Abstract

A device for locating an operational unit within a patient'"'"'s body within the framework of a minimally-invasive surgery intervention includes a shaft having a distal end carrying an operational unit. The device includes an illuminator located at the distal end of the shaft. The illuminator is selectively adjustable to provide a selectively variable lighting field in correspondence with the operational unit. The device may be, for example, a delivery system for a heart valve or a balloon device for post-dilation of such a heart valve once implanted.

Claims

1. A device for implanting a prosthetic heart valve at an implantation site, the device including:

a shaft having a distal end adapted to couple to the prosthetic heart valve and maintain the valve in a collapsed configuration;

an illuminator selectively adjustable to provide a variable lighting field, the illuminator coupled at or near the distal end of the shaft;

an optical fiber extending through at least a portion of the shaft, the optical fiber having a proximal end extending from a proximal end of the shaft and a distal end coupled to the illuminator, the optical fiber is adapted to transmit the lighting field from the illuminator to the distal end of the shaft; and

an actuator coupled to the illuminator and adapted to effect a change to the variable lighting field.

2. A device for locating an operational unit within a patient'"'"'s body, the device including a shaft having a distal end carrying the operational unit, wherein the device includes an illuminator located at the distal end of the shaft, the illuminator selectively adjustable to provide a selectively variable lighting field at the operational unit.

3. The device of claim 2, wherein the operational unit is selected out of a heart valve delivery unit, a post-dilation balloon member for a heart valve, a unit for the ablation of natural valve leaflets, and a sizer unit for sizing a valve implantation site.

4. The device of claim 2, wherein the illuminator includes at least one of a reflector and a diffuser.

5. The device of claim 2, including adjustment means at the proximal end of the device whereby at least one of the geometry and the position of the illuminator to provide a selectively variable lighting field at the operational unit is made variable.

6. The device of claim 2, including an elongated optical element to convey light radiation along the shaft, wherein the illuminator includes the distal end of the elongated optical element.

7. The device of claim 2, including an elongated optical element to convey light radiation to the illuminator along the shaft, the element adapted to be moved with respect to the shaft to selectively displace the illuminator to provide a selectively variable lighting field at the operational unit.

8. The device of claim 7, including a lock means actuatable to prevent and permit, respectively, displacement of the elongated optical element with respect to the shaft.

9. The device of claim 2, wherein the illuminator includes an autonomous light source located at the distal end of the shaft.

10. The device of claim 9, wherein the autonomous light source is a LED source.

11. The device of claim 9, including an electrical line to convey along the shaft electrical energizing power for the autonomous light source.

12. The device of claim 11, including the electrical line adapted to be moved with respect to the shaft to selectively displace the illuminator to provide a selectively variable lighting field at the operational unit.

13. The device of claim 2, wherein the shaft includes a distal transparent portion for light radiation from the illuminator to propagate therethrough.
