Medical device systems and methods for making and using medical device systems are disclosed. An example medical device system may include a guidewire. A pressure sensor assembly may be disposed within the guidewire. The pressure sensor assembly may include a pressure sensor and a first optical fiber coupled to the pressure sensor. The first optical fiber may have a first outer diameter. A cable may be coupled to the guidewire. The cable may include a second optical fiber. The second optical fiber may have a second outer diameter greater than the first outer diameter.

Robotic surgical tools, systems, and methods for preparing for and performing robotic surgery include a memory mounted on the tool. The memory can perform a number of functions when the tool is loaded on the tool manipulator: first, the memory can provide a signal verifying that the tool is compatible with that particular robotic system. Secondly, the tool memory may identify the tool-type to the robotic system so that the robotic system can reconfigure its programming. Thirdly, the memory of the tool may indicate tool-specific information, including measured calibration offsets indicating misalignment of the tool drive system, tool life data, or the like. This information maybe stored in a read only memory (ROM), or in a nonvolatile memory which can be written to only a single time. The invention further provides improved engagement structures for coupling robotic surgical tools with manipulator structures.

Surgical robotic tools, data architecture, and use

Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.

The present invention generally relates to medical devices, and more particularly to an improved intravascular device. In one embodiment, an intravascular device includes a catheter having proximal and distal portions, and a phased array of imaging elements, having edge elements each having angles of emission, located in the distal portion of the catheter, wherein the phased array is concaved having a radius of curvature such that when the phased array is steered in a maximal azimuthal direction, the angles of emission of the edge elements are substantially similar.

This invention relates to a stereo imaging system for use in telerobotic systems. A method of imaging a target site in a stereo imaging system is provided. The method typically includes capturing a right and a left optical image of the target site and transforming the right and the left optical images preferably into digital information. The method further includes converting the digital information into opposed images of the target site displayed on a stereo display of the stereo imaging system, one of the opposed images being associated with the right optical image and the other of the opposed images being associated with the left optical image. The method further includes regulating the digital information to cause the positions of the target site displayed on the opposed images to change relative to each other. The invention further provides for a method of aligning the opposed images, to a method of adjusting the stereo working distance of an image capture device, such as an endoscope and to a stereo imaging system.

Robotic surgical tools, systems, and methods relating to robotic surgery include a memory mounted on the tool. The memory can perform a number of functions when the tool is loaded on the tool manipulator: (1) providing a signal verifying that the tool is compatible with that particular robotic system; (2) identifying the tool-type to the robotic system so that the robotic system can reconfigure the programming; or (3) indicating tool-specific information, including measured calibration offsets indicating misalignment of the tool drive system, tool life data, or the like. This information may be stored in a read only memory (ROM), or in a nonvolatile memory which can be written to only a single time. Also provided are improved engagement structures for coupling robotic surgical tools with manipulator structures.

Improved robotic surgical systems, devices, and methods often include a first assembly with a surgical end effector supported and manipulated relative to a first base by a first robotic linkage, while a second surgical end effector manipulated and supported relative to a second, independent base by a second robotic linkage. One or more of these robotic assemblies may be moved relative to the other. To coordinate the end effector movements with those of input devices being manipulated by a surgeon relative to a display of a surgical worksite, the processor deriving the commands for movement of the robotic linkages may make use of a signal indicating a relative orientation of the bases of the robotic arm assemblies. Surprisingly, the robotic arm assemblies may not transmit signals to the processor indicating a relative translational position of the bases.
