Disclosed herein are devices, systems, and methods for monitoring a formation of an iceball at a cryoablation needle. An example method includes receiving an impedance from at least one electrode in an electrode arrangement that is disposed at a cryoablation needle distal portion. The electrode arrangement is configured to engage the iceball as the iceball is formed over the cryoablation needle distal portion so as to cause a change in the impedance. The example method includes determining one or more physical attributes of the iceball based on a rate of the change in the impedance.

Cryoablation iceball formation monitoring devices, systems, and methods

The present invention provides a microwave ablation probe comprising an antenna including a helical arm and a linear arm.

Tissue ablation device with broadband antenna

The disclosure provides a cooling system for a surgical ablation device, the device having a cooling circuit comprising a device coolant supply line having a supply coupling; a coolant return line having a return coupling; coolant passageways within the device to circulate coolant within the device, the supply line and the return line being in fluid communication via the device coolant passageway(s); a coolant manifold configured to fluidly connect a cooling fluid source to at least one manifold fluid outlet port, such as to place the cooling fluid source in fluid communication with the one or more device coolant passageways, wherein the supply coupling is configured for connection to a manifold outlet port of the manifold.

Cooling system for surgical device

A cryoprobe is disclosed comprising a probe shaft made of a low magnetic susceptibility material and an electrical resistance heater comprising counter-wound helical coils located within the probe shaft. The counter-wound helical coils are formed by a single wire counter-wound to form a first set of coils wound in a direction counter to a second set of coils, such that when current is supplied to the electrical resistance heater, a first magnetic field generated by the first set of coils is opposite to a second magnetic field generated by the second set of coils. The electrical resistance heater can heat, thaw, and/or cauterize tissue. The electrical resistance heater can be made of a low magnetic susceptibility material so as to resistively heat tissue concurrently during magnetic resonance imaging (MRI). A method of electrically heating a tissue in conjunction with MRI, and a method of imaging a cryoprobe using MRI is also disclosed.

Cryoprobe for magnetic resonance imaging

A cryoneedle comprises an outer tube having a distal section with a generally central gas supply line placed within the outer tube. The gas supply line supplies a cryogas for forming an iceball on an outer surface of the outer tube over the distal section. The gas supply line terminates in an expansion chamber placed within the distal section. The cryoneedle comprises a heat exchange helix contacting the inner surface of the outer tube. The heat exchange helix has an increasing surface area per unit distance of the distal section such that the iceball has a generally symmetric shape.

Cryoneedle

A medical device including elongate probe defining proximal and distal ends and a thermally-transmissive region at its distal end, the elongate probe including a first fluid supply line in fluid communication with the thermally-transmissive region. A second fluid supply line is provided in fluid communication with the thermally-transmissive region, the second fluid supply line being connected to the elongate probe separately from the first fluid supply line. An exhaust line in fluid communication with the first and second fluid supply lines.
