An electrosurgical energy channel splitter apparatus includes a channel input a plurality of channel outputs, and a controller. The channel input is configured to receive electrosurgical energy from an electrosurgical energy source. Each channel output is configured to couple to a respective electrosurgical device. The controller is coupled to the channel input and the plurality of channel outputs. The controller is configured to selectively direct the electrosurgical energy from the channel input to one of the plurality of channel outputs.

Electrosurgical energy channel splitters and systems for delivering electrosurgical energy

An antenna guide assembly including a guide body having a proximal end defining at least one proximal entry, a distal end defining at least one distal port, and at least one guide passage extending between the proximal and distal ends. The at least one guide passage is configured to receive at least a portion of an antenna therethrough via the at least one proximal entry such that a distal portion of the antenna extends through and distally from the at least one distal port for insertion into tissue. A locking assembly disposed at the distal end of the guide body is configured to receive the distal portion of the antenna therethrough. The locking assembly is configured to selectively engage the distal portion of the antenna to prevent translation of the antenna within the at least one guide passage.

Microwave antenna guide assembly

A marking device for identifying a subcutaneous biopsy cavity having a first nonabsorbable marker element detectable by a first imaging modality and a second nonabsorbable marker element detectable by a second imaging modality but not detectable by the first imaging modality.

Subcutaneous biopsy cavity marker device

An electrosurgical energy generator apparatus includes a microwave generator configured to supply microwave energy and an RF generator configured to supply RF energy. A power supply is coupled to the microwave generator and the RF generator and is configured to supply power to each of the microwave and RF generators. A first output is coupled to the microwave generator and is configured to deliver microwave energy. A second output is coupled to the RF generator and is configured to deliver RF energy.

Microwave antenna having a curved configuration

A microwave antenna having a curved configuration is described herein. The antenna portion is formed into various shapes whereby the antenna substantially encloses, by a partial or complete loop or enclosure, at least a majority of the tissue to be irradiated. When microwave energy is delivered through the antenna, the curved configuration forms an ablation field or region defined by the curved antenna and any tissue enclosed within the ablation region becomes irradiated by the microwave energy. The microwave antenna is deployed through one of several methods, and multiple curved antennas can be used in conjunction with one another. Moreover, RF energy can also be used at the distal tip of the antenna to provide a cutting tip for the antenna during deployment in tissue.

An apparatus for delivering subcutaneous cavity marking devices. More particularly, the delivery devices may be used with biopsy systems permitting efficient placement of a biopsy marker within a cavity. The device may include an intermediate member which assists in deployment of the marking device. The devices may also include a deployment lock to prevent premature deployment of a biopsy marker. The invention may further include the capability to match an orientation of a biopsy probe which has been rotated upon procurement of a biopsy sample.
