Apparatus and processes for use in a narrow body lumen are provided. Apparatus may include an outer shaft portion; a tube receivable within the outer shaft portion; and an elongate inflatable body having first and second ends, the first end being sealed to the outer shaft portion and the second end being sealed to the tube. In an initial configuration, the elongate inflatable body is received in the outer shaft portion. The tube is slidable relative to the outer shaft portion to evert the elongate inflatable body when the elongate inflatable body moves out of the outer shaft portion.

A system and a method for assessing the ovarian reserve function of a subject. The system for assessing a subject's ovarian reserve function comprises: a data acquisition module configured to acquire data of the subject's age, anti-Müllerian hormone (AMH) level, follicle stimulating hormone (FSH) level, and antral follicle count (AFC); and an ovarian reserve function calculation module configured to calculate the above-mentioned information acquired in the data acquisition module, so as to work out the subject's probability of poor ovarian response (p). Further, the population is divided into four groups according to the interaction relationship between the predicted probability of poor ovarian response and the dose of ovulation stimulants, so as to divide the population with similar ovarian responses into one group.

A method and system of providing therapy to a patient's uterus is provided, which can include any number of features. The method can include the steps of inserting a uterine device into the uterus and performing a uterine integrity test to determine that the uterus is intact and not perforated. Systems for performing these methods with monitored flow rate and independent of patient height relative to the pressure source are also disclosed.

A direct-vision abortion uterine curettage device and a direct-vision abortion uterine curettage system are provided. The direct-vision abortion uterine curettage device includes a uterine curettage mechanism, an observation mechanism, a circuit, a negative pressure suction mechanism and an operating rod. A diagnostic curette of the uterine curettage mechanism is arranged at front ends of the operating rod and a camera and is in a visual field of the camera. The camera being mounted at the rear may guarantee that the diagnostic curette is completely within a range of the visual field of the camera, so that an operation procedure may be fully visible without any observation blind areas. Meanwhile, there will be no operation blind spots due to the diagnostic curette being blocked by a height of a lens module itself The direct-vision abortion uterine curettage system can perform surgical operations under real-time display of a display system.

The present invention provides a uterus OCT catheter, comprising: a catheter body; the catheter body comprises an outer sleeve, an OCT imaging catheter and a Luer connector; the outer sleeve is provided with an exit window; the reflecting surface of the reflecting prism in the OCT imaging catheter faces the exit window. The present invention further provides a uterus OCT equipment with pull-back function, comprising a pull-back device and the catheter body, the pull-back device comprises a first housing, a driving connector, a fixing sleeve and a catheter fixing tube. The invention adopts the way that the outer sleeve wraps the OCT imaging catheter to increase the overall strength and diameter; a pull-back device is adopted, the pull-back process is stable and in uniform speed, and can effectively prevent complications during human operation and damage to human tissue during pull-back process.

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-cervical 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.

The present disclosure describes ultrasound imaging systems and methods configured to identify ovarian follicles by applying a neural network to pre-processed ultrasound image frames. Systems may include an ultrasound transducer configured to acquire echo signals responsive to ultrasound pulses transmitted toward a target region. One or more processors communicatively coupled with the ultrasound transducer may be configured to generate at least one image from the ultrasound echoes. A threshold may be applied to the image frame that differentiates pixels representative of an ovarian follicle present in the target region from other subject matter. The processors may apply a neural network to the thresholded image frame, in which the neural network determines the presence of the ovarian follicle in the thresholded image frame. The processors also may generate an indicator based on the presence of the ovarian follicle and display the indicator on a user interface.

A method and system of providing therapy to a patient's uterus is provided, which can include any number of features. The method can include the steps of inserting a uterine device into the uterus and performing a uterine integrity test to determine that the uterus is intact and not perforated. If it is determined that the uterus is not perforated, a patency test can be performed to determine that the uterine device is not clogged or embedded in tissue. If the uterus is intact and the device is not clogged or embedded in tissue, the uterus can be treated with the uterine device, e.g., uterine ablation. Systems for performing these methods are also disclosed.

Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO.sub.2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.
