Patent number: 6575960Abstract: 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.Type: GrantFiled: December 18, 2000Date of Patent: June 10, 2003Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Neil M. Becker, Kenneth K. Armstrong, Duncan Clarke, William P. Colvan, Paul Haldeman, Charles R. Peterson, Albert A. Quinones, Gary Thompson, Bruce Wilson, Victor Wilson, LaShun D. Tarver

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.Type: GrantFiled: December 18, 2000Date of Patent: December 3, 2002Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Neil M.
