摘要： A method of treating cardiac arrhythmia, including guiding a distal end portion of a catheter, the distal end portion having a distal tip and accommodating at least one ablation electrode into a desired intracardiac region, for example, from the inferior vena cava into the right atrium of a human heart, and then from the right atrium into the right ventricle of the heart, pulling the catheter backwards, for example, towards the inferior vena cava, until the distal tip engages an edge of an intracardiac orifice, for example, the tricuspid annulus whereby the at least one electrode engages a target tissue, for example, the isthmus of tissue between the tricospid annulus and the inferior vena cava, deflecting the distal tip into a hook-shaped configuration, and activating the at least one electrode to produce a substantially continuous lesion on the target tissue. The method makes use of a catheter pre shaped at its distal end, steerable with pull wires in two different normal planes, having one electrode which slides along the distal tip of the catheter.

摘要： A device, and method for performing cardiac ablations includes a therapeutic instrument, for example, an ablation catheter (10), to which is mounted a flexible, and braided electrode (14). The electrode configuration is selected so that it has a desired surface area for proper heat convection properties. RF energy (26) is delivered to the electrode to heat, thereby ablate local heart tissue, with the electrode having good convection abilities to protect against coagulation, embolisms, and other undesirable effects of ablation procedures.

摘要： A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.

摘要： A closed-ended catheter assembly that includes an electrically conductive pathway is disclosed. The conductive pathway enables electrical ECG signals from a patient's heart to pass through the closed-ended tip of the indwelling catheter while still preventing unintended fluid flow. In one embodiment, a catheter assembly is disclosed and comprises an elongate catheter tube including a closed distal end. The catheter tube defines a lumen and includes a valve defined in the catheter tube to selectively enable fluids to pass therethrough. The catheter tube includes a conductive element that provides an electrically conductive pathway between the lumen and an exterior portion of the catheter. The conductive element includes an electrically conductive sleeve disposed within the lumen and is positioned proximate a hole defined in a catheter tube wall. The hole enables fluids in a vessel of the patient body in which the catheter tube is disposed to contact the sleeve.

摘要： An access port for subcutaneous implantation into a body of a patient is disclosed. The port is typically subcutaneously connected to a catheter, a distal portion of which is disposed within a vein or other vessel of the patient. The port is configured with enhanced fluid handling features to improve fluid flow therethrough while reducing the likelihood of clotting or occlusions in the attached catheter, thus improving system patency. In one embodiment, for instance, an implantable access port is disclosed and comprises a body defining a reservoir, a needle-penetrable septum covering an opening to the reservoir, a stem defining an outlet to the reservoir, and a deformable element included in the reservoir. The deformable element is operably connected to a main portion of the septum and deforms in response to displacement of the septum to counteract a change in volume within the reservoir and prevent blood ingress into the catheter.

摘要： An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to intravascular introduction of the catheter. The ultrasound probe includes user input controls for controlling use of the ultrasound probe in an ultrasound mode and use of the tip location sensor in a tip location mode. In another embodiment, ECG signal- based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart.
