Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Devices, systems, and techniques for controlling delivery of therapy for diabetes are described. In one example, a system includes a wearable device configured to generate user activity data associated with an arm of a user; and one or more processors configured to: identify at least one gesture indicative of utilization of an injection device for preparation of an insulin injection based on the user activity data; based on the at least one identified gesture, generate information indicative of at least one of an amount or type of insulin dosage in the insulin injection by the injection device; compare the generated information to a criteria of a proper insulin injection; and output information indicative of whether the criteria is satisfied based on the comparison.

Various embodiments of systems, devices and methods for improving the accuracy of an analyte sensor and for detecting sensor fault conditions are disclosed. According to some embodiments, these systems, devices, and methods can utilize a first data collected by a glucose sensor and a second data collected by a secondary sensing element. In some embodiments, the secondary sensing element can be one of a lactate sensing element, a ketone sensing element, or a heart rate monitor, among others.

Disclosed herein are medical devices, systems, and methods for collecting urine output from a patient, generally including a urine receiving device and a collection container coupled with the urine receiving device. Collection devices described herein can automatically determine collected urine volume, and also automatically determine protein content, salt content and pH of the collected urine. Collection devices can automatically display different colors according to collected volumes of urine. Some devices can determine the volume of urine within a patient's bladder. Systems can include a bladder volume device and logic to facilitate communication with external entities. Some systems may also include a urine collection device. Urine receiving devices can include external catheters.

The present specification discloses systems and methods of patient monitoring in which multiple sensors are used to detect physiological parameters and the data from those sensors are correlated to determine if an alarm should, or should not, be issued, thereby resulting in more precise alarms and fewer false alarms. Electrocardiogram readings can be combined with invasive blood pressure, non-invasive blood pressure, and/or pulse oximetry measurements to provide a more accurate picture of pulse activity and patient respiration. In addition, the monitoring system can also use an accelerometer or heart valve auscultation to further improve accuracy.

Systems and methods for visualizing ablated tissue are disclosed. In some embodiments, a system for imaging tissue comprising: a catheter having a distal end and a proximal end; an inflatable balloon disposed about the distal end of the catheter; and an optical housing extending from the distal end of the catheter into the balloon, the optical housing being configured to position inside the balloon a light source for illuminating a tissue outside the balloon and a camera for imaging the illuminated tissue.

Disclosed is a portable device for collecting and processing continuous monitoring data. The device has a data interface configured to receive a stream of continuous monitoring data from a body-worn sensor, the continuous monitoring data being indicative of an analyte in a bodily fluid. A control is connectable to the data interface. The control controls a first mode of operation during which configuration parameters are established in response to receiving a start signal indicating a sensor session start of the body-worn sensor. The control also controls a second mode of operation during which the continuous monitoring data is collected and processed and also controls the switching from the first mode to the second mode. The control blocks further starting of the first mode for a remaining sensor session time after the switching to the second mode of operation. Also disclosed are a related medical system, method and computer program product.

Disclosed are an implantable sensor driven by an alignment key, an implantable device comprising the implantable sensor, and a biometric data measurement system comprising the implantable device. The implantable device according to the present embodiment may comprise an implantable sensor forming a magnetic dipole moment in one direction from the inside to the outside of the body, and may be inserted into the body to measure biometric data by means of the implantable sensor.
