Abstract:

A system for reducing the diameter of a stent comprises a stent contracting assembly and a fluid source. The assembly comprises a plurality of contracting members that define a diameter reduction chamber for receiving a stent. When the chamber is in a pre-reduction configuration the stent has a first diameter and when the chamber is in a reduced configuration the stent has a second diameter. The second diameter is less than the first diameter. The fluid source is in fluid communication with the chamber and is constructed and arranged to inject a fluid therein. The fluid forms a fluid bearing between the contracting members and the stent which prevents the contracting members from contacting the stent in the reduced diameter configuration.

Abstract:

Implantable medical endoprosthesis delivery systems and methods for making and using the same. An example implantable medical endoprosthesis delivery system may include an inner member having a first lumen disposed therein. An outer member may at least partially surround the inner member so that a second lumen is disposed between the inner and outer members. The second lumen may be configured so that an implantable medical endoprosthesis can be disposed therein. The delivery system may also include a hub including a fluid introduction port, a first fluid flow path in fluid communication with the fluid introduction port, and a second fluid flow path in fluid communication with the fluid introduction port.

Abstract:

A renal denervation apparatus includes a treatment element dimensioned for deployment on or within a renal artery of a patient. The treatment element comprises a predefined pattern arranged to complete at least one revolution of the treatment element. The apparatus includes a treatment source. The treatment source and treatment element are configured to cooperatively facilitate communication of an agent from the treatment source to the pattern arrangement of the treatment element. The treatment element is configured to deliver denervation therapy using the agent via the pattern arrangement to one or more regions of the renal artery adjacent the pattern arrangement, such that at least one complete revolution of the renal artery is subjected to the denervation therapy.
