摘要： A neonatal pneumothorax decompression device is disclosed. The device comprises a needle stabilizer, a pressure indicator, and a fluid evacuation pump. The needle stabilizer is configured to facilitate insertion of the needle into a subject's pleural cavity and to hold a needle at an adjustable length. The pressure indicator is coupled to the proximal end of the needle stabilizer and is configured to visibly display pressure within the subject's pleural cavity. The fluid evacuation pump is configured to be actuated by a user to evacuate air or fluid from the subject's pleural cavity through the needle. The fluid evacuation pump is proximally coupled to the pressure indicator and the needle stabilizer.

摘要： An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a mounting ring which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the mounting ring and the clip.

摘要： Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.

摘要： An on-body insertion system is described. The on-body system includes a sensor in a first position being substantially parallel to an insertion surface. Activation of an actuator transitions the sensor to a second position. Wherein the transition imparts movement to the sensor that is substantially parallel to the insertion surface and the second position results in the sensing area being beneath the insertion surface.

摘要： A surgical cannula assembly includes an elongate cannula member having a plurality of longitudinal ribs extending along the longitudinal axis with adjacent longitudinal ribs defining a longitudinal channel therebetween, a fluid port mounted adjacent the proximal end of the cannula member and configured for coupling to a source of inflation fluids, a conduit positioned within at least one longitudinal channel of the cannula member and in fluid communication with the fluid port, and an expandable balloon mounted adjacent the distal end of the cannula member and in fluid communication with the conduit. The expandable balloon is configured to transition from an initial unexpanded condition to an at least partially expanded condition upon passage and entry of inflation fluids from the fluid port, through the conduit and within an internal volume of the expandable balloon.

摘要： An intraocular shunt can be placed into the eye in an ab externo approach. A clinician may determine an entry area below a corneal limbus of an eye and a target outflow region. Thereafter, the clinician can insert a hollow shaft into the eye at the entry area toward an anterior chamber of the eye, the shaft carrying an intraocular shunt therein. The clinician can position an inflow end of the shunt within the anterior chamber of the eye and, while maintaining the shunt inflow end in the anterior chamber, can remove the shaft from the eye to release the shunt. Finally, the clinician can repositioning an outflow end of the shunt within the target outflow region and verify placement of the outflow end of the shunt within the target outflow region.

摘要： Methods for surgical navigation use a trajectory frame/guide assembly for use with surgical navigation systems that includes a base having a patient access aperture formed therein. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis and interchangeably holds a single lumen or multi-lumen guide array and a device guide. A device guide can be rotated to align an access channel with a desired lumen path. No x-y actuators are required and a virtual guide array may also or alternatively be used to identify a desired open channel in the device guide for the preferred trajectory path.
