Abstract: Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. 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. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.

Abstract: Apparatus and methods for the treatment of atrial fibrillation are described herein where tissue to be ablated may be monitored under direct visualization for tissue parameters (e.g., temperature and impedance) prior to, during, or after ablation. The 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 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.

Abstract: Systems, devices and methods for endoscopic procedures are provided involving accessing and manipulating tissues beyond the capabilities of traditional endoscopic instruments. Embodiments of the systems include an elongated main body (10) which has one or more independently shape-lockable sections (90, 92, 93) and a variety of instruments which are either built in to the main body or advanceable through lumens (24, 26, 58) which extend through the main body (10). Such instruments may include scopes, suction instruments, aspiration instruments, tool arms, plicators, needles, graspers, and cutters, to name a few. The ability to steer and shape-lock specific sections (90, 92, 93) of the main body (10) enables access to target locations which are typically challenging to reach and provides a stabilized platform to perform a desired procedure at the target location.

Abstract: Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point and moving the first tissue contact point from a position initially distal to, or in line with, a second tissue contact point to a position proximal of the second contact point, thereby forming the tissue fold, and extending an anchor assembly through the tissue fold from a vicinity of the second tissue contact point. Adjustable anchor assemblies; as well as anchor delivery systems, shape-lockable guides and methods for endoluminally performing medical procedures, such as gastric reduction, treatment of gastroesophageal reflux disease, resection of lesions, and treatment of bleeding sites; are also provided.

Abstract: Needle assemblies for tissue manipulation are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. A needle deployment assembly is deployable through the tissue manipulation assembly via a handle assembly, through the tubular member, and into or through tissue. An elongate pusher is translationally disposed within a sheath of the needle deployment assembly and can be urged distally for deploying an anchor assembly from the sheath distal end. The anchor assembly is positioned distally of the pusher within the sheath.
