Abstract
An infusion catheter includes a housing, a proximal shaft assembly, a first distal shaft assembly and a second distal shaft assembly. The housing has one or more inflation ports and one or more infusion ports. The proximal shaft assembly supports a first balloon. The first distal shaft assembly extends distally from the proximal shaft assembly and supports a first distal balloon. The second distal shaft assembly extends distally from the proximal shaft assembly and supports a second distal balloon. The first and second distal shaft assemblies define infusion openings in fluid communication with the one or more infusion ports. The infusion catheter may be inserted into a uterine cavity to occlude tubal ostia and an internal cervical OS of the uterine cavity for sealing the uterine cavity. A therapeutic agent may be delivered through the infusion catheter and into the sealed uterine cavity to treat the uterine cavity.
