摘要： A device for crossing a lesion in a tissue lumen includes a crossing wire configured to pass through a lumen of a catheter, the crossing wire including a loop at a distal end of the crossing wire. The loop can have a configuration that prevents a width of the loop from exceeding a width of the tissue lumen, and the loop having a pair of lateral opposing portions configured for alignment with a wall of the tissue lumen and a leading portion interconnecting the pair of lateral opposing portions, the leading portion being configured to interrogate the lesion. The loop has a length in an axial direction of the crossing wire extending from the leading portion to proximal ends of the pair of lateral opposing portions, the length being perpendicular to the width, and the length of the loop is at least twice the width of the loop.

摘要： A peripheral vascular filter according to some aspects of the invention includes a filter body forming a cavity therein, the filter body having a proximal end and a distal end in a length-wise direction of the peripheral vascular filter, the filter body having an opening in the proximal end thereof; a spring system arranged proximal to the filter body and in mechanical connection with the filter body and with a filter wire, the spring system being stretchable along the length-wise direction; a plurality of retractor wires, each retractor wire having a distal end connected to the filter body, and a proximal end connected to spring system. In a deployed configuration, the spring system absorbs forces applied to the filter wire proximal to the filter body to prevent the peripheral vascular filter from becoming dislodged from a position in a peripheral vasculature.

摘要： A device and method for delivering a drug from inside a body lumen to tissue surrounding the body lumen. An endoluminal drug delivery device includes a dual-lumen catheter for housing a guidewire and a needle connectable to a drug source. The guidewire exits the catheter through an opening at the distal end, and the needle exits the catheter through an exit port in the outer wall of the catheter. A distal portion of the catheter has a single lumen and includes a taper, allowing the distal tip to act as a dilator. The device optionally includes a catheter lumen splitter and/or a handpiece assembly. A method of delivering fluid to tissue surrounding a body lumen includes inserting a guidewire into the body lumen, tracking the device over the guidewire, deploying the needle through the exit port to the tissue, delivering fluid, and retracting the needle into the catheter.
