  • Patent number: 10213151
    Abstract: A system for accessing a patient's uterine cavity and detecting perforations in the uterus includes an elongated probe having a flow channel extending to a terminal outlet in a distal region of the probe. A fluid source is coupled to the flow channel, and a seal on the probe is positionable in an endocervical canal. The probe may be trans-cervically inserted into the uterine cavity, and a fluid may be introduced through the channel to flow outwardly from the terminal outlet into the uterine cavity. A parameter of said fluid flow is monitored to detect a perforation in the uterus.

  • Patent number: 10195325
    Abstract: There is provided a method for controlling a flow of sperms in a uterine tube formed by a uterine tube wall of a patient. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the uterine tube wall) at least one portion of the uterine tube wall to influence the flow of sperms in the uterine tube, and stimulating the constricted wall portion to cause contraction of the uterine tube wall portion to further influence the flow of sperms in the uterine tube. The method can be used for restricting or stopping the flow of sperms in the uterine tube, or for actively moving the fluid in the uterine tube, with a low risk of injuring the uterine tube.

  • Patent number: 10188426
    Abstract: An embryo transfer catheter (10) is described comprising an outer catheter body (12) having first and second lumens (14, 16). The second lumen (16) is adapted to receive an internal catheter (not shown) with a single lumen which, in use, will allow passage of an embryo or embryo-containing cannula (not shown) into the uterus (18) of the recipient. An inflatable balloon (20) is provided at a distal end of the first lumen (14). The inflatable balloon (20) is designed to be as small as possible in its inflated condition while still being retained in the uterus (18). The shape of the balloon (20) is adapted in its inflated state to conform to just the lowest part of the uterus (18). The aim in designing the balloon (20) as small as possible is to leave as much endometrium accessible to the embryo for implantation as possible, and to occupy as little volume as possible within the uterine cavity and to exert as little pressure as possible to avoid causing contractions, while still being retained in the uterus (18).

  • Publication number: 20140216465
    Abstract: Contraceptive methods, systems, and devices generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. The contraceptive device may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues, by manipulating one or more actuators of a proximal handle with a single hand. This leaves the other hand free to manipulate a hysteroscope, minimizing the number of health care professional required to deploy the contraceptive device.

  • Patent number: 8733360
    Abstract: The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization s effected by passing a current through there resilient structure to the tubal walls.

  • Patent number: 8726906
    Abstract: The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of elements for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable or degradable material that supports tissue ingrowth or wound healing or a similar response that replaces the cured occlusive material leaving little or no original occlusive material in place. The delivery system is positioned to allow for placement of the occlusive material into the body conduit. Use of delivery systems, methods and devices for re-opening an occluded body conduit are also included.

  • Patent number: 8707957
    Abstract: A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug.
