摘要： Systems and methods for treating a patient with dyspnea are disclosed. A method in accordance with a particular embodiment includes identifying the patient as suffering from dyspnea, and, based at least in part on identifying the patient as suffering from dyspnea, implanting an electrical signal delivery element within the patient in signal communication with an afferent neural pathway of a carotid body chemoreceptor. The method can further include at least reducing dyspneic sensations in the patient by directing an electrical signal from the electrical signal delivery element to the neural pathway to at least partially block afferent signals from the chemoreceptor.

摘要： The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing a procedure on a mitral valve (728) of a heart includes inserting an implant (924) into a left ventricle and orienting the implant in the left ventricle substantially below the mitral valve. The implant (924) and tissue (970) around the mitral valve (728) are connected and tension is provided to the implant, in one embodiment, in order to substantially reduce an arc length associated with the mitral valve (728). In another embodiment, the implant (924) is inserted into the left ventricle through the aorta and the aortic valve.

摘要： Methods and devices for deploying an endoluminal implant in a curved vessel. The devices include steerable catheters having a control member that extends to the distal end and operates to bend the catheter. In other cases, the stent includes a longitudinal adjustment member attached near the leading edge of the stent and operates to shorten or lengthen the stent and thereby induce a curvature. The stent is carried in a distal region of the catheter that is advanced into a curved region of a vessel. The catheter is bent and/or the stent is curved using the longitudinal adjustment member, and the stent is deployed to achieve uniform wall contact with the endoluminal surface of the vessel at the lesser curvature.

摘要： Methods and apparatus are provided for selective surgical removal of tissue, e.g., for enlargement of diseased spinal structures, such as impinged lateral recesses and pathologically narrowed neural foramen. In one variation, tissue may be ablated, resected, removed, or otherwise remodeled by standard small endoscopic tools delivered into the epidural space through an epidural needle. Once the sharp tip of the needle is in the epidural space, it is converted to a blunt tipped instrument for further safe advancement. A specially designed epidural catheter that is used to cover the previously sharp needle tip may also contain a fiberoptic cable. Further embodiments of the current invention include a double barreled epidural needle or other means for placement of a working channel for the placement of tools within the epidural space, beside the epidural instrument. The current invention includes specific tools that enable safe tissue modification in the epidural space, including a barrier that separates the area where tissue modification will take place from adjacent vulnerable neural and vascular structures. In one variation, a tissue abrasion device is provided including a thin belt or ribbon with an abrasive cutting surface. The device may be placed through the neural foramina of the spine and around the anterior border of a facet joint. Once properly positioned, a medical practitioner may enlarge the lateral recess and neural foramina via frictional abrasion, i.e., by sliding the abrasive surface of the ribbon across impinging tissues. A nerve stimulator optionally may be provided to reduce a risk of inadvertent neural abrasion. Additionally, safe epidural placement of the working barrier and epidural tissue modification tools may be further improved with the use of electrical nerve stimulation capabilities within the invention that, when combined with neural stimulation monitors, provide neural localization capabilities to the surgeon. The device optionally may be placed within a protective sheath that exposes the abrasive surface of the ribbon only in the area where tissue removal is desired. Furthermore, an endoscope may be incorporated into the device in order to monitor safe tissue removal. Finally, tissue remodeling within the epidural space may be ensured through the placement of compression dressings against remodeled tissue surfaces, or through the placement of tissue retention straps, belts or cables that are wrapped around and pull under tension aspects of the impinging soft tissue and bone in the posterior spinal canal.

摘要： The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing annuloplasty includes accessing a left ventricle of a heart to provide a discrete plication element (905) to the left ventricle, and engaging the plication element to tissue near a mitral valve (916) of the heart. Engaging the plication element (905) includes causing the plication element to gather a portion of the tissue to create a plication. In one embodiment, accesing the left ventricle of the heart to provide the plication element (905) includes accessing the left ventricle of the heart using a catheter arrangement.
