LAYERED ELECTRODE FOR AN IMPLANTABLE MEDICAL DEVICE LEAD – 20120046721

Abstract

A medical device lead includes an insulative lead body, a conductor extending through the lead body from a proximal end to a distal end, and an electrode electrically connected to the conductor. The proximal end is adapted to be electrically connected to a pulse generator. The electrode includes a plurality of electrode modules mechanically coupled in a stack of electrode modules. Each electrode module includes a plurality of layers that define substantially similar sized pores such that the stack of electrode modules includes an array of the substantially similar sized pores.

SHIELDING AN IMPLANTABLE MEDICAL LEAD – 20120046722

Abstract

Implantable medical leads are shielded with a braided shield that surrounds an inner layer of insulation. An outer layer of insulation may also surround the shield. The shield is designed with parameters that limit the passage of radio frequency energy, particularly in the magnetic resonance imaging spectrum, to filars that are surrounded by the inner layer of insulation. The braided shield has a plurality of parameters and corresponding ranges. The parameters include one or more of braid angle, wire size, number of wires wound per direction, number of wires in a bundle, wire spacing in an axial dimension, ultimate tensile strength, cross-sectional wire shape, material, and distance from termination to a nearest electrode. Additional parameters of the lead related to the shielding also include one or more of inner insulation thickness, and outer insulation thickness.

MEDICAL LEAD HAVING A BANDSTOP FILTER EMPLOYING A CAPACITOR AND AN INDUCTOR TANK CIRCUIT TO ENHANCE MRI COMPATIBILITY – 20120046723

Abstract

A bandstop filter includes a capacitance in parallel with an inductance and is placed in series with the implantable lead of an active implantable medical device, wherein values of capacitance and inductance are selected such that the bandstop filter attenuates RF current flow at a selected center MRI RF pulsed frequency or across a range of frequencies. The Q.sub.i of the inductor and the Q.sub.c of the capacitor are controlled to reduce the overall Q of the bandstop filter to attenuate current flow through the implantable lead along a range of selected frequencies. In a preferred form, the bandstop filter is integrated into a Tip and/or Ring electrode for the active implantable medical device.

METHOD OF DELIVERING A MEDICAL DEVICE ACROSS A VALVE – 20120046733

Abstract

Devices and methods for treating veins and venous conditions, such as chronic cerebrospinal venous insufficiency, are provided. In one aspect, the disclosed subject matter provides an intraluminal scaffold having a generally tubular body with a lumen defined therethrough, the tubular body having a compressed condition for delivery and an expanded condition for implant within a vessel having a distended portion, at least a length of the tubular body configured to form an enlarged portion in the expanded condition to engage a wall of the distended portion of the vessel. Methods for fabricating and using the scaffold, methods for remodeling a vein, and methods of deploying a medical device in a vessel without negatively impacting the function of a valve of the vessel, are also provided.

METHOD, EVALUATION UNIT AND MEDICAL EXPANSION APPARATUS TO DETERMINE AND INVOICE THE USE OF THE MEDICAL EXPANSION APPARATUS – 20120046963

Abstract

In a method to determine and invoice the use of a medical expansion apparatus provided to a user (in particular a service provider) by an owner (in particular a referring physician), the medical expansion apparatus expanding the functionality of a primary medical apparatus, the following steps can be implemented automatically by an evaluation unit. Data describing the usage of the expansion apparatus and/or measurement signals from which the usage data are derived are received from the expansion apparatus and/or the primary apparatus. The usage data are evaluated to create an invoice, in particular a cost calculation. The invoice is sent to the owner and/or the user, in particular to processing devices and/or program means associated with the user and/or the owner.

Converting Medical Data to a Data Format for Exportation from a Brokerage System – 20120046969

Abstract

A computer-implemented method includes retrieving, by a computer included in a brokerage system for determining real-time availability of medical service providers for consultations with consumers of medical services, medical data records of a consumer requesting a consultation with one of the medical service providers, with the medical data records retrieved from an source external to the brokerage system and formatted in accordance with a first data format; converting by the computer the medical data records retrieved from the source external to the brokerage system from the first data format to a second, different data format for medical data records used in the brokerage system; and exporting, by the computer system, the medical data to a medical data system used by the one medical service provider.
