Abstract
An apparatus and method for performing a medical procedure comprising an elongated shaft having an aperture extending longitudinally therethrough. An actuator tube is positioned within the shaft and a guide wire extends through the tube. A head is attached at one end of the shaft by the guide wire. A specimen is cut by a blade disposed on either the shaft or the head. The device is used to enlarge a lumen that has been occluded with diseased or stenotic tissue.
Claims30
An apparatus for performing a medical procedure, comprising:
- an elongated shaft comprising an aperture extending longitudinally therethrough, said shaft having a proximal and an opposite distal end;
- an actuator tube positioned within the aperture, said actuator being hollow and having a proximal end and an opposite distal end;
- a wire guide disposed throughout the actuator tube extending from the proximal and opposite distal ends of the shaft.
- cutting means connected to the distal end of the actuator tube for cutting and collecting tissue specimens;
- and
- a first cap positionable over a portion of the apparatus when said portion is removed from the apparatus, said first cap sealing said portion for storage of tissue specimens collected by the cutting means.
A method for enlarging a lumen that is occluded with diseased or stenotic tissue, comprising:
- inserting a device having an elongated hollow member having a cutting means into the lumen.
- cutting, coring and scraping the tissue with the cutting deployed from the elongated hollow member;
- capturing the tissue within the elongated hollow member in order of collection;
- removing said cutting means from the elongated member;
- and
- sealing the elongated member with at least one perforated cap, creating a processing cassette for the tissue.
A method for enlarging a lumen that is occluded with diseased or stenotic tissue, comprising:
- inserting a device having an elongated hollow member having a cutting means into the lumen.
- cutting, coring and scraping the tissue with an apparatus having a hollow head with a cutting blade on said hollow head;
- placing the tissue within said hollow head in order of collection;
- removing the hollow head from the apparatus;
- and
- sealing the hollow head with a perforated cap creating a processing cassette for the specimens.
