Abstract
The present disclosure is directed to balloon catheters including a PFAS-free balloon protector and stent delivery systems including the balloon catheters. For instance, the present disclosure is directed to a balloon catheter including a balloon and a balloon protector extending about at least a portion of the balloon, wherein the balloon protector is made from a material comprising a dispersion of a polyamide and a lubricious polyethylene, where a weight ratio of the polyamide and the lubricious polyethylene is in a range from about 8:1 to about 20:1.
Claims20
A balloon catheter comprising:
- a balloon;
- and
- a balloon protector extending about at least a portion of the balloon, wherein the balloon protector is made from a material comprising a dispersion of a polyamide and a lubricious polyethylene, wherein a weight ratio of the polyamide and the lubricious polyethylene is in a range from about 8:1 to about 20:1.
A balloon delivery catheter comprising:
- a balloon catheter including a balloon;
- and
- a balloon protector extending at least partially about the balloon, wherein the balloon protector is made from a dispersion of a polyamide, a lubricious polyethylene, and a carboxylic acid-based compatibilizer.
A balloon delivery system comprising:
- a balloon catheter including a balloon and outer sheath;
- and
- an elongated tubular balloon protector extending at least partially about the balloon;
- and wherein the elongated tubular balloon protector is made from a dispersion of a polyamide, a high-density polyethylene (HDPE), and a carboxylic acid based compatibilizer, wherein a combined weight of the polyamide, the HDPE, and the carboxylic acid based compatibilizer are equal to a total weight of the elongated tubular balloon protector, wherein the elongated tubular balloon protector is per- and polyfluoroalkyl substance (PFAS)-free, wherein the elongated tubular balloon protector has a rough, non-uniform exterior surface as compared to an exterior surface of a PFAS based balloon protector, and wherein the elongated tubular balloon protector exhibits a reduced removal force compared to a removal force of the PFAS based balloon protector.
