The method uses a device which is small enough to be inserted and withdrawn through a thoracoport. The device includes a proximal end configured to be gripped by a surgeon and a distal end configured to be inserted into the patient. A stainless steel shaft connects the distal and proximal ends of the abrading device. The distal end includes a series of nylon bristles. The bristles are attached to the device wire wrapped around the distal end of the device. The connecting shaft and wrapped wire are malleable. Once the device is inserted, the surgeon grips the proximal end and manipulates the device so that the series of nylon bristles abrades the walls of the pleural space. Once the abrading process is complete, the surgeon can easily withdraw the device back through the thoracoport. ## Claims ### Claim 1 A method for abrading a membrane located in a patient's body for a thoracic surgical action, said surgical action involving a pleural membrane, a parietal pleura, a pleural cavity, and an opening in said patient's body, comprising: a. providing a thoracoport having an inner diameter, b. providing an abrading device, including, i. a proximal end and a distal end, ii. a handle located on said proximal end, iii. a brush located on said distal end, iv. a shaft connecting said distal end and said proximal end, wherein said shaft has an outer diameter, wherein said outer diameter is smaller than said inner diameter of said thoracoport, v. said brush having a plurality of bristles, vi. said distal end having a smooth, rounded tip extending distally from the brush; vii. wherein said smooth, rounded tip is created using liquid acrylic, viii. wherein said thoracoport is independent of said abrading device; c. inserting said thoracoport into said pleural cavity by passing said thoracoport through said opening, d. inserting said abrading device through said thoracoport; e. placing said brush against said parietal pleura in a position where, said plurality of bristles rest against said parietal pleura, said handle remains outside said patient's body; and f. abrading said parietal pleura of said pleural membrane so that said pleural membrane adheres to itself. ### Claim 2 (depends on 1) The method for abrading a membrane located in a patient's body as recited in claim 1, wherein said plurality of bristles fasten to said distal end by wrapping one malleable wire around said plurality of bristles and said distal end. ### Claim 3 (depends on 2) The method for abrading a membrane located in a patient's body as recited in claim 2, wherein said bristles form a helical pattern axially along said abrading device. ### Claim 4 (depends on 2) The method for abrading a membrane located in a patient's body as recited in claim 2, wherein said wire is made of non-corrosive stainless steel. ### Claim 5 (depends on 1) The method for abrading a membrane located in a patient's body as recited in claim 1, wherein said plurality of bristles are made of anti-bacterial nylon. ### Claim 6 (depends on 1) The method for abrading a membrane located in a patient's body as recited in claim 1, wherein said shaft is made of non-corrosive stainless steel. ### Claim 7 (depends on 1) The method for abrading a membrane located in a patient's body as recited in claim 1, wherein said shaft is malleable. ### Claim 8 A method for abrading a membrane located in a patient's body for a thoracic surgical action, said surgical action involving a pleural membrane, a parietal pleura, a pleural cavity, and an opening in said patient's body, wherein a thoracoport, having a first opening and a second opening, is inserted into said opening in said patient's body, comprising: a. providing an abrading device, including, i. a proximal end and a distal end, ii. a handle located on said proximal end, a brush located on said distal end, and a shaft therebetween, iii. said brush having a plurality of bristles, iv. said distal end having a smooth, rounded tip extending distally from the brush; v. wherein said smooth, rounded tip is created using liquid acrylic, vi. wherein said abrading device is independent of said thoracoport; b. inserting said abrading device into said thoracoport by passing said distal end into said first opening, such that said brush extends out of said second opening but at least a portion of said shaft remains within said thoracoport; c. placing said brush against said parietal pleura in a position where, i. said plurality of bristles rest against said parietal pleura, ii. said handle remains outside said patient's body; and d. abrading said parietal pleura of said pleural membrane so that said pleural membrane adheres to itself. ### Claim 9 (depends on 8) The method for abrading a membrane located in a patient's body as recited in claim 8, wherein: a. said plurality of bristles fasten to said distal end by wrapping one malleable wire around said plurality of bristles and said distal end; and b. said bristles form a helical pattern axially along said abrading device. ### Claim 10 (depends on 9) The method for abrading a membrane located in a patient's body as recited in claim 9 wherein said wire is made of non-corrosive stainless steel. ### Claim 11 (depends on 8) The method for abrading a membrane located in a patient's body as recited in claim 8, wherein said distal end is dipped into liquid acrylic. ### Claim 12 (depends on 11) The method for abrading a membrane located in a patient's body as recited in claim 11, wherein said liquid acrylic dries in order to create said smooth, rounded tip. ### Claim 13 (depends on 8) The method for abrading a membrane located in a patient's body as recited in claim 8, wherein said plurality of bristles are made of anti-bacterial nylon. ### Claim 14 (depends on 8) The method for abrading a membrane located in a patient's body as recited in claim 8, wherein said shaft is made of non-corrosive stainless steel. ### Claim 15 (depends on 8) The method for abrading a membrane located in a patient's body as recited in claim 8, wherein said shaft is malleable.
