Abstract
A medical device comprising a flexible, elongated member sized and shaped to fit within a vessel and defining a first lumen. A distal end of the flexible, elongated member including a port for connection to a vacuum source. A wire is slideably positionable within the first lumen and is movable between a first position and a second position. A cutting instrument is attached to a distal end of the wire and is retracted within the distal end of the lumen when the wire is at the first position and extending outside the distal end of the lumen when the wire is at the second position.
Claims8
A medical device for removably holding a tissue while a procedure is performed, said medical device comprising:
- a flexible elongate member defining a first lumen extending therethrough, said flexible elongate member and said first lumen having a proximal end and a distal end, said flexible elongate member being sized and shaped to fit within a vessel, and the lumen of said elongate member in communication with a port for connection to a vacuum source;
- a wire slideably positionable within said first lumen, said wire having a proximal end and a distal end, and said wire being movable between a first position and a second position;
- and
- a cutting device attached to the distal end of said wire, said cutting device being retracted within the distal end of the lumen when the wire is at said first position, said cutting device being extended outside the distal end of said lumen when the wire is at said second position.
A method for performing a procedure on a tissue, said method comprising the steps of:
- a. providing a medical device comprising:
- (i) a flexible elongate member with a first lumen extending therethrough, said elongate member and said first lumen having a proximal end and a distal end, said elongate member being sized and shaped to fit within a vessel, and the lumen of said elongate member in communication with a port for connection to a source,
- (ii) a wire slideably positionable within said first lumen, said wire having a proximal end and a distal end, and said wire being movable between a first position and a second position,
- (iii) a cutting device attached to the distal end of said wire, said cutting device being retracted within the distal end of the lumen when the wire is at said first position and being extended outside the distal end of said lumen when the wire is at said second position
- b. inserting the distal end of the flexible elongate member into the body of the patient and moving it to the tissue interest;
- c. activating said source to reversibly adhere the distal end of said lumen to the tissue of interest;
- d. advancing said cutting device into the target tissue creating an opening in said tissue;
- e. advancing a guide member through the opening in said tissue;
- and
- f. removing the distal end of the flexible elongate member from the body of the patient.
