Abstract: Certain aspects relate to systems and techniques for medical instrument navigation and targeting. In one aspect, a system includes a medical instrument having an elongate body and at least one sensor, a display, a processor, and a memory storing a model of a mapped portion of a luminal network and a position of a target with respect to the model. The processor may be configured to: determine, based on data from the at least one sensor, a position and orientation of a distal end of the medical instrument with respect to the model, and cause, on at least a portion of the display, a rendering of the model, the position of the target, and the position and orientation of the distal end of the medical instrument. The rendering may be based on a viewpoint directed at the target and different from a viewpoint of the medical instrument.

Abstract: Provided is a MEMS condenser microphone, including a base plate, a spacer and a membrane. The membrane is supported above the base plate by the spacer. The base plate, the spacer, and the membrane enclose a vacuum cavity. An end of the membrane close to the vacuum cavity is connected, by means of a connecting rod, to an electrostatic clutch. The electrostatic clutch is connected to a capacitive sensing structure. The microphone has the advantage of allowing microphone performance over a wide range of atmospheric pressures which is likely expected by customers. This is achieved electrostatically in a purely passive way which has an advantage over other designs which require complex electronics and active control. Physically decoupling the membrane and sense structure simplifies the design of the sense structure as only small AC perturbations of the rotor need to be considered with no DC changes in rotor position.

Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.

The first plunger is configured to move the spacer and the container relative to the housing via the first spring to establish fluid communication between the container and the patient needle, and the second plunger is configured to move the spacer and the stopper relative to the container via the second spring.

Abstract: Golf clubs and golf club heads having a weight member that is configurable in multiple positions to alter the performance characteristics of the golf club head are presented. In some examples, the weight member may be arranged in a sole of the golf club head and may include ends having different weighting characteristics. For instance, one end may be heavier or denser than another end of the weight member. The difference in weight characteristics may be due to different materials used to form the different ends, different construction of the ends, and the like. The position of the weight member may be adjusted to alter the performance characteristics of the golf club head. For instance, the weight member may be removed and rotated to position a heavier end where a lighter end was previously positioned.

User data from the user account can then be used to generate one or more augmented reality display elements that can be anchored to the image feature in the one or more images.

The electrostatic clutch includes: multiple arrays of HIN electrodes, a respective pass-through channel being formed between any two arrays of the multiple arrays of HIN electrodes; and multiple arrays of biased electrodes, each array of the multiple arrays of biased electrodes moving back and forth in the respective pass-through channel such that electrostatic force is generated between the multiple arrays of biased electrodes and the multiple arrays of HIN electrodes.

This is achieved electrostatically in a purely passive way having advantages over other designs which require complex electronics and active control. Physically decoupling the membrane and sense structure simplifies design of the sense structure as only small AC perturbations of the rotor is considered with no DC changes in rotor position.

The MEMS device includes: a substrate having a cavity passing through the substrate; a diaphragm connected to the substrate and covers the cavity. The diaphragm includes oppositely arranged first and second membranes. The first membrane is on one side of the second membrane facing away from the cavity and includes a first protrusion extending away from the second membrane, the first protrusion has a first groove opening towards the second membrane. The second membrane includes a second protrusion extending away from the first membrane and opposite to the first protrusion, the second protrusion has a second groove opening towards the first membrane. By providing first and second protrusions on first and second diaphragms to form a corrugated diaphragm, the internal stress and stiffness of the diaphragm decreases, which effectively increases the mechanical sensitivity of the MEMS device.
