Abstract: Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.

Abstract: A catheter includes an elongate catheter body configured for insertion into a body lumen of a subject. A cutter is located generally at a distal end of the catheter body for rotation generally about a longitudinal axis of the cutter. An eccentric opening in a distal end portion of the cutter defines an angled cutting edge for cutting material from a wall of the body lumen. A center of the opening is offset from the longitudinal axis of the cutter. A cavity extends from the opening through the cutter from the distal end portion to a proximal end portion to allow material cut by the cutter to pass through the cutter into an interior passage of the catheter body for removal from the body lumen.

Abstract: Drive shafts having helical blades and methods of making are disclosed. In one method a helical auger blade is formed by twisting or sculpting a heated polymer tube which has been placed over a cylindrical drive shaft. In another method a drive shaft is placed within a helical winding and heat is applied to melt polymer which has been coated over one or both of the drive shaft and helical winding.

Abstract: A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element includes a cutting edge that extends around the axis of rotation and a depth stop that extends around the axis of rotation radially inward of the cutting edge relative to the axis of rotation. The depth stop defines an engagement surface adapted to engage a hard object and thereby limit the depth at which the cutting edge cuts into the hard object. In use, when the cutting edge cuts into a hard object, the depth stop engages the hard object to limit the cutting depth.

Abstract: A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element is, in some embodiments, an integrally formed one-piece body. The tissue-removing element has a tissue-removing head that includes a plurality of shearing members spaced apart around the axis of rotation. Channels separate the plurality of shearing members and extend through the radially outer surface of the tissue-removing head. In some embodiments, the shearing members include respective wedge portions that hook and cleave tissue as the tissue-removing element rotates.

Abstract: A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element is an integrally formed, one-piece body and has an annular tissue-removing head at the distal end of a tissue-removing element body. In some embodiments, primary tissue-removing components include an integrally formed cutting tooth and inner shearing member and are spaced angularly around the tissue-removing blade. Secondary tissue-removing components include cutting teeth and are interposed between the primary tissue-removing components around the tissue-removing blade. The tissue-removing element is made by removing material from a blank to form the primary and secondary tissue-removing components.

Abstract: A tissue-removing catheter includes a tissue-removing element operatively connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. A tissue-removing head of the tissue-removing element defines an annular cutting blade. In some embodiments, angularly spaced cutting teeth form the cutting blade. Inner shearing members extend radially inward from the cutting blade. As the tissue-removing element rotates in the cutting direction and advances axially through a body lumen, the annular cutting edge separates the tissue from the body lumen wall. Leading surfaces of the inner shearing members shear the separated tissue radially inwardly. In some embodiments, the tissue-removing element is an integrally formed, one-piece body made by removing material from a blank to form the cutting blade and inner shearing members.
