International Classification:

A61M 3700

US Classification:

604 82, 604506, 604518, 606214

Abstract:

A filling device for connecting a dispensing instrument having multiple fluid reservoirs to multiple containers is disclosed. More particularly, the present invention discloses a connecting device capable of coupling the individual reservoirs of a dispensing instrument to multiple fluid containers. The apparatus includes a body, a collar extending from the body, a plurality of tubes in fluid communication with a plurality of inlet ports formed in the body, and a hood adapted to simultaneously receive a plurality of containers therein. The containers are positioned within the hood to allow the plurality of tubes to simultaneously and separately draw fluid from the fluid containers and transferring the material into the individual reservoirs of the dispensing instrument.

International Classification:

A61M 3700

US Classification:

604 82, 606214, 222129

Abstract:

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 applicators 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.

Assignee:

Baxter Healthcare Corporation - Irvine CA

International Classification:

A61M 500

US Classification:

604191

Abstract:

A sealant applicator suitable for dispensing a coagulable sealant, for example a two-component fibrin sealant mixed in the applicator, employs impulse clearing to remove residual coagulated or coagulating material from the dispensing pathway and mixing chamber, if present. Impulses may be generated by manual application of a clearing member such as a plunger which can enter into the dispensing pathway to engage, dislodge and discharge residuals or can generate a gas impulse to impact the residuals to similar effect. A clearing valve having a clearing port can be operated by movement of the clearing member to provide access to the dispensing pathway.

Abstract:

Multipurpose fluid applicators and applicator tips, particularly suitable for surgical purposes, are disclosed. The applicators and applicator tips are specifically designed for dispensing various combinations of sterile pressurized gas, suction, irrigation and sealant agents, including a mixed liquid sealant agent. Preferred embodiments employ a dual-acting valve selectively to control the flow of gas or suction which valve is capable of simultaneously varying flow from a source and the venting of that flow to atmosphere.

B67D005/52

US Classification:

604 82, 604191, 222137, 606214

Abstract:

A multi-component sealant applicator comprises a dual catheter for delivering sealant. Each catheter communicates with one of a pair of fluid sealant agent sources and comprises a mixing volume within the dual catheter for mixing multiple components of a multi-component sealant prior to discharge from a distal end of the catheter and a clearing system to clear undesired material from the mixing volume or the vicinity of the mixing volume, wherein one catheter is mounted for longitudinal movement within the other and the inner catheter is usable as a plunger to remove clogs. The catheter may comprise a reciprocal drive mechanism proximally coupled with the dual catheter to move one catheter longitudinally with respect to the other. The drive mechanism may comprise a ratchet and pawl.

Abstract:

An apparatus for cooling a skin surface includes a support structure coupled to an electromagnetic energy delivery device. The electromagnetic energy delivery device is configured to be coupled to an electromagnetic energy source. A cooling member is coupled to the electromagnetic energy delivery device and is configured to create a reverse thermal gradient through a skin surface. A memory is coupled to the electromagnetic energy delivery device and is positioned at the support structure or the electromagnetic energy delivery device. The memory is configured to store information to facilitate operation of at least one of the cooling member, and the electromagnetic energy source. Resources are coupled to the cooling member to permit different levels of cooling at different times of treatment.
