The invention discloses a clamp for fallopian tube recanalization under a laparoscope, aiming to solve the technical problem on simply, efficiently and safety completing a hydrotubation test, salpingorrhaphy or an operation for cornual implantation of the fallopian tube under the laparoscope. The clamp for fallopian tube recanalization under the laparoscope is provided with a main tube, the front end of the main tube is connected with an openable clamp blade assembly, the rear end of the main tube is connected with a handle, the main tube is internally provided with a pull tube, the front end of the pull tube is articulated with the clamp blade assembly, the handle controls the rear end of the pull tube to enable the main tube to move back and forth, a guide tube penetrates through the pull tube and the clamp blade assembly, and the rear end of the guide tube is connected with a needle head of a syringe. Compared with the prior art, in the invention, by means of the clamp blade assembly and the pull tube for controlling the opening of clamp blades, the pull tube inside the clamp blade assembly ensures that the guide tube can directly enter the interior of the fallopian tube, the rear end of the guide tube is connected with the syringe for carrying out the hydrotubation test, and the guide tube is used as the internal stent for the fallopian tube so as to be beneficial to fallopian tube anastomosis and cornel cornual implantation of the fallopian tube, so that the technical level is improved and operation time and operation cost are saved.

The Vas Deferens or Fallopian tubes valve system incorporates a small valve in line with either the Vas Deferens or the Fallopian tube in order to open or close fluid communication therein, and effectively a form of birth control. The valve is installed on either one of the Fallopian tubes or Vas Deferens, and is manually or remotely controlled. The small valve is manually controlled via an arm that can be manually rotated to open or close the valve seated there under. A magnetic version of the small valve incorporates magnets on the arm in order to induce motion of the arm upon focusing a magnetic field upon the valve. A remotely operable valve utilizes a solenoid and radio receiver to remotely operate the small valve.

The invention discloses a preparation method and an application of a tissue slice for observing temporal-spatial distribution of early embryo development in vivo. The preparation method comprises the following steps that 4% paraformaldehyde fixing, upward gradient ethanol dehydration, wax dipping, embedding, serial section, baking, dewaxing and downward gradient ethanol rehydration are performed in sequence on oviducts or uterine tissues which contain mice embryos in every period, and finally, after haematoxylin-eosin staining is performed on the tissues in the slice, neutral gum is used for sealing the slice, or after immunofluorescence histochemical staining is performed on the slice, a fluorescence resistant quenching sealing agent is used for sealing the slice. The tissue slice disclosed by the invention can be used for manufacturing a map of early mice embryo development and detecting the expression of Crb3 in the mice embryos in every period of development in vivo. The preparation method has the advantages that positions of all organs in the embryos can be relatively fixed, so that the position change of embryo cells in a genital tract and the continuity of embryo development can be conveniently observed, the structure is clear, and the tissue slice is convenient to store.

The present invention provides a method for inducing Fallopian tube blockage as a means for female contraception. The method comprises contacting the inner surface tissue of a Fallopian tube with a silver nitrate bearing substrate, delivering an amount of silver nitrate to the tissue sufficient to induce blockage of the Fallopian tube. Preferably, the substrate is a bead. In one embodiment, at least one silver nitrate bearing bead is introduced through the uterine opening of the Fallopian tube by use of a catheter or other device suitable for manipulating the bead. Alternatively, a plurality of beads can be introduced into the Fallopian tube. In a preferred embodiment, one or more silver nitrate bearing beads are arranged on a string to facilitate later removal of the beads. The method of the present invention delivers an amount of silver nitrate to the tissue sufficient to cause tissue necrosis and blockage of the Fallopian tube. The silver nitrate is delivered to the tissue by the substrate in a controlled and localized manner.

A non-invasive method for the diagnosis of adenocarcinoma or precursor lesions in a female subject and a kit for performing such diagnosis are provided. The method comprises the steps of (1) preparing epithelial cells of a sample of the subject obtained from a rinse of the uterine cavity and, optionally, the fallopian tubes, and (2) performing an analysis of the cells to determine an abnormality associated with ovarian or endometrial cancer, where the abnormality is indicative of adenocarcinoma or a precursor lesion.

The invention discloses a hysterosalpingography tube. The hysterosalpingography tube comprises a soft tube, a conical head for closing the outer opening of the cervix, two fixing clamps for clamping the cervix, and a fallopian tube interventional catheter for directedly inputting the contrast liquid to the fallopian tube; one end of the soft tube is weave through with the conical head and is formed with a balloon which is inflated or filled with liquid to close the inner cavity of the cervix; the soft tube forms a guide channel for penetrating the fallopian tube interventional catheter and a filling channel for inflating or filling the balloon; two fixing clamps are respectively connected to two sides of the conical head; the conical head is formed with a slot; the fixing clamp comprises an inner clamping arm, an outer clamping arm and a spring piece; the end of rotating connection end of the inner clamping arm formed by the inner clamping arm and the outer clamping arm form is inserted in the slot; the other end of the inner clamping arm forms operating forceps, one of the two clamping rods is inserted in a first slot. The hysterosalpingography tube has the advantages of high reliability and small influence on contrast imaging.

A device is provided to confirm intratubal occlusion in a subject of a fallopian tube having an inner diameter that includes a tubular shaft having a distal end and an interior lumen. An examination head is joined to the distal end of the shaft. A visualization modality in the examination head provides visual or acoustic imaging of the fallopian tube. A power source for the visualization modality is provided. A handle is provided for control of the device. An ex vivo imager of an ocular, video headgear, or a video display is provided in communication with the visualization modality. A process for evaluating an intratubal implant in a fallopian tube through optical or sonic wave visualization is also provided.

A method, apparatus, and kit for marking the opening between the fallopian tube and the uterus (tubal ostia) are provided. A marking dye provided in a marking assembly including a fluid dispenser coupled to a catheter having an open end and a guide wire. The catheter is inserted into the uterus and to a position adjacent the tubal ostia. When properly inserted, the fluid dispenser is activated to cause fluid to flow through the catheter and to the wall of the uterus to provide a mark. Once the mark is provided, endometrial ablation process can be provided in the uterus. The marks can then be used to guide the insertion of tubal occlusion devices.
