Abstract: Methods of performing surgical operations and associated devices are disclosed. An example method may include locating a first position on a first surface of a biological tissue; locating a second position on a second opposing surface of the biological tissue, the second position corresponding to the first position; and marking the second position on the second surface. The second surface may be generally opposite the first surface. An example method may include, after marking the second position, performing a therapeutic procedure on the biological tissue in the vicinity of the second position.

Abstract: Medical devices and instruments, particularly appliers that may be used to apply occlusion devices such as occlusion clips on anatomical structures, are disclosed. Some example clip appliers may include an activation lever configured to open and close an occlusion clip releasably mounted in an end effector. Some example clip appliers may include a deployment trigger configured to release the occlusion clip from the end effector. Some example clip appliers may include a shaft extending between a handle and the end effector that is rotatable and/or bendable.

Abstract: Apparatus and systems include an electrosurgical instrument with a unique jaw configuration and gripping surfaces that allow tangential gripping and ablation of tissue in a minimally invasive procedure. The electrosurgical instrument can include a shaft and hinge coupling the shaft to first and second jaws. The first jaw can be an anchor for the second jaw. The jaws can have respective first portions and second portions offset at an angle from the first portions. Each jaw can also include electrodes on their inner surfaces facing the other jaw. Each jaw can also include textured gripping surfaces. The gripping surfaces can be included on at least a portion of the base of each jaw, as well as on at least a portion of the inner surfaces of the jaws.
