Abstract: A deflectable, flexible device includes an elongate body, a convoluted tip portion at a distal end of the elongate body, and a lumen to receive one or more wires. The convoluted tip portion includes an electroformed pleated region which is formed by electrodepositing a metal on a mandrel having a pleated region. The convoluted tip portion may be hermetically sealed to permit repeated sterilization. The electroformed pleated region may include one or more fluid emission orifices. The convoluted tip portion extends or bends in response to fluid pressure manipulation, contact with tissue, manipulation with an internal spring or wire, or by a user pushing, pulling, or twisting the catheter directly or via an introducer sheath or the like. The convoluted tip portion may further include an RF ablation element or other energy-driven technique to create continuous linear lesions or a sensing element.

Abstract: A method of manufacturing an ultrasound transducer is provided. The ultrasound transducer is activated and the activity across the transducer is measured to determine whether the activity at any area does not meet an acceptance criteria. The transducer is then modified so that the area meets the acceptance criteria. The transducer may be modified with a laser which removes material from the area which does not meet the acceptance criteria.

Abstract: The invention relates to an ablation catheter which controls the temperature and reduces the coagulation of biological fluids on an electrode of a catheter, prevents the impedance rise of tissue in contact with the electrode, and maximizes the potential energy transfer to the tissue, thereby allowing an increase in the lesion size produced by the ablation. The electrode includes passages positioned to allow saline flow out of an inner cavity of the electrode. This fluid flow is pulsatile to increase turbulence, reducing areas of stagnant flow, and produces a desired cooling effect.

Abstract: An electrophysiology catheter is provided. In one embodiment, the catheter includes an elongate, deformable shaft having a proximal end and a distal end and a basket electrode assembly coupled to the distal end of the shaft. The basket electrode assembly has a proximal end and a distal end and is configured to assume a compressed state and an expanded state. The electrode assembly further includes one or more tubular splines having a plurality of electrodes disposed thereon and a plurality of conductors. Each of the plurality of conductors extends through the tubular spline from a corresponding one of the plurality of electrodes to the proximal end of the basket electrode assembly. The tubular splines are configured to assume a non-planar (e.g., a twisted or helical) shape in the expanded state.

Abstract: A sensing assembly for sensing contact with an object is disclosed. The contact sensing assembly may comprise an elongate tubular body. An electrode may be connected to the elongate tubular body. A vibration element is operatively connected with the electrode and configured to deliver a vibration-inducing signal to induce vibration of the electrode. A sensor is configured to monitor the electrode for a perturbation in the induced vibration. The perturbation results from contact between the electrode and the object.

Abstract: A system for determining a position of a medical device within a body is provided that reduces positional error by establishing a reference origin closer to the device and/or simplifies the system by integrating components and functions. In one embodiment, a pair of drive electrodes are affixed to opposed surfaces of the body and create a pathway for transmission of current through a position sensor related to the medical device. A pair of reference electrodes proximate the drive electrodes are coupled to a common reference node outputting a reference signal establishing the reference origin. An electronic control unit determines the position of the medical device responsive to the position signal and the reference signal. In another embodiment, a patch affixed to an external surface of the body has a base layer and multiple devices supported on the base layer, electrically isolated from one another, and configured to perform different functions.
