摘要： Apparatus and methods for optimizing anchoring force are described herein. In the securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchor (10) having expandable arms (12) configured to minimize contact area between the anchor (10) and tissue. When the anchor (10) is in its expanded configuration, a load is applied to the anchor (10) until it is optimally configured to accommodate a range of deflection while the anchor (10) itself exerts a substantially constant force against the tissue. Various devices e.g., stops, spring member, fuses, strain gauges, etc., can be used to indicate when the anchor (10) has been deflected to a predetermined level within the optimal rang. Moreover, other factors to affect the anchor (10) characteristics include, e.g., varying the number of arms (12) or struts (12) of the anchor (10), positioning of the arms (12), configuration of the arms (12), the length of the collars (14, 16), etc.

摘要： Apparatus and methods for endoluminal advancement are described herein. A shape-lockable tissue anchoring assembly generally has an elongate body, a handle assembly, and an anchoring assembly positioned at or proximal to a distal tip of the elongate body. A distal portion of the elongate body may optionally be steerable or curvable. The anchoring assembly may include various expandable (30) or projecting anchoring features to contact and retain tissue relative to the elongate body such that pleated tissue is temporarily immobile relative to the elongate body. This anchoring can be actuated simultaneously with or independently from shape-locking of elongate body. The anchoring assembly can be actuated simultaneously with the shape-locking of the elongate body. Alternatively, the steerable distal portion of the elongate body can be angled against the pleated tissue to retain it while the endoscope is advanced relative to the pleated tissue.

摘要： 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.

摘要： Flexible shaft systems having interchangeable end effectors are described herein. A shaft with a flexibility sufficient to allow advancement through a lumen of an endoscopic device has an interface at its distal end for engaging a removable end effector tool. The shaft and end effector tool are configured to enable endoluminal deployment through a patient, e.g., through the esophagus and into the stomach. The removable end effector tool may comprise any number of different tools, such as graspers, forceps, scissors, snares, needles, etc., each being interchangeable upon the flexible shaft distal end. Once a procedure is done within the patient, the flexible shaft may be withdrawn and another distal end effector tool may be interchanged. The new end effector tool and flexible shaft can then be reintroduced into the patient.

摘要： Tissue manipulation and securement systems are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member and has a lower jaw member and an upper jaw member pivotably coupled to the lower jaw member. A reconfigurable launch tube is also pivotably coupled to the upper jaw member and is used to urge the jaw members from a low-profile configuration to an open configuration for receiving tissue. The tissue manipulation assembly may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly.

摘要： Apparatus and methods for manipulating and securing tissue 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. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.
