A method for treating a spine comprises the steps of: inserting a surgical instrument into a tissue cavity, the surgical instrument including an image guide oriented relative to a sensor to communicate a signal representative of a position of the surgical instrument relative to the tissue cavity; displaying a selected configuration with a distal end of the surgical instrument in the tissue cavity; tracking movement of the selected configuration in the tissue cavity with a tracking device that communicates with a processor to generate data for display of the movement; and determining a volume of the tissue cavity based on the data. Systems, spinal constructs, implants and surgical instruments are disclosed.

Methods and apparatus for treating disorders of the ear, nose, throat or paranasal sinuses, including methods and apparatus for dilating ostia, passageways and other anatomical structures, endoscopic methods and apparatus for endoscopic visualization of structures within the ear, nose, throat or paranasal sinuses, navigation devices for use in conjunction with image guidance or navigation system and hand held devices having pistol type grips and other handpieces.

A method is provided for reducing the risk of sustaining a traumatic brain injury caused by a traumatic event that includes identifying a subject at risk of sustaining a traumatic brain injury, and then precisely increasing the partial pressure of carbon-dioxide (CO.sub.2) in the blood of the subject (pCO.sub.2). This method can be applied to raise the CO.sub.2 and pCO.sub.2 to improve orthostatic hypotension in conditions such as dysautonomias (like Positional Orthostatic Tachycardic Syndrome POTS) and to facilitate the drive to breathe in conditions like Central Sleep Apnea (CSA) and Sudden Infant Death Syndrome (SIDS). The pCO.sub.2 of the person is increased by placing a breathing apparatus over the mouth of the person through which the person must breath, wherein the breathing apparatus includes an enlarged dead space volume in which expired CO.sub.2 collects to be inhaled or re-breathed by the person on the next inhalation.

A device for estimating breast implant volume is provided, which may include an input interface and a processing circuit. A numerical value may be inputted in to the input interface. The processing circuit may calculate the estimation value of breast implant volume according to a linear model and the numerical value. The processing circuit may multiply the numerical value by a coefficient to generate a product, and add a constant to the product to generate the estimation value of breast implant volume, wherein the numerical value may be a breast sample weight or a breast size.

A medical device may include a handle assembly having an actuator and a sheath. The sheath may extend between a proximal end and a distal end. The proximal end of the sheath may be coupled with the actuator. The medical device may further include an end-effector moveable relative to the sheath between an extended configuration and a retracted configuration. The end-effector may include a plurality of expandable legs. Each of the plurality of expandable legs may include a plurality of first indicia and a plurality of second indicia. A color of each of the first plurality of indicia may be different than a color of each of the second plurality of indicia.

A catheter devices/systems and methods therefrom are described herein for treating acute kidney injury, especially the contrast-induced acute kidney injury wherein the devices may prevent the contrast dyes from entering into kidney and/or facilitate blood flow of kidney by said catheter system.

A system for identifying a size doubling number of a lesion, having: a ruler with a planar surface defining a data portion that includes data zones, including: a first zone defining first zone arcs distributed in a concentric configuration, the first zone arcs defining first mutually unique radii, ranging from a first minimum radius to a first maximum radius; the first zone includes first zone size markers, positioned adjacent ones of the first zone arcs, and the first zone size markers identify the size doubling number of the clinical lesion having a size corresponding to a respective one of the first zone arcs, the size doubling number representing one or more of volume, area and radius doubling of the lesion; a slider sliding along the ruler, a caliper that moves with the slider, and a smart device receiving data, from the caliper, indicative of a size of the clinical lesion.

A system for controlling a pressure inside a bladder through an endoscope, where the distal end portion of the endoscope is located inside the bladder and the endoscope has an inlet port through which fluid to enter the bladder and an outlet port through which fluid in the bladder to exit the bladder. The system includes one or more processors that receive a first signal from a first pressure sensor installed in a first fluid passageway that is in fluid communication with the inlet port; receives a second signal from a second pressure sensor installed in a second fluid passageway that is in fluid communication with the outlet port; and based on at least one of the first and second signals, actuates a valve installed in the first fluid passageway of fluid so as to adjust the flow rate into the bladder through the inlet port.

A fluid displacement and pressurizing device having a housing and a carrier member. A plunger extends through the carrier member, and plunger engaging structure is retained by the carrier member. The plunger engaging structure is selectively engageable with, and disengageable from, the plunger. The housing and carrier member are configured such that the carrier member is transversely installable in the housing. Preferably, both the carrier member and the plunger engaging structure form a sub-assembly, and the sub-assembly is transversely installable in the housing after having been assembled. By providing that the carrier member is transversely installable as a sub-assembly which includes the plunger engaging structure, the device is easy to assemble, and lends itself well to an automated assembly process. Integral handle and gripping features make control and operation of the devices easier, and allows for torsional operating loads to be resolved without reaching the device body.

A diagnostic hub located in a toilet receives a wireless signal from a mobile device of a user and determines that the user is proximate to the toilet based on the wireless signal. An identification of the user is determined based on the wireless signal. A geolocation of the diagnostic hub is determined. Sensor data generated by biometric sensors and environmental sensors is received. The diagnostic intakes a mixture of water and urine from the toilet into an intake chamber of the diagnostic hub through an inlet line or one or more openings in a housing of the diagnostic hub. A lab-on-a-chip of the diagnostic hub executes a biochemical assay on a fluid volume of the mixture using a reagent. Substance levels present in the urine are determined based on the biochemical assay. Results based on the substance levels are determined, indicating a diagnosis of one or more diseases or medical conditions.
