B21G 7/02
A61B 17/064

US Classification:

2271751, 606219, 59 77

Abstract:

An apparatus comprises a surgical instrument having a proximal end and a distal end. The proximal end may comprise a handle. The distal end may comprise a cutter and a stapler. The apparatus may further comprise a staple for use with the stapler. The staple may comprise an inner channel extending along at least a portion of the length of the staple. The apparatus may further comprise an agent contained in the inner channel, which may be used to coagulate a surgical site where surgical instrument is used. The agent may facilitate coagulation of the fluids at a surgical site once the staples are anchored to the surgical site.

International Classification:

A61B 17/068

US Classification:

2271761

Abstract:

An apparatus for endosurgical use includes an instrument having an end effector and a staple cartridge insertable into the end effector. The staple cartridge includes staples, staple apertures, a resistive member, and a medical fluid. When coupled to a power source, the medical fluid is vaporized by the resistive member and expelled out the staple apertures onto the stapled tissue. The power source may be contained within the instrument. In one configuration, a resistive strip with strip contacts may electrically couple to a conductor in the end effector. The medical fluid may also be divided into a plurality of sealant pads corresponding to the staple apertures, and the medical fluid may be a depolymerizable cyanoacrylate, a sprayable thermoplastic urethane, or any vaporizable medicament or pharmaceutical. The staple drivers may include one or more apertures to permit the medical fluid to pass through or around the staple drivers.

International Classification:

A61K 9/50
A61K 31/445

Abstract:

A sustained release pharmaceutical formulation for pain management comprises an active ingredient, and a water-miscible and hygroscopic network-forming material, the active ingredient being dispersed within the water-miscible and hygroscopic network-forming material. The pharmaceutical may comprise a hydrophobic component, wherein the active ingredient dispersed within the water-miscible and hygroscopic network-forming material are together dispersed in hydrophobic component. Optionally, the pharmaceutical formulation may be combined with a reinforcing member for providing a system for sustained release of the pharmaceutical formulation for pain management.
