Abstract: 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.

Abstract: A charger for charging a plurality of pressure sensing catheters is provided. The charger has a plurality of charging ports of which a first charging port and a second charging port receives a first connector and a second connector respectively. The first and second connectors each have a first and second radiofrequency identification tags respectively, having information indicative of identifiable information of a first and second pressure sensing catheters respectively. The charger has a plurality of antennas, of which a first antenna and a second antenna can be positioned proximate to the first charging port, and second charging port respectively. When the first connector is inserted into the first charging port, the first radiofrequency identification tag is guided to a predetermined orientation with respect to the first antenna to minimize a spacing therebetween, and to maximize absorption of radiofrequency energy therebetween.

Abstract: A multi-lumen catheter for monitoring intramuscular pressure having an elongated body configured and dimensioned for insertion into a compartment of a patient. The catheter has a pressure sensor to determine if excessive pressure is being applied. A sensor is in communication with the lumen to continuously measure pressure to provide continuous readings of intramuscular pressure.

Abstract: Systems and methods for measuring phase dynamics and other properties (e.g. intracranial pressure) are disclosed. For example, the system may generate a reference waveform and a measurement waveform using digital synthesizers, each waveform having an identical constant frequency but also a relative phase shift. Next, system may send a tone-burst, via a transducer, into a sample (e.g. a skull or a bonded material), and then receive a reflected tone-burst in response. Then, a phase difference between the received tone-burst and the measurement waveform may be determined with a linear phase detector. Next, the phase shift of the measurement waveform may be adjusted, by the determined phase difference, such that there is no longer any phase difference between the received tone-burst and the adjusted measurement waveform generated by the appropriate digital synthesizer. A similar adjustment may occur after subsequent tone-bursts, allowing accurate monitoring of continuously variable phase relationships.

Abstract: An intra vaginal device (10) including an elongated hollow body (11) with side wall portions (15, 16 and 24). Secured to each wall portion (15 and 24) is a sensor (19), while secured to the wall portion (16) is a sensor (20). The sensors (19) simply measure forces directly applied by the bi-lateral contraction of the pubococcygeus, while the sensor (20) provides an indication of the puborectalis contraction forces.

Abstract: Non-invasive measurement of intracranial pressure (ICP), for example mean ICP. A probe adjacent the head emits energy, such as ultrasound, and receives reflected signals. A processing unit derives ICP waveform from the signals. A pressure mechanism applies external pressure intermittently to outer surface of the head and incrementally increases the external pressure. The processing unit is configured to detect a decrease in amplitude of the ICP waveform (occurring in some embodiments only after an intermediate period of ICRS compensation), the processing unit configured to determine the ICP of the person from a sum of applied external pressures from a time of the initial value A1 until a final value at which the amplitude remains stable with additional increase in applied external pressure. In some cases, the final value is earlier than that but the processing unit extrapolates the sum to when the amplitude remains stable with additional increases in pressure.

Abstract: It has been discovered that even mild changes in cerebrospinal fluid (CSF) pressure or intracranial pressure (ICP) can be detected immediately as evidenced by distortions in the ONS surface structure. Further, the changes in the ONS persist after the CSF pressure has returned to normal. The stability of ONS distortions provides a means of detecting transient changes in brain pressure even when the use of the diagnostic ultrasound is delayed. One embodiment provides systems and methods for detecting or diagnosing brain injury by detecting distortions or deformations of the ONS, preferably using ultrasound.
