Abstract: A catheter deploys a flexible electrode that is at least partially made of preformed hydrogel to a target location in order to provide radiofrequency catheter ablation. The catheter stores the flexible electrode, which can be deployed and retracted. The preformed hydrogel is conductive and thus can provide an interface between a conductive metal wire and a target cardiac tissue. Electric energy is applied to the portions of the cardiac tissue target tissue that are the genesis of the errant and abnormal heartbeats via the flexible electrode. The electric energy may create lesions with lower risks of steam pops and tissue perforation.

Abstract: A surgical cutting device for performing a minimally-invasive surgical procedure and which includes an external hub including a housing and a cutter actuator housed within the housing, wherein the cutter actuator, a catheter including a first end coupled to the external hub, a second end opposite the first end, and an internal passage, a cutting tool coupled to the second end of the catheter and including a cutting element moveable relative to the second end of the catheter by the cutter actuator, and a motion transfer assembly extending through the internal passage of the catheter from the cutter actuator to the cutting tool, wherein the motion transfer assembly is configured to transfer motion from the cutter actuator to the cutting element of the cutting tool in response to the activation of the cutter actuator.

Abstract: The present invention is a touchpad that interprets not only non-palm contact, but also palm contact, as intentional input, enabling an efficient functional integration, not previously possible, of a touchpad and a keyboard by interpreting palm contact as the pressing of a virtual key.
