DETAILED DESCRIPTION OF THE INVENTION

(10) An area that is soft, flexible, and shock-absorbing and enables soft stopping at the tip (2) portion of the shock absorber padded rigid or flexible catheter (1) resector balloon (8) that we newly developed is formed. The area which is present as a flexible area in the tip (2) portion of the catheter (1) slows down softly when the catheter (1) reaches to the last point of the organ and the tissue damage is prevented by means of the flexible pad braided (3) tip (2).

(11) This area which is located on the tip (2) of the catheter (1) is flexible and it is intended for feeling the touch of the last part or resting point. The pad at the tip (2) portion of the catheter (1), flexible spring tip (5) or flexible accordion tip (6) or flexible pad balloon tip (7) region prevents harsh contact when it comes to the end of the organ or lumen or tubular area and prevents damage to the very thin vessel, bronchus or other tissues.

(12) The pad region on the tip (2) portion of the catheter (1) is flexible and soft and prevents damage to the lumen namely the walls of the vessel, bronchus, or other tissues during its advance along the lumen. The padded rigid or flexible catheter (1) resector balloon (8) provides scraping and removing of any undesired structures that narrow the lumen without causing tissue damage at the thin and final points that it would reach by means of the flexible, soft pad texture at the tip (2) portion.

(13) The padded rigid or flexible resector balloon (8) is covered with braided mesh sheath (4) structure which is obtained by a reverse braid with reverse knots. A braid mesh sheath (4) which is obtained as a braid which is reversely braided and is with external knots is formed in order to allow the padded rigid or flexible resector balloon (8) can function, namely make scrapping and shaving processes possible. Or a balloon (8) coated with a spraying method such that it becomes embossed is obtained. This area at the tip (2) portion of the padded rigid or flexible catheter (1) resector balloon (8) to which pad section is added can be a spring or a similar material.

(14) The pad section may be obtained by means of bending like an accordion; the flexible accordion tip (6) may be manufactured from a plastic material. The pad section can be manufactured as a flexible, pad braid (3) from a material coated on the balloon (8). The pad section may be manufactured as an extension to the tip of the balloon of the scrapper material that is coated on the balloon (8). The pad section may be manufactured as a continuation of the tip (2) of the scrapping structure by means of extending the braid structure that coats the surface of the balloon (8) and reversing the same.

(15) Moreover, a flexible pad section is obtained at the tip (2) of the balloon (8) catheter (1) by means of spraying or embossing or by extending the tip (2) portion of the balloon (8) a few mm from the rigid tip of the catheter (1).

(16) This flexible pad portion will lead to a feeling of soft approach when the balloon (8) part catheter (1) is passed through the bronchoscope device and is pushed into deep areas of the bronchus and approaches to a narrow region or touches to the opposite tissue. Thus, this slow and soft approaching feeling is created with the effect of the balloon (8) which is extended or left long on the tip (2) portion of the catheter (1). The undesired complications such as damage, puncture, tear, and hemorrhage in luminal tissues are avoided by means of this flexible soft pad tip (2).

(17) The invention relates to the catheter (1) resector balloons (8) used in the treatment of any type of endoluminal-endobronchial tumoral or non-tumoral narrowing and occlusions and endovascular obstructions seen in the hollow tubular organs such as the trachea, esophagus, urinary tract, biliary tract, etc. and vessels, characterized in that, it comprises the following; at least one flexible pad section with pressure and proximity sensor and/or pad section without pressure and proximity sensor which provides soft stopping at the final wall section where the catheter (1) resector balloon (8) is applied in a soft, flexible and shock absorber manner at the tip (2) portion, prevents puncture, tear, burst or vascular damages occurred in the tissues and vessels formed as a region, undesired complications, provides stopping without giving any damage to its location.

(18) It comprises a tip (2) in the form of a pad section which serves as a flexible, pad in the continuation of the catheter (1), balloon (8) that allows feeling the touch in the tissue part that it rests or forces while it advances in the sections which cannot be seen by the surgeon during the operation.

(19) The area which is present as a flexible area in the tip (2) portion of the catheter (1) comprises a flexible pad braided (3) tip (2) which enables the catheter (1) to slow down softly when the last point of the organ is reached and prevents tissue damage and enables to stop softly in a flexible and shock absorber manner.

(20) The catheter (1), balloon (8) comprises pad, flexible spring tip (5) or flexible accordion tip (6) or flexible pad balloon tip (7) region on the tip (2) portion which prevents harsh contact when it comes to the end of the organ or lumen or tubular area and prevents damage to the very thin vessel, bronchus or other tissues.

(21) The resector balloon (8) contains a reverse or plain braided mesh braid sheath (4) on it, the tip (2) contains a reverse or plain braided flexible pad braided (3) section on it.

(22) The catheter (1) comprises at least one pressure and proximity sensor on the resector balloon (8) tip (2) that provides operation without giving damage by means of perceiving the pressure in its location.

(23) The invention is a production method of a padded rigid or flexible catheter (1) resector balloon (8), characterized in that, it comprises the following process steps; forming at least one inflatable balloon (8) on the catheter (1), forming the region in the form of flexible pad section which enables stopping without damaging vessel, tissue at the last section following the balloon (8) by means of being stretched like a pad, creating a mesh braid sheath (4) or a hard surface on the balloon (8), making the catheter (1) balloon (8) connections.

(24) A pad, flexible pad braided (3) tip (2) or flexible spring tip (5) or flexible accordion tip (6) or flexible pad balloon tip (7) region which provides stopping without giving damage to the tissue, vessel, at the tip (2) portion of the catheter (1), balloon (8) is formed.

(25) At least one pressure, and proximity sensor is formed on the catheter (1) resector balloon (8) tip (2) which provides operation without giving damage by means of perceiving the pressure in its location.
