An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.

Catheter assembly and method for treating bifurcations

A bleed back control assembly for controlling blood loss during catheterization procedures includes a side arm body having a proximal end engaging and retaining a cap assembly and a seal assembly. The seal assembly includes a single elastomeric bleed back seal. The bleed back seal has an aperture and is normally closed. The bleed back seal self-sizes to devices introduced through the aperture. The cap assembly includes a funnel cap having a dilator. Depressing the funnel cap causes the dilator to open the aperture in the bleed back seal. A spring, wound around the dilator, biases the funnel cap to its original position. The side arm body includes a secondary branch having a lumen, and a finger rest on the exterior of the secondary branch.

Bleed back control assembly

A bleed back control assembly and method-for controlling blood loss during catheterization procedures includes a side arm body connected at the proximal end to a seal body. The side arm body comprises one or more branches, each having a lumen, and a finger rest on the exterior of at least one branch. The seal body comprises a cap assembly and a seal assembly. The seal assembly comprises a clamp seal and a bleed back seal, both made of elastomer and held by a seal holder. The cap assembly comprises a threaded cap and a funnel cap. The threaded cap is connected to the seal holder. Rotation of the threaded cap causes the clamp seal to open or close. The funnel cap comprises a dilator, and pressing the funnel cap causes the dilator to open an aperture in the bleed back control seal.

A spring, wound around the dilator, returns the funnel cap to its original position, thus closing the bleed back seal. The bleed back seal self-sizes to devices introduced through its aperture. Dilating the bleed back control seal also allows purging of gases or fluids. The clamp seal can clamp a device introduced transluminally to maintain device position, and the clamp seal may also be closed to allow high pressure injections.
