Abstract
A method for conducting intrabody surgery by means of a surgical device having a cutting arrangement actuated by a driveshaft and rotationally supported by the guide wire. A receiving cannel extends through the cutting arrangement and movably receives the guidewire. A plurality of sensors is provided within the cutting arrangement to emit signals capable of changing parameters depending on the composition of the occlusion, so as to allow the control unit to generate signals controlling operation of the cutting arrangement. The method includes the steps of detecting parameters within the intrabody area by the sensors to controlling operation of the cutting arrangement with the power and control unit.
Claims18
A device for intrabody surgery, comprising, a hollow guide wire and a cutting arrangement provided to drill away calcified occlusions in the blood vessel with rotatable driveshaft guided by the guide wire;
- wherein the guide wire is formed as a hollow tube having a plurality of openings along a distal end thereof to facilitate aspiration;
- the guide wire is used as a conduit for aspiration of occlusion debris produced by the cutting arrangement, and wherein the cutting arrangement is formed with a plurality of apertures enabling debris to be aspired through the apertures into the openings in the guide wire.
A method for conducting intrabody surgery by means of a surgical device, the surgical device comprising a cutting arrangement actuated by a driveshaft and rotationally supported by the guide wire, a receiving cannel extends longitudinally/along a longitudinal axis passing through the central part of the cutting arrangement body and is adapted to movably receive the guide wire there through, a plurality of sensors provided within the cutting arrangement to emit and receive various types type of signals (optical, electromagnetic, acoustical, capacitance measuring) capable of changing parameters depending on the composition of the occlusion, so as to allow the control unit generates signals controlling operation of the cutting arrangement,
- said method comprising the steps of:
- detecting one or more parameters within the intrabody area with said sensors and controlling operation of the cutting arrangement with the power and control unit, wherein rotational characteristics of the cutting arrangement are adjusted based on said parameters detected by said sensors.
A guidewire for a device for intravascular surgery, comprising a hollow tubal design in such a way that operator can remotely from the proximal end manipulate and/or bend the distal area of the guide wire to an optimum angle thus targeting it into a required direction within the patient body lumens.
