Abstract
The present invention discloses medical systems and methods adapted for the delivery of various medical components such as microwave antennas within or on a body for performing one or more medical procedures. Several embodiments herein disclose medical systems comprising a combination of one or more medical components and one or more elongate steerable or non-steerable arms that are adapted to mechanically manipulate the one or more medical components. Several embodiments of microwave antennas are disclosed that comprise an additional diagnostic or therapeutic modality located on or in the vicinity of the microwave antennas.
Claims38
A microwave emitting system for delivering microwave energy comprising:
- a transmission line coupleable to a microwave energy source;
- an elongate microwave antenna having a proximal end, a distal end and an antenna axis, wherein the proximal end of the antenna is electrically coupled to the distal end of the transmission line and where the elongate microwave antenna generates a microwave field upon application of the microwave energy to the transmission line;
- an electrode positioned along the microwave antenna and between the proximal end and the distal end of the antenna, wherein the electrode is exposed to the microwave field emitted by the antenna and is electrically isolated from the antenna, where the electrode is coupleable to a second power supply;
- and
- a conductive wire coupled to the electrode wherein the wire is electrically isolated from the antenna and wherein a first portion of the wire exposed to the microwave field emitted by the antenna is disposed relative to the antenna axis such that every section of the first portion of the wire is non-parallel to the axis of the antenna such that arrangement of the conductive wire relative to the antenna reduces distortion of the microwave field due to the electrode.
A method of delivering microwave energy to tissue comprising the steps of:
- positioning an elongate microwave antenna adjacent to a first region of tissue wherein the antenna comprises a proximal end, a distal end and an antenna axis and an electrode is located over the antenna and between the antenna and the first region of tissue where a wire is connected to the electrode and is electrically isolated from the antenna and wherein a first portion of the wire is exposed to the microwave field emitted by the antenna such that every section of the first portion of the wire is oriented non-parallel to the axis of the antenna;
- delivering microwave energy to the first location of tissue through the elongate microwave antenna to generate a microwave field where the position of the conductive wire reduces a distortion of the microwave field otherwise resulting from the electrode and to create a first lesion;
- and
- applying energy through the electrode to diagnose or treat the tissue while maintaining a position of the antenna.
A microwave emitting system for delivering microwave energy comprising:
- a transmission line coupleable to a microwave energy source;
- and
- an elongate microwave antenna having a proximal end, a distal end and an antenna axis, wherein the proximal end of the antenna is electrically coupled to the distal end of the transmission line,
- a diagnostic or therapeutic modality located over the microwave antenna and between the proximal end and the distal end of the antenna, wherein the diagnostic or therapeutic modality is exposed to the microwave field emitted by the antenna and is electrically isolated from the antenna
- a conductive wire connected to the diagnostic or therapeutic modality wherein the wire is electrically isolated from the antenna and wherein a first portion of the wire exposed to the microwave field emitted by the antenna is disposed relative to the antenna axis such that every section of the first portion of the wire is held non-parallel to the axis of the antenna.
