A catheter shaft for a balloon catheter includes a centrally-located guidewire lumen. A body portion of the catheter shaft includes arc-shaped nodes that define a guidewire track within the guidewire lumen. Each node provides a single contact point for a guidewire within the guidewire lumen, thereby limiting frictional contact due to “rolling” friction, rather than “sliding” friction, between the catheter shaft and an inserted guidewire. The nodes include a crown region that includes the contact point. The crown region may be formed of a material having a lower coefficient of friction than the remaining portion of the catheter shaft. At least one node has an inflation lumen extending therethrough. The inflation lumen is in fluid communication with an interior of an inflatable balloon.
Catheter Having A Low-Friction Guidewire Lumen And Method Of Manufacture
A catheter shaft for a catheter includes a centrally-located guidewire lumen. A body portion of the catheter shaft includes arc-shaped nodes that define a guidewire track within the guidewire lumen. The nodes include a crown region that includes a single contact point for the guidewire and may be formed of a material having a lower coefficient of friction. At least one node has an inflation lumen extending therethrough. The catheter shaft has a cut in it extending radially from the guidewire lumen to an exterior surface of the catheter shaft. The balloon catheter has a guide member that opens the cut and tracks the guidewire in and out of the catheter shaft along a length of the catheter shaft which is cut.

Abstract:
A stent device including a stent body having a plurality of adjacent rows and one or more interconnections or interlocking rings between rows. The interconnections have first and second connecting portions with first ends permanently and immovably coupled to the rows and second ends interlocked with each other, such that the second ends of each portion can move independently of the other. The interconnections include ball and socket joints, hinge joints or universal joints. Interlocking rings have indentations for receiving the other ring, such that when interlocked, the rings will lay flat against a body lumen wall.
The present invention provides a method and system for loading drug onto a stent. The method comprises positioning at least one polymer coated stent on a mandrel, positioning a drug infused sheath onto the stent and diffusing drug from the sheath into the polymer coating of the stent. The system includes a drug coated mandrel and sheath positioned adjacent to and in contact with a polymer coated stent.

Abstract:
The invention provides a system and method for deploying a stent and infusing a therapeutic agent into tissue adjacent to the ends of the stent. The system comprises a catheter, an inflatable balloon, a stent, and a plurality of infusion elements. The catheter has an inflation lumen and at least one therapeutic agent delivery lumen. The balloon is disposed on the catheter and is in fluid communication with the inflation lumen. The stent is disposed on the balloon. The infusion elements are positioned adjacent to distal and proximal ends of the stent and are in fluid communication with at least one therapeutic agent delivery lumen. The infusion elements are inserted into a wall of a target region of a vessel responsive to inflation of the balloon. Further inflation of the balloon deploys the stent within the target region.
The present invention provides a method and system for loading drug onto a stent. The method comprises positioning at least one polymer coated stent on a mandrel, positioning a drug infused sheath onto the stent and diffusing drug from the sheath into the polymer coating of the stent. The system includes a drug coated mandrel and sheath positioned adjacent to and in contact with a polymer coated stent.

Abstract:
A drug eluting implantable device includes an exterior surface on the device and at least one recess formed in the exterior surface. The device further include at least one sidewall protruding from the exterior surface adjacent the at least one recess defining a channel with the recess into which the drug may be loaded, the sidewall including a perpendicular portion substantially perpendicular to the exterior surface and the sidewall further including a parallel portion extending from the perpendicular portion, the parallel portion extending from the perpendicular portion at an angle greater than about 90 degrees as measured with reference to the exterior surface.
Modular Stent Having Polymer Bridges At Modular Unit Contact Sites
A radially expandable modular stent for implantation within the body of a patient is disclosed. The modular stent includes a first stent module defining a first passageway, at least a second stent module defining at least a second passageway, and a least one polymer bridge in communication with the first stent module and the second stent module. The polymer bridge couples the first stent module to the second stent module such that the first passageway and the second passageway are in fluid communication.
