A method to guide in preparation of a bone relies on an instrument having a shaft with a working end and a stop member. The shaft is free to translate along an axis. Surgical planning data is registered to the bone to determine intra-operative coordinates of the desired axis and depth. The instrument holder is positioned by the bone so the stop member contacts the instrument holder to prevent translating beyond the desired depth. Alternatively, an arm is manipulated to align the instrument with the desired axis. The working end rests on the bone to define a linear separation to the desired depth. By proximally translating the instrument holder to contact the stop member and distally translating the instrument holder along the shaft, the stop member physically stops translating beyond the desired depth. A surgical system for performing the methods is provided; a reamer or impactor are also disclosed.

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 safety isolation bag is a pneumoperitoneum device for intra-abdominal, endoscopic procedures, power morcellation and vaginal morcellation for facilitating safe removal of body mass from within the abdominal cavity. It comprises of an expandable and collapsible enclosed internal space (5) having a neck portion (4) with mouth (3) having retractor means (2) and provided with markings, colour coded indicating how much the bag is to be pulled out for the removal of large, medium and small tissue mass, and also having one or more non-return valves (6) attached with long looped threads (8) on one of the surface in the wall of the safety isolation bag below the neck as a means for introducing the surgical instruments and accessories into the enclosed internal space at the right place and to close the puncture hole after the procedure. It is made of one or more layers of flexible biocompatible/medical grade plastic film.

A surgical light is provided, the surgical light comprising a light head including at least one illuminant configured to generate an illuminated area on a surgical site, and a sensor attached to the light head, wherein the sensor is configured to identify items used in surgery, and the sensor is attached to the light head such that a detection volume of the sensor is directed to the illuminated area.

An electrosurgical system is provided and includes a bipolar electrosurgical instrument and an electrosurgical generator. The bipolar electrosurgical instrument is arranged to seal and cut tissue captured between jaws of the bipolar electrosurgical instrument. The electrosurgical generator is arranged to supply RF energy through the bipolar electrosurgical instrument, monitor the supplied RF energy, and adjust or terminate the supplied RF energy to optimally seal the tissue.

A volume mapping instrument (20), deployable within a partially or a completely enclosed anatomical volume, employs one or more medical tools (40) with each medical tool (40) being transitional between a deployable structural configuration to orderly position each medical tool (40) within the anatomical volume and a mapping structural configuration to anchor the medical tool (40) against the boundary of the anatomical volume. The volume mapping instrument (20) further employs an optical shape sensor (30) to generate one or more encoded optical signals indicative of a shape of the boundary of the anatomical volume in response to each medical tool (40) being transitioned from the deployable structural configuration to the mapping structural configuration within the anatomical volume. Based on the encoded optical signal(s), a volume mapping module (51) is utilized to map a portion or an entirety of the boundary of the anatomical volume.

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.

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 tool for implementing a correction plan in an external fixation frame having a plurality of adjustment elements or screws, for example, generally includes a driver, a motor, a controller, and a processor. The driver is adapted to engage and rotate each of the screws. The motor is coupled the driver and adapted to rotate the driver. The controller is connected to the motor and configured to control operation of the motor. The controller may determine whether the tool is engaged with a strut and which strut is engaged, and may determine how much the strut has rotated, taking into account intentional or unintentional manual rotation of the tool. The tool may also include features to help ensure proper engagement between the drive and the strut. Variations may be provided in which similar functionality is provided with manual rotation of a motorless tool.
