A device for treating disease along a main vessel and at least one branch vessel extending from the main vessel includes a branch member for deployment in the branch vessel, the branch member having a branch lumen; and a main body for deployment in the main vessel. The main body has a generally tubular wall extending generally longitudinally between opposite first and second ends. The wall has an internal surface defining a main lumen and an opposite outer surface. The wall has a recessed portion that is recessed relative to the outer surface of the wall and positioned between the first and second ends of the main body. The main body has an opening formed in the recessed portion of the wall for receiving the branch member therethrough such that the branch lumen is in fluid communication with the main lumen.

The present invention relates to methods of using medical cutting tools for treating aortic septal dissections.

Aortic dissection septal cutting tool

Method of using an aortic dissection septal cutting tool

The present invention relates to medical cutting tools for treating aortic septal dissections. The cutting tool is provided with a delivery catheter and has a remotely actuated cutting blade or cutting wire component. The cutting tool is provided with at least one displacement element. The displacement element assists in placement of the cutting tool at a desired location. The displacement element also assists in maintaining contact between the cutting blade and tissue being cut.

A stent-graft which is particularly useful for applications in biliary ducts. An expandable stent is provided with a covering of a material which is substantially impervious to body fluids and tissue ingrowth and has an increased resistance to bacterial attachment due to its lack of porosity and reduced surface texture. A preferred covering is porous PTFE film rendered substantially non-porous by a coating of a polymeric material such as FEP. The resulting stent has a thin wall for minimum pre-deployment diameter and for minimum interference with fluid flow through the device after implantation. It has good flexibility, allowing its use in curved ducts.
