Abstract: A microcatheter and guidewire system for use in tortuous regions of a vasculature includes a catheter body (14) having a distal end, a guidewire lumen (54), a proximal region (16) with an outer diameter. The ratio of the proximal region (16) outer diameter to the distal region (22) outer diameter is at least 1.625:1 to improve pushability of the catheter body (14). The guidewire lumen (54) defines a stopper (50) and the guidewire (12) has a depth stop (42) for engaging the stopper (50) of the guidewire lumen (54). The depth stop (42) and the stopper (50) cooperate to enable the guidewire (12) to cooperate with the catheter (14) to improve catheter (14) pushability. The depth stop (42) and the stopper (50) also prevent over extension of the guidewire (12).

Abstract: A liquid embolic delivery system is provided for trapping an injected liquid embolic composition to prevent the liquid embolic from solidifying or otherwise passing outside of an embolization area. The delivery system includes a catheter for delivery of a liquid embolic composition and a containment member positioned at a distal end of the catheter which is shaped to trap the liquid embolic composition delivered through the lumen of the catheter. The containment member is formed as a brush, nest, sponge, swab, flexible sack, or other shape into and around which the liquid embolic composition is injected. The liquid embolic composition is trapped or meshes with the containment member during solidification containing the liquid embolic and preventing the embolic composition from passing into the blood stream.
