摘要： An activation circuit for selectively providing an electrical current to one or more electroactive polymers (EAPs) in a medical device is disclosed. The activation circuit may include a sensor for sensing a measure related to a parameter of an elongated member and/or a balloon of the medical device. The electrical current may be provided to the one or more EAPs according to the sensed parameter of the elongated member and/or the balloon of the medical device. In some cases, the activation circuit may include a comparator for comparing the sensed measure to a threshold to determine when the electrical current is applied to the EAPs. The parameter may be a pressure, a fluid flow, a temperature, and/or other suitable parameter.

A balloon is located adjacent the distal end with a first port extending between the proximal end and the balloon providing for inflation an deflation of the balloon. A second port extends substantially between the proximal end and the distal end for drainage. A pair of ports separate from one another and from the first and second ports extend between the proximal end and the balloon. The pair of ports are each arranged in fluid communication with separate openings located between the balloon and the proximal end to provide separate fluid flow paths for the separate components of the two part biologic adhesive between the proximal end and the openings.

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.
