A trocar assembly and method for uterine and fetal surgeries includes a cannula defining a hollow tubular sleeve that extends from a first open end to a second open end, a hollow obturator defining a shaft that extends from a first open end that is tapered to a second open end, wherein the hollow obturator is located within the cannula, and wherein the trocar assembly is configured to be inserted into a patient's body to give access to a bodily cavity, such as the amniotic cavity or the fetus. The trocar assembly is configured for insertion into the amniotic cavity using the Seldinger technique.

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

A method for treating target tissue comprises introducing a portion of a surgical device into a patient, the surgical device having a treatment end, positioning the treatment end of the surgical device adjacent to the target tissue, and administering a devascularizing material to the target tissue. The devascularizing material, after a time period, is able to devascularize the target tissue. A surgical device comprises a shaft extending between proximal and distal portions, a treatment end located at the distal portion, where the treatment end administers the devascularizating material to a target tissue.

The invention pertains to an echolucent image enhancing hydrophobic, water-immiscible composition, wherein the composition turns echogenic when foamed with air or gas bubbles formed from mechanically inserting (i) air or gas; or (ii) aqueous solution with air or gas into the hydrophobic, water-immiscible composition. The invention also pertains to a foamed echogenic image enhancing hydrophobic, water-immiscible composition and optionally comprising aqueous solution forming a single-phase, said composition comprising air or gas bubbles retained in the composition, and wherein the volume ratio of aqueous solution:hydrophobic, water-immiscible composition is preferably in the range of between 0:100 (i.e. no aqueous solution) and 75:25, preferably between 0:100 and 60:40.

Provided is a medical device with portions configured for fitting and being retained simultaneously into two cavities on opposite sides of the body of a subject, for example the eustachian tubes or the fallopian tubes. The device may include an elongated member with a central segment and first and second peripheral segments extending therefrom. These segments differ in their intended function and eventual in situ positioning: the two peripheral segments intended for insertion and positioning within the two cavities and exerting their function within the cavities. The central segment serves as a link between two peripheral segments and may also be used for some other functions by its position. The elongated member may have elastic properties.

The present disclosure relates to systems and methods for cell collection within a vessel. The systems and methods can include a cannula having with a pathway extending between a first end and a second end of the cannula and a first lumen situated longitudinally within the pathway of the cannula. The systems and methods can also include an inverted balloon situated within the first lumen, the balloon being coupled at one end to the second end of the cannula and coupled at an opposing end to a rod to permit controlled eversion. In the presence of positive pressure along a defined path diverging from an axis of the pathway the balloon, along with an inverted sleeve situated within the balloon, can evert along the defined path from within the cannula.
