  • Publication number: 20240131679
    Abstract: Disclosed is a foldable workbench (100) with a simple push and pull mechanism for opening and closing of legs without compromising on quick opening and folding performance. The leg opening and closing mechanism of workbench (100) is provided without rack and pinion gears, belt and pulley system or complex linkages with bearings, etc. A simple pulling and pushing action of a handle extends and retracts the first and second pair of legs (20A, 20B) to open and close.

  • Publication number: 20230338048
    Abstract: Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.

  • Patent number: 11690741
    Abstract: Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

  • Publication number: 20230131648
    Abstract: A clot retrieval device featuring a capturing basket coupled to a delivery shaft. The capturing basket is deployable to the side of a clot in a blood vessel. The capturing basket is configured to allow for the clot to ingress into the capturing basket and surround at least a portion of the clot. The capturing basket can be torqued by torquing at the proximal end of the catheter resulting in the rotation of the capturing basket about its longitudinal axis.

  • Publication number: 20220202430
    Abstract: A clot retrieval device is provided. The clot retrieval device includes a capturing basket having an opening at a proximal end where the capturing basket is deployable downstream from a clot in a blood vessel. The capturing basket is configured to surround a portion of the clot and the opening in the proximal end of the capturing basket is configured to reduce in size such that the capturing basket conforms around the portion of the clot and be retrieved after the capturing basket conforms around the portion of the clot.

  • Publication number: 20170156744
    Abstract: Catheters of the present disclosure include a catheter shaft and an expandable tip, which can retrieve materials slightly larger than an inner diameter of the catheter shaft. The tip may be expandable such that it can easily transform from a first size and shape to a second size and shape to aid in the retrieval of the materials (i.e., the thrombus, embolus, or foreign body). Catheter tips may be expanded by inflation, removal of a constraining member, or an input such as heat, light, or electrical energy.
