Abstract: A retrieval device may have a contracted state and an expanded state. The retrieval device may include a sheath and at least three support members. Each of the support members may have a first portion with a first cross-sectional shape and a second portion with a second cross-sectional shape different from the first cross-sectional shape. A proximal end fixed of each of the support members may be coupled to the sheath, and a distal end may be movable relative to the sheath. The retrieval device may further include at least three movable members movable relative to the support members. Each movable member may extend through a lumen of one support member of the at least three support members and through a lumen of a different support member of the at least three support members.

Abstract: An endoscopic system includes an endoscopic imager configured to capture image frames of a target site within a living body and a processor configured to apply a spatial transform to a preliminary set of image frames, the spatial transform converting the image frames into cylindrical coordinates; calculate a map image from the spatially transformed image frames, each pixel position in the map image being defined with a vector of fixed dimension; align a current image frame with the map image and apply the spatial transform to the current image frame; fuse the spatially transformed current image frame to the map image to generate a fused image; and apply an inverse spatial transform to the fused image to generate an enhanced current image frame having a greater spatial resolution than the current image frame. The system also includes a display displaying the enhanced current image frame.

Abstract: Embodiments herein relate to systems and methods for intravascular lesion disruption. In an embodiment, a catheter system for imparting pressure to induce fractures upon a vascular lesion within or adjacent a blood vessel wall is included. The system includes a catheter configured to advance to a vascular lesion, the catheter including an elongate shaft that defines at least a first orifice for fluid flow; a balloon, coupled to the elongate shaft, that surrounds the first orifice where the balloon can expand from a collapsed configuration suitable for advancing the catheter through a patient's vasculature to a first expanded configuration suitable for anchoring the catheter in position relative to a treatment site; and a propulsion system configured to propel a fluid from the first orifice toward the balloon wall to create an inertial impulse in a vessel wall to transfer momentum to the vascular lesion. Other embodiments are also included herein.
