STEERABLE, CONFORMABLE, DRUG ELUTING BALLOON CATHETER

摘要

A steerable, conformable, drug eluting balloon catheter device may comprise a catheter stem with one or more balloon element(s), themselves comprised of one or more segment(s) arranged radially or axially along the length of the device, and may allow precise deployment of vascular interventional devices, including coring devices and/or placement of stents, and may also allow targeted, specific placement of selected diagnostic or therapeutic materials on the walls of a vascular structure during a cardiovascular intervention procedure.

主权项

1. A device, comprising:
a bendable central catheter stem; a plurality of balloon elements disposed radially around the bendable central catheter stem, each balloon element comprising a plurality of individually-inflatable balloon segments extending from near a distal tip of the bendable central catheter stem to a distance proximal to the distal tip, wherein each balloon segment of each balloon element disposed radially around the central catheter stem is selectably and individually inflatable to cause the central catheter stem to selectively bend and conform to a shape of a vascular wall.
