Abstract: Embodiments herein relate to a medical device for treating a cancerous tumor, the medical device having a first lead including a first wire and second wire; a second lead can include a third wire and fourth wire; and a first electrode in electrical communication with the first wire, a second electrode in electrical communication with the second wire, a third electrode in electrical communication with the third wire, and a fourth electrode in electrical communication with the fourth wire. The first and third electrodes form a supply electrode pair configured to deliver one or more electric fields to the cancerous tumor. The second and fourth electrodes form a sensing electrode pair configured to measure an impedance of the cancerous tumor independent of an impedance of the first electrode, the first wire, the third electrode, the third wire, and components in electrical communication therewith. Other embodiments are also included herein.

Abstract: A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.

Abstract: A method for treating an intestine with an expandable scaffolding expanded within the intestine. After placing the expandable scaffolding at a target location, such as across a fistula, the first and second end portions of the expandable scaffolding are radially expanded such that the first and second end portions contact an inner surface of the intestine on opposing sides of the fistula, anchoring the first and second end portions to the intestine. Radially expanding the first and second end portions foreshortens the medial portion along the longitudinal axis such that the first and second end portions are drawn closer together along the longitudinal axis as the medial portion foreshortens to close the fistula.
