摘要： A computer-assisted medical device is configured and used to endoluminally navigate to a location in the gastrointestinal system and there treat certain body lumen wall areas while avoiding other body lumen wall areas. Embodiments ablate the inner mucosal layer and sub-mucosal nerve plexus of the stomach, duodenum and jejunum to effect treatment of insulin resistance and metabolic disorders, such as Type II diabetes (T2D), polycystic ovarian syndrome (PCOS), non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), congestive heart failure (CHF) and obstructive sleep apnea (OSA). Various sensors are used to assist a clinical operator to navigate from the mouth through the pyloric sphincter and into and through the duodenum and/or jejunum. Various sensors are used to map and identify portions of the duodenum and/or jejunum. Various lumen wall ablation devices and methods are described. Various post-treatment assessments are described.

摘要： The following describes various applications and uses for a controllably rigidizable flexible device or sheath. Such rigidizing mechanisms can allow for a transition between a rigid state and a flexible state of a sheath. Rigidization can be applied along an entire length of a flexible sheath or along select portions of the sheath, and the rigidization can be of varying stiffness. Rigidization can be user controlled or automatically controlled using computer processes.

摘要： A support apparatus for a medical device includes a first sleeve, a second sleeve, and a flexible contact member. The first sleeve is configured to be coupled to a first tool member of an end effector assembly that includes the first tool member, a second tool member, and a clevis, in which the first and second tool members are each rotatably coupled to the clevis such that second tool member can be moved relative to the first tool member between a first and a second orientation. The second sleeve is configured to be coupled to the second tool member. The flexible contact member is coupled to the first sleeve and the second sleeve, and is configured be moved between a collapsed configuration when the second tool member is in the first orientation and an expanded configuration when the second tool member is in the second orientation.

摘要： The systems and methods of the present disclosure are for use in a surgical procedure in which an elongate flexible medical device is utilized to create a model of patient anatomy using information from one or more of a localization sensor and an imaging sensor. Anatomical areas of interest may be identified and displayed on the model of patient anatomy, which may be used in performing a medical procedure on at least one of those areas of interest.

摘要： A medical device includes a clevis, a first blade, a second blade, and a tension member. The first and second blades are rotatably coupled to the clevis. The first blade includes a first coupling portion. The tension member is coupled to the first blade and applies a torque to the first blade to rotate the first blade about the clevis between a first, second, and third orientation. The second blade includes a second coupling portion. The second coupling portion is coupled to the first coupling portion such that A) the second blade remains in a fixed position relative to the clevis when the first blade is between the first and second orientation, and B) rotation of the first retractor blade between the second and third orientation transfers at least a portion of the torque to the second retractor blade causing rotation of the second blade about the clevis.
