A system for ablation is described herein including an inner electrode assembly with an inner elongate shaft and a distal electrode, an outer electrode assembly having an outer elongate shaft and a proximal electrode, wherein the outer electrode assembly defines a central passage configured to slidably receive the inner electrode assembly, wherein the distal electrode or the proximal electrode is axially moveable with respect to the other, and an energy source configured to be electrically connected to the distal electrode and the proximal electrode and configured to deliver a pulsed electric field (PEF). One of the distal electrode and proximal electrode is part of a first expandable electrode array comprising two or more electrode elements moveable between an unexpanded position and an expanded position.

Movable electrodes for controlled irreversible electroporation ablative volumes

Methods and devices for performing ablation using time multiplexed waveforms are disclosed. The increased efficacy of monophasic waveforms is combined with the reduced side effects of biphasic waveforms by distributing components of the waveform across over a broader time interval than that typically used in a conventional biphasic waveform. Charge balancing occurs upon completion of therapy delivery within a time period that avoids muscle stimulation, while allowing unbalanced waveforms to be delivered during stimulation.

Time multiplexed waveform for selective cell ablation

An antenna for electrical coupling to a wireless communication circuit includes a first conductive strip segment having a first length, a second conductive strip segment having a second length different from the first length and coupled to the first conductive strip segment at a feed point to be electrically coupled to the drive node, and a third conductive strip segment having a third length less than both the first length and the second length. A first end of the third conductive strip is coupled to the feed point and a second end is coupled to circuit ground. The first conductive strip segment provides a first specified operating frequency range at a fundamental resonance mode corresponding to the first length plus the third length, and the second conductive strip segment provides a second specified operating frequency range at a fundamental resonance mode corresponding to the second length plus the third length.

Ablation probes and methods of their use. Example probes include probe circuits configured to provide identifying information for the probe itself. The probe circuits may sense probe usage and/or age to determine probe end of life (EOL). In response to EOL, the probe circuit generates an output indicating EOL. The probe electronic circuit may also be configured to monitor probe usage via impedance or other features, independent of such operation by an ablation pulse generator.

Smart probe identification for ablation modalities

One general aspect includes a system for ablation including a catheter including a sheath defining a sheath lumen and a distal end, and an elongate electrode assembly axially moveable within the sheath lumen. The electrode assembly includes a shaft defining a central channel and a distal central channel opening. The electrode assembly also includes an expandable electrode array including two or more electrode elements positioned at the distal portion of the electrode assembly, where the electrode array is moveable between a retracted position contained within the sheath lumen and an expanded position protruding from the sheath.

Electrosurgical generators having improved functionality and user interface. In an example, the user may modify therapy output parameters without interrupting therapy delivery within a therapy regimen. In an example, the display shows both therapy amplitudes and encountered impedances for a plurality of therapy pulses in different portions of a display. In an example, the electrosurgical generator is operable in a triggered mode using a cardiac signal trigger and provides the operator with an estimate of remaining time that is calculated in light of a calculated cardiac rate.

Control system and user interface for an ablation system

No-matching-circuit multi-band diversity antenna system for medical external communications

A system and method for providing automatic setup of a remote patient care environment. Connectivity to a centralized server over a network connection is confirmed. Data reporting for a patient by one or more monitoring devices that are wirelessly connectable is induced through control provided through a user interface. Each of the devices is registered as the device attempts to establish a wireless connection and report the data conditioned on permission for access. Upon granting of the permission for access, the device is wirelessly connected and the data is subsequently received over the wireless connection.

A planar antenna for wireless information transfer can include a planar loading portion electrically coupled to a driven node of a wireless communication circuit, and a folded conductive strip portion coupled to the planar loading portion, the folded conductive strip portion comprising at least two segments laterally offset from each other and at least partially laterally overlapping with each other. The planar loading portion can be configured to establish a specified bandwidth of a second operating frequency range, leaving a first specified operating frequency range substantially unchanged.

Apparatus and techniques can include a planar antenna that can include a folded conductive strip portion coupled to a driven node of a wireless communication circuit, the folded conductive strip portion comprising at least two segments laterally offset from each other and at least partially laterally overlapping with each other, and a first region oriented along a first axis in a plane of the planar antenna and a second region oriented along a second axis in the plane of the planar antenna, the two axes and the two regions specified to provide polarization diversity of radiation from the planar antenna. The planar antenna can include a stub coupled to the folded conductive strip portion, the stub configured to provide a first specified operating frequency range at or near resonance using a mode corresponding to a total physical path length along the folded conductive strip portion.

An integrated system for tracking assets (tools and materials) and personnel associated with a work site. Personnel are equipped with tracking devices having at least geolocation capability. Assets are tagged with RFID tags, which are interrogated at portals, by mobile scanners, or by personnel tracking devices having RFID reading capability. The tag readers and tracking devices are all in communication with a common 'information backbone' and all data is delivered to, and processed by, a common command and control subsystem.
