    摘要: Embolic protection elements are integrated with a catheter or access sheath for any catheter. A catheter with an integrated embolic protection element comprises a catheter shaft, an embolic filter slidably mounted on a distal portion of the shaft, a proximal stop for limiting the proximal movement of the embolic filter, and a distal stop for limiting the distal movement of the embolic filter. The filter comprises a porous mesh material defining a collection chamber for captured emboli and has a collapsed and a deployed configuration. The filter may be collapsed by an access sheath used with the catheter. An access sheath may comprise a tubular main body and an embolic filter mounted on the distal portion of the tubular main body. The embolic filter may evert into the central lumen of the sheath or may be constrained on the exterior of the sheath with a larger diameter outer tube.

    摘要: A medical device to be inserted into a blood vessel for effectively removing an object flowing in a biological lumen while reducing the burden on the living body includes an elongated shaft portion, and an expansion portion which is an elastically deformable cylindrical body having a plurality of gaps and in which a proximal portion or a distal portion of the cylindrical body is interlocked with the shaft portion. The expansion portion has a ring-shaped or annular bent portion which protrudes toward a proximal side position radially outside the expansion portion in a bent state of being bent along an axial direction, and an axial length of a second portion from the bent portion to a proximal end of the expansion portion is shorter than an axial length of a first portion from the bent portion to the distal end of the expansion portion.

    摘要: A filter assembly and methods of using the filter assembly are disclosed. The filter assembly includes a proximal portion including support members and a distal portion including a mesh. The filter assembly may also include additional portions including additional meshes or support members. The proximal portion of the filter has a first major diameter, and the distal portion of the filter has a second major diameter. In a first unconstrained state, the second major diameter of the filter is less than the first major diameter of the filter. According to certain aspects of the disclosure, the filter assembly further includes a filter wire and a tubular member that may be attached to a proximal or distal end of the filter.

    摘要: A mechanical thrombectomy device system is disclosed that is made from a single piece of biocompatible material, including a proximal flow block portion/feature, and/or, a flow block feature in the device body portion, a guidewire like delivery portion and an expandable, treatment portion. The construction of the device from a single piece allows for a seamless transition from the delivery portion to the treatment portion, thus removing any joints or bonding of the two portions together as separate pieces. This improves the strength of the system as a whole and greatly reduces the possibility of the two parts unintentionally detaching from each other. Likewise, the distal treatment portion is cut from a piece of material the same size as the proximal delivery portion, allowing the device to be compacted to a similar size profile giving it delivery advantages including a lower delivery force required and requiring small access systems, and the treatment portion's surface can be altered to enhance embolus affinity by either coating with a substance or changing the texture by mechanical or chemical means.
