摘要:
Devices, tools and methods for occluding fluid flow between two walls of tissue in a patient. Two walls of tissue are compressed together with sufficient compressive force to prevent fluid flow between the two walls, while ensuring that the compressive force is not so great as to cause tissue necrosis. The devices, tools and methods may be carried out using minimally invasive surgical techniques, such as in reduced-access surgical sites. Devices, tools and methods are provided for occluding an atrial appendix.
摘要:
Methods and delivery devices for maximizing injectate dispersion in lesioned tissue using needle-based injection devices are herein disclosed. The delivery devices include injection devices with various needle arrays and/or modified needle tip configurations. The needle tip configurations can include linear, hooked or corkscrew tips and/or multiple circumferential openings.

摘要:
Apparatus and methods for performing endoscopic surgical procedures where only a minimal number of (or even one) openings are required to perform the procedures. Ablation procedures, including epicardial ablation procedures and apparatus for performing such procedures. Epicardial atrial ablation may be performed epicardially with access through only one side of a patient's chest required to perform all procedures.
摘要:
Implantable devices, methods of implantation and tools for performing the implantations. A device includes a volume occupying member having a working configuration such that, when the device is implanted into the abdominal cavity of the patient, the device performs at least one of: prevention of expansion of the stomach of the patient into a space occupied by the volume occupying member in the abdominal cavity; and compression of a portion of the stomach. A device is configured to have substantially neutral buoyancy or a slightly positive buoyancy when implanted in the abdominal cavity external of the stomach. An attachment member is connected to the volume occupying member, and at least a portion of the attachment member is configured to encourage tissue ingrowth from at least one internal abdominal structure when held in contact therewith.
摘要:
Methods, devices, tools and assemblies for treating a patient to effect weight loss. One method embodiment involves passing a device including an expandable member in a collapsed configuration and a buoyancy member through an opening in the skin of a patient and into the abdominal cavity of the patient, and anchoring at least a portion of the expandable member, relative to at least one structure in the abdominal cavity. Devices including at least one expandable member and at least one buoyancy member are provided.
摘要:
The present invention embodies an endovascular graft having various frame-to-main body component attachment mechanisms which provide a secured bond, reduced graft material wear, and reduced delivery profile.
摘要:
A method includes selecting a template from a plurality of different sizes of templates based on measurements of the abdominal cavity of a patient; orienting the template on the patient at a location overlying the abdominal cavity to select an appropriate size implant using fluoroscopic imaging; marking an incision location and an indicator of an angle of approach; and removing the template from the patient, wherein marks made by the marking remain on the patient. Methods apparatus, instruments and implants for treating a patient are provided.
