Abstract: An apparatus for performing a medical procedure including an electrosurgical unit for generating radiofrequency energy, an interventional wire including a distal tip portion configured to deliver the radiofrequency energy to tissue during the medical procedure and an activator to activate delivery of the radiofrequency energy from the electrosurgical unit to the interventional wire. The distal tip portion of the interventional wire includes a core wire in a tubular structure. A distal tip structure or element at the end of the core wire delivers the radiofrequency energy to tissue.

Abstract: An apparatus for performing a minimally invasive medical procedure. The apparatus includes an elongated flexible conductive element, an activator unit, an interventional wire, and an accessory connector. The activator unit is connected to the elongated flexible conductive element and configured to selectively activate the delivery of radiofrequency energy. The interventional wire is electrically connected to the activator unit and configured to deliver radiofrequency energy during the minimally invasive medical procedure. The accessory connector is coupled to the elongated flexible conductive element and configured to connect the elongated flexible conductive element to an electrosurgical unit to deliver continuous, sinusoidal, low-amplitude alternating electrical current from the electrosurgical unit to the elongated flexible conductive element and to the interventional wire.

Abstract: An electrosurgical guidewire including a core wire including a distal core wire portion, a shaft portion, an active electrode, a first electrical insulation material, and a second electrical insulation material. The distal core wire portion is located at a distal portion of the electrosurgical guidewire. The shaft portion is located at a proximal portion of the electrosurgical guidewire and includes an electrical connection portion configured to provide an electrical connection to an electrosurgical generator. The first electrical insulation material has a first thickness covering the distal core wire portion. The second electrical insulation material has a second thickness covering the shaft portion. The first thickness is greater than the second thickness.

Abstract: An electrosurgical guidewire including a core wire. The core wire having a treated segment with an outer surface treated to impart an echogenic texture to the outer surface of the treated segment. The echogenic texture operating to increase ultrasound visibility of the treated segment.

Abstract: An aortic heart valve replacement system includes a prosthetic aortic heart valve and a prosthetic aortic heart valve dock. The prosthetic aortic heart valve is moveable between a collapsed condition for directing the prosthetic aortic heart valve to the location of the patient's natural aortic heart valve and an expanded condition for fixing the prosthetic aortic heart valve at the location of the patient's natural aortic heart valve. The collapsed condition is also used for later explanting the prosthetic aortic heart valve. The prosthetic aortic heart valve dock has a ring structure configured to receive the prosthetic aortic heart valve in the expanded condition and to later release the prosthetic aortic heart valve during explantation. At least one of the prosthetic aortic heart valve or the prosthetic aortic heart valve dock includes one or more stop elements configured to prevent unwanted movement of the prosthetic aortic heart valve.

Abstract: An apparatus for performing a medical procedure including an electrosurgical unit and an assembly including an elongated flexible conductive element, an interventional wire, a coupler, and an activator unit. The electrosurgical unit is configured to generate radiofrequency energy. The elongated flexible conductive element includes a proximal end connected to the electrosurgical unit, and a distal end. The interventional wire is configured to deliver radiofrequency energy. The coupler electrically couples the elongated flexible conductive element to the interventional wire. The activator unit is electrically coupled to the elongated flexible conductive element and is configured to selectively activate the delivery of radiofrequency energy from the electrosurgical unit to the interventional wire.

Abstract: A fill for soft furniture includes a first type of particle for filling the soft furniture and a second type of particle for filling the soft furniture, and the first type of particle is mixed with the second type of particle.

Abstract: A method for verifying the authority of a user to access by a mobile telephone either a payment system or a data system. A user card that carries a microprocessor and a memory that includes an encryption key is inserted into a mobile telephone to initiate a connection with the payment system or the data system via the mobile telephone system network. Using the mobile telephone keypad, the user enters an identifying number that is unique to that user, and the microprocessor performs a calculation using the encryption key and the user identifying number to obtain a calculated signature that is transmitted over the mobile telephone network to a computer connected with the payment system or the data system to which access is desired.
