The present invention generally related to a device especially useful in hernia repair and a method of using the same.
This invention generally relates to a device, especially useful for hernia repair surgery.
Hernia, denoted hereinafter for umbilical hernia, ventral hernia, postoperative ventral hernia epigastric hernia, spiegelian hernia inguinal hernia, etc. is a common medical condition in which an organ protrudes through an opening in its surrounding walls (especially in the abdominal region). Hernia is sometimes treated in a tension free repair, such as implementation of meshes, patches etc. This procedure requires the insertion of a wide mesh via a relatively small aperture such that the mesh is located in a posterior layer parallel to the abdominal wall. The insertion of the mesh implants to the abdominal wall by means of laparoscopic technique or similar medical procedures requires more than one aperture and thus the abdominal wall is punctured several times. Those procedures require anesthesia and usually demand a relatively long healing time.
One of the major problems of the above procedure is the unrolling or spreading and the positioning or deploying of the mesh inside the abdominal or the pre-peritoneal cavity. The step of unrolling the mesh, directing the right side of the mesh, positioning and fixating the mesh and positioning it in the right place usually adds significantly to the time required for carrying out the procedure. Moreover, inserting the mesh/patch into the body without a trocar may expose the mesh/patch to infections.
Some techniques suggested in the literature disclose mesh-like for treating hernia. Those techniques fail to guarantee even, complete and smooth deployment of the mesh, without formation of wrinkles, and cannot ensure full anchoring of the implant to the abdominal wall. U.S. Pat. No. 5,824,082 ('082) relates to a prosthetic hernia repair patch that can be rolled into a tube for laparoscopic delivery through a trocar and which deploys to a generally planar form when ejected from the trocar into the abdominal cavity. The deployment of the prosthetic is done by embedding a wire frame made of shape memory alloys into the prosthetic. When the prosthetic is inserted into the body it is heated thus, activated—i.e. it springs into its functional, predetermined configuration and deploys the patch. However, embedding a wire frame in a prosthetic is complicated.
Thus, there is still a long felt need for a device that is simple, will shorten the time required for the spreading and the positioning of the mesh inside the body and will be inserted via a single small-bore opening.

Reference is now FIGS. 1-2 d, which schematically present a general view of the elongate open-bored applicator 100 according to the present invention. The elongate open-bored applicator 100 has an anterior portion 11 terminated outside the body and a posterior portion 12 terminated with an orifice 13 insertable into the abdominal cavity abdominal cavity and/or pre-peritoneal and/or space and/or hollow body organs and/or natural and/or artificial orifices and/or spaces and/or post operative spaces. The elongate open-bored applicator 100 comprises at least one inflatable contour-balloon 30, which is attached to the contours of mesh 20 (the different ways of attaching the inflatable contour-balloon 30 to mesh 20 will be discussed later on in the detail description). The elongate open-bored applicator 100 may additionally comprises a second inflatable balloon (refers herein after as inflatable dissection balloon) 10. The mesh and the inflatable contour-balloon are adjusted to fit inside the applicator 100. Mesh 20 is adapted to deploy when injected outside the applicator inside the body cavity. The elongate open-bored applicator 100 additionally comprises actuating means 14 adapted to push mesh 20 throughout the applicator via said posterior orifice 13. The actuating means 14 can comprises a maneuverable pistol and/or handles operating the same (denotes as 14 in FIG. 1) or inflating pumps for inflating the inflatable dissection balloon 10 and the inflatable contour-balloon 30 (denotes as 14 in FIG. 2).
Reference is now made to figures la-lb, which schematically display wings-like means 77 adapted to anchor the elongate open-bored applicator 100 within the tissue and to thrust the tissue. The wings-like means 77 are positioned in the posterior portion 12. FIG. 1 a represent the wings-like means 77 in a semi open configuration and FIG. 1 b represents the wings-like means 77 in a fully open configuration. Activation means 78 are also provided for activating (i.e. opening and closing) the wings-like means 77. The activation or de-activation of the wings-like means 77 by the activation means 78 can be performed by sliding the activation means 78 towards and away from the posterior portion 12.
The wings-like means 77 can have the configuration as shown in FIGS. 1 c-1 d. In those figures the wings-like means 77 are fixed in their positions. Reference is now made to FIG. 2 which schematically display the elongate open-bored applicator 100 once the posterior portion 12 is inside the body. As can be seen from FIG. 2, both the inflatable dissection balloon 10 and the inflatable contour-balloon 30 are inflated so as mesh 20 is in parallel to the wall of the abdominal cavity.
The modus in which both the balloon are inflated can include different timing. For example, the inflatable contour-balloon 30 is inflated to about 50% of its volume, then the inflatable dissection balloon 10 is inflated to about 70% of its volume, and then the inflation of the inflatable contour-balloon 30 is completed.
The actuating means 14 are represented in FIG. 2 as two pumps 14 used for inflating balloons 10 and 30. It should be pointed out that the present invention is not limited to the use of two pumps. One pump can be used to inflate both balloons 10 and 20 (as seen in FIG. 2 a).
