Abstract
A serration balloon can have a number of different components and can be made in a number of different manners. One or more longitudinally extending members with periodic raised wedges can be attached to a medical balloon. They can be attached with a fiber coating, a polymer coating, or other methods. A polymer matrix can be used to bond the longitudinally extending member to the surface of the balloon. The fiber coating can be, for example, a thread or mesh that secures the longitudinally extending member to the balloon. The medical balloon can be an angioplasty balloon, such as an off-the-shelf angioplasty balloon.
Claims20
A method of manufacturing a serration balloon, comprising:
- inflating a medical balloon, the medical balloon being on a catheter;
- dipping the medical balloon in the inflated state in a polymer matrix, such that the medical balloon has first layer of the polymer matrix;
- attaching a plurality of cutting blades along a surface of the medical balloon in the inflated state, each cutting blade of the plurality of cutting blades comprising a strip of material with periodic raised wedges spaced along a length thereof;
- and
- dipping the medical balloon in the inflated state with the attached plurality of cutting blades in the polymer matrix to form an over mold, such that at least a portion of each cutting blade of the plurality of cutting blades is sandwiched between the first layer of the polymer matrix and a second layer of the first polymer matrix.
A method of manufacturing a serration balloon, comprising:
- inflating a medical balloon, the medical balloon being on a catheter;
- dipping the medical balloon in the inflated state in a polymer matrix to form a first layer of polymer matrix on an outer surface of the medical balloon;
- attaching a plurality of cutting blades to the first layer of polymer matrix along the surface of the medical balloon in the inflated state, each cutting blade of the plurality of cutting blades comprising a strip of material with periodic raised wedges spaced along a length thereof;
- and
- dipping the medical balloon in the inflated state with the attached plurality of cutting blades in the polymer matrix to form an over mold, a second layer of polymer matrix further securing the plurality of cutting blades to the first layer or polymer matrix and the medical balloon.
