Abstract
A soft flexible tipped balloon for a medical device, the balloon comprising a first balloon segment made of a first polymer material, a second balloon segment made of a second polymer material, the second polymer material different from the first polymer material, and a third balloon segment made of a third polymer material, the third polymer material different from the second polymer material and optionally different from the first polymer material, the segments arranged sequentially along the length of the balloon and processes of making the same.
Claims32
A balloon for a medical device, the balloon comprising a plurality of balloon segments, at least two of the segments made of different polymer materials, the plurality of segments arranged sequentially along the length of the balloon, the balloon having a distal portion, a body portion and a proximal portion, the distal portion softer than the body portion of the balloon as measured by the Shore D hardness scale.
A balloon for a medical device, the balloon formed of a proximal segment and a distal segment, each segment made of a different polymer material, the distal segment made of a softer material than the proximal segment, the segments arranged sequentially along the length of the balloon.
A balloon for a medical device formed of three segments, a first balloon segment made of a first polymer material, a second balloon segment made of a second polymer material, the second polymer material different from the first polymer material, and a third balloon segment made of a third polymer material, the third polymer material different from the second polymer material and different from the first polymer material, the segments arranged sequentially along the length of the balloon.
