    摘要: A support catheter that can puncture a heart septum with a guidewire without buckling and that can access difficult to reach arteries such as carotid or renal arteries from the aorta under difficult circumstances is provided. The support catheter comprises a catheter body having a proximal end, a distal end, and an interior wall surface defining a first lumen extending from the proximal end toward the distal end. A second lumen is disposed between the interior wall surface and an outer surface of the catheter body. A plurality of stiffening members is disposed around the second lumen, the plurality of stiffening members being engageable to selectively stiffen the catheter body. In another configuration, the catheter further comprises a second plurality of stiffening members disposed between the first lumen and the second lumen.

    摘要: A bifurcation stent delivery catheter includes a first branch balloon, a second branch balloon adjacent the first branch. A centering balloon is optionally disposed distal of the second branch balloon. The balloons are coupled by a coupling device to a main shaft of a catheter. The coupling device allows axial forces to be transmitted from the main shaft to the balloons while allowing the balloons to rotate axially relative to the main shaft with ease. The coupling device functions as an axial rotational joint. The coupling device can have a flexible tubular member that connects the balloons to the main shaft, the tubular member having a torsional flexibility greater than that of the main shaft. The coupling device can have a tubular wall having a cut extending circumferentially around the tubular wall and protective boot covering the cut. The coupling device can have a wound member that allows the axial rotation.

    摘要: Disclosed are catheter apparatus and methods for deploying a stent in a bifurcated vessel while minimizing flow problems in the branch vessel. In general, the catheter includes at least one non-compliant inflation structure for pushing a stent against a vessel wall in a main vessel and a compliant inflation structure for forming an opening in the stent across an opening in a branch vessel. Ideally, flow reduction caused by the stent is minimized due to the stent opening at the branch vessel. Additionally, other medical devices, such as a guide wire or a second stent, may be easily inserted through the opening in the stent into the branch vessel.
