Abstract
A system for treating uterine tissue having a seal assembly configured for positioning in a patient's cervical canal and uterine cavity; an expandable distal balloon portion; an expandable elongate medial balloon portion configured for movement between a first transversely expanded shape for engaging a cervical canal and a second transversely non-expanded shape for trans-cervical insertion; and a fluid source in communication with distal balloon portion and medial balloon portion for expansion of said balloon portions.
Claims20
A system for transcervical introduction to a patient's uterus, said system comprising:
- a radially expandable sleeve having a proximal end, a distal end, and a central passage therebetween, said sleeve being adapted to be introduced into a patient's cervix in a reduced width configuration and to be immobilized in the patient's cervix in an expanded width configuration;
- wherein the sleeve includes a distal balloon and a ridge region extending proximal of the distal balloon, the ridge region including a plurality of ridges and valleys alternatingly disposed along a length thereof;
- an inflation port in fluid communication with both an interior of the distal balloon and an interior of the ridge region;
- and
- a probe shaft slidably received in the central passage of the sleeve, wherein the probe shaft may be advanced and retracted within the central passage while the sleeve remains immobilized in the patient's cervix.

- a radially expandable sleeve having a proximal end, a distal end, and a central passage therebetween, said sleeve being adapted to be introduced into a patient's cervix in a reduced width configuration and to be immobilized in the patient's cervix in an expanded width configuration;
- wherein the sleeve includes a distal balloon and a plurality of ridges and valleys alternatingly disposed along a length of the sleeve proximal of the distal balloon;
- a pressurized fluid source fluidly connected to an interior of the sleeve to inflate the plurality of ridges and the distal balloon;
- and
- a probe shaft slidably received in the central passage of the sleeve, wherein the probe shaft may be advanced and retracted within the central passage while the sleeve remains immobilized in the patient's cervix.

- a pressurized fluid source fluidly connected to an interior of the sleeve to inflate the ridge region and the distal balloon to transition the sleeve from the reduced width configuration to the expanded width configuration;
- and
- a probe shaft slidably received in the central passage of the sleeve, wherein the probe shaft may be advanced and retracted within the central passage while the sleeve remains immobilized in the patient's cervix;
- wherein a length of the ridge region decreases when the sleeve transitions from the reduced width configuration to the expanded width configuration.
