20090254064 | WEEPING BALLOON CATHETER - Multiple-balloon catheters, and methods of treatment therewith, are provided including an inflatable inner balloon at least partially enclosed by an expandable outer balloon that has holes. The annular space between the inner balloon and the outer balloon is configured to promote delivery of the fluid evenly through holes in the outer balloon to avoid problems of underloading and/or overloading. Preferably, the annular space is in communication with the holes, and the annular space is configured to receive and then to release and distribute the fluid via the holes in a substantially uniform manner such that even amounts of fluid are released in the distal and proximal holes. The inner balloon may have various configurations including being tapered relative to the outer balloon. The outer balloon may also be tapered accordingly. The device may also include raised portions disposed in the annular space and configured to define channels having various configurations. | 10-08-2009 |
20100036314 | BALLOON CATHETER AND METHOD FOR MAKING SAME - In at least one embodiment of the present invention a balloon catheter is provided. The balloon catheter comprises a shaft having a lumen formed therethrough. Connected to the shaft is an inflatable balloon. The inflatable balloon has a balloon wall defining a balloon interior surface and a balloon exterior surface that is opposite the interior surface. In fluid communication with the balloon wall is the lumen for inflating the balloon to define an inflated state and for collapsing the balloon to define a deflated state. The balloon wall is textured in the deflated state such that the balloon interior surface is spatially registered with the balloon exterior surface. The balloon in the inflated state is tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state. | 02-11-2010 |
20100063442 | MEDICAL BALLOON HAVING A RESISTANCE TO CIRCUMFERENTIAL TEARING AND METHOD OF PRODUCING THE BALLOON - A medical balloon having a resistance to circumferential tearing comprises a substantially cylindrical portion disposed between first and second tapered portions that have a decreasing cross-sectional area along a length thereof away from the cylindrical portion. The substantially cylindrical portion includes first and second end portions and a midsection disposed therebetween. The midsection includes a first region having a first resistance to tearing and a second region having a second lower resistance to tearing, where the second region extends about only a portion of the circumference of the cylindrical portion and does not extend beyond the midsection. | 03-11-2010 |

20110313355 | WEEPING BALLOON CATHETER - Balloon catheters, and methods of treatment therewith, are provided including an inflatable first balloon at least partially enclosed by an expandable second balloon that has holes. The annular space between the first balloon and the second balloon is configured to promote delivery of the fluid evenly through holes in the second balloon to avoid problems of underloading and/or overloading. Preferably, the annular space is in communication with the holes, and the annular space is configured to receive and then to release and distribute the fluid via the holes in a substantially uniform manner such that even amounts of fluid are released in the distal and proximal holes. The first balloon may have various configurations including being tapered relative to the second balloon. The second balloon may also be tapered accordingly. The device may also include raised portions disposed in the annular space and configured to define channels having various configurations. | 12-22-2011 |

20130079866 | STENT GEOMETRY - A stent structure is provided with an alternating arrangement of hoop cells and flex cells. Longitudinal struts extend through the hoop cells but do not extend through the flex cells. The flex struts in the flex cells are wider than the hoop struts in the hoop cells. | 03-28-2013 |
20130289697 | LONGITUDINALLY REINFORCED SHEATH - A sheath for deploying a medical device to a target site in the body of a patient. A tubular inner liner has a proximal portion, a distal portion, and an outer surface. An outer jacket has a proximal portion, a distal portion, and an inner surface. A reinforcing member is received within a length of the outer jacket. The outer jacket is positioned longitudinally around the inner liner and bonded to the outer surface of the liner. The reinforcing member, which may be a triaxial braid, or an encapsulated longitudinal reinforcing wire, extends along the outer jacket length and is configured for inhibiting elongation of the sheath upon deployment of the device. | 10-31-2013 |
