Patent number: 7749239Abstract: The present invention, the screw-device, is a mechanical device for anastomosing hollow tube-like structures in the human body, such as blood vessels, bowels and ureters. It is thus not restricted to (micro-) vessels. It can be used in every surgical operation dealing with anastomosis and bypass operations. It allows anastomosing end to side or side to side. The screw-device is very easy to apply onto the vessel wall. Screwing is a fast technique saving operating time and requiring only basic microsurgical skills. The manufacturing is easy. Another advantage is that the screw-device can be mounted onto the receptor vessel without first opening and/or occluding this vessel. Later on, the receptor vessel wall can be opened with laser or scalpel. It should be understood that the foregoing is illustrative and not limiting, and that modifications may be made by those skilled in the art, without departing from the scope of the invention.Type: GrantFiled: July 22, 2003Date of Patent: July 6, 2010Inventor: Erwin De Winter

Patent number: 7722664Abstract: A modular elongated stent having an overlap region where two modular components fit together, the overlap region being relatively stiff as compared to another more flexible region of the stent when the stent is in an assembled configuration, the stent further comprising a mimic region that has a stiffness essentially equivalent to the stiffness of the overlap region, to provide kink resistance. A stent having such a mimic region or otherwise stiff region and a flexible region may have a transition region between the stiff and flexible regions, also to provide kink resistance. A stent may have relatively stiff regions and relatively flexible regions positioned to align the flexible regions with curved regions of a body lumen when deployed within the body lumen. The stiffness of the stiff, flexible, and transition regions may be controlled by varying the cross-sectional area of the stent components and/or by varying the stent architecture.Type: GrantFiled: April 13, 2007Date of Patent: May 25, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: David J.

Patent number: 7691127Abstract: Drug eluting vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. The devices and methods rely on a combination of the body's own natural mechanism to achieve hemostasis with bio-chemical agents to accelerate the hemostatic process. One method includes the steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A bio-chemical sealing member disposed proximal the expansible member is then displaced so as to expose a bio-chemical region or release region of the device. At least one bio-chemical agent is thereafter released from the device and into the tissue tract to accelerate the occlusion process in the tract.Type: GrantFiled: December 13, 2005Date of Patent: April 6, 2010Assignee: Cardiva Medical, Inc.Inventor: Zia Yassinzadeh
