An implantable medical device such as a filter has a generally conical shape formed by a set of filter legs extending from a free distal end to an apex of the assembly and specifically to a coupling device. A retrieval element such as a hook extends from the hub of. A spacer member is disposed at the hub and is formed of a plurality of curved wire elements. The spacer member has a radius or width smaller than the greatest radius of the filter device, defined by the free ends of the filter legs. The spacer member allows the filter assembly to tilt within a vessel but limits the tilt to a maximum desired or permitted tilt, ensuring that the retrieval device remains spaced from the vessel wall and therefore not subject to tissue ingrowth.

The disclosure provides an implantable medical device comprising a material capture element, which has a generally closed conical deployed shape and a narrow end disposed at or proximate the first end of the device. The material capture element includes a wide end facing the second end of the device, the material capture element having a zone of wider radial dimension which provides a first vessel contact site. A plurality of wire tethers are coupled to the wide end and extend to the second end. The wire tethers define a substantially open passageway for blood and provide a second vessel contact site. The first and second contact sites are spaced longitudinally from one another to provide stability. A first retrieval element is disposed at the first end and coupled to the narrow end, while a second retrieval element is disposed at the second end and coupled to the wire tethers.

A thrombus removal apparatus () includes a catheter () having at its distal end () a solenoid coil section () within which there is disposed a piercing element () made of electromagnetic material. Within the solenoid coil section () there is provided a solenoid coil () which can be powered to generate an electromagnetic field which causes the piercing element () to reciprocate into and out of the coil section (), in practice to pierce into and fragment a thrombus disposed in a patient's vessel. An aspiration unit may be provided for aspirating thrombus fragments into the assembly () for removal from the patient's vasculature. The apparatus () is able to remove dense thrombus material from within a patient, which cannot be otherwise removed by means of thrombolytic agents.

An armature assembly comprising an armature body and a number of armature ring segments mounted on the armature body, wherein the armature assembly comprises a number of insertion interface elements and a number of complementary receiving interface elements for mounting an armature ring segment onto the armature body; whereby an insertion interface element is realized to engage with a complementary receiving interface element in a direction essentially parallel to a rotation axis of the armature; and wherein an insertion interface element is formed as an integral part of the armature body or as an integral part of an armature ring segment. A method of assembling an armature is also described, and a wind turbine comprising such an armature assembly is provided.

A stent, for example, is provided with a plurality of frame elements, which may have an undulating form. The stent is provided with a plurality of magnetic elements between adjacent stent elements. The magnetic elements on opposing circumferentially facing portions or sides of the strut elements have the same polarities so as to produce repulsive forces biasing the stent structure into a radially expanded configuration. The magnetic elements provide an alternative opening force on the stent, enabling the stent to be made of struts of thinner and weaker material or of a non-sprung material. The magnetic elements also provide a constant opening force in order to retain the stent reliably in position within a vessel. The stent could be made of a biodegradable material.

A magnet loading apparatus for loading magnet pole pieces onto a field of an electric machine is described. The apparatus includes positioning means realized to hold a magnet pole piece of a plurality P of magnet pole pieces in place relative to its designated position on the field; and a transfer means realized to simultaneously transfer a plurality P of magnet pole pieces from the positioning means onto the field of the electric machine. Also described is a method of loading magnet pole pieces onto a field of an electric machine.
