Abstract: A system for delivering a replacement heart valve implant may include the implant including an expandable framework and leaflets coupled to the framework, and a delivery device including a handle and an elongate catheter extending from the handle. The catheter includes an outer sheath and an inner shaft movably disposed within the outer sheath. The implant is releasably coupled to the inner shaft. The inner shaft includes an orientation lumen extending longitudinally within the inner shaft, the orientation lumen being offset from a central guidewire lumen of the inner shaft. The delivery device includes an orientation mandrel disposed within the orientation lumen, the orientation mandrel extending distally from the handle to a distal end proximate a closed distal end of the orientation lumen. The orientation mandrel is operably coupled to an orientation mechanism of the handle configured to apply compressive force or tensile force to the orientation mandrel.

Abstract: The present disclosure includes elongate members for positioning medical devices at a target site within a body lumen. In various embodiments, the elongate member may include one or more articulation joints for maneuvering, one or more transducers for localizing, and one or more lumens for delivering instruments to the target site. Some embodiments are particularly directed to a medical device that guides an operator to a target site, confirms the location of the target site, and enables a biopsy to be taken from and/or a therapy to be delivered to the target site. For example, a position tracking sensor may be utilized to guide the medical device to the target site, a phased array sensor may be utilized to confirming proper positioning at the target site, and a biopsy needle inserted through a lumen may be utilized to acquire a sample from the target site.

Abstract: A device for treating hemorrhoids includes a housing sized and shaped for insertion to a target site within a rectum. The device also includes an inner member received within the housing such that the member may move longitudinally relative to the housing. In addition, the device includes a ligating mechanism at a distal end of the member which includes grasping arms movable between a receiving configuration in which distal ends of the arms are separated from one another and a grasping configuration in which the distal ends are drawn together to grasp tissue. The mechanism includes a ligating band received around the arms that is movable distally off of the arms to constrict around tissue grasped by the arms.

Abstract: A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.

Abstract: An implantable fluid operated device may include a fluid reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to transfer fluid between the fluid reservoir and the inflatable member. The pump assembly may include one or more fluid pumps and one or more valves. An electronic control system may control operation of the pump assembly based on fluid pressure measurements and/or fluid flow measurements received from the one or more sensing devices. The electronic control system may include an internal component installed with the implanted device, and an external component that is operable by a user to provide user input, and to receive output from the implanted device.

Abstract: According to an example, a medical device is provided. The medical device comprises a body that has a proximal end with a proximal opening to interface with a fluid delivery device. The body defines a channel from the proximal opening to a distal opening configured to emit a fluid jet along a longitudinal axis of the body. The body further includes a distal wall surface that has a surface extending in a direction transverse to the longitudinal axis and faces the distal opening to receive the fluid jet. The body also defines a space between the distal wall surface and the distal opening. The distal wall includes a protrusion configured to engage tissue.
