There is provided a cervical canal dilator device having a hollow shaft having proximal and distal ends. The shaft is covered on an end portion of the distal end by a slidable protective sleeve. There is at least one inflatable dilating balloon formed on the distal end of the shaft. There is at least one tube extending internally along the shaft and connected to the at least one balloon for inflation thereof, the tube having a connection port on the proximal end of the shaft. A camera is situated at the tip of the distal end of the shaft and a plurality of ejection orifices are formed on the shaft, adjacent to the camera, and anywhere else along it. The shaft is inserted into a patient's cervical canal while viewing the canal via the camera for guidance, and safe and easy placement of the hollow shaft during the insertion, and where the at least one balloon is inflated by introducing a substance via the connection port, the inflated balloon causing dilation of the cervical canal, the shaft being removed from the patient when the cervical canal is dilated.

Provided is a balloon unit for uterine hemostasis capable of reliably suppressing or stopping uterine bleeding. The balloon unit includes a flexible tube and a balloon provided in a distal end portion of the tube. The balloon has a lower uterine lumen compression portion that compresses an inner surface of a lower uterine lumen and an upper uterine lumen compression portion that compresses an inner surface of an upper uterine lumen. As the balloon, two balloons including a first balloon functioning as the lower uterine lumen compression portion and a second balloon functioning as the upper uterine lumen compression portion are provided.

In various embodiments of the invention, a manipulator attaches to and allows a sheath to be positioned inside the cervix and a catheter to thereby be inserted through the sheath and be positioned in a desired location in the uterus. In various embodiments of the invention, the manipulator may be attached or permanently connected to the sheath. In various embodiments of the invention, the sheath is fenestrated to allow the catheter to be detached from the sheath. In various embodiments of the invention, the manipulator allows the sheath to be positioned through the cervix canal to allow for catheter transmitted intrauterine pressure monitoring or balloon catheter assisted ripening of the cervix.

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.

A manifold for collecting a tissue sample with a medical waste collection assembly. A base portion of a housing is removably engaged with a manifold receiver to provide a suction path from an inlet fitting receiving a suction line. A tray may be removably positioned within an accessory sleeve. Locating features facilitate defining a gap between a base portion of the tray and a lower barrier of the accessory sleeve. The tray may include a control surface to move the manifold between a sealing configuration, and a bleed configuration in which a second suction path is provided through the gap and below the tray. A backflow prevention valve may be disposed within the suction path between the tray and a filter element. Methods for collecting the tissue sample are also disclosed.

An occlusion device includes a body having a plurality of layers and defining a first diameter. Each layer of the plurality of layers is releasably coupled to a respective inwardly-adjacent layer. An outermost layer of the plurality of layers is removable from the respective inwardly-adjacent layer. Removal of the outermost layer reduces an outer diameter of the body from the first diameter to a second diameter that is less than the first diameter.

A collection system for collecting outflow from a hysteroscopic surgical procedure includes a plurality of collection vessels each including a flexible body defining an internal volume and transitionable between a collapsed configuration and an expanded configuration. The collection system further includes connection tubing coupling adjacent collection vessels with one another, outflow tubing coupled to at least one of the collection vessels, and a plurality of retention canisters. Each retention canister includes a rigid body. Each collection vessel is configured to engage a corresponding retention canister such that each rigid body at least partially receives one of the flexible bodies therein.

An everting balloon system is disclosed that can be used for biopsy within a body of a patient or animal. The everting balloon system can be used to access a bodily cavity or vessel for tissue specimen collection at specific bodily locations. The everting catheter system described simplifies the process of tissue biopsy.

Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure sensing elements which may allow for control of the pressure within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled or room temperature fluid such as water may then be used to rapidly terminate the treatment session.

A process for recovering one or more blastocysts from a uterus of a human includes a step of placing a device transvaginally into a cervical canal of the patient; a step of delivering fluid through the device to the uterus and applying a vacuum to a uterus of the patient to aspirate fluid and entrained one or more blastocysts from the uterus; and a step of performing a biopsy procedure on the one or more recovered blastocysts to remove one or more of trophectoderm cells or inner cell mass from the recovered blastocysts. The process may further include a step of storing one or more of the biopsied trophectoderm cells or inner cell mass following the biopsy procedure and a step of performing at least one molecular diagnostic assay test on the one or more of the biopsied trophectoderm cells or inner cell mass.
