Abstract

The present invention relates to a balloon used to make a space within the human body, which is formed by coating an elastomer onto a reticulated structure made from metal wire. The balloon can be used safely within the human body because the metal reticulated structure strengthens the pressure resistance, thereby minimizing the possibility of rupture during expansion, and makes relatively elaborate surgical operations possible because the metal reticulated structure itself shows on the X-ray monitor during operations and so makes it easy to ascertain the balloon's position, state of expansion and the like.

Description

Balloon used to form a cavity in the human body,

The present invention relates to a balloon that is used to form a cavity in the human body.

In case of using a balloon to form a cavity in the human body and the like when restoring a narrowed blood vessel and damaged vertebrae. In the following, it is described in more detail throughout the course of treatment of vertebral compression fractures balloon sisulbeop reversal.

Treatment of the balloon sisulbeop of vertebral compression fracture reconstruction is, the first, pressure inserted to elongate special tube to the refractive part and pressed by them into the balloon catheter (1, 100), inflating the balloon 110 through the refractive portion Lift as a normal height, the process removes the balloon and lifting makin done by filling in the space took place in the bone cement, by in the inflatable balloons 110, the pressure refractive region as normal height of a cavity in bone process may be represented otherwise as a.

In the case of forming the cavity as described above, it is added to a great pressure on the balloon. Therefore, the balloon of the elastomeric single structure as shown in Fig. 2 is a lingering danger of rupture during the procedure. If the bubble bursts, the road, but concerns the problem that the probe and the body of the metal material of the catheter in contact, and the fear of remaining in not being a fragment of a bursting bubble collecting bones, the procedure is delayed to increase the suffering of patients problems can also be caused. Therefore, in order to secure treatment for vertebral compression fractures balloon procedure it requires swift resolution of problems as described above.

On the other hand, in order to determine the body position of the balloon during balloon surgery vertebral compression fractures with X-Ray have a marker with platinum on the inner catheter is attached, and must be injected into the expensive dye. However, even meet these conditions, because the position of the balloon on the monitor will only be dimly read, to develop a way to determine the position and shape of the balloon to a higher resolution is required for precise treatment.

The present invention, for solving the problem as described above of the prior art,

First, it is an object of the invention to provide a balloon that is used to form a cavity in the human body, the pressure resistance is improved by minimizing the possibility of rupture during inflation.

Second, without the use of a marker with platinum and high contrast of the road, and an object thereof is to provide a balloon that is used to form a cavity in the human body monitoring is possible, such as the position and shape of the inflated balloon.

The invention,

Molded by coating an elastomer on a reticular structure formed of a metal wire, there is provided a balloon that is used to form a cavity in the human body.

The mesh structure may be knitted in the form of a braided metal wire.

The mesh structure may be knitted in the form of a braided metal wire of a strand.

Balloons of the present invention, since the possibility of rupture during inflation to minimize reinforce the strength for pressure resistance of a metal reticular structure can be safely used in humans.

In addition, easy to grasp, such as the position and shape of the inflated balloon and because the metal reticular structure itself to appear on the X-Ray Monitor allows for more elaborate treatment.

In addition, eliminating the need for the marker and expensive dye separately with platinum in order to identify the position of the balloon is economical.

The present invention relates to a balloon that is used to form a cavity within the human body formed by the elastomer coating on the mesh structure formed of a metal wire.

The balloons are used for the balloon catheter, such apparatus which is used when restoring the narrowed blood vessel or the like is damaged vertebrae.

The network structure can be prepared in various forms without limitation. For example, a method of manufacturing cross-coupled by a number of metal wire and, and a method for producing a knitted fabric to form a braided metal wire.

However, in the present invention because when the balloon expanded metal mesh structure is also to be expanded it is preferably made of a knitted fabric form a braided metal wire. Because, between when the braided mesh structure of a metal wire loop (loop) with a loop (loop), because the expansion margin generated for enabling an expansion of the network structure at the time of balloon inflation because they can be made of the balloon expands gently to be.

Expansion margin in the braid may be controlled by the method.

In the network structure it can also be braided with metal wires of the various braided of metal wire of a strand when the two strands braided or more strands. However, it is preferred that the braid of a metal wire of a strand in order to produce a solid form of a mesh structure.

The type of the metal wire in the present invention is not specifically restricted, since for use in the human body, it is preferable to use a material suitable for medical use, such as stainless steel.

In the present invention, as long as the elastomer has a smooth expansion and contraction of the balloons it is not particularly restricted but, because of using in the human body, it is preferable to use a material suitable for medical use, such as polyurethane-based elastomer.

Balloon used to form a cavity in the body of the present invention may be applied in a variety of pre-sale. For example, there can be used very useful in a balloon catheter used in spinal compression fracture balloon procedure.

Method for producing a balloon of the present invention is not particularly limited. For example, it is possible to refer to the production step of the hose, which is known, comprises a network structure in which, balloons of the invention may be easily produced in addition to such a process by adding a step of molding a balloon shape.

For example, using a mold according to the elastomer solution to be supplied to the extruder using the extrusion apparatus, the method of covering a pre-manufactured mesh structure that is transferred along the mandrel provided at the center of an extrusion die extruded into a tube shape, and it known and it can be prepared in the form of a balloon molding.

Hereinafter, it will be described in detail preferred embodiments of the invention with reference to the accompanying drawings. If the specific description of the above, well-known functions and configuration determines may unnecessarily obscure the subject matter of the present invention to illustrate the present invention and description thereof will be omitted.

3 illustrates the shape of the reticular structure (10, 20) formed of a metal wire (14, 24) according to the present invention; In Figure 3 (a) and (b) shows another network structure (10, 20) on a tubular braid in a different way. The mesh structure looking at the knitted state metal wire (14, 24) at 10 and 20, a loop (loop) with a loop (loop), the expansion allowance that allows the expansion of the network structure at the time of balloon inflation between ( 12, 22) it can be seen that is formed.

The produced mesh structure is coated with an elastomer in equipment such as extruders and extruded into a tube shape, formed by it using a mold according to known methods to produce a balloon shape.

Figure 4 shows a balloon of the present invention. In Figure 4 (a) shows a shape before expansion (b) shows the inflated state. FIG expansion margin 12 at the 4 (a) will be presented to be drawn when air flows into the balloon 30 to expand the mesh structure 10, the balloon is inflated to a predetermined size.

The above description is only to those described as the technical idea of ​​the present invention by way of example, if a person of ordinary skill in the art would be a modified embodiment without departing from essential characteristics of the present invention. Thus, the technical idea of ​​the present invention is not limited to the above embodiment.
