    摘要： Surgical scissors include a pair of scissor blades mounted at a distal end of an elongated flexible body and a housing attached to the proximal end of the elongated body. An actuator is coupled with mechanical advantage to the scissor blades for manually controlling shearing movement of the blades in response to finger movement on the actuator back and forth along the housing. Electrical conductors are provided through body and housing from a connector to the scissor blades. The housing is configured to be assembled in mating shells with components assembled in and confined by attached shells that facilitate rapid and accurate fabrication.

    摘要： A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis that can be skewed relative to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, a surgeon locates a vessel and side branch of interest and extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be deflected to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to the surgical tool. Removable, transparent tips are selectively positioned at the distal end of the cannula for performing dissection and transection via a single cannula. Additionally, the tips are configured to align the apices of the tips with the central axis of the endoscope to maximize the visual field through the tips via the endoscope. Wing-like protrusions on an alternate tip for the cannula facilitate tissue dissection in forming a tunnel in tissue along a target vessel. Swept back forward edges on the wing-like protrusions promote easy dissection using reduced force to advance the cannula and alternate tip tough tissue surrounding the target vessel.

    摘要： Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach. In an alternative embodiment, an expansion structure on the distal end of the elongate portion expands and/or contracts the medical implant to facilitate positioning.

    摘要： Transvascular access devices and methods for transvascular access are provided. The transvascular access devices can include a guidewire lumen and a guide tube and stylet disposed in a second lumen. The guide tube can be used to control the orientation of the stylet and provide additional support for the stylet. The methods include providing a second entry point in a vessel of a patient remote from a first entry point. A vascular catheter can enter the vascular system of a patient at a first entry point and be advanced to a second entry point. A guide tube can be advanced out the second lumen of the vascular catheter with a stylet advanced out of the guide tube to pierce the vessel wall and skin of the patient at the second entry point. A catheter can be introduced to the vascular system at the second entry point.

    摘要： Described herein are endoscopic plicators passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.
