摘要:
The present invention relates to balloon catheters for treating a luminal system of a patient. Specifically, the invention relates to catheters having a flexible membrane positioned at a distal portion of the catheter, the flexible membrane retained in a substantially unexposed conformation prior to deployment. Preferably the flexible membrane is capable of delivering a therapeutic agent to a localized environment when deployed to an exposed conformation.

摘要:
A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member.
摘要:
A system for enlarging endothelium migration channels at a treatment site in a coronary vessel wall, to enable enhanced delivery of a therapeutic agent thereto. The system includes an enlarging agent, for enlarging endothelium migration channels at a treatment site in a coronary vessel wall. It also includes a delivery system, for delivering the enlarging agent to the treatment site, so that the enlarging agent will be delivered thereby to enlarge the endothelium migration channels at the treatment site, and for delivering the therapeutic agent to the delivery site. The therapeutic agent will thereby be delivered into the enlarged migration channels at the treatment site, to treat the treatment site with the therapeutic agent.
