Devices and methods for vascular navigation, assessment and/or diagnosis are disclosed where a location detection system generally includes an elongate body defining a lumen at least partially along a length of the elongate body. One or more sensors are positioned near or at a distal tip of the elongate body and one or more openings are defined along the elongate body in proximity to the one or more sensors. The one or more openings are configured to control a boundary distance between the one or more sensors and a fluid with a parameter of a known initial value when emitted from the one or more openings. A controller is in communication with the one or more sensors and is configured to track a change in the parameter relating to concentration over the one or more sensors and determine a position of the one or more sensors within a body.

Devices and methods for vascular navigation, assessment and/or diagnosis

Foley type catheter embodiments for sensing physiologic data from a urinary tract of a patient are disclosed. The system includes the catheter and a data processing apparatus and methods for sensing physiologic data from the urinary tract. Embodiments may also include a pressure sensor having a pressure interface at a distal end of the catheter, a pressure transducer at a proximal end, and a fluid column disposed between the pressure interface and transducer. When the distal end is residing in the bladder, the pressure transducer can transduce pressure impinging on it into a chronological pressure profile, which can be processed by the data processing apparatus into one or more distinct physiologic pressure profiles, for example, peritoneal pressure, respiratory rate, and cardiac rate. At a sufficiently high data-sampling rate, these physiologic data may further include relative pulmonary tidal volume, cardiac output, relative cardiac output, and absolute cardiac stroke volume.

Method of monitoring health status of a patient

Methods and apparatus for guiding medical care based on sensor data from the gastrointestinal tract are described utilizing an apparatus which can be used with enteral feeding. Generally, the apparatus includes an elongated body having a length configured for insertion into a stomach and at least one pair of electrodes located along the length of the elongated body and positionable for placement within the stomach. A controller in electrical communication with the at least one pair of electrodes is included and the control may also be configured to measure a conductivity or impedance between the pair of electrodes and to determine a gastric residual volume of the stomach based on the measured conductivity or impedance.

Methods and apparatus for guiding medical care based on sensor data from the gastrointestinal tract

Devices and methods for vascular navigation, assessment and/or diagnosis are described which determine the location of the tip of a vascular catheter using the introduction of a medium with a measurable parameter (e.g., temperature, light reflection, sound reflection, etc.) and sensing and measuring the measurable parameter as the catheter is advanced. Measurements of the parameter are tracked over time, recorded and analyzed. The value of the parameter and/or the shape of the parameter value vs. time curve may be used in the analysis. For example, curve amplitude, variability, standard deviation, slope, etc. may be used in the analysis of catheter location.

Liners for cryogenic treatment systems are described where a cryogenic fluid or gas may be introduced into a liner expanded within a body lumen such as the uterine cavity. The liner may be intentionally sized to be substantially larger than the typical size of the uterine cavity, e.g., 1.2 times (or more), greater than the size of the uterine cavity into which the liner is inserted. Because the liner is sized intentionally larger than the body lumen to be treated, the liner may never fully expand when deployed. But even with folds or portions of the liner being folded upon itself, the liner may remain sufficiently supple such that the resulting uncontrolled folds allow for complete conformance of the liner against the anatomy of the contacted tissue.

Liner for cryogenic treatment systems

A wearable apparatus for the treatment or prevention of osteopenia or osteoporosis, stimulating bone growth, preserving or improving bone mineral density, and inhibiting adipogenesis is disclosed where the apparatus may generally comprise one or more vibrating elements configured for imparting repeated mechanical loads to the hip, femur, and/or spine of an individual at a frequency and acceleration sufficient for therapeutic effect. These vibrating elements may be secured to the upper body of an individual via one or more respective securing mechanisms, where the securing mechanisms are configured to position the one or more vibrating elements in a direction lateral to the individual, and the position, tension, and efficacy of these vibrating elements may be monitored and/or regulated by one or more accelerometers.

Wearable apparatus for the treatment or prevention of osteopenia and osteoporosis

The disclosure describes devices and methods for providing transdermal electrical stimulation therapy to a subject including positioning a stimulator electrode over a glabrous skin surface overlying a palm of the subject and delivering electrical stimulation via a pulse generator transdermally through the glabrous skin surface and to a target nerve or tissue within the hand to stimulate the target nerve or tissue within the hand so that pain felt by the subject is mitigated. The pulses generated during the electrical stimulation therapy may include pulses of two different magnitudes.

Method and apparatus for transdermal stimulation over the palmar and plantar surfaces

Systems, devices and methods for draining and analyzing bodily fluids and assessing health are described and generally comprise a drainage tube in fluid communication with at least one opening near or at a distal end of a catheter, a pump in fluid communication with the drainage tube and configured to apply a negative pressure to the drainage tube, and a valve configured for unidirectional flow and in fluid communication with the drainage tube. A controller is configured to actuate the pump to apply the negative pressure for clearing an airlock and to monitor a urine output from the patient over a first predetermined period of time above a urine output threshold and over a second predetermined period of time below the urine output threshold. The controller may determine a risk of acute kidney injury if the urine output below the urine output threshold exceeds the second predetermined period of time.

Systems, devices and methods for draining and analyzing bodily fluids and assessing health

Devices and methods to measure gastric residual volume (GRV) are described where at least one additive component (a GRV indicator) may be dispersed in a body lumen such as a stomach. The GRV indicator may changes a physical (chemical, electrical, thermal, mechanical, optical, etc.) characteristic within the stomach by a measureable degree. This degree of change and/or the rate of return to the previous state, may be used to determine the GRV of a patient. The determined GRV can also be used to automatically or semi-automatically control the patient's feeding rate and/or volume and/or frequency to adequately nourish the patient but avoid complications. The physical characteristic(s) may also be used to detect that the feeding catheter or tube is in the correct location (ie stomach vs lung or esophagus.

Devices and methods to measure gastric residual volume

In certain variations, systems and/or methods for electromagnetic induction therapy are provided. One or more ergonomic or body contoured applicators may be included. The applicators include one or more conductive coils configured to generate an electromagnetic or magnetic field focused on a target nerve, muscle or other body tissues positioned in proximity to the coil. One or more sensors may be utilized to detect stimulation and to provide feedback about the efficacy of the applied electromagnetic induction therapy. A controller may be adjustable to vary a current through a coil to adjust the magnetic field focused upon the target nerve, muscle or other body tissues based on the feedback provide by a sensor or by a patient. In certain systems or methods, pulsed magnetic fields may be intermittently applied to a target nerve, muscle or tissue without causing habituation.

Methods and devices for performing electrical stimulation to treat dysmenorrhea or menstrual cramps

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.
