摘要:
A surgical cutting instrument adapted for percutaneous insertion into a body cavity to facilitate a minimally invasive surgical procedure. The surgical cutting instrument includes a shaft having a proximal end, an open distal end, and an axial lumen therebetween. An inlet opening may be fluidly coupled to the lumen at a proximal end of the shaft, for connection to a vacuum source for creating a suction force sufficient to retain the distal end of the shaft adjacent to a surface of a body structure within the body cavity. A cutting element is disposed within the lumen of the shaft near the distal end of the shaft, and is operable to cut the body structure without removing any substantial portion of the body structure when the shaft is held adjacent to the surface of the body structure.

An intraluminal graft and method for inserting the same are provided including a biocompatible body, anchors attached to surface of the body, and an engine that includes an engine coil positioned within and attached to the body. The coil also is configured for attachment to an insertion device.
摘要:
Hand-held endoscopy assembly for use in performing a medical procedure comprising a hand-held endoscopy device having a bore extending therethrough. A surgical tool is removably mounted in the bore and is retained in a fixed longitudinal position within the device while permitting rotation of the tool in the device. A valve in the bore establishes a substantially fluid-tight seal between the bore and the tool.
摘要:
A clip applier tool comprising an elongate tubular member having a bore extending therethrough and having proximal and distal extremities. A push rod is slidably mounted in the bore and has proximal and distal extremities. An actuator is mounted in said bore in said tubular member. The actuator means is connected to the distal extremity of the push-pull rod. First and second clip applier jaw members are mounted in the bore in said tubular member and have proximal and distal extremities. A pivotal connection connects the proximal extremities of the jaw members to the distal extremity of the actuator.
摘要:
Devices and treatments for various joint conditions include a resilient elongate orthopedic device inserted into a joint space using a suture. The suture is passed through the joint space and used to pull the orthopedic device into the joint space. The suture may be using a percutaneously inserted needle or other type of needle-based delivery instrument. The resilient elongate orthopedic device may be restrained to a reduced profile that permits minimally invasive implantation, but assume an enlarged profile when positioned at an implantation site.
摘要:
A prosthesis is provided for treating aneurysms, occlusive disease of vessels and body organs, and arterio-venous fistulas, occurring in single and bifurcated lumens. The prosthesis comprises an expandable coiled sheet portion having a biocompatible graft, either a sheet or tube, affixed thereto along part or all of the circumference of the coiled sheet portion. The prosthesis has a small delivery profile, making it suitable for use in a variety of body vessels. Methods of making and deploying the prosthesis in single and bifurcated lumens are also provided.
摘要:
Methods and apparatuses for treatment of various joint conditions include a device inserted into a joint space. During delivery, the profile of the device is constrained in at least one dimension to minimize invasive impact on tissue and/or bone. The device may be restrained for implantation by a thread or a rigid elongate member. After insertion, the device may expand at the implantation site.
摘要:
Methods and apparatus are provided for removing emboli during an angioplasty, stenting or surgical procedure comprising a catheter having an occlusion element, an aspiration lumen, and a blood outlet port in communication with the lumen, a guide wire having a balloon, a venous return sheath with a blood inlet port, and tubing that couples the blood outlet port to the blood inlet port. Apparatus is also provided for occluding the external carotid artery to prevent reversal of flow into the internal carotid artery. The pressure differential between the artery and the vein provides reverse flow through the artery, thereby flushing emboli. A blood filter may optionally be included in-line with the tubing to filter emboli from blood reperfused into the patient.
摘要:
Devices and treatments for various joint conditions include a resilient elongate orthopedic device inserted into a joint space using a suture. The suture is passed through the joint space and used to pull the orthopedic device into the joint space. The suture may be using a percutaneously inserted needle or other type of needle-based delivery instrument. The resilient elongate orthopedic device may be restrained to a reduced profile that permits minimally invasive implantation, but assume an enlarged profile when positioned at an implantation site. To facilitate insertion of the orthopedic device through a minimally invasive or limited access procedure, a delivery system may be used to support and orient the orthopedic device during implantation. In some instances, the delivery system may also reduce the delivery profile of the device for insertion through a minimally invasive or limited access procedure.
摘要:
An emboli filtration apparatus is provided comprising a guide wire having a filter element captured thereon, so that the guide wire is free to rotate and translate while the filter element remains stationary. The apparatus allows for movement and rotation of the guide wire as devices are advanced over it to treat occlusive disease, substantially without dislodging the filter element. In a preferred embodiment, the guide wire comprises a proximal stop configured to reposition the filter element during a medical procedure without having to remove or insert additional interventional devices.
