The invention comprises an indwelling medical device which is capable of delivering a therapeutic agent evenly along the length of the indwelling portion, including the outer wall, of the device.

Indwelling luminal devices

The present disclosure is directed toward a semi-compliant to non-compliant, conformable balloon useful in medical applications. Conformable balloons of the present disclosure exhibit a low straightening force when in a curved configuration and at inflation pressures greater than 4 atm. Balloons of the present disclosure are constructed of material that can compress along an inner length when the balloon is in a curved configuration. In further embodiments, balloons of the present disclosure can be constructed of material that sufficiently elongates along an outer arc when the balloon is in a curved configuration. As a result, medical balloons, in accordance with the present disclosure, when inflated in a curved configuration, exhibit kink-free configurations and do not cause a significant degree of vessel straightening.

Conformable balloon devices and methods

The present disclosure is directed toward a composite balloon comprising a layer of material having a porous microstructure (e.g., ePTFE or expanded polyethylene) and a thermoplastic polymeric layer useful for medical applications. The layers of the composite balloons become adhered through a stretch blow-molding process. Methods of making and using such composite balloons are also described amongst others.

Blow molded composite devices and method

The present disclosure is directed toward devices, systems and methods that reduce stress being exerted directly onto balloon seals.

Comformable balloon devices and methods

The present disclosure is directed toward a semi-compliant to non-compliant, conformable balloon useful in medical applications. Conformable balloons of the present disclosure exhibit a low or insignificant straightening force when in a curved configuration and at inflation pressures greater than 4 atm. Balloons of the present disclosure are constructed of material that can compress along an inner length when the balloon is in a curved configuration. In further embodiments, balloons of the present disclosure can be constructed of material that sufficiently elongates along an outer arc when the balloon is in a curved configuration. As a result, medical balloons, in accordance with the present disclosure, when inflated in a curved configuration, exhibit kink-free configurations and do not cause a significant degree of vessel straightening.
