摘要： A steerable guide wire includes a core wire having a proximal end and a distal end. A braided filament is affixed to the distal end of the core wire. An outer coil surrounds at least a portion of the core wire and the braided filament. A proximal end of the braided filament is secured to a distal end of the coil. By locating the braided filament in the distal tip portion of the guide wire, a guide wire is provided that is highly flexible, has a high degree of tensile integrity, and is highly steerable, even in tortuous vasculature. Filter and balloon catheters having braided filaments at the distal end are also described.

摘要： A catheter for use in angioplasty includes a shaft formed from an elongated metallic tube and has an inflatable balloon at its distal end. A plastic tube connects a distal end of the metallic tube to a proximal end of the balloon. The metallic and plastic tubes thus define a lumen for providing inflation pressure to the balloon. A metallic core member is attached to the metallic tube and extends distally therefrom through the plastic tube and balloon. The distal end of the balloon is sealably secured to the core member. A tip body is connected to the core member distally of the balloon, with a short guide wire lumen being defined on the tip body. The guide wire lumen is adapted to slidably receive a guide wire which then extends along the catheter exteriorly of the balloon.

The present invention also describes several embodiments for an improved removal element (252). One embodiment of the removal element of the present invention comprised a plurality of braided wires having an abrasive disposed thereon. Another embodiment of a removal element is to provide a plurality of individual wires within each "braid" to increase the abrasive surface area of the removal element. In this "multi-ended" configuration, a plurality of wires are bundled together to form a single multi-ended strand (330). These single multi-ended strands are then braided together and an abrasive is disposed thereon to form the removal element (252). In another embodiment or the present invention is to provide a braid pattern wherein each single primary braid wire within the braid pattern is individually radially wrapped with a second "wrapping" wire (342). The "wrapping" wire (342), which may be coated with an abrasive (344), primarily performs the removal function.

The material removal element has a distal end and a proximal end. A drive shaft is operatively connected to the distal end of the expandable material removal element for rotating the removal element. A catheter surrounds a portion of the drive shaft. The catheter has a distal end for operatively variably contacting the proximal end of the material removal element such that the removal element is rotatable with respect to the catheter. The catheter is shiftable with respect to the drive shaft for moving the material removal element between the expanded position and the contracted position. A number of novel methods for removing vascular occlusion material are also provided. One such method comprises the steps of: providing a vascular occlusion material removal device having an expandable occlusion material removal element, wherein the removal element comprises a plurality of braided wires, further comprising an abrasive disposed on the wires; providing a drive shaft disposed in and shiftable with respect to the removal element; intravascularly positioning the removal element distally of the occlusion material; shifting the drive shaft with respect to the removal element to expand the element intravascularly; and moving the removal element proximally within the vascular lumen to remove occlusion material. The removal element can also be moved distally within the vascular lumen to engage the occlusion material. Also, removed occlusion material can be collected by a collection portion on the removal element.

摘要： An improved guide for a medical insertion device includes a core, a jacket of hydrophobic polymer surrounding the core, and a mixture of hydrophobic and hydrophilic polymer coated onto the jacket. The hydrophobic polymer of the coating is the same as or compatible with the hydrophobic polymer of the jacket, resulting in improved bonding between the jacket and coating. The hydrophilic polymer of the coating provides a slippery surface which facilitates insertion of the device into a vein or other organ. The hydrophilic polymer has reduced tendency to leach or dissolve away, because it is ensnared with the hydrophobic polymer of the coating.
