Abstract: A stent suitable for deployment in a blood vessel to support at least part of an internal wall of the blood vessel comprises a plurality of longitudinally spaced-apart annular elements, and a plurality of connecting elements to connect adjacent annular elements. Each connecting element is circumferentially offset from the previous connecting element. Upon application of a load to the stent, the stent moves from an unloaded configuration to a loaded configuration. In the unloaded configuration the longitudinal axis of the stent is straight, and the stent is cylindrically shaped. In the loaded configuration the longitudinal axis of the stent is curved in three-dimensional space, and the stent is helically shaped.

Abstract: A bristle device for delivery into a body lumen comprises a longitudinally extending stem 1 and a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may be at least two bristle segments and in some cases there are flexible sections between the segments. The flexible sections articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments are spaced-apart to accommodate bending of the bristles.

Abstract: Provided is a device for delivery into a body lumen having a longitudinally extending stem and a plurality of bristles extending generally radially outwardly from the stem. The device includes at least two different groups or types of bristles.

Abstract: A catheter (1) comprises a jacket (20, 33) and defining a lumen, and extends distally towards a tip (30, 31). The catheter has a helical support (20) within the jacket for at least some of the length of the jacket. The catheter distal end has a plurality of portions of different configurations for different bending and/or pushability characteristics. These may be according to different helical supports and the manner in which they are interwoven, and/or different liners with lap joints. There may be a hydrophilic coating.

Abstract: A bristle device 8 for delivery into a body lumen comprises a longitudinally extending stem 1 and a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may be at least two bristle segments 96 and there are flexible sections 95 between the segments 96. The flexible sections 95 articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments 96 are spaced-apart to accommodate bending of the bristles.

Abstract: A catheter has a jacket (10, 11, 5) defining a lumen and a helical support (6). The catheter has a proximal portion (1) and a distal portion (3), the distal portion having for at least some of its length a corrugated outer surface. A transition portion has a flexural stiffness which is less than that of the distal portion and more than that of the proximal portion. The transition portion provides an optimum transition in flexural stiffness by way of features of the jacket including geometry of jacket corrugations (15), or overlapping tubular layers (1073, 1074). The distal end of the distal portion may have an extension of liner material folded over (1072, 1082) to provide a particularly soft tip. In other examples the liner is terminated (763) before the distal tip. The catheter is particularly suited to an aspiration device (1350) with a flow restrictor (1353) and the distal portion distal of the flow restrictor.

Abstract: A medical device suitable for location in a body lumen is movable between a first loaded configuration and a second loaded configuration. The device has an unloaded configuration which is intermediate the first loaded configuration and the second loaded configuration. The device can be a stent for deployment in a blood vessel.
