A surgical access device is adapted to facilitate access through an incision in a body wall having an inner surface and an outer surface, and into a body cavity of a patient. The device includes first and second retention members adapted to be disposed in proximity to the outer surface and the inner surface of the body wall, respectively. A membrane extending between the two retention members forms a throat which is adapted to extend through the incision and form a first funnel extending from the first retention member into the throat, and a second funnel extending from the second retention member into the throat. The throat of the membrane has characteristics for forming an instrument seal in the presence of an instrument and a zero seal in the absence of an instrument. The first retention member may include a ring with either a fixed or variable diameter. The ring can be formed in first and second sections, each having two ends. Couplings can be disposed between the ends to accommodate variations in the size of the first retention member. The first retention member can also be formed as an inflatable toroid, a self-expanding foam, or a circumferential spring. A plurality of inflatable chambers can also provide the surgical access device with a working channel adapted for disposition across the body wall. A first retention member with a plurality of retention stations functions with a plurality of tethers connected to the membrane to change the shape of the membrane and the working channel. A stabilizing platform can be used to support the access device generally independent of any movement of the body wall.

Method, apparatus, and kit for thermal suture cutting
InactiveUS7699856B2Reduce tensionMinimize disruptionSuture equipmentsDiagnosticsForcepsRemoval techniques
A novel suture removal instrument, kit and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and / or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

Autofocus and/or autoscaling in telesurgery
ActiveUS8079950B2Enhance perceived correlationComputer controlSimulator controlRemote surgeryComputer graphics (images)
Robotic, telerobotic, and / or telesurgical devices, systems, and methods take advantage of robotic structures and data to calculate changes in the focus of an image capture device in response to movement of the image capture device, a robotic end effector, or the like. As the size of an image of an object shown in the display device varies with changes in a separation distance between that object and the image capture device used to capture the image, a scale factor between a movement command input may be changed in response to moving an input device or a corresponding master / slave robotic movement command of the system. This may enhance the perceived correlation between the input commands and the robotic movements as they appear in the image presented to the system operator.

The invention provides surgical or diagnostic tools and associated methods that offer user control for operating remotely within regions of the body. These tools include a proximally-located actuator for the operation of a distal end effector, as well as proximally-located actuators for articulational and rotational movements of the end effector. Control mechanisms and methods refine operator control of end effector actuation and of these articulational and rotational movements. An articulation lock allows the fixing and releasing of both neutral and articulated configurations of the tool and of consequent placement of the end effector. The tool may also include other features. A multi-state ratchet for end effector actuation provides enablement-disablement options with tactile feedback. A force limiter mechanism protects the end effector and manipulated objects from the harm of potentially excessive force applied by the operator. A rotation lock provides for enablement and disablement of rotatability of the end effector.

Implantable joint prosthesis
InactiveUS20020035400A1Improve wear resistanceImprove tribological propertiesDiagnosticsJoint implantsRange of motionIntervertebral disc
The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable. Desirably, the outer surfaces of the shells are adapted to allow for bony ingrowth, which further stabilizes the shells in place. The inner surfaces of the shells are relatively smooth, and adapted to slide easily across a portion of the outer surface of a central body disposed between the shells. The central body has a shape that cooperates with the shape of the inner surface of the shell so as to provide a range of motion similar to that provided by a healthy joint. A flexible sheath extends between edges of the opposing shells. The inner surface of this sheath, together with the inner surfaces of the rigid shells, defines a cavity encasing the central body. At least a portion of this cavity is filled with a fluid lubricant, further decreasing the frictional force between inner surfaces of the shell and the surface of the central body.
