Problems solved by technology

[0016] In addition, the aforementioned subsequent filling of the prosthesis makes the surgical procedure difficult and imprecise, prolongs the operation time and complicates the operation steps
[0017] Another disadvantage of the device described in US2002 / 0052653 is that the configuration of the tip portion is suitable for piercing body tissue in order to create a prosthetic insertion channel in the body tissue

Embodiment Construction

[0038] figure 1 Shown is a device 1 for implanting a prosthesis into body tissue, in particular into tissue delimiting a patient's body passage, such as the anal canal or urinary duct or esophagus.

[0039] prosthesis in Figure 8 is particularly shown in , where it is indicated by reference numeral 12 . The prosthesis 12 can have an elongated shape, such as a cylinder or a prism, and it can be formed from a so-called hyexpan material.

[0040] Said prosthesis 12 preferably has an elongated form along the direction of extension of the axis Y-Y.

[0041] The prosthesis 12 has a cross-section of area T and preferably has a cylindrical shape.

[0042] The prosthesis 12 has a front end 19 which first exits outwardly from the device 1 , and a rear end 20 which exits outwardly from the device 1 last. The front end 19 and the rear end 20 are at a mutual distance DL, which defines the longitudinal dimension of the prosthesis 12 .

[0043] Apparatus 1 includes applicator gun 2, wh...

Abstract

A device for implanting a prosthesis 12 in a body tissue that comprises a tubular element 7, having an open end 18, through which the prosthesis 12 can exit outward and a pressure element 16 acting on a rear end 20 of the prosthesis 12 in order to facilitate the outward exit of the prosthesis 12 from the tubular element 7. The device also comprises first movement means 21 programmed for advancing the pressure element 16 inside the tubular element 7 so as to bring a front end 19 of the prosthesis 12 closer to the open end and second movement means 25 programmed for moving the tubular element 7 back with respect to the pressure element 16 a pre-established calculated amount, in a manner such that the rear end 20 of the prosthesis 12 exits outward from the open end 18.

Description

technical field [0001] The present invention relates to a device for implanting a prosthesis in tissue delimiting a passageway in the body in order to induce narrowing, ie reduction of relative cross-section, of the passageway. [0002] The invention also relates to a method for operating the device. [0003] The device according to the invention may be used to implant a prosthesis next to the anal canal, for example when it is desired to reduce the relative cross-sectional dimensions in order to treat patients affected by fecal incontinence. [0004] Alternatively, the device according to the invention may be used to implant a prosthesis into the tissue delimiting the urethra. The resulting narrowing is helpful in treating patients affected by urinary incontinence. [0005] Additionally, the device according to the invention may be used to implant a prosthesis into the mucous tissue of the esophagus when it is desired to treat patients affected by gastroesophageal reflux. ...
