Surgical device for providing access to a surgical site
First Claim
1. A method for positioning a surgical device in a human or animal body, the surgical device being suitable for application in a treatment performed on the human or animal body with an aim of providing access to a surgical site in the body, the surgical device comprising:
- at least one inflatable chamber configured to be inflated from a collapsed state to an expanded state, wherein the at least one inflatable chamber comprises at least one wall, the at least one wall forming a first set of multiple inflatable chambers of the at least one inflatable chamber, which are in fluid connection, the chambers formed by the at least one wall are laterally contiguous, two neighboring chambers are laterally connected at a seam and each of the two neighboring chambers convexly bulges towards the seam, wherein the at least one wall is formed as a sheeting comprising two opposing layers of deformable material, the sheeting forming the multiple inflatable chambers connected at the seam, the seam being formed according to a predetermined pattern by having a connection of the two opposite layers at the seam, wherein the sheeting comprises a third layer interposed between the two opposing layers, andat least one elongated flexible member, each elongated flexible member having a proximal end operatively connected to the surgical device, the method comprising the steps of;
inserting the surgical device in the collapsed state into the body,inflating the at least one inflatable chamber to the expanded state such that the surgical device exerts a force on an organ or tissue at said surgical site,guiding a distal end of the at least one elongated flexible member outside of the body,positioning the distal end at a fixation site such that the at least one elongated flexible member is adapted to position the surgical device, andfixing the distal end at the fixation site to fix the position of the surgical device.

Abstract
A surgical device (5) for application in a treatment performed on the human or animal body (1) with the aim of providing access to a surgical site in the body, includes at least one inflatable chamber (70, 71, 72) which can be inflated from a collapsed state to an expanded state, in which expanded state the device is suitable for exerting a force on an organ or tissue at the surgical site, at least one elongated flexible member (8, 80), which member at its proximal end (801) is operatively connected to the device, and which member has a length to allow the distal end (800) of the member to be fixed to a fixation site (100, 101) outside of the body, and methods of using this device.
