  • Patent number: 10537286
    Abstract: A catheter having a distal assembly with multiple spines with proximal ends affixed to the catheter and free distal ends. The spines have different lengths so distal ends of the spines trace different circumferences along an inner tissue surface of a tubular region to minimize risk of vein stenosis. The spine lengths can be configured so that the distal ends trace a helical pattern. The distal assembly may have a plunger which deflects the spines when moved longitudinally relative to the distal assembly. The catheter may include a second distal assembly distal of a first distal assembly wherein the first and second distal assemblies are separated by a fixed distanced or an adjustable distance.

  • Patent number: 10433896
    Abstract: An electrosurgical generator, a control device, a method for operating the electrosurgical generator and a computer program product. The electrosurgical generator includes an ultrasonic generator for providing an excitation signal by which an ultrasonic converter can generate an ultrasonic vibration, a radiofrequency generator for providing a radiofrequency energy at two output contacts, and a control unit adapted to independently activate the radiofrequency generator and the ultrasonic generator. The control unit is further adapted to determine a DC-offset voltage between the two output contacts of the radiofrequency generator, check if the DC-offset voltage exceeds a DC-offset threshold value, and deactivate the ultrasonic generator if the DC-offset voltage does not exceed the DC-offset threshold.

  • Patent number: 10433963
    Abstract: A torque-delivering cable is provided, which includes a first coupling. The torque-delivering cable and the first coupling are shaped so as to collectively define a first passage therethrough. A tissue anchor is further provided, which includes a tissue-engaging element and a second coupling, which second coupling is shaped so as to define a second passage therethrough. The first and the second couplings are interlockingly coupleable to each other. An elongate longitudinal locking element is additionally provided, which is shaped so as to define a sharp tip, and which (a) when reversibly disposed in the first and the second passages, maintains coupling together of the first and the second couplings, and (b) when withdrawn from the second passage, allows decoupling of the first and the second coupling from each another.

  • Patent number: 10405919
    Abstract: Described here are systems and methods for affecting tissue within a body to form a lesion. Some systems comprise tissue-affecting devices, devices that guide the advancement of the tissue-affecting elements to a target tissue region, devices that locate and secure tissue, and devices that help position the tissue-affecting devices along the target tissue. The methods described here comprise advancing a first tissue-affecting device to a first surface of a target tissue, advancing a second tissue-affecting device to a second surface of the target tissue, and positioning the first and second devices so that a lesion may be formed in the tissue between them. In some variations, the devices, systems, and methods described here are used to treat atrial fibrillation by ablating fibrillating tissue from an endocardial surface and an epicardial surface of a heart. Methods of closing, occluding, and/or removing the left atrial appendage are also described.
