20080295927 | THERMAL FORMING OF REFRACTORY ALLOY SURGICAL NEEDLES AND FIXTURE AND APPARATUS - A method of thermal forming of refractory alloy suture needles is disclosed. Needle blanks made from refractory alloys are used to form surgical needles, which are heated to a temperature above the ductile to brittle transition temperature but below the recrystallization temperature of the refractory alloy. The heated needle blanks are then mechanically formed into a surgical needle. A Fixture and an apparatus for forming refractory alloy surgical needles using this method are also disclosed. | 12-04-2008 |

Needle blanks made from refractory alloys are used to form surgical needles, which are heated to a temperature above the ductile to brittle transition temperature but below the recrystallization temperature of the refractory alloy. The heated needle blanks are then mechanically formed into a surgical needle. | 12-04-2008 |
20090157117 | PROCESS FOR TREATING METAL ALLOY SURGICAL NEEDLES TO IMPROVE BENDING STIFFNESS - A method of mechanically treating alloy metal surgical needles to improve bending strength is disclosed. The needles are curved and reverse-curved in this method to improve bending strength. | 06-18-2009 |
20100236935 | TUNGSTEN ALLOY SUTURE NEEDLES WITH SURFACE COLORATION - A medical device, particularly a suture needle, comprising a tungsten alloy and having a blue, yellow or black surface coloration. | 09-23-2010 |
20110060419 | MEDICAL DEVICES WITH GALVANIC PARTICULATES - Implantable medical devices having galvanic particulates are disclosed. The particulates may be coated onto at least part of a surface of the medical device. In addition, the galvanic particulates may be contained in the material used to manufacture the antimicrobial medical devices, or may be embedded into the surface of the medical devices. The present invention also provides novel coating methods and processing methods. The devices may have advantageous characteristics and effects including anti-microbial, anti-inflammatory, and tissue regeneration promoting. The medical devices may be used as bone implants. | 03-10-2011 |

Needle blanks made from refractory alloys are used to form surgical needles, which are heated to a temperature above the ductile to brittle transition temperature but below the recrystallization temperature of the refractory alloy. The heated needle blanks are then mechanically formed into a surgical needle. | 08-02-2012 |
20140171979 | Surgical Needle with Steps and Flats - A surgical needle for use in a circular needle applier comprises a distal leading end, a proximal trailing end, and an arced body between the leading and trailing ends. The body has a medial face and a lateral face. A first step on the body is adapted to be engaged by a circular needle applier. The first step is positioned distally from the leading end. A longitudinal flat extends proximally from the first step. The flat defines a generally D-shaped cross sectional shape in the body. A second step on the body is adapted to be engaged by a circular needle applier. The second step is positioned about 180 degrees from the first step. A length of suture is connected to the trailing end. | 06-19-2014 |
