Abstract: Ablation catheters and systems include flexible catheter tips with at least one positioning element and ports for delivery of an ablative agent to a target tissue. The positioning element is used to define a treatment zone and position the catheter proximate the target tissue for ablation. Ablative fluid is delivered to the target tissue at subtherapeutic, therapeutic, or supratherapeutic doses over different time periods, with rest periods between each dose, to cause effective ablation of the target tissue.

Abstract: Ablation systems and methods include an improved approach to generating heated vapor. The system includes a controller having a user interface and receives data indicative of a treatment time or desired energy level to be delivered during a treatment session, a pump in data communication with the controller, and a catheter having a bipolar electrode in fluid communication with the pump. The controller is configured to control a delivery of fluid and a generation of heated vapor based on the data indicative of the treatment time or desired level of energy to be delivered without modifying the flow rate of the fluid or the level of voltage and/or current of the electrical current based on data from sensors positioned in or on the catheter.

Abstract: Ablation systems and methods include an improved approach to generating heated vapor. The vapor ablation system preferably has a controller having a user interface that receives data indicative of a time of a treatment session, a pump in data communication with the controller, and a catheter having an electrode and is in fluid communication with the pump. The controller is configured to control the pump to provide a fluid to the lumen of the catheter, cause an electrical current to be delivered to the electrode in order to heat the fluid in the lumen and convert the fluid to a heated vapor, control a delivery of the fluid and a generation of the heated vapor based on the data indicative of the time and without modifying the flow rate of the fluid or the level of voltage and/or current of the electrical current based on data from sensors positioned in or on the catheter.

Abstract: A device for delivering an occlusive element includes an elongate sheath having a lumen therein. An elongate core member is disposed within the lumen and is formed from a proximal portion and distal portion connected via a joint. The distal portion of the elongate member includes a severable junction secured to the occlusive element. A marker coil is coaxially arranged around the distal portion of the elongate core member and is partially disposed inside the sheath lumen. A coil member is coaxially arranged around the distal portion of the elongate core member and coaxially arranged around at least a portion of the marker coil extending outside the lumen of the sheath. The coil member is secured at a distal end thereof to the distal portion of the elongate core member. The device resists axial compression while allowing for radial bending.

Abstract: An implant assembly comprises an elongated pusher member, and an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member. The implant assembly further comprises an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, and a return electrode carried by the distal end of the pusher member (e.g., a coil disposed about the pusher member) in proximity to, but electrically isolated from, the severable joint. The implant assembly further comprises a terminal carried by the proximal end of the pusher member in electrical communication with the severable joint.

Abstract: An apparatus for delivering bone cement into a vertebra includes a cannula and a mix and delivery device pivotally coupled to the cannula. The mix and deliver provides a single device in which a flowable compound may be mixed and the dispensed into the vertebrae through the cannula. The mix and delivery device includes a piston, slidably disposed within a barrel of the device, for advancing the bone cement through an outlet communicating with the cannula. An actuating device, which exerts a pressure, is connected to an inlet on the mix and delivery device (either directly or through a tube). The pressure created by the actuating device is used to advance the piston within the mix and delivery device.

Abstract: An apparatus for delivering bone cement into a vertebra, includes a cannula, a delivery device in communication with the cannula and a pressure delivery device in communication with the delivery device. The pressure delivery device provides an actuating force that acts either directly or through a medium to cause a flowable compound to be delivered from the delivery device to the cannula and into the vertebra. The pressure delivery device causes a pressurized compound to be delivered, the pressurized compound may be liquid or gaseous CO2 or other mediums.

Abstract: A vehicular frame assembly upon which a body portion and other components of a vehicle can be mounted is manufactured by initially casting a node that includes a body portion having a plurality of mounting portions. A first structural member is secured to each of the mounting portions of the node. Second structural members are secured to the first structural members to form a vehicular frame assembly upon which a body portion and other components of a vehicle can be mounted. If desired, a plurality of nodes is initially cast that each include a body portion having a plurality of mounting portions. A plurality of structural members is secured to the plurality of nodes to form the vehicular frame assembly.
