Abstract
A device for accessing and for isolating a desired site within a patient's body, and for obtaining a body of tissue from a patient at the site that includes an electrosurgical cutting electrode near the distal tip of a shaft, an anchoring mechanism and an electrosurgical side-cutting device. Methods are provided for accessing a target site within a patient's body, anchoring a body of tissue at the site, and isolating the body of tissue, at the site. The method may be performed for a surgical biopsy or lumpectomy at the target site within a patient's body.
Claims36
A device for accessing target tissue within a patient and isolating a body of target tissue from its supporting bed, comprising:
- an elongated shaft having a distal end, a proximal end and a longitudinal axis;
- an electrosurgical electrode secured to the distal end of the shaft;
- a first electrical conductor extending within the shaft having a distal end electrically connected to the electrosurgical electrode and a proximal end configured to be electrically connected to an electrical power source;
- a tissue anchoring mechanism located proximal to the distal end;
- and
- a side-cutting mechanism having a cutting element configured to be rotated about the longitudinal axis of the shaft and thereby isolate a body of target tissue.
An electrosurgical device for obtaining a body of target tissue within a patient, comprising:
- an elongated shaft having a distal end, a proximal end and a longitudinal axis;
- an electrosurgical electrode secured to the distal end of the shaft;
- a first electrical conductor extending within the shaft having a distal end electrically connected to the electrosurgical electrode and a proximal end configured to be electrically connected to an electrical power source;
- an anchoring mechanism located proximal to the distal end configured to extend outwardly into the target tissue;
- and
- a side-cutting mechanism having a cutting element configured to be rotated about the longitudinal axis of the shaft and thereby isolate a body of target tissue.
A device for performing a lumpectomy on a patient's breast, comprising:
- an elongated shaft having a distal end, a proximal end and a longitudinal axis;
- an electrosurgical electrode secured to the distal end of the shaft;
- a first electrical conductor extending within the shaft having a distal end electrically connected to the electrosurgical electrode and a proximal end configured to be electrically connected to an electrical power source;
- an anchoring mechanism located proximal to the distal end;
- and
- a side-cutting mechanism having a cutting element configured to be rotated about the longitudinal axis of the shaft and thereby isolate a body of target tissue.
