Abstract: Devices and methods for treating a target site in a body lumen are provided. A medical device includes a stent-like structure including a plurality of scoring and non-scoring filaments interwoven with one another. Generally, the stent-like structure will have more non-scoring filaments than scoring filaments to provide greater structural support and to focus the scoring forces on only a few select areas. The stent-like structure is expanded within the target site to score the target site and to provide temporary structural support while the target site is infused with a therapeutic agent. Such therapeutic agent infusion occurs with the use of a drug eluting or drug coated balloon disposed within the stent-like structure or by occluding the target site and introducing a drug into the occluded target site to sit for a period of time.

Abstract: Devices and methods are described for delivering aneurysm stabilizing substances that may act in more than one pathway to the aneurysmal wall to prevent further enlargement of an aneurysm while allowing blood flow through the treatment area. Methods, devices and features for removal of the delivery device after the treatment are also disclosed.

Abstract: The present invention relates to a catheter apparatus with an anchoring device to stabilize the catheter tip when in use, such as when infusing, injecting, or delivering substances, devices or other catheters into a patient. The apparatus according to various embodiments deploys an anchoring device that stabilizes the catheter tip and enables adjustment of the blood flow during use.

Abstract: A surgical needle having notches in a sidewall with enhanced ultrasound reflectivity is disclosed. Indentations, ridges, projections, overhanging edges, and other structures are formed in the notches to retain small amounts of air or other reflective material as the surgical needle is passed through tissue. The additional amounts of reflective material retained by these structures will significantly enhance the ultrasound reflectivity and enhance the response to ultrasonic probing to provide an enhanced image during needle placement in a medical patient so that the needle may be accurately placed as desired. Alternatively or additionally, the notches are filled with a substance that contains air bubbles suspended in the substance wherein the suspended air bubbles provide the reflectivity enhancement. In both embodiments, the needle will be visible at any angle in which the device is used in a medical patient.

Abstract: The present invention relates generally to a medical device and method of use, and more specifically to a method and apparatus with coaxial components used to treat venous diseases. The apparatus according to various embodiments operates as an inferior vena cava filter, a clot puller, a clot shredder, and as a prosthetic venous valve.
