摘要： A balloon arterial cannula and methods for filtering blood. The devices generally include a mesh for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta, a structure adapted to open and close the mesh within the blood vessel, a means to actuate the structure, and a balloon occluder which typically includes a flexible material enclosing a chamber. The methods generally include the steps of introducing a mesh into a blood vessel to capture embolic material, adjusting the mesh, if necessary, during the course of filtration, inflating the balloon occluder to occlude the vessel upstream of the mesh, and thereafter deflating the balloon occluder and removing the mesh and the captured foreign matter from the blood vessel. Additionally, visualization techniques are used to ensure effective filtration.

摘要： The invention provides a nested tubing cannula which comprises outer and inner elongate tubular members, both having a proximal end, a distal end, and a lumen therebetween. The inner tubular member is sealed at its distal end and is nested substantially coaxially within the lumen of the outer tubular member, so that the gap between the inner and the outer tubular member defines a second lumen whereas the first lumen is the lumen of the inner tubular member. A tubular sleeve is disposed coaxially between the inner and outer tubular members. A balloon is mounted on a distal region of the outer tubular member and is in communication with the first lumen. The cannula further comprises a port proximal or distal the balloon occluder and is in communication with the second lumen. Methods for making the devices herein are disclosed.

摘要： An apparatus suitable for filtering emboli in an open surgical procedure. The apparatus comprises an elongated member having a distal region and a support hoop attached to the distal region. A blood permeable sac is affixed to the support hoop so that the support hoop forms a distally-facing mouth of the blood permeable sac. A guidewire is slideably attached to the elongated member. A delivery sheath is provided having a cavity for accepting the elongated member, support hoop and blood permeable sac, and a lumen extending through the cavity to permit the guidewire to pass therethrough. Methods of use are also described.

摘要： A filter system for temporary placement of a filter in an artery or vein is disclosed. The filter system includes a guidewire that is first positioned across a lesion within a vessel. The guidewire may include a distal stop. A slideable filter is then advanced along the guidewire using an advancing mechanism, typically an elongate member slideable over the guidewire and contacting the filter. A capture sheath may be disposed about the filter during advancement. Once the filter is positioned downstream of the lesion, the capture sheath is withdrawn, allowing the filter to expand. Further distal advancement of the filter is prohibited by the stop. After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.

摘要： A device for sensing the profile of a hollow body organ includes a hollow guidewire or probe carrying a sensor. The hollow probe includes a distal coiled end tube with a tip bent at an angle between about 10° to 90° relative to the probe longitudinal axis and having a torque response of no more than about 0.4 ozf in. The flexural rigidity of the distal end tube relative to the mid and proximal end tubes forming the probe is generally in the range of about 1:(4 to 4,400):(110 to 13,000), respectively. An actuator is detachably secured to the probe and includes one or several motors which allow the sensor to travel in a rotational and axial path through the body organ.

摘要： A guided filter system for temporary placement of a filter in an artery or vein is disclosed. The system includes a guidewire slideable through a wire guide included in a distal region of a support wire. The support wire has an expandable filter, which is operable between a collapsed or enlarged condition. A variety of endovascular devices, including angioplasty, atherectomy, and stent-deployment catheters, are insertable over the guidewire and/or the support wire. Methods of using the guided filter system to direct and exchange endovascular devices to a region of interest, and to entrap and remove embolic material from the vessel are also disclosed.
