    摘要： A method for inhibiting hyperplasia at an anastomotic junction of a vascular fistula or vascular graft comprises exposing the anastomotic junction to vibrational energy at a mechanical index and for a time sufficient to inhibit hyperplasia. Kits are described comprising the catheter or a probe suitable for performing the methods together with instructions for use setting forth the methods. The methods and kits are particularly suitable for treating anastomotic junctions formed to provide vascular access for hemodialysis, hemofiltration, and the like. The methods and kits are also suitable for treating other vascular grafts, such as those formed during cardiac bypass graft surgery, vascular repair, and the like.

    摘要： Intravascular catheters including both a flexible catheter body and a less flexible housing mounted at a distal end of the catheter body are provided with a flexible distal tip, preferably having a conical geometry. Guidewire channel or lumen is formed within the tip, and optionally additional guidewire lumens are formed in the housing or the distal end of the catheter body, or both. The catheters may thus be inserted and withdrawn over a guidewire without the need for the entire length of the catheter to pass over the guidewire.

    摘要： An apparatus is provided for forming a tissue tract (8, 11A, 17A) from within a first passageway of an eye (11, 17) connecting to a second passageway in the eye (12, 16) comprising an elongated tool with a proximal end and distal end. The tool has an outer diameter in the range of about 50 to about 1000 microns. Methods of using the tool are provided for creating a fluid path for aqueous humor of an eye from a first passageway of the eye, such as the Schlemm's Canal, to a second passageway, such as the suprachoroidal space

    摘要： The claimed invention provides an improved tracking tip for use with a work element in a catheter system having a flexible tubular catheter body. Use of a tracking tip according to the present invention will facilitate advancement of the work element within the catheter body and will substantially eliminate the possibility that the work element will puncture the catheter body. Preferred embodiments will comprise a wire coil and will often include a rounded end member, which may be in the form of a solder ball, at the distal tip of the wire coil. In some embodiments, the rounded end member may be coated with a lubricant or a suitable non-stick material to further improve tracking of the work element within the catheter body.

    摘要： An injector is provided to deliver microquantities of viscous materials into the body, such as the eye, for surgical purposes. The injector comprises a syringe body with a plunger disposed therein coupled to a positive displacement mechanism capable of progressively advancing the plunger to precisely deliver microquantities of materials at a constant or predetermined delivery rate.
