The present teaching relates to surgical procedure assistance. In one example, a first volume of air inside a lung is obtained based on a first image of the lung captured prior to a surgical procedure. The lung has a first shape on the first image. A second volume of air deflated from the lung is determined based on a second image of the lung captured during the surgical procedure. A second shape of the lung is estimated based on the first shape of the lung and the first air volume inside the lung and second volume of air deflated from the lung. A surgical plan is updated based on the estimated second shape of the lung.

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.

A method for performing percutaneous spinal interbody fusion on a spine of a patient can include inserting without direct visualization a neuro-monitoring dilating probe into the patient, performing neuro-monitoring via the neuro-monitoring dilating probe, advancing the neuro-monitoring dilating probe into a disc space, passing a second dilator over the neuro-monitoring dilating probe, and advancing the second dilator into the disc space. A kit for performing percutaneous spinal interbody fusion can include a neuro-monitoring dilating probe, a second dilator, a tissue removal tool, an access portal comprising an adjustable depth stop, and a discectomy verification device.

Catheter system, devices and methods for diagnosing and treating lateral stenosis causing back pain and or leg pain. The devices comprise a tubular part for insertion into a working cannula to self-position itself safely within the foramen, and minimize the risk of displacement medially or laterally, to prevent nerve or dura injury. An expandable membrane is configured to maintain the catheter device within the foramen. Expansion of this membrane would decompress the nerve within the foramen by opening the foraminal canal as the membrane expands.

An ultrasonic aspirator includes a body, an aspirator wand extending from the body, a shield to cover the aspirator wand, a removable headpiece removably attached to the aspirator wand, and a guard extending past an end of the headpiece in a direction distal to the body, the aspirator also includes a generator or a detector to generate or detect electrical pulses, light sources, endoscopy, modified body angles, image navigation integration for improved visualization and optimization of the surgical field.

Disclosed are various embodiments for improved surgical devices and methods of using the same in connection with bariatric and gastroesophageal surgery. The present disclosure includes a lighted bougie device that can include an elongate member and a light source. The light source can be configured to emit near-infrared light. The light source can also be positioned about the bougie such that light emitted from the light source illuminates along a portion of the bougie.

A method for performing a diagnostic or therapeutic procedure on a partial occlusion within a blood vessel, includes positioning a guide having a sensor configured and adapted to measure at least one of pressure, volume or flow within a blood vessel, advancing the guide through an at least partial occlusion within the blood vessel such that the sensor is downstream of the occlusion, measuring at least one of pressure, volume or flow downstream of the occlusion using the sensor and analyzing data obtained from the sensor to assist in determining the viability of tissue of the blood vessel downstream of the occlusion.

A surgical apparatus includes an elongate outer sheath dimensioned for positioning within a body lumen of a patient, a reference member and a removal device. The reference member is adapted for longitudinal movement relative to the elongate outer sheath between a first position at least partially disposed within a longitudinal lumen of the outer sheath and a second position at least partially exposed from the longitudinal lumen. The reference member is adapted to expand when in the second position to generally conform to an internal dimension of the body lumen. The reference member includes a radiopaque material for visualizing the reference member to assist in determining physical characteristics of the body lumen when in the second position. The removal device is adapted for longitudinal movement relative to the reference member, and is configured for disrupting at least a portion of the occlusion within the body lumen.
