Publication number: 20120116438Abstract: Disrupting tissue and devices and systems for disrupting tissue. The disclosure describes ways to deliver moieties to a target tissue, where the target tissue in general is not at the point of introduction, in such a way that minimal damage is produced in the tissue at the point of introduction. In some embodiments this is accomplished by jetting fluid at high velocity into the target tissue. The disclosure further describes novel agents deliverable in such systems for use in remodeling tissues. Some of these agents comprise a liquid while others do not. Additionally, although not specifically described in detail much of the disclosure may additionally be used in the delivery of therapeutic drugs.Type: ApplicationFiled: January 17, 2012Publication date: May 10, 2012Inventors: Amr SALAHIEH, Alan SCHAER, Jeff KROLIK, John SPIRIDIGLIOZZI, Suresh PAI, Tom SAUL

Publication number: 20120004717Abstract: Apparatus and methods are provided for delivering a stent into an ostium. The apparatus includes a catheter including a proximal end, a distal end, and proximal and distal balloons disposed adjacent one another on the distal end. The balloons are expandable independently of one another, and a stent is provided surrounding the balloons. During use, the distal end of the catheter is introduced into a main lumen, and the proximal balloon is inflated to flare a proximal portion of the stent. The distal end is then advanced into the ostium until the flared proximal portion contacts a wall of the main lumen surrounding the ostium. The distal balloon is inflated to expand a distal portion of the stent, e.g., to dilate a lesion within the branch and/or ostium. Thereafter, the balloons are collapsed, and the apparatus is withdrawn, leaving the stent within the ostium.Type: ApplicationFiled: January 3, 2011Publication date: January 5, 2012Applicant: INCEPT LLCInventors: Arashmidos Sanati, Fred Khosravi, Jeff Krolik, Elliot Kim
