Abstract
Aspects of the present invention are generally directed to a biopsy device configured to engage target tissue within a patient and to remove a sample of the target tissue from the patient. The biopsy device comprises an elongate catheter configured to be inserted into a patient. A coring component is disposed at the distal end of the catheter to sample the target tissue.
Claims20
A device for sampling target tissue within a patient, comprising:
- a coring component having:
- a longitudinal lumen terminating in a distal opening;
- and
- a distal region formed of one or more distally extending blades each having a distal end positioned around said distal opening,
- wherein said one or more blades are configured to penetrate the target tissue such that a tissue sample having a cross-section defined by said distal ends of said one or more blades is received within said lumen of said coring component via said distal opening, and
- wherein said blades are configured to substantially sever said tissue sample from the target tissue.
3 more elements
The device of claim 4, wherein a distal region of at least one of said blades opposing said lumen of said coring component comprises a beveled surface.
