International Classification:

A61B 17/00

US Classification:

606 1, 606130, 606205

Abstract:

A robotically controlled surgical instrument includes a first jaw and a second jaw used to grasp an item, and a drive mechanism that increases the force applied to the item grasped.

International Classification:

A61B 1/005

US Classification:

600102, 600117, 600118, 128898

Abstract:

A method of performing a medical procedure on a patient comprises introducing a medical instrument into a patient (e. g. , percutaneously), conveying control signals from a remote controller to a drive unit, and operating the drive unit in accordance with the control signals to actuate the tool located on the medical instrument to secure a stent to an anatomical vessel (e. g. , a blood vessel, such as an abdominal aorta). The tool may be a sewing tool that is controlled to stitch the stent to the anatomical vessel. In one method, the control signals are conveyed from the remote controller to the drive unit in response to user commands. The user commands may be movements made at a user interface that correspond to movements of the medical instrument.

International Classification:

A61B017/00

US Classification:

606/001000

Abstract:

A robotic medical apparatus for performing a medical procedure or application on an anatomy, said apparatus comprising: a first medical instrument member having a working end adapted to be disposed at an internal target area at which the medical procedure or application is to be performed; and a second medical instrument member having a working end adapted to be disposed at an internal target area at which the medical procedure or application is to be performed. The first medical instrument member is disposed so as to extend into the anatomy at a first ingress location and passing intraluminally; and the second medical instrument member is disposed so as to extend into the anatomy at a second ingress location different than said first ingress location and passing extraluminally. A controller is provided for receiving remotely generated control commands for respectively controlling the motion of said first and second medical instrument members so that said first and second medical instrument members are separately and controllably operable to perform the medical procedure or application.

International Classification:

A61B 17/94

US Classification:

600118000

Abstract:

A method of performing a medical procedure on a patient comprises conveying control signals from a remote controller to a drive unit, intraluminally introducing a first medical instrument within the patient, extraluminally introducing a second medical instrument within the patient, and operating the drive unit in accordance with the control signals to actuate a first tool on the first medical instrument and a second tool on the second medical instrument, in unison, to perform the medical procedure at a target region within an anatomical vessel. In one method, the control signals are conveyed from the remote controller to the drive unit in response to user commands, which may be movements made at a user interface that correspond to movements of the medical instrument.

International Classification:

A61B 17/03

US Classification:

606147000

Abstract:

A medical system and method of performing a medical procedure on a patient are provided. An electrical controller directs an electromechanical driver to bend an elongated member back upon itself to place a active work element in a working relationship with an intermediate work element, and to respectively control the active work element and intermediate work element, in unison, to perform a medical procedure. The electrical controller may be remote from the electromechanical driver, and may be coupled to the electromechanical driver via external cabling. The electrical controller may have a user interface for receiving commands from a user. In this case, the movements made at the user interface correspond to movements of the medical instrument.

International Classification:

A61B 17/32

US Classification:

606170000

Abstract:

A method of performing a medical procedure (e.g., a cardiac bypass procedure) on a patient comprises introducing at least one medical instrument into a patient (e.g., percutaneously), conveying control signals from a remote controller to a drive unit, and operating the drive unit in accordance with the control signals to actuate at least one tool respectively located on the medical instrument(s) to transversely secure a first anatomical vessel (e.g., a blood vessel) to a sidewall of a second anatomical vessel (e.g., another blood vessel). In one method, the control signals are conveyed from the remote controller to the drive unit in response to user commands. The user commands may be movements made at a user interface that correspond to movements of the medical instrument(s).
