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.

摘要： A vein removal device includes a housing, a blade element disposed at least partially within the housing, and a hook element disposed at least partially within the housing. A cutting edge of the blade element is selectively exposed for making an incision in a patient. The blade element is disposed at one end of the housing and the hook element may be disposed at an opposite end of the housing. The blade element may be selectively exposed via actuation of a first user input that imparts a movement of the blade element relative to the housing and towards an extended position where the cutting edge of the blade element is exposed. The blade element may be biased toward the extended position via a biasing element, which may urge the blade element toward the extended position responsive to actuation of the first user input.
