The invention relates to methods of transvascular retrograde access placement into a central blood vessel and to devices that facilitate these methods. The method includes positioning a vascular catheter within the vessel such that its distal end faces a desired exit site on the vessel wall, passing a penetrating device from the catheter through the vascular exit site and skin of the patient; and passing a secondary vascular catheter through the exit site and into the central blood vessel. In another aspect, the method includes penetrating outward from within the vessel to form a pass-through site on a wall of the vessel that exits the patient; and placing the vascular access device into the vessel through the pass-through site. Typical vessels that may be accessed include central veins, but may include other veins as well as arteries. Devices that facilitate the method include a stiff intravascular guidewire with a distally-mounted penetrating device such as a needle, and a two-channel vascular catheter with an angled tip.

A microfluidic flow cytometry device includes a substrate and transverse electrodes formed on the substrate. An elastomer microfluidic focusing channel system formed on the substrate focuses a sample stream onto the floor of an outlet channel that is substantially wider and taller than cells or particles of interest and that has the transverse electrodes disposed in its floor upstream of an exit site. A step in the outlet channel upstream of the transverse electrodes vertically confines sample stream flow onto the floor of the outlet channel over the transverse electrodes. Buffer inlet channels introduce a buffer stream for horizontal focusing of the sample stream into the central region of the outlet channel at the transverse electrodes. A sample inlet channel is smaller in vertical height than the buffer inlet channels for introducing a sample stream such that the buffer vertically focuses the sample stream away from the top of the outlet channel. Sensitivity of detection is good enough to conduct both qualitative and quantitative analysis. Detection and analysis circuitry can be optimized to conduct analyze real and imaginary impedance at frequencies optimized toward tagged particles and or cells, and assays are possible.

A method for occluding a body vessel in a patient to block or reduce blood flow therethrough includes puncturing a blood vessel wall at a proximal vessel entry site with a hollow needle and extending the needle through the proximal entry site into the vessel lumen. The needle is extended through the vessel lumen and extended through the vessel wall at a distal vessel exit site into the extravascular space surrounding the distal vessel exit site. An expandable biocompatible material, such as expandable extracellular matrix (ECM) material, is then ejected though the distal end of the needle into the extravascular space. Then, while continuing to eject the expandable biocompatible plug material, the distal end of the needle is retracted back through the distal vessel exit site into the vessel lumen, such that the plug material continuously extends between the extravascular space surrounding the distal vessel exit site into the vessel lumen. When the plug material is delivered into the lumen of the vessel, the plug material expands, anchoring the plug material to the vessel wall, whereby the plug material forms an occluding plug in the vessel lumen blocking or reducing blood flow therethrough.
