A hands-free faucet control device includes a water valve assembly, a foot peddle assembly and a pull wire connected there between. A continuously-formed injection molded valve housing includes two cylindrically-shaped apertures disposed adjacent to one another where each has an inlet water port and an outlet water port. A valve is disposed in each of the apertures, where both valves are simultaneously movable between a closed position and an open position. A foot pedal assembly includes a foot peddle bracket and an attached foot pedal, where the foot pedal is movable between an up position and a down position. A pull wire is connected at a pull wire first end to the proximal end of the valve and connected at a pull wire second end to the foot pedal, wherein movement of the foot pedal to the down position by a user moves the valves to the open position.

A method of ablating a uterine fibroid using a particular trocar is disclosed. The trocar comprises a plurality of ablation stylets. The trocar is adjustable to assume a plurality of configurations, each of the configurations having the stylets extended to a different extent from the trocar. A region to he ablated is imaged, The size of the region to be ablated is noted. The size of the region to be ablated is compared to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the particular trocar. The region to be ablated is associated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions. A trocar is inserted into the uterine fibroid at a position, which more closely matches the position of the particular trocar with respect to the known ablation region. The stylets are deployed from the trocar to an extent corresponding to the configuration.

Ablation method

A method of ablating a uterine fibroid using a particular trocar is disclosed. The trocar comprises a plurality of ablation stylets mounted for movement from within the trocar to positions extending from the trocar. The trocar is adjustable to assume a plurality of configurations, each of the configurations having the stylets extended to a different extent from the trocar. A region to be ablated is imaged. The region may correspond to all or a portion of a uterine fibroid. The size of the region to be ablated is noted. The size of the region to be ablated is compared to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the particular trocar, and each of the known ablation regions being associated with a position of the trocar relative to the known ablation region. The region to be ablated is associated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions. A trocar of the design of the particular trocar is inserted into the uterine fibroid at a position, with respect to the region to be ablated, which more closely matches the position of the particular trocar with respect to the known ablation region. The stylets are deployed from the trocar to an extent corresponding to the configuration associated with the most nearly matching known ablation region.

A trocar point defined proximate the distal end of the cannula. A deflection surface positioned between the trocar point and the proximal end of the cannula, the deflection surface being configured and positioned to deflect, in response to axial movement of the stylets in a direction from the proximate end of the cannula to the distal end of the cannula, at least some of the stylets laterally with respect to the cannula axis in different directions along substantially straight paths, the paths defining an ablation volume.

An anchoring member comprises a support structure and at least one anchor secured to the anchoring member. An anchor deflection member supports the anchoring member for sliding longitudinal movement in directions which result in advancement and retraction of a point on the anchor. A deflection lip is positioned relatively inwardly with respect to the guide surface. The deflection lip is positioned to outwardly deflect the point of the anchor as the anchor is advanced from a position removed from the deflection lip toward the deflection lip into contact with the deflection lip and beyond the deflection lip.

RF ablation device with jam-preventing electrical coupling member

A filling device and method, particularly for two-component sealants such as fibrin sealants, which enables two fluids to be separately and directly filled to the reservoirs of a dual syringe fluid applicator from two storage containers, which can be standardized, sealed, sterilized bottles. The device has a connector which engages with the fluid applicator, is keyed to orient the applicator's fluid reservoirs in a predetermined manner and holds the containers in side-by-side alignment with the applicator. Two fluid conduits whose downward ends may be pointed to pierce seals on the bottles, extend between the applicator and the bottles and can each have a transverse reach to accommodate the girth of the bottles. The bottles may be tilted by the device to enable the conduits to draw maximal fluid from a lowermost point of the bottle. Tilting can be effected by a downward movement of the device supporting the applicator which movement can introduce the fluid conduits into the bottles. A shroud can enclose and seal the bottles and permit the apparatus complete with fluid applicator to be introduced into a sterile environment. Additionally embodiments for use with a single vial are also disclosed.

Direct dual filling device for sealing agents

A laparoscopic spray device for selectively applying a multiple component material dispensed from a multiple component material applicator to a surgical site in vivo is disclosed. The device comprises an interface member capable of engaging a multiple component applicator, a body having at least two lumens therein, and a detachable spray tip in fluid communication with the body. The detachable spray tip includes a mixing chamber having at least one flexible mixing member positioned therein which is capable of creating a turbulent flow within a mixing chamber. In addition, the at least one mixing member prevents a back flow of material from the mixing chamber to the at least two lumens. The present invention is particularly useful in remotely applying multiple component tissue adhesives to an internal incision.

The hood may include at least one engaging surface and at least one displacement recess. In addition, the container support device may include at least one biasing member capable of biasing the material container from an upright position to an upright tilted position, thereby enabling the withdrawal of substantially all the material from the material container.

A method and apparatus for reconstituting a multiple component material is disclosed. More particularly, the present invention discloses an apparatus utilizing an operator controllable pressurization device to generate a pressure differential between two receptacles attached to the device. The receptacles may contain individual components of a multiple component material, and may include liquid-liquid or liquid-solid compounds. The apparatus includes a material transfer lumen attachable to a first and second component receptacle. A pressurization lumen is connected to one of the component receptacles to facilitate material transfer. One embodiment of the present invention utilizes a negative pressure differential created in the second receptacle to facilitate transfer. In another embodiment, a positive pressure is created in the first receptacle to force material transfer between the two receptacles.
