Definitions
- the invention relates to an expandable balloon for balloon catheters according to the preamble of claim 1.
- Balloon catheters are provided with a balloon on their tip, on which, for example, a stent can be attached. This arrangement is inserted into a stenosis of a patient's blood vessel. The balloon is expanded in the stenosis in order to expand the stent and to place it permanently in the stenosis in the course of this process.
- the balloon body of the balloon in its unfolded state has an outer surface on which areas with a high coefficient of friction and areas with low Point the coefficient of friction outwards.
- the areas with a high coefficient of friction prevent the balloon from sliding out undesirably when the balloon is expanded within the stenosis.
- the balloon body when folded, has an outer surface on which at least predominantly only areas with a low coefficient of friction are arranged and point outwards. This ensures that the insertion of the balloon catheter through the areas with a high coefficient of friction is not impeded.
- This arrangement is made possible in that in the course of the folding of the balloon body the areas with a high coefficient of friction are transferred into the interior of the fold, so that only or predominantly only areas with a low coefficient of friction are arranged in the folded state on the outer surface then formed and after show outside.
- the balloon body from a material with a high coefficient of friction, and only the areas with low friction to generate exercise coefficients by applying coatings with this coefficient of friction.
- Fig. 1 is a schematically simplified cross-sectional view of a balloon according to the invention in the folded state
- Fig. 2 is a representation of the balloon corresponding to FIG. 1 in the unfolded state.
- an expandable balloon 1 is provided for a balloon catheter, which is shown schematically in simplified form in FIG. 1 and is identified by reference number 8.
- the balloon 1 has a balloon body 2, which is shown in the folded state A in FIG. 1.
- the folded state of the balloon body 2 results in four folds in the example, which lead to an outer surface shape 9. As illustrated in FIG. 1, four areas 10, 11, 12 and 13 are arranged on the outer surface 9, which represent areas with a low coefficient of friction.
- an outer surface 3 results, on which the regions 4 to 7 with a high coefficient of friction like the regions 10 to 13 with a low coefficient of friction to the outside point.
- the balloon can be inserted into a vessel in a simple manner and without great resistance to movement, since only areas with a low coefficient of friction come to rest on the outer surface 9 which is effective in this state.
