are described herein where an imaging hood is temporarily sealed against a region of tissue to be treated while under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. 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 is pumped into the hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element. Temporary sealing against the tissue can be achieved in a number of ways such as circumferential balloons inflatable within the hood or other sealing techniques. A field of view of the imaging element can be expanded by inflating the balloon beyond the imaging hood.

摘要： The attenuation or isolation of environmental parameters on a gastric lumen is described herein. Once tissue plications are formed into a gastric lumen or sleeve within a stomach, the newly formed lumen is subjected to a multitude of fluctuating stresses or pressure from food or fluids passing therethrough, from naturally-occurring contractions, and/or from changes in pH levels from caustic stomach acids and hormones. The tissue interface between these plications can be isolated from such environmental fluctuations, or the fluctuations can be attenuated, by a number of methods. One example is to place a gastric stent or sleeve within the newly formed lumen. Another example is to utilize multiple rows of anchors, clips, or sutures along the interface. Alternatively, bio-adhesives can be dispensed to buttress the tissue interface. In another variation, the tissue can be approximated in different configurations which effectively reduce or isolate the adhered tissue region.
摘要翻译：本文描述了在胃腔上的环境参数的衰减或分离。一旦组织消融在胃内形成胃腔或套管，则新形成的内腔经受来自通过其的食物或液体的多种波动的压力或压力，从天然存在的收缩和/或pH水平的变化从苛性胃酸和激素。可以通过多种方法将这些斑点之间的组织界面与这种环境波动隔离，或者波动可以减弱。一个例子是将胃支架或套管放置在新形成的内腔内。另一个例子是沿着界面使用多行锚，剪辑或缝线。或者，可以分配生物粘合剂以支撑组织界面。在另一个实施方式中，可以以有效地减少或隔离粘附的组织区域的不同配置来近似组织。

摘要： Apparatus and methods are provided for mapping out endoluminal gastrointestinal surgery, including endoluminal gastric reduction. Mapping is achieved by locally marking the interior of the gastrointestinal lumen at specified locations. In some variations, mucosectomy and/or mucosal ablation are performed to map out endoluminal GI surgery, to facilitate direct endoluminal engagement of underlying muscularis tissue and/or to initiate a wound healing response. Specialized apparatus may be provided to achieve desired spacing and/or positioning of tissue markings, as well as to actually form the markings. Methods of using apparatus of the present invention are provided.

摘要： Axial visualization systems which utilize axially aligned imaging instruments for visualizing through an imaging hood purged of blood via a transparent fluid are described where an imaging element extending from a support shaft may be aligned within a working lumen defined through a deployment catheter. The imaging element may be positioned distal to the hood in its collapsed state and within the hood in its expanded state. The imaging element may be configured to seat itself securely within the catheter or to angle itself to adjust the viewing angle. Additionally, a disposable visualization sheath having a transparent lens may also be utilized to house an imaging instrument therein.
