Abstract

See full text

A balloon catheter includes an elongated catheter shaft, an expandable balloon connected to the elongated catheter shaft, and a sheath that defines a lumen and includes a therapeutic agent disposed within the lumen. The balloon catheter further includes a first configuration and a second configuration. When in the first configuration, the expandable balloon is disposed distally from the sheath such that an outer surface of the expandable balloon does not contact the lumen. Further, when in the second configuration, at least a portion of the outer surface of the expandable balloon is disposed within the lumen of the sheath such that it contacts the therapeutic agent. At least a portion of the therapeutic agent that contacts the outer surface of the expandable balloon is transferred from the lumen of the sheath to the outer surface of the expandable balloon when the balloon catheter is in the second configuration.
