Definitions
- FIG. 23 is a view of an inflated anchoring balloon illustrating the forces exerted on the shaft of the transporter catheter.
- the shaft 101 comprises a plurality of sections with the plait-matrix layer or the helical-coil layer extending continuously from the proximal end 102 of the shaft to the distal end of the orienting balloon 107.
- the plait-matrix layer or the helical-coil layer extends continuously the entire length of the shaft 101 from the proximal end 102 to the distal end 103.
- the distal portion 202 of the shaft is more flexible than the outer catheter 224.
- the proximal portion 201 of the shaft is more rigid than the outer catheter 224.
- the plait matrix or the helical coil may be made of round wires, elliptical wires, flat wires or combination thereof. Wires of any other cross-sectional shapes may also be used.
- the wires may be made from various materials and may each be made of the same materials or materials with similar material properties, or different materials having different properties. As an example, such wires may be formed from stainless steel.
- the material of wires may be stiffer than the plastic materials forming the wall of the shaft.
- the flat wire is at least about 0.003" thick by about 0.007" wide.
- the wires may be made of Nitinol.
- the transporter catheter is pushed and/or torqued to advance the outer catheter substantially near a location of treatment in a patient’s vasculature.
- the second balloon may be deflated and upon further pushing and/or torqueing of the transporter catheter, the first balloon pulls the distal end of the outer catheter to the location of the treatment site or beyond the treatment site.
- the first balloon may be deflated, and the transporter catheter removed from inside the outer catheter and then a treatment system may be advanced inside the outer catheter to a location at the treatment site or beyond the treatment site.
- the first and the second balloon may be deflated, and the transporter catheter may be removed after the outer catheter is advanced to a desired location.
- the diameter of the orienting balloon 107 is smaller than the diameter of the second balloon 125.
- the length of the orienting balloon 107 is in the range of 10 mm to 20 mm.
- the length of the orienting balloon 107 is less than the length of the second balloon 125.
- the diameter of the orienting balloon 107 is in the range of 4-10 mm.
- the diameter of second balloon 125 is in the range of 20 mm - 30 mm.
- the valve is crimped on the second balloon 125 whereby the diameter of the crimped valve is less than 10 mm.
- the heart valve delivery system comprises an outer catheter 130 with a flexible tube 128 located at a distal portion of the outer catheter 130 (See Fig. 32), pull-wires 135 connected to the flexible tube 128, a transporter catheter 120 placed inside the outer catheter 130 with the anchoring balloon 129 positioned proximate to the flexible tube 128 of the outer catheter whereby when the anchoring balloon 129 is inflated, it presses on at least a portion of the flexible tube 128 of the outer catheter 130.
- the system further comprises a prosthetic heart valve disposed over the first balloon 127.
- the anchoring balloon 129 is formed on a flexible tube included in the transporter catheter 120.
- the clot treatment device 140 can be porous so blood flows therethrough.
- many embodiments of the clot treatment device 140 are made from a mesh or braided material.
- the material can be a super-elastic material such as Nitinol or an alternative material such as cobalt chrome alloy.
- the device can be made from a wire lattice, wire braid or stent.
- the clot treatment device 140 can self-expand from the undeployed state to the deployed state.
- the clot treatment device 140 can be a shape-memory material, such as Nitinol, and may be formed as a braid or a stent that is set to have the expanded configuration of the deployed state shown in FIG.
- inventive aspects may lie in fewer than all features of a single disclosed embodiment.
- an inventive aspect may include a combination of embodiments described herein or in a combination of fewer than all aspects described in a combination of embodiments.
