A crossflow filter includes a rigid cylindrical inner wall and a rigid cylindrical outer wall with an inelastic filter membrane positioned therebetween defining a retentate channel inside the filter membrane and a permeate channel outside the filter membrane. Further, the filter includes transition channels shaped and connected to the inner and outer walls to deliver a flow of fluid from an inlet port to the retentate channel and to capture flow flowing longitudinally along the cylindrical inner and outer walls from both the retentate and permeate channels to respective outlet ports.

Systems, methods, and devices for removing circulating tumor cells from blood

Filtering systems, methods, and devices, particularly adapted for apheresis of cellular bodies and more specifically for apheresis of circulating tumor cell bodies (CTCs) employs a cross-flow channel. Systems and methods as well as devices for such a system are described. Embodiments include a cylindrical filter that employs a thin micro-machined porous filter membrane with a regular array of pores and reliably pass blood while trapping CTCs.

A thermal ablation system comprises a fluid handling unit receiving fluid from a fluid source at a first pressure, the fluid handling unit including a heater heating the fluid to a desired temperature and a pump and an introducer including a sheath which, when in an operative position, is received within a hollow organ, the sheath including a delivery lumen introducing fluid heated by the heater to the hollow organ and a return lumen withdrawing fluid from the hollow organ and returning the withdrawn fluid to the console via a return lumen, wherein the pump increases a pressure of the fluid between the fluid source and the delivery lumen of the introducer.

Thermal ablation system

A system is for thermal ablation and includes (a) a heating element heating an ablation fluid flowing through an ablation device and to a target region of a body and (b) a computing arrangement controlling power supplied to the heating element supplying power to heat the ablation fluid to a desired temperature. The computing arrangement reduces the supplied power when a detected ablation fluid temperature exceeds a desired temperature and increases the supplied power when the detected ablation fluid temperature is below the desired temperature. The computing arrangement monitors a percentage of heat supplied by the heating arrangement to heat the fluid to the desired temperature as a function of a maximum amount of heat which the heating element is capable of supplying.

Indirect fluid flow measurement

Apparatus for measuring an amount of ablation fluid circulating in a system for ablating tissue comprises a plurality of electrical contacts located within an ablation fluid receiving chamber of the system, the contacts being located at various heights and a data processing arrangement coupled to the contacts to receive data corresponding to electrical conductance between pairs of the contacts, the data processing arrangement determining a height of fluid in the chamber based on the measured conductance levels and determining based on the determined height, whether an amount of fluid circulating through the system is within a desired range.

HTA fluid level and fluid type measurement

An apparatus for treating tissue, comprising a sheath defining a lumen sized and shaped to receive a treatment device therein, a guide member coupled to the sheath and extending a predetermined distance substantially parallel to a longitudinal axis of the sheath, and a stabilizer element for engaging an anchoring device coupled to tissue to stabilize the sheath and the treatment device, the stabilizing element being movably coupled to the guide member for movement therealong substantially parallel to the longitudinal axis of the sheath wherein, when in a proximal-most position, the stabilizer element is located proximally of a proximal end of the guide member.

Tenaculum stabilizer device

A method for ablating tissue comprising controlling a heating element using a variable phase angle control to heat an ablation fluid to a desired temperature and determining a heating percentage corresponding to a percentage of a maximum available heating power represented by a current level of power supplied to the heating element and, when the heating percentage remains below a threshold level for a predetermined period of time, indicating a flow obstruction condition of the fluid.

A material is provided that uses controlled electrical current derived from dissimilar galvanic materials to drive oligodynamic metal ions into solution.
