Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures are disclosed. An access sheath is provided with at least one lumen, and a lens attached thereto. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic.
摘要:
A system for applying a fiber matrix on a tubular member is provided. A mandrel, configured for atraumatic placement within the tubular member, is included. Methods for atraumatic placement of a mandrel into a tubular member are also provided.
摘要:
Devices, systems and methods for dynamically stabilizing the spine are provided. The devices include an expandable spacer having an undeployed configuration and a deployed configuration. The spacer has axial and radial dimensions for positioning between the spinous processes of adjacent vertebrae. The systems include one or more spacers and a mechanical actuation device for delivering and deploying the spacer. The methods involve the implantation of one or more spacers within the interspinous space.
摘要:
Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Additional embodiments include a system that includes an interface unit for delivering one or more forms of energy to the ablation catheter.
摘要:
Devices, systems and methods are disclosed for the ablation of tissue and treatment of cardiac arrhythmia. An ablation system includes an ablation catheter that has an array of ablation elements and a location element, an esophageal probe also including a location element, and an interface unit that provides energy to the ablation catheter. The distance between the location elements, determined by calculating means of the system, can be used by the system to set or modify one or more system parameters.
摘要:
A system of catheter devices and methods for forming channels or passageways between a luminal anatomical structure (e.g., a blood vessel) and a target location (e.g., another blood vessel, an organ, a mass of tissue, etc.) for the purpose of rerouting blood flow or for delivering a substance or instrument, etc. to the target location.
摘要:
Devices, systems and methods are disclosed for the formation of an arteriovenous fistula in the limb of the patient. Embodiments include an apparatus for the creation, modification and maintenance of a fistula, including the modification of an existing dialysis fistula; and a method of supplying oxygenated blood to the venous circulation of a patient. A kit of anastomotic implants is described which supports a broad base of patient anatomies and fistula locations. The devices, systems and methods can be used to treat patients with one or more numerous ailments including chronic obstructive pulmonary disease, congestive heart failure, hypertension, hypotension, respiratory failure, pulmonary arterial hypertension, lung fibrosis and adult respiratory distress syndrome.
摘要:
A shunt rivet for implantation in the aorta and inferior vena cava to treat chronic obstructive pulmonary disease, and a method of treating chronic obstructive pulmonary disease.
摘要:
Methods, systems, devices and tools for placing bone stabilization components in a patient are provided. The systems and devices have a reduced number of discrete components that allow placement through small incisions and tubes. More particularly, the present invention is directed to screws for use in systems and methods of treating the spine, which eliminate pain and enable spinal motion, which effectively mimics that of a normally functioning spine. Methods are also provided for installation of the screw and other subject systems.
