Medical device systems
View Patent ↗Medical device systems and related methods are disclosed.
1. A system, comprising:
an expandable medical balloon having a wall formed of a polymeric material and a plurality of particles uniformly dispersed within the polymeric material;
wherein the plurality of particles comprise a material selected from the group consisting of fumed silica, carbon black and combinations thereof;
wherein the plurality of particles are treated to provide surfaces of the plurality of particles with a functional group that covalently bonds the plurality of particles to the polymeric material within the wall of the balloon.
2. The system of claim 1 , wherein the plurality of particles are coated with a coupling agent.
3. The system of claim 1 , wherein the surface of each of the plurality of particles is plasma-treated.
4. The system of claim 1 , wherein the polymeric material is selected from the group consisting of polyesters, polyamides, polyurethanes, polycarbonates, polyolefins, and combinations thereof.
5. The system of claim 1 , wherein the polymeric material is selected from the group consisting of ionomers, elastomers, and combinations thereof.
6. The system of claim 1 , wherein the wall comprises at most about 50 weight percent of the plurality particles.
7. The system of claim 1 , wherein the polymeric material comprises a plurality of polymers.
8. The system of claim 1 , wherein the wall comprises multiple layers.
9. The system of claim 1 , further comprising a cutting element attached to the wall of the medical balloon.
