An optical fiber optically communicated with the photonic device. The photonic device bi-directionally communicates an optical signal with the optical fiber. An optical interface device provides optical power to the optical fiber and thence to the photonic device and receives optical signals through the optical fiber from the photonic device. The optical interface device bi-directionally communicates electrical data, control, and power signal to the computer.

System for guiding an instrument within a vascular network of a patient are disclosed. In some embodiments, the system receives a medical image from a medical imaging device and identifies a distal tip and a direction the instrument in the image. The system may then determine a waypoint for the distal tip of the instrument based at least in part on the position and direction of the distal tip of the instrument. The system may then generate a trajectory command for moving the instrument through the vascular network from the current position to the waypoint. The system may operate in a closed loop. The system may provide the trajectory command to a robotic medical system configured to move the instrument according to the command.

An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween; a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle; and an actuator extending from the proximal end of the proximal section to actuate a drive mechanism having a needle driver for engaging and rotating the suturing needle.

A backend mechanism of a control system for an elongated medical instrument includes a tool holder to retain and move a tool relative to the elongated medical instrument.

This disclosure provides methods, devices, and systems for localizing medical instruments. The present implementations more specifically relate to techniques for localizing a distal tip of an elongate medical instrument based at least in part on first sensor data received from one or more first sensors disposed in a proximal hub of the instrument. For example, the first sensor data may indicate a position and/or orientation of the proximal hub, which can be used to determine a position and/or orientation of the distal tip based on a known length of the instrument. In some implementations, the controller may further determine a shape of the instrument based on second sensor data received from one or more second sensors disposed on a shaft and/or distal tip of the instrument. In such implementations, the position and/or orientation of the distal portion may be further determined based on the shape of the instrument.

The deformable portion is deformable in elongation/contraction along a main axis connecting the head portion and the rear portion. The head portion includes at its surface at least one propulsion cilium, one end of the at least one propulsion cilium being attached to the head portion and the other end of the at least one propulsion cilium being a free end configured to move freely in the viscous material. The propulsion structure further includes a motor configured to actuate sequentially elongation/contraction cycles of the deformable portion.

A system for delivery of cardiac implants includes a catheter having a handle assembly including a cable control assembly. The handle assembly further includes a tubular body assembly extending distally from the handle assembly and deflectable by operation of the cable control assembly. The system also includes a robot having a linear displacement platform and a carriage coupled to the linear displacement platform.
