Abstract: Transcervical access systems for providing transcervical movement of fluids are described. The transcervical access systems are effective for transferring a broad range of fluids, including the delivery of hydrogel precursors, saline, and imaging fluids, to the uterine cavity. The transcervical access systems are also effective for removing fluids from the uterine cavity, such as residual bodily fluids, residual fluids from a procedure, or tissue. The transcervical access systems described include flow limiters, such as egress limiters and/or cervical plugs. Methods of use of the transcervical access systems are also described. Methods include using the transcervical access systems to transcervical access the uterine cavity and install hydrogel. The transcervical access systems and associated methods can be useful for providing degradable hydrogel in the uterine cavity, including the cervical canal, for the prevention of adhesions following intrauterine procedures.

Abstract: Medical hydrogel systems for providing improved properties for certain medical applications are described. The hydrogel systems are effective for forming a space filling hydrogel in a body cavity and for the prevention of adhesion formation between tissues within the body cavity following a surgical procedure. Hydrogel delivery systems for transcervical delivery of a premixed precursor solution and an accelerator solution are described. Methods for transcervical installation of intrauterine hydrogels with distended fill are also described. The hydrogel systems, hydrogel delivery systems, and associated methods can be useful for providing degradable hydrogel in the uterine cavity, including the cervical canal, for the prevention of adhesions following intrauterine procedures.

Abstract: A therapy needle is provided that may include any of a number of features. One feature of the therapy needle is that it can apply microwave energy to tissue to produce a coagulative spherical volumetric ablation of the tissue. In some embodiments, the volumetric ablation can have a diameter ranging from 1 cm to 4 cm and can be formed in less than 3 minutes. Another feature of the therapy needle is that it can utilize an electric cutting device on a distal portion of the needle to cut a hole in high density tissue. Methods associated with use of the therapy needle are also covered.

Abstract: A probe (1) is designed to propagate and radiate microwave electromagnetic energy in a controlled fashion. The probe (1) includes at least one waveguide (2) of cross-section which would not normally pass microwaves at the operational frequency. The waveguide (2) therefore includes dielectric material (5), such as alumina, in the form of a rod an exposed portion of which forms an antenna. The probe is preferably for use in endometrial ablation and therefore the reduced dimension of the waveguide can be made compatible with the narrow neck of the uterus.
