I - la GASTRIC BAND INTRODUCTION DEVICE Background of the Invention [00011 Over the years many methods of treating morbid obesity have been undertaken. One of the more promising methods employs the placement of a circumscribing band, commonly known as a "gastric band", around a portion of the stomach whereby the stomach may be compressed thereby creating a stoma opening that is smaller than the normal interior diameter of the stomach thereby restricting food intake into the lower digestive portion of the stomach. 100021 Typically, the gastric band is introduced into a patient's abdomen by pushing it through a large trocar or trocar site by hand. This method of introduction increases the risk of infection resulting from the gastric band contacting the patient's skin. Inserting the gastric band directly through a trocar may also undesirably damage the gastric band. Consequently, a significant need exists for a surgical instrument that enables the introduction of a gastric band into a patient's abdomen without coming in direct contact with the patient's skin or trocar. Brief Summary of the Invention [00031 The present invention overcomes the above noted and other deficiencies in the prior art by providing a surgical instrument that allows for the introduction of a gastric band into a patient's abdomen without allowing the gastric band to contact the patient's skin or a trocar. 100041 Accordingly, in one aspect, the present invention provides a surgical instrument for deploying an adjustable gastric band including, an elongated support tube having a proximal end and a distal end, an elongated inner rod having a proximal end and a distal end from which a gastric band is deployed, wherein said distal end includes a shelf for supporting a gastric band at said distal end, having one or more pins disposed thereon for releasably engaging a gastric band, wherein said MAGrahan\Clare\Speci & Amndmts\19272 Rspns Amndmis Speci.Docx, 16/03/12 -2 inner rod is slidably and coaxially disposed within said support tube and wherein said distal movement of said rod exposes said shelf. 100051 In another aspect, the present invention provides a combination of a surgical instrument for deploying an adjustable gastric band including, an elongated support tube having a proximal end and a distal end, an elongated inner rod having a proximal end and a distal end from which a gastric band is deployed, wherein said distal end includes a shelf for supporting a gastric band at said distal end, having one or more pins disposed thereon for releasably engaging a gastric band, wherein said inner rod is slidably and coaxially disposed within said support tube and wherein said distal movement of said rod exposes said shelf, and a gastric band, wherein the gastric band is releasably secured to said distal end of said inner rod, wherein said distal movement of said rod exposes said gastric band. 10005a] In a further aspect, the present invention provides a surgical system, including, a surgical instrument, including, an elongated support tube having a proximal end, a distal end and an inner surface having a longitudinal groove therein and an elongated inner rod having a proximal end, a distal end and a longitudinal protrusion, wherein said inner rod is slidably and coaxially disposed within said support tube, wherein said longitudinal protrusion is slidably engaged with said longitudinal groove of said inner surface of said elongated support tube and a gastric band releasably secured to said distal end of said inner rod, wherein said distal movement of said rod exposes said gastric band.

I is an isometric view of an unactuated gastric band introduction device; M:\Graham\Clare\Speci & Amndmts\19272 Rspns Amndmis Speci.Docx, 16/03/12 - 2d 100091 FIG. 2 is an isometric view of an actuated gastric band introduction device; 100101 FIG. 3 is a partial side view of the distal end of the inner rod of gastric band introduction device; M\Graham\Clare\Speci & Amndmts\i9272 Rspns Amndmts Speci.Docx, 16/03/12 100111 FIG. 4 is an isometric view of an actuated gastric band introduction device with the gastric band partially removed from the inner rod; and [0012] FIG. 5 is an enlarged partial view of the isometric view of FIG. 4 showing the distal end of the inner rod with the gastric band partially removed. Detailed Description of the Invention 100131 Referring now to the Figures wherein like numerals indicate the same elements throughout the views, there is shown in FIG. I an isometric view of an unactuated gastric band introduction device 10 ready for introduction into a patient. The gastric band introduction device 10 includes an elongated support tube 2 with a handle 7 at a proximal end. The gastric band introduction device 10 preferably includes a pair of opposed finger loops 3 extending outwardly from the handle 7. An inner rod 5 is slidingly located within the support tube 2 and has a thumb ring 4 at a proximal end and one or more upwardly protruding pins 6 for engaging a gastric band 20 at the distal end. The inner rod 5 may also include a shelf 11 located at the distal end of the support tube 2 for holding a gastric band 20. The inner rod 5 may also include a longitudinal protrusion 12 which may engage a longitudinal groove (not shown) in the support tube 2 for effecting the sliding engagement between the inner rod 5 and support tube 2 and also for stabilizing the inner rod 5 when it is inserted into the support tube 5. 100141 The support tube 2 is preferably comprised of stainless steel but may be comprised of any durable engineering plastic. Preferably, the support tube 2 has a diameter of about 10mm to about 20mm and more preferably between about 12mm and about 15mm. Preferably, the support tube 2 is between about 30cm and about 50cm in length and more preferably about 43cm. However, it should be appreciated that the support tube 2 can be adapted in both length and diameter to accommodate any kind of gastric band or to fit within any sized trocar. The handle 7, the finger loops 3, the inner rod 5, and the thumb ring 4 can be comprised of either stainless steel or any suitably durable engineering plastic. While pins 6 are shown in the illustrative embodiment, any other mechanism, such as a clip or a strap, which will releasably secure the gastric band to the inner rod while also allowing the gastric band to be easily removed from the inner rod will suffice. 100151 FIGS. 2 through 5 show the gastric band introduction device 10 after the device has been actuated to deploy a gastric band 20 from the distal end of the support tube 5. In FIGS. 2 through 5, the inner rod 5 has been fully inserted into the support tube 2 and has pushed the gastric band 20 from the distal end of the support tube 5. Once the gastric band 20 has been deployed, the gastric band 20 can be removed from the inner rod 5. 100161 In use, the gastric band introduction device, in an unactuated state, is inserted into a trocar placed in the patient's abdomen. The device is then actuated by sliding and inserting the inner rod fully into the support tube, thereby deploying the gastric band. The gastric band is then removed from the inner rod by the dissector to be placed around the stomach. Once the gastric band has been removed, the inner rod is pulled back out of the support tube, and the device removed from the trocar. 10017] While the present invention has been illustrated by the description of several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications may readily appear to those skilled in the art.
