摘要:
The present invention provides for therapeutic treatment methods, devices, and systems for the partial or complete closure or occlusion of a patent foramen ovale (“PFO”). In particular, various methods, devices, and systems for joining or welding tissues, in order to therapeutically close a PFO are described. In yet another aspect of the invention, various methods, devices, and systems for the penetration of the interatrial septum enabling left atrial access are also provided.

摘要:
A medical device is provided having a needle or a catheter, insertable into a living body, which defines a plurality of holes in fluid communication with a central lumen. The holes may be of various patterns located and angled to create a desired injectate cloud pattern when an injectate is forced through the central lumen and through the plurality of holes. One embodiment provides various designs including a moveable sheath or stylet used to selectively occlude one or more of the holes while in use, thereby providing an operating physician a way to manipulate the cloud pattern anytime during the introduction of the injectate. A reducer may be used in conjunction with these needles which provides an increased degree of control when injecting very small quantities of fluid.

The present invention provides an aortic valvuloplasty catheter which, in one preferred embodiment, has a tapered distal balloon segment that anchors within the left ventricle outflow track of the patient's heart and a rounded proximal segment which conforms to the aortic sinuses forcing the valve leaflets open. In addition, this embodiment of the valvuloplasty catheter includes a fiber-based balloon membrane, a distal pigtail end hole catheter tip, and a catheter sheath.

The present invention includes a prosthesis device composed of a plurality of filaments engaged together to self expand against the inner surface of a vessel. In this respect a pocket is created between the prosthesis and the vessel walls which prevent plaque and other debris from escaping downstream to potentially cause complications.
摘要:
An apparatus and method of use are disclosed for treating, preventing and terminating arrhythmias. In particular, the apparatus is implantable within or on various tissues and structures and is used to prevent or block conduction of aberrant impulses. A variety of methods of the present invention may be used to attack arrhythmias by short-circuiting impulses, inducing fibrosis, ablating tissue or inducing inflammation. In addition, the device and methods may also be used to treat aneurysms. The device may also be used to treat hypertension, and to function as a blood pressure regulator.
摘要:
The method calls for the periodic electrical stimulation of the heart muscle to alter the ejection profile of the heart thus reducing the observed blood pressure of the patient. The therapy may be invoked by an implantable blood pressure sensor associated with a pacemaker like device.
