摘要： A system for delivering a medical device, such as an angioplasty balloon, includes two catheter shafts. The distal portion of a first shaft includes a first balloon and is narrower than the proximal portion. A second catheter shaft includes a second balloon and is connected to a medial portion of the first shaft. The second shaft includes a guidewire passageway which is in communication with the passwageway of a third shaft that is removablly connected to the first shaft. The distal tips of the first and second balloons are connected together to allow the system to be advanced to an anatommical site using a single guidewire. A second guidewire may be used to separate the distal ends of the balloons and to position the balloons at vascular bifurcation. A stent can be crimped onto the balloons such that inflation of the balloons implants the stent within the bifurcation.

摘要： A balloon catheter for medical treatments easily manufacturable at low cost by a rather simple structure by providing a smaller diameter non-profile balloon catheter by eliminating the need for adhesion and welding of a balloon and eliminating extra profile at a connection part between the balloon and a shaft, wherein PTFE may be used for the shaft, and silicone may be used for the balloon. A inside hollow shaft (3) formed of a balloon material is inserted into an outside hollow shaft (2) formed of a shaft material, and the tip part of the inside hollow shaft (3) is projected from the tip end of the outside hollow shaft (2) to manufacture a double-tube catheter shaft (2). An expandable balloon (5) is formed of the projected portion of the inside hollow shaft (3), a cap (4) is fitted to the tip of the inside hollow shaft (3), and the PTFE is used for the outside hollow shaft (2), with the silicone used for the inside hollow shaft (3).

摘要： The present invention provides a method for exchanging catheters while containing emboli within a blood vessel such as a saphenous vein graft, coronary artery, carotid artery, or other similar vessels. A guidewire is inserted through the vasculature of a patient until it reaches a desired treatment site. A therapy catheter is then inserted over the guidewire until the distal end of the therapy catheter reaches the treatment site. The guidewire has a distally mounted balloon which is inflated to occlude the blood vessel. Then, the therapy catheter provides means for treating the vessel at the treatment site. After treatment, the therapy catheter is removed from the guidewire and exchanged with an aspiration catheter which rides over the guidewire until the distal end of the aspiration catheter reaches the treatment site. The aspiration catheter applies negative pressure to remove any emboli formed by the treatment procedure.

摘要： Disclosed herein is a catheter for use in an emboli containment system. In one embodiment, the catheter includes a flexible elongate member having self-expanding sealing means mounted on its distal extremity. This self-expanding sealing means can take any suitable form, such as a braided structure formed of a suitable shape memory material such as a nickel titanium alloy. In order to prevent abrasion of a vessel, it is desirable to cover the braided structure with a covering of a suitable material such as a polymer which extends over the braided structure and which moves with the braided structure as it expands and contracts.

摘要： A pressure-limiting or breakaway catheter includes a multi-lumen shaft having a distal end and a hollow balloon portion disposed at the distal end of the shaft. The balloon portion has a distal end and an interior. The shaft and/or the balloon portion has a balloon safety valve formed to open to the environment outside the shaft and/or the balloon portion when greater than a given bursting pressure exists within the shaft and/or the interior of the balloon portion. The safety valve can be formed to burst at a first breaking force less than a second breaking force required to burst the balloon portion and/or the shaft. Also provided is a breakaway catheter kit including a set of the breakaway catheters, each having the balloon safety valve with different safety valve breaking constants.
