Patent number: 10939957Abstract: Systems and methods for non-thermal ablation of tissue are provided. A non-implantable minimally invasive system for treatment of tissue in a body via direct current ablation is provided including a catheter, a plurality of electrodes for deployment through the catheter, a power source for applying power to the electrodes, and a fixation element for maintaining the catheter in a treatment position during treatment of the tissue. A minimally invasive method for treating tissue in a body via direct current ablation is provided including inserting a catheter into the body such that a portion of the catheter remains outside of the body, deploying a fixation element to fix the catheter in a treatment position, deploying a plurality of electrodes through the catheter, applying power to the plurality of electrodes, using the electrodes to apply a current to the tissue, and removing the catheter from the body.Type: GrantFiled: October 1, 2018Date of Patent: March 9, 2021Assignee: Prostacare Pty LtdInventors: Tom A. Nelson, Kai Kroll, Benjamin R. Fruland, Michael C. Holtz, Stephen K. Sundquist

Patent number: 10842555Abstract: Systems and methods for non-thermal ablation of tissue are provided. A non-implantable minimally invasive system for treatment of tissue in a body via direct current ablation is provided. A catheter for use in such system is further provided. The catheter includes a tubular body having a proximal end, a distal end, and a tip positioned at the distal end. The tubular body is semi-flexible, bi-directionally torqueable, and chemically resistant. The tubular body includes a plurality of routing holes provided between the proximal end and the distal end for facilitating deployment of electrodes from the tubular body. The tubular body further comprises an inner sheath generally at an interior portion and an outer sheath generally at an exterior portion and being chemically resistant.Type: GrantFiled: August 19, 2009Date of Patent: November 24, 2020Assignee: Prostacare Pty LtdInventors: Michael C. Holtz, Stephen K. Sundquist, Benjamin R. Fruland, Tom A. Nelson, Kai Kroll

Patent number: 10736689Abstract: A non-implantable minimally invasive system for treatment of tissue in a body via direct current ablation is provided. A low-corrosion electrode for use with such system is further provided. In one embodiment the electrode includes a catheter end configured for coupling to a catheter, a tip configured for puncturing the tissue, and a length extending between the catheter and the tip. The length includes an active portion and an insulated portion. The active portion is electrically conductive and is between approximately 3 mm and approximately 12 mm long at an inserted portion of the electrode. The length further comprises an inner core formed of a material having a high resistance to deformation and an outer shell formed of a material having a high resistance to material decomposition.Type: GrantFiled: August 19, 2009Date of Patent: August 11, 2020Assignee: Prostacare Pty LtdInventors: Stephen K.
