Title: Sutures utilizing shape memory alloys
Inventor: PYKA WALTER R
IPC: A61B17/06
Filed: 1991-02-20
Granted: 2000-06-13
Abstract: A suture and a suturing method are set forth for suturing a wound in the tissue of a patient and defined by tissue edges. The suture comprises an alloy member having a first end portion, a second end portion, and a first undeformed shape. It is deformable into a second deformed shape. The member has the property of recovering from its second shape towards its first shape upon the second shape being subjected to specified conditions. The first shape is a suturing loop adapted to draw and hold the tissue edges defining the wound together.    The second shape is adapted to allow the member to be drawn through the tissue in position for the loop to form. The method comprises inserting such a member while it is in its second shape into position for it to assume its first suturing loop shape and subjecting it to conditions which cause it to recover towards its first shape.

Abstract: A method for producing a selectively surface hardened cast iron part includes the steps of (a) heating the part to a desired austempering temperature of between about 450°F and about 800°F until the entire cast iron part  possesses  the  desired  austempering temperature substantially uniformly throughout it; (b) heating only the surface of the cast iron part to an austenitizing temperature of between about 1500°F and about 1800°F by immersing the cast iron part in a molten lead or tin bath until a desired thickness of an austenite layer is formed on the surface of the cast iron part, without substantial heating of the interior of the cast iron part;  (c) quenching the surface-heated cast iron part in a non-liquid  quenching  bath  atmosphere, i.e.  a  gaseous atmosphere, maintained  at  the  desired  austempering temperature, for a time adequate to transform the surface austenite layer to an ausferritic structure; and (d) cooling the cast iron part before bainite is formed in the heat-treated surface layer.  In this manner, only the heat-treated surface layer of the cast iron part is hardened,  because  it  is  quenched  from  both  sides simultaneously from two sources: self-quenching by the interior of the part,  and external quenching by the austempering atmosphere.  Typical heating times in step (a) are between about 10 minutes and about 10 hours, and in step (b) are between about 3 seconds and about 10 minutes.   The quenching time in step (c) is typically between about 15 minutes and about 8 hours.   These temperatures  and  times  usually  yield  a  hardened ausferritic layer on the part having a thickness of between about on the order of 1/100 of a inch and about 1/4 of an inch.  Unlike hardened layers formed by flame hardening or induction heating, the layer that is formed is of a uniform thickness without regard to the shape of the part.  Moreover, again in contrast to such methods, at no time during the formation of the layer is the layer heated above the austentizing temperature. The disclosed method is particularly advantageous in that it eliminates the previously required quenching bath of oil or molten salt, yet provides a uniform hardened layer more quickly than prior methods, thereby providing a better surface hardened cast iron part at a lower capital and production cost.

Abstract: A device which  is  a combination of  a method and apparatus and a filter,  such as but not limited to,  a conventional  lag  filter  for  digitally  processing  and filtering signals used in industrial control applications.        The method and apparatus provides a factor which is used by the filter to process the digital signal at the input to the device.  The method determines if the change in the input signal is either due to noise or a valid signal change.          Information which gives a past analysis of the trend in direction of the signal at the input to the device is used in the method.   The trend information includes a factor representative of the past history of the trend.  The method uses the most  recent  trend  indicator  to determine to a reasonable degree of confidence if the signal currently at the input to the device is or is not characteristic of noise.  If the signal at the input is not believed to be characteristic of noise, then the method adjusts the trend indicator by a tracking credit.  The tracking credit is, in effect, a further degree of confidence that change in the input signal is not characteristic of noise.   The method minimizes the tradeoff between valid signal response time and noise rejection associated with the prior art filters.
