Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.

A falloposcope intended for use with a hysteroscope to access, image, and collect samples from a patient's fallopian tube includes a cannula having an angled tip oriented to engage a fallopian tube os when the cannula is transcervically introduced to a patient's uterus through the hysteroscope. The catheter has a distal viewing tip configured to be advanced from a distal end of the cannula into the patient's uterus through a cervical os. A viewing chamber has a wide proximal end attached to the distal viewing tip of the catheter, and the viewing chamber is at least partially transparent and typically tapers in a distal direction to provide a clear viewing zone for the endoscope as well as atraumatic advancement into the fallopian tube.

Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.

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.

Apparatus for delivering a therapeutic agent to a uterine cavity including an elongated member having a fluid channel for passage of the therapeutic agent into the uterine cavity, a dispensing member extending distally of the elongated member and having at least one perforation for passage of the therapeutic agent into the uterine cavity into contact with the endometrium. An infusion line is in communication with the fluid channel for passage of a fluid into the uterine cavity to assess leakage to determine integrity of the uterine cavity prior to passage of the therapeutic agent into the uterine cavity.

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 generally relates to devices, systems, and methods for Fallopian tube diagnostics. In some embodiments, a tube may have a distal end, and a balloon may be coupled to the distal end of the tube. The balloon may be disposed in the tube in a first, inverted position and movable to a second, everted position. The balloon may be extendable a distance distal of the tube distal end such that a surface of the balloon is contactable with an inner surface of the Fallopian tube. A push wire may have a distal end coupled to a second end of the balloon. The balloon may be movable from the first inverted position to the second everted position by actuation of the push wire. The surface of the balloon may include a plurality of surface features for collection of a tissue sample of the inner surface of the Fallopian tube.

A trocar assembly 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 uterine cavity (amniotic cavity) or the fetus. The trocar assembly is configured for insertion into the uterine cavity using the Seldinger technique.
