摘要:
Natural orifice transenteric surgical methods and devices for placing a semi-circumferential appliance around a hollow bodily organ such as the stomach. In one alternative embodiment, such an appliance is placed in order to reduce the inner volume of the stomach.
摘要:
A surgical stapler including a “breakaway” washer that is inserted into an anvil. In various embodiments, the washer can include a circular inner portion and a circular outer portion. In one various embodiment, the outer portion may include a number of staple guide sections that define openings through which staple ends of surgical staples are driven when the surgical stapler is fired and are thereafter bent, or turned, by the anvil. In various embodiments, the staple ends may then contact and be retained by the staple guide sections so that the staple ends do not re-penetrate or otherwise re-puncture stapled tissue. In one various embodiment, the washer can be dissolvable or bioabsorbable.
摘要:
A staple cartridge including first and second staple cavities therein where the first cavity can define a first axis and the second cavity can define a second axis. In various embodiments, the first axis can be transverse to the second axis. In one embodiment, the first and second cavities can extend in directions which are not parallel to each other. In various embodiments, staples deployed from such first and second staple cavities can produce a staple pattern which can better constrict blood vessels in soft tissue and reduce blood flow therethrough.

In some embodiments, an extragastric balloon is described in which the balloon is contoured to fit a portion of the stomach but not circumscribe the stomach. In some embodiments, the extragastric balloon comprises multiple material components. In some embodiments, the extragastric balloon comprises multiple inflateable compartments. In some embodiments, the extragastric balloon is filled with one or more of a gas, liquid, solid, or foams to create portions of the balloon with differing densities or buoyancies. In some embodiments, multiple anchors contact the stomach each of which are inflateable with a fluid such as a liquid, gas, or gel.
摘要:
A device and method for remodeling or partitioning a body cavity, hollow organ or tissue tract includes graspers operable to engage two or more sections of tissue within a body cavity and to draw the engaged tissue between a first and second members of a tissue remodeling tool. The two or more pinches of tissue are held in complete or partial alignment with one another as staples or other fasteners are driven through the pinches, thus forming a four-layer tissue plication. Over time, adhesions formed between the opposed serosal layers create strong bonds that can facilitate retention of the plication over extended durations, despite the forces imparted on them by stomach movement. A cut or cut-out may be formed in the plication during or separate from the stapling step to promote edge-to-edge healing effects that will enhance tissue knitting/adhesion.
摘要:
Systems and methods are provided for reducing the effective volume of a cardiac ventricle. A ventricular volume reduction system may include a containment system or container body deliverable through a catheter into the ventricle, with the containment system or container body being fillable to occupy space within the ventricle. A ventricular volume reduction system may include a partition that sequesters a portion of the ventricle and separates it from the flow path of blood in the ventricle. Methods for reducing the effective ventricular chamber volume may include placement of the containment system, the container body or the partition within the ventricle.
摘要:
The present application describes an implant system useable for positioning an implant device such as a device useful for restricting passage of ingested food into the stomach. In one embodiment, the disclosed system includes a plurality of anchors that may be coupled to tissue within the stomach, or to a tissue tunnel formed by plicating stomach wall tissue. The anchor includes a loop. During use, the implant device is inserted through the loop and expanded such that it retains its position within the loop until removed. Instruments for implanting and explanting the implant device are also described.
摘要:
A surgical method of treating morbid obesity via bariatric procedures, carried out endoluminally and transluminally using endoscopic devices that are introduced through natural body openings without the necessity of creating any incisions in the abdominal wall.
摘要:
Various obesity treatment tools and methods are described herein, as well as treatments for other gastric-related diseases, e.g., GERD. Treatment includes reducing the size of the stomach pouch to limit the caloric intake as well as to provide an earlier feeling of satiety. This may be done by creating a smaller gastric pouch within the stomach directly from the interior of the stomach itself. The smaller pouches may be made through the use of individual anchoring devices, rotating probes, or volume reduction devices. A pyloroplasty procedure may also be performed to render the pyloric sphincter incompetent. A gastric bypass procedure may additionally be performed using a traumatic magnetic anastomoses devices so that sugars and fats are passed directly to the bowel while bypassing the stomach. Many of these procedures may be done in a variety of combinations. Treatment may create enforced behavioral modifications by discouraging the ingestion of high-caloric foods.
摘要:
Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body to create one or more plications within the hollow body organ. A tissue treatment device attached to a distal end of a flexible elongated member and has a cartridge member opposite an anvil member. The cartridge member and the anvil member are movable between a closed position and an open position relative to one another, and the cartridge member is re-loadable with a removable staple cartridge to form multiple plications within the organ with the same tissue treatment device.
