20090197406 | SEQUENTIAL DEPOSITION OF TANTALUM NITRIDE USING A TANTALUM-CONTAINING PRECURSOR AND A NITROGEN-CONTAINING PRECURSOR - Embodiments of the invention provide a method for forming tantalum nitride materials on a substrate by employing an atomic layer deposition (ALD) process. The method includes heating a tantalum precursor within an ampoule to a predetermined temperature to form a tantalum precursor gas and sequentially exposing a substrate to the tantalum precursor gas and a nitrogen precursor to form a tantalum nitride material. Thereafter, a nucleation layer and a bulk layer may be deposited on the substrate. In one example, a radical nitrogen compound may be formed from the nitrogen precursor during a plasma-enhanced ALD process. A nitrogen precursor may include nitrogen or ammonia. In another example, a metal-organic tantalum precursor may be used during the deposition process. | 08-06-2009 |

20150073514 | Endovascular Catheters with Tuned Control Members and Associated Systems and Methods - Endovascular catheters and control wires for operating the catheters and associated systems, apparatuses, and methods are disclosed include a catheter apparatus having an elongated shaft, a therapeutic assembly at a distal portion of the shaft, and a handle at a proximal portion of the shaft. An actuator is located at the handle and operably coupled to the therapeutic assembly via a tuned control member extending through the shaft. The tuned control member includes a control wire and a tuning component attached to one another within the shaft. The tuned control member is configured to achieve a desired tuned force-displacement response by modifying the stress-strain response that a non-tuned control wire would ordinarily provide without the intervening tuning component. | 03-12-2015 |
20150250981 | CATHETERS WITH ENHANCED FLEXIBILITY AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS - A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes two or more first cut shapes and two or more second cut shapes along a helical path extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions. | 09-10-2015 |
20150305808 | DEVICES, SYSTEMS, AND METHODS FOR MONITORING AND/OR CONTROLLING DEPLOYMENT OF A NEUROMODULATION ELEMENT WITHIN A BODY LUMEN AND RELATED TECHNOLOGY - The present disclosure relates to devices, systems and methods providing evaluation and feedback to an operator of a device providing neuromodulation treatment, such as modulation of renal nerves of a human patient. In one embodiment, for example, a system monitors parameters or values generated before treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of various electrical properties associated with an electrode carried by a catheter. The electrode measures an electrical property of biological material making contact with the electrode while deploying the electrode, the electrical property being dependent on a ratio of a wall-interface area to a fluid-interface area. | 10-29-2015 |
