Disclosed are an imaging system () or an interventional tool, such as a catheter (), having a first ultrasound transducer array () and a second ultrasound transducer array () spaced by a fixed distance (D) from each other; wherein both arrays may be used to generate diagnostic images; and a processing arrangement () to process a first sensor signal indicative of the first array imaging a reference location (X) at a first point in time, and to process a second sensor signal indicative of the second array imaging the reference location at a second point in time; and determine a translation (pullback) speed of the catheter from the set distance and the difference between the first point in time and the second point in time. Alternatively, a catheter may be provided comprising an ultrasound transducer array at a distal end of the catheter, and two pressure sensors for determining the translation speed.

Imaging system and method of determining a translation speed of a catheter

This invention relates to an implantable medical system, where an implantable device including a power source operable connected to electrical components is adapted to generate electrical pulses, and a probe having a distal-end and a proximal-end. The distal-end has one or more electrodes adapted to be in electrical contact with a target tissue and wires for connecting the one or more electrodes to the implantable device. The wires conduct the electrical pulses from the implantable device to the one or more electrodes and into the target tissue. The probe has at least one capacitor and wires for connecting the at least one capacitor to the electrical components in the implantable device such that the at least one capacitor forms a part of the electrical components of the implantable device.

Implantable medical system

The invention relates to an electrical multichannel system () and to a neural stimulation and/or recording device comprising such a system. The multichannel system comprises a plurality of application components (), e.g. stimulation electrodes, and associated access points () that are connected by a plurality of electrical lines (). The resistances of these lines are adjusted to given target values, for example to equal values, by incorporating appropriate tuning sections () into the electrical lines. The lines may for example comprise different geometries and/or materials in the tuning sections.

Electrical multichannel system, particularly for neural stimulation

A thin film for a lead for brain applications includes at least one section comprising a high conductive metal and a low conductive metal, whereby the low conductive metal is a biocompatible metal and has a lower electrical conductivity than the high conductive metal and whereby the high conductive metal is at least partially encapsulated by the low conductive metal. Furthermore, the present invention relates to a method of manufacturing a thin film for a lead for brain applications and a deep brain stimulation system.

Thin film for a lead for brain applications

The present invention regards a probe for deep brain stimulation (DBS), with high overall impedance, but low overall resistance. This is achieved since the probe comprises a structure comprising at least two interconnected spirals, wherein said two spirals have different direction of rotation. A system for deep brain stimulation comprising the probe, a power source and an electrode is also disclosed.

The invention relates to a probe for an implantable electro-stimulation device. The probe () has a distal end () and a proximal end (), and moreover comprises: one or more electrodes () a shield () of conducting material covering a major part of the probe, said shield extending from the vicinity of at least one of the one or more electrodes () towards the proximal end () or towards the distal end () of the probe (); and a layer () of insulating material covering part of the shield () in the vicinity of the at least one of the one or more electrodes. The shield protects wires (), extending from electrodes to the proximal end of the probe, from undesired interference of external RF fields. The exposed part of the shield not covered by the layer of insulating material serves as a return electrode for the electrostimulation signal path.

A lead for use in neural stimulation comprises a core section having a proximal end and a distal end. A plurality of electrodes is coupled to the core section proximate the distal end. At least one contact is coupled to the core section proximate the proximal end. At least one thin film is wound around the core section from the proximal end to the distal end and electrically coupling the at least one contact and the plurality of electrodes. The at least one thin film forms a curved substantially planar shape in a relaxed state before being wound around the core section.

Freestanding thin film for a system for neural applications

The invention relates to a probe () for an implantable medical device. The probe has a distal end () and a proximal end (), and the probe () moreover comprises an electrode () at the distal end. The electrode is connected to a wire () extending from the electrode to the proximal end of the probe, where the resistivity of the wire is non-uniform along the length of the wire. The wire may have high resistivity at the distal end of the probe and low resistivity wires elsewhere. The high resistivity wires reduce the peak current density in the tissue of an implanted device, and thus prevents destructive heating and/or undesired stimulation of tissue during MRI examination. This highly contributes to MR safety which is a highly desired feature for these implantable electrical stimulation devices.
