摘要： A venous valve is disclosed for implantation in and selectively restricting the outflow of blood from a penile vein to aid a user in achieving and/or maintaining an erection. The venous valve includes a self-expanding stent framework defining a blood flow lumen there through. The self-expanding stent framework is constructed to recoil from a radially compressed configuration in which the blood flow lumen is narrowed to restrict blood flow through the venous valve to a radially expanded configuration in which the blood flow lumen is fully open to permit unrestricted blood flow through the venous valve. A recoil delay component is attached to the self-expanding stent framework for slowing the recoil of the self-expanding stent framework to thereby provide an extended time period during which the blood flow lumen is narrowed and blood flow through the venous valve is restricted.

摘要： A catheter and guide wire exchange system including a catheter that has a guide wire lumen with a guide way extending along a length of the proximal shaft. A guide member is slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. A transition section joins the trilumen proximal shaft to a coaxial distal shaft.

摘要： A flexible, conformally fitted coil for imaging of the human shoulder and topologically similar specimens is in the form of a band of flexible conductive foil covered by a soft flexible insulating material. The geometry of the coil is such that it can pass under the arm and over the top of the shoulder, providing high sensitivity for magnetic resonance imaging (MRI) studies of the shoulder in MRI apparatus having either a vertical or horizontal axial magnetic field. The flexibility of the coil and the generality of its geometry makes it suitable for examination of patients in a wide variety of sizes. Radio Frequency (RF) Power is delivered to and/or received from the coil via a matching network. The matching network may include a transformer to reduce the necessary current delivered to the coil, or RF current may be injected directly into and extracted directly from the coil. In the case where a transformer is used, the secondary winding is incorporated into the coil in such a fashion as to make the flexible coil removable and replaceable without direct electrical contacts.
