Appl. No.:

11/032922

Inventors:

Joanne McLaughlin - Seal Beach CA, US
John Willis - Malibu CA, US
John Weir - Huntington NY, US
Madeleine Low - Los Angeles CA, US

International Classification:

C08K 9/06

US Classification:

523212000

Abstract:

A method is provided for pretreating metallic fillers adapted to be added into an organic polymer resin matrix adapted to cure into a material, wherein pretreating the fillers enhances the mechanical and electrical properties of the cured material. The method includes selecting an organofunctional silane based on compatibility of a functional organic with a selected polymer; determining an amount of silane required for treatment of the fillers by calculating the amount of silane required to provide monomolecular coverage of the particle surfaces of the filler based on a specific surface area measurement of the particle surfaces; uniformly dispersing the required amount of silane over the filler; allowing adequate time for the silane to react with particle surfaces of the filler; and mixing the treated filler into the polymer resin.

US Classification:

2271801, 2271761

Abstract:

A surgical instrument that includes an elongated shaft that defines defining a central axis. The elongated shaft may have a distal end portion that is configured to operably support a circular staple cartridge therein. A tissue acquisition shaft may be axially movable within the elongated shaft such that a distal end portion of the tissue acquisition shaft may be distally advanced beyond the distal end portion of the elongated shaft. At least one tissue acquisition member may be pivotally attached to the distal end portion of the tissue acquisition shaft such that at least one tissue acquisition member is selectively pivotable about a corresponding acquisition axis that is substantially parallel to the central axis from a retracted position to deployed positions upon application of a deployment motion thereto. Various embodiments include an annular cutting member that is supported by the distal end of the elongated shaft for selective axial travel relative thereto.

International Classification:

A61B 17/00

US Classification:

600 37

Abstract:

A device for protecting tissues and structures adjacent to a tubular organ during performance of a surgical procedure on a portion of the tubular organ. Various embodiments may comprise a member that may be deployed through a surgical instrument in a first configuration and expanded to a second configuration such that when in the second configuration, the protective member may extend substantially around an outer circumference of the portion of the tubular organ.

Abstract:

Surgical instruments are disclosed. Various non-limiting embodiments may include an elongated shaft that has a distal end portion that is configured to operably support a circular staple cartridge therein. A tissue acquisition shaft may be rotatably supported within said elongated shaft and have a distal portion that protrudes distally beyond the distal end portion of the elongated shaft. At least one tissue acquisition member may be pivotally attached to the distal end portion of the tissue acquisition shaft such that the tissue acquisition members are selectively pivotable from a retracted position to deployed positions upon application of a deployment motion thereto. A rotatable cutting member may be operably supported adjacent to the tissue acquisition member and being selectively rotatable about the central axis upon application of a cutting actuation motion thereto.

Abstract:

Surgical instruments and procedures for performing a circular anastomosis of a tubular organ. The surgical instruments may include selectively deployable tissue acquisition members configured to puncture through a portion of the tubular organ and position the portion of the organ adjacent to a fastener face of a staple cartridge supported in the instrument. At least one cutting member may be radially deployed and rotated to sever the positioned portion of organ from a distal portion of the organ. An anvil may be employed to draw another portion of the organ adjacent to the portion of organ positioned adjacent to the fastener face of the staple cartridge. The staples may then be deployed through the adjacent portions of organ and an annular knife may be advanced through the adjacent organ portions to complete the anastomosis.
