A device with a flexible member configured to take on a curvilinear profile can be used to perform arthroscopic procedures. The device can be used to perform such procedures through two access ports, providing visualization and access to the entire site of the procedure, e.g. hip joint, without switching cannulated access portals or providing additional access portals.

A medical guidewire having distal tip coil that includes a twisted ribbon wire construction. The distal tip coil is mounted to the distal end of the distal core section of the guidewire. The coil is made from a flat ribbon wire with a polygonal, preferably rectangular, cross-section that is twisted along the length of the wire. The twisted, flat ribbon wire creates a tip coil that has a roughened, undulating surface at the outer circumference that, whether coated or bare, is perceptible to the physician or cardiologist when pushing or torquing the guidewire in an interventional procedure.

Methods, articles of manufacture, and devices related to generating six degree of freedom (DOF) haptic feedback are provided. A computing device can receive first depth data about an environment. The computing device can generate a first plurality of points from the first depth data. The computing device can determine a virtual tool, where the virtual tool is specified in terms of a translation component for the virtual tool and a rotation component for the virtual tool. The computing device can determine a first force vector between the virtual tool and the first plurality of points. The computing device can send a first indication of haptic feedback based on the first force vector.

A method and apparatus for transecting soft tissue, such as a ligament, and more particularly, the transverse carpal ligament. A retrieval tool and a threadlike cutting element enable the method to performed in a minimally invasive manner. The cutting element is routed into position about the target ligament such that the cutting element both enters and exits the body from the same side of the ligament. The smooth exterior surface of the cutting element serves to provide for a kerf-less cut.

Apparatus and methods for defining and utilizing virtual fixtures for haptic navigation within real-world environments, including underwater environments, are provided. A computing device can determine a real-world object within a real-world environment. The computing device can receive an indication of the real-world object. The computing device can determine a virtual fixture that corresponds to the real-world object based on the indication, where aspects of the virtual fixture are configured to align with aspects of the real-world object. The computing device can provide a virtual environment for manipulating the robotic tool to operate on the real-world object utilizing the virtual fixture. The virtual fixture is configured to provide haptic feedback based on a position of a virtual robotic tool in the virtual environment that corresponds to the robotic tool in the real-world environment.

Frequency multiplexed command signaling that permits a single pilot command interface (e.g. control stick) to serve as a multiple response mode interface for piloting a craft conforms with natural interface operation of most pilots. Highly augmented modes receive lower frequency components of the command signaling, and less augmented modes receive higher frequency components. This avoids the requirement for pilots to switch response modes. An embodying control system can be produced by running feedback control loops encoding the respective response modes in parallel, and multiplexing the command signaling to each response mode, filtering each copy of the command signaling respectively according the respective feedback control loop, and then combining the output of each feedback control loop to compute actuation demand.

A method for computer-assisted planning of a transplant surgery is provided. The method includes obtaining a computer-readable representation of a donor and recipient skeletal fragment; determining surgical cutting planes on the computer-readable representation of the donor skeletal fragment from which a portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment will be harvested; determining virtual cutting guides; performing a virtual osteotomy to separate the portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment from a remainder portion of the donor skeletal fragment based on a position of the virtual cutting guides that are attached to the computer-readable representation of the donor skeletal fragment; positioning the donor skeletal fragment within a transplant region of the recipient skeletal fragment; and creating a hybrid computer-readable representation comprising the recipient skeletal fragment and the portion of the donor skeletal.

A surgical device is provided, the device having a tubular outer body member with a handle at its proximal end and a flexible distal end segment extending from its distal end. The surgical device also has an operable end extending from the distal end of the flexible distal end segment. The device is configured for selectively causing the flexible end segment to bend to adopt a desired curvature and for selectively rotating the operable end relative to the flexible distal end segment about an axis of the flexible distal end segment.
