Abstract: The present invention provides a dual lumen catheter shaft having a first dual lumen section and a second dual lumen section with a transition section therebetween. The present invention further provides a method of forming a dual lumen catheter shaft.

Abstract: Apparatus is provided for sealing a vascular puncture by causing a reduction in the circumference of the puncture tract through delivery of a closure agent into tissue surrounding the puncture tract. A resultant inflammatory response and volumetric increase cause the tissue to swell into the puncture tract, thereby sealing it.

Abstract: An improved apparatus for delivering and deployment of an expandable stent with a protection sheath within a blood vessel is provided. The system comprises a fluid pressure device which is coupled with a retraction device for the protection sheath such that after retraction of the protection sheath the stent is automatically deployed by the fluid pressure device. The advantage of the invention is an easy and simple operation of the apparatus.

Abstract: The present invention relates to an endoprosthesis having a plurality of web rings coupled by connectors, which include two or more essentially parallel struts and a foot extension protruding from one of the struts. An endoprosthesis constructed according to the principles of the present invention provides an elevated degree of scaffolding to a body lumen while retaining an acceptable degree of flexibility.

Abstract: Apparatus is provided for sealing a puncture within a vessel or tissue to provide hemostasis, comprising a first disk coupled to either a second disk or a spring, and sealingly engaged to the vessel or tissue surrounding the puncture. At least the first disk is preferably configured to substantially conform to the profile of the vessel or tissue when deployed. In one embodiment, the disks may be released from engagement with the vessel or tissue to reposition the disks after deployment.

Abstract: A method for connecting a catheter balloon with a catheter shaft of a balloon catheter that improves the welding quality of a weld between the catheter balloon and the catheter shaft of the balloon catheter. Preferably, a welding energy absorbing device is arranged, preferably in the form of a coloured tubing, in the area of a fixation site after attaching a pre-fixation and then to irradiate this welding energy absorbing device with the radiation energy to carry out the welding. After the welding the pre-fixation and the welding energy absorbing device are removed.

Abstract: Implants and methods of making same are provided for treatment or prophylaxis of coronary or peripheral vascular constrictions or vascular occlusions, and particularly, stenoses or restenoses, that comprise FK506 in chemically covalently bound, non-covalently bound or physically immobilized form.
