A clot capture device assists a surgeon or medical technician to directly see a degree of blood displacement and what type of clot is being or has been extracted, and preferably, all on the sterile field at convenient reach and visual observation by the user (physician or technician), and without cessation of a clot removal procedure. Aspirated blood and a retrieved clot or clots are ejected and deposited on a generally horizontally oriented porous filter and / or foraminous strainer in a co-compartment, for separation thereof. The clot or clots stay in the co-compartment atop the strainer / filter, while extracted blood drains into a blood collection compartment below.

Catheter assembly and delivery system. The catheter assembly includes an inner catheter (1000), an inner core tube (2000), and a sealing member (3000). The inner catheter (1000) has an axially extending catheter lumen, and the inner core tube (2000) has an axially extending core lumen and is positioned within the catheter lumen of the inner catheter (1000), with a gap between the outer wall of the inner core tube (2000) and the inner wall of the inner catheter (1000). The sealing member (3000) is provided on at least one of the inner catheter (1000) and the inner core tube (2000) and seals the gap between them. The sealing member (3000) plays a role in sealing the gap between the outer wall of the inner core tube (2000) and the inner wall of the inner catheter (1000) before and throughout the procedure, thereby preventing the sealed gap from communicating the in vivo environment with the outside world and fundamentally resolving the problem of blood leakage. Because the gap is sealed by the sealing member (3000), the difficult air removal procedure that surgeons have to perform before the procedure begins is no longer necessary, making the entire procedure easier and faster.
