20090292241 | BALLOON CATHETER - A catheter arrangement is described that is arranged to permit a guide wire or other structure to be fed laterally from the region of an expandable working element. The catheter includes an elongate flexible tubular member and an inflatable structure carried by a distal portion of the flexible tubular member. The flexible tubular member has a guide wire lumen and at least one fluid supply lumen that is in fluid communication with the inflatable structure. The inflatable structure includes at least one, and preferably two, inflatable members (which may take the form of balloons). In the case of two inflatable members, the first and second inflatable members are radially spaced about the guide wire lumen such that at least one gap is formed between the inflatable members. With this arrangement, the distal end of a guide wire may be advanced through the guide lumen and out of a side opening such that the guide wire passes laterally between the first and second inflatable members. With such an arrangement, a guide wire passing out of the side opening in the region between the inflatable members can readily be directed into a second branch of a vessel bifurcation while the device is positioned in a first branch. | 11-26-2009 |

20110022159 | POROUS MEMBRANES FOR MEDICAL IMPLANTS AND METHODS OF MANUFACTURE - The present invention involves porous polymer membranes, suitable for use in medical implants, having controlled pore sizes, pore densities and mechanical properties. Methods of manufacturing such porous membranes are described in which a continuous fiber of polymer is extruded through a reciprocating extrusion head and deposited onto a substrate in a predetermined pattern. When cured, the polymeric material forms a stable, porous membrane suitable for a variety of applications, including reducing emboli release during and after stent delivery, and providing a source for release of bioactive substances to a vessel or organ and surrounding tissue. | 01-27-2011 |

20110284498 | METHOD OF REDUCING RIGIDITY OF ANGIOPLASTY BALLOON SECTIONS - A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways. | 11-24-2011 |

20130190856 | METHODS AND APPARATUS FOR STENTING COMPRISING ENHANCED EMBOLIC PROTECTION COUPLED WITH IMPROVED PROTECTIONS AGAINST RESTENOSIS AND THROMBUS FORMATION - Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Apparatus and methods are also provided for use at a vessel branching. The present invention further involves porous polymer membranes, suitable for use in medical implants, having controlled pore sizes, pore densities and mechanical properties. Methods of manufacturing such porous membranes are described in which a continuous fiber of polymer is extruded through a reciprocating extrusion head and deposited onto a substrate in a predetermined pattern.
