  • Publication number: 20130184740
    Abstract: A medical filter has more than one pair of struts extending along an undulating path between a first and second end, which cooperate to define a first and second filter element having a plurality of cells, connected by a central portion with longitudinal strut sections. The struts extend between the first and second ends, and the struts tend to resiliently expand in radially outward directions from a compressed initial shape to an expanded deployed shape. In the expanded shape, the undulating path is defined by (i) a first portion of each pair of ribs extends substantially adjacent to each other for a distance from the first end, (ii) a second portion of each pair of ribs extends substantially adjacent to each other for a distance from the second end; and (iii) an intermediate portion of each one of a pair of ribs extends to curve away from each other.

  • Patent number: 8475405
    Abstract: A balloon catheter for use with an endoscope may have a flexible shaft extending between a proximal and distal end, with a hub affixed to the proximal end, and a balloon that is longitudinally asymmetrical. A balloon may have a central or cylindrical working portion, flanked by proximal and distal tapering portions, which are in turn flanked by proximal and distal balloon legs, which are affixed to the catheter shaft. In more specific detail, a longitudinally asymmetrical balloon may have proximal and distal tapering portions that have a relatively steep and a relatively shallow tapering angle, respectively. An optional additional feature of such a balloon catheter is that the catheter shaft may have a high pull strength and low longitudinal elongation, by including some type of reinforcement.

  • Publication number: 20130144376
    Abstract: A medical device has a structure made of a first biodegradable and/or bioabsorbable material and a second biodegradable and/or bioabsorbable material encapsulating a degradation additive incorporated into the first biodegradable and/or bioabsorbable material. The second biodegradable and/or bioabsorbable material has a degradation rate that is faster than the degradation rate of the first biodegradable and/or bioabsorbable material such that the structure experiences a period of accelerated degradation upon release of the degradation additive following sufficient degradation of the second biodegradable and/or bioabsorbable material.

  • Patent number: 8454673
    Abstract: A balloon catheter or stent delivery system for medical treatment of a patient has a proximal hub, a balloon, and an improved shaft design. The catheter shaft has a rapid-exchange configuration, and a tubular outer body that includes a hypotube extending from the catheter proximal end to a position at or near a proximal leg of the balloon. An inner tubular body defines a guidewire lumen extending from a distal guidewire port at the catheter distal end to a proximal port located at a position between the balloon and the hub. A distal leg of the balloon is directly or indirectly affixed to the inner body, and a proximal leg of the balloon is affixed to the distal end of the outer body. The hypotube has an aperture for accepting the inner body proximal end, and a circumferential cut pattern. The cut pattern adds flexibility, and may extend from the hypotube distal end to a position proximal of the proximal guidewire port.
