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.

The invention is generally a system, apparatus, and method for monitoring and measuring a change in intrauterine pressure without rupturing the amniotic sac. A catheter is coupled to a pressure sensing module. The pressure sensing module is configured with a chamber that is in fluid communication with a balloon of the catheter. The chamber includes a pressure-sensing membrane coupled to sensing circuitry. The sensing circuitry is configured to detect a pressure applied to the pressure-sensing membrane and communicate the condition to a monitor of the system. Methods include inserting the catheter through the cervix so that the balloon may be inflated and situated in the lower segment of the uterus, resting against the amniotic sac. Because the balloon of the catheter is in fluid communication with the pressure-sensing membrane, pulsations of the amniotic sac will be sensed by the sensing circuitry of the pressure sensing module.

A monitoring system is described which comprises a sensor device for generating sensor data, the sensor device having a secondary coil, and a receiver device having a controller, and a primary coil for wirelessly communicating with the sensor device, the receiver device being operable to wirelessly charge the sensor device via inductive coupling between the primary and secondary coils. A quality factor of the primary coil is controllable, and the controller is operable to control the quality factor of the primary coil to be higher when the receiver device is wirelessly charging the sensor device than when the receiver device is receiving sensor data from the sensor device. As a result, the same coil can be used both for efficient power transfer (wireless charging) by using the coil in a (relatively) high quality factor mode, and for reliable data communications by using the coil in a (relatively) low quality factor mode.

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 system for in-vivo monitoring of pressure of a body fluid. The system comprises a delivery component and an elongate sensor delivery member shaped so as to pass through the delivery component when it has been inserted in to a patient. A first pressure sensor is positioned at a distal end of the delivery member.

In one example, the disclosure relates to a catheter system comprising an elongated body defining a lumen where the elongated body comprises a proximal portion and a distal portion. An anchoring member may be positioned on the proximal portion of the elongated body. The system further comprising at least one sensor configured to be coupled to the elongated body where the at least one sensor may be configured to sense one or more parameters of a fluid within the lumen of the elongate body. Memory configured to be coupled to the elongated body where the memory may be configured to store sensor calibration information. The system configured to calibrate the at least one sensor based on the sensor calibration information stored by the memory.

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.

Systems and methods for adaptive, multi-resolution magnetic resonance imaging (“MRI”), in which an MRI scan prescription is adaptively changed to acquire high-quality data from select regions-of-interest (“ROI”) in a larger field-of-view (“FOV”), are provided. The higher quality data can include data representing higher spatial resolution, higher signal-to-noise ratio (“SNR”), increased diffusion encoding via repeated acquisition with a larger number of diffusion-encoding directions, and so on. A composite image can be generated that displays the higher quality images of the ROIs overlaid on the larger FOV.

A system for augmenting uterine forces includes a medical apparatus having a balloon body that transitions between a compacted state and an expanded state, a catheter that receives the medical apparatus and obtains electrical signals indicative of intrinsic uterine contractions, and a controller coupled to the catheter to receive the electrical signals, and to a source of an agent. The controller processes the electrical signals to detect an onset of an intrinsic uterine contraction, an increase in uterine contraction forces, or a decrease in uterine contraction forces. In response to a detection of an onset of an intrinsic uterine contraction or an increase in uterine contraction forces, the controller causes an agent to be delivered from the agent source to the balloon body to expand the balloon body. In response to a detection of a decrease in uterine contraction forces, the controller causes agent to discharge from the balloon body to collapse the balloon body.
