摘要： The medical device includes a secondary wire guide and an advancement device. The advancement device has a tubular portion with a distal opening and a proximal opening. An edge region of the tubular portion forms the distal opening. A primary wire guide extends through the tubular portion. The secondary wire guide also extends into the tubular portion and has a distal portion configured to engage the edge region of the tubular portion. Accordingly, the secondary wire guide is advanced as the advancement device is translated into the blood vessel.

摘要： A method for embolic protection during treatment of a stenotic lesion in a body vessel is provided. The method comprises disposing an embolic protection device in an undeployed state in the body vessel. The device comprises a basket with a set of struts extending from a distal end to a proximal end of the basket, the struts being arranged to define an opening at the distal end, the basket having an expanded state and a collapsed state. A core wire with a distal end and a proximal end is able to reciprocate through the opening at the distal end of the basket. A filter bag is attached only at the distal end of the core wire, the filter bag being located distally to the distal end of the basket when in the collapsed state. The method further comprises moving the core wire relative to the basket to expand the basket and the filter bag in a deployed state downstream from the stenotic lesion to capture emboli during treatment of the stenotic lesion.

摘要： An embolic protection device includes a basket defined by a section of a set of wires arranged as a plurality of struts. These struts are coupled together at the distal end of the basket in a manner to define an opening at the distal end through which a core wire can reciprocate. Another section of the wires spirals around the core wire to define a hollow channel in which the core wire can reciprocate. A filter bag is attached to the distal end of the core wire such that pulling a proximal end of the core wire relative to the spiraled section engages the filter bag with the distal end of the basket to expand the basket and filter bag for capturing clots, and pushing the core wire disengages the filter bag from the distal end of the basket to collapse the basket and filter bag.

摘要： Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned.

摘要： A method of forming an introducer sheath having a crease-free tapered distal tip portion. A mandrel is provided having an outer configuration comprising an elongated body and a tapered distal tip portion. A generally tubular inner liner comprising heat shrinkable PTFE, is positioned over the mandrel. The inner liner is heat shrunk to the outer configuration of the mandrel, in a manner that avoids the formation of creases along the inner diameter of the liner. A reinforcing member is positioned over a length of the inner liner, and an outer jacket is positioned over the reinforcing member and the inner liner. The liner, reinforcing member, and outer jacket are heated in a heat shrink enclosure, whereby the outer jacket melts and bonds to an outer surface of the inner liner.
