Obesity has been a problem for many years. A variety of methods and devices have been used to try to address obesity in patients, including gastric bypasses and implanted devices. Biosurgical adhesives have also been used in a variety of ways in various medical procedures. An exemplary adhesive is disclosed in U.S. Pub. No. 2004/0190975, the disclosure of which is incorporated by reference herein. While several systems and methods have been made and used for addressing obesity, and while adhesives have been used in various other medical procedures, it is believed that no one prior to the inventors has made or used the invention described in the appended claims.
While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description of certain examples taken in conjunction with the accompanying drawings, in which like reference numerals identify the same elements and in which:
The following description of certain examples of the invention should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments, and advantages of the invention will become apparent to those skilled in the art from the following description, which is by way of illustration, one of the best modes contemplated for carrying out the invention. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.
As shown in
The suction device (20) comprises a head (22) coupled with a flexible tube (24). As shown head (22) has an annular, outwardly flared rim (26), and is in fluid communication with flexible tube (24). Rim (26) is configured to sealingly engage an inner stomach surface (104). As shown in

As shown in
In another embodiment, matrix cloth (70) contains adhesive (60), such that a separate applier (40) is not needed to apply adhesive (60). For instance, cells (72) may contain adhesive (60). Alternatively, matrix cloth (70) material may itself be adhesive, with no adhesive (60) being provided within cells (72). In this variation, portions of matrix cloth (70) may adhere to outer surface (106) and/or to other portions of matrix cloth (70). This may permit contact between adjacent outer surface (106) portions through voids provided by empty cells (72), which may result in fusion of such adjacent outer surface portions (106). Alternatively, matrix cloth (70) may be substituted with any suitable alternative, supplemented with other structures or substances, or may be omitted altogether. To the extent that a matrix cloth (70) is used, suitable methods for applying matrix cloth (70) will be apparent to those of ordinary skill in the art.
In the present example, as shown in
In one variation, and as shown in
In one embodiment, as shown in
Gripping jaw members (124) are pivotally connected relative to shaft (122), such that jaw members (124) may be selectively provided in an open or closed positions. Each gripping jaw member (124) has a plurality of teeth (126). Teeth (126) are configured to grip tissue, such as inner stomach surface (104). Gripping jaw members (124) may be operable to open and close via cables (not shown). Cables in the present example extend through shaft (122) to a user input device (not shown). Of course, any suitable alternative to cables may be used to open and/or close gripping jaw members (124).
Gripping instrument (120) of the present example further comprises a vacuum port (140). Vacuum port (140) may have a configuration similar to that of head (22) on suction device (20). In the present example, vacuum port (140) has a diameter that is less than the diameter of head (22) on suction device (20). Vacuum port (140) is in fluid communication with vacuum lumen of shaft (122). Vacuum port (140) may be used to secure inner stomach surface (104) relative to gripping jaw members (124), such as before gripping jaw members (124) are used to grip inner stomach surface (104).
In use, matrix cloth (70) and adhesive (60) are applied to outer stomach surface (106). Gripping instrument (120) is positioned adjacent inner stomach surface (104), substantially opposite of matrix cloth (70) and adhesive (60). With gripping jaw members (124) in an open position, vacuum is applied through vacuum port (140), securing inner stomach surface (104) relative to gripping jaw members (124), as shown in
An exemplary variation of gripping instrument (120) is shown in
Gripping jaw members (224) are pivotally connected relative to shaft (222), such that jaw members (224) may be selectively provided in an open or closed positions. Each gripping jaw member (224) has a plurality of teeth (226). Teeth (226) are configured to grip tissue, such as inner stomach surface (104). Gripping jaw members (224) may be operable to open and close via cables (230). Cables (230) in the present example extend through shaft (222) to a user input device (not shown). Of course, any suitable alternative to cables (230) may be used to open and/or close gripping jaw members (224).
Each gripping jaw member (224) comprises a generally spherically-shaped joint portion (228). Joint portions (228) are configured to overlap within shaft (222) while gripping jaw members (224) are in an open position. Each gripping jaw member (224) also has a cup-like configuration, which is configured to provide a vacuum chamber (240). Such vacuum chambers (240) are in fluid communication with lumen (250), such that a vacuum may be provided within vacuum chambers (240) via lumen (250). In another variation, a cover (not shown) having a plurality of apertures is provided over each vacuum chamber (240). Alternatively, any other structural variation of gripping jaw members (224) may be used.
While lumen (250) is depicted as generally being the interior of shaft (222), it will be appreciated that lumen (250) may alternatively be provided by a separate member (not shown) inserted through shaft (222). Other structural variations will be apparent to those of ordinary skill in the art.
In an exemplary use, gripping instrument (220) is used in a manner similar to the use of gripping instrument (120) described above. However, instead of suction being provided through vacuum port (140), suction is provided through vacuum chambers (240) of gripping jaw members (224). Such suction may be provided before and during the gripping of inner stomach surface (104) of teeth (226), and may assist teeth (226) in the gripping of inner stomach surface (104). Suction may continue to be provided as gripping jaw members (224) are brought to a closed position, whereupon an invaginated portion (202) is created.
As will be appreciated by those of ordinary skill in the art, the creation of invaginated portions (102, 202) may result in a reduction of stomach (100) volume. Such reduction in stomach (100) volume may (or may not) provide a method for treating morbid obesity in a patient, and/or may provide other results. Other suitable structural variations of suction device (20) and gripping instruments (120, 220), as well as variations of uses for the same, will be apparent to those of ordinary skill in the art.
It will be appreciated that the invagination systems (10) described herein, including variations of the same, may be used in laparascopic, endoscopic, open, and/or other surgical settings, including combinations thereof.
Embodiments of the present invention have application in conventional endoscopic and open surgical instrumentation as well as application in robotic-assisted surgery.
Embodiments of the devices disclosed herein can be designed to be disposed of after a single use, or they can be designed to be used multiple times. Embodiments may, in either or both cases, be reconditioned for reuse after at least one use. Reconditioning may include any combination of the steps of disassembly of the device, followed by cleaning or replacement of particular pieces, and subsequent reassembly. In particular, embodiments of the device may be disassembled, and any number of the particular pieces or parts of the device may be selectively replaced or removed in any combination. Upon cleaning and/or replacement of particular parts, embodiments of the device may be reassembled for subsequent use either at a reconditioning facility, or by a surgical team immediately prior to a surgical procedure. Those skilled in the art will appreciate that reconditioning of a device may utilize a variety of techniques for disassembly, cleaning/replacement, and reassembly. Use of such techniques, and the resulting reconditioned device, are all within the scope of the present application.
By way of example only, embodiments described herein may be processed before surgery. First, a new or used instrument may be obtained and if necessary cleaned. The instrument may then be sterilized. In one sterilization technique, the instrument is placed in a closed an sealed container, such as a plastic or TYVEK bag. The container and instrument may then be placed in a field of radiation that can penetrate the container, such as gamma radiation, x-rays, or high-energy electrons. The radiation may kill bacteria on the instrument and in the container. The sterilized instrument may then be stored in the sterile container the sealed container may keep the instrument sterile until it is opened in a medical facility. A device may also be sterilized using any other technique known in the art, including but not limited to beta or gamma radiation, ethylene oxide, or steam.
Having shown and described various embodiments of the present invention, further adaptations of the methods and systems described herein may be accomplished by appropriate modifications by one of ordinary skill in the art without departing from the scope of the present invention. Several of such potential modifications have been mentioned, and others will be apparent to those skilled in the art. For instance, the examples, embodiments, geometries, materials, dimensions, ratios, steps, and the like discussed above are illustrative and are not required. Accordingly, the scope of the present invention should be considered in terms of the following claims and is understood not to be limited to the details of structure and operation shown and described in the specification and drawings.
