Abstract: Discussed herein are various embodiments related to a catheter assembly. The catheter assembly can include a catheter body extending between a proximal portion and a distal portion. The catheter body can include a sleeve and a hypotube, connected by at least one bond site, and separated by a floating gap. The hypotube can include at least one flow opening extending from the hypotube lumen to a stagnation zone, configured to permit flow between the stagnation zone and the hypotube lumen.
Abstract: An intravascular emboli capture and retrieval system for intravascular embolism protection and embolism removal or maceration. Guidewire mounted proximally and distally located multiple opening filters are deployed within the vasculature and used to part, divide and macerate embolic debris and to capture such embolic debris within the confines thereof. A deployable flexible preformed memory shaped capture sleeve is alternatively used to collapse one or more filters and embolic debris therein for subsequent proximal withdrawal from the vasculature.
Abstract: Disclosed herein are a catheter assembly and method of applying a catheter assembly. In an example, the catheter assembly can include a catheter body and frame member extending between proximal and distal portions, the frame member having a first mechanical characteristic, and a floating sleeve coupled around the frame member and extending between the proximal and distal portions, the floating sleeve having a second mechanical characteristic different than the first mechanical characteristic. The floating sleeve can include at least one floating segment and one or more anchor segments along the catheter body. The at least one floating segment of the floating sleeve can be moveable relative to the frame member, and the one or more anchor segments of the floating sleeve can be interconnected with the frame member.
