Publication number: 20240138872Abstract: A surgical cutting tool includes an elongated shaft and a cutting head. The shaft defines a coupling portion terminating at a proximal end of the shaft, a stem portion, and a distal portion. The stem portion defines a central axis. The coupling portion optionally defines a deflection surface positioned oblique with respect to the central axis and connected with a first driven surface and a second driven surface. Upon insertion into a drive chuck, the deflection surface promotes self-alignment of the cutting tool and the drive chuck.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Inventors: Paul Cihak, Zachary Heiliger

Patent number: 9603603Abstract: A surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw includes a distal portion comprising a plurality of cutting teeth, a shank portion adjacent the distal portion, and a proximal portion adjacent the shank portion. The proximal portion may include a longitudinally extending slot having a proximal opening. The slot may be shaped to receive a portion of the surgical saw through the proximal opening. The proximal portion may have a plurality of deflectable fingers respectively separated from a plurality of main body portions by respective gaps. The plurality of deflectable fingers may extend adjacent the longitudinally extending slot, and may deflect into the gaps to increase and decrease a width of a portion of the slot.Type: GrantFiled: January 19, 2015Date of Patent: March 28, 2017Assignee: Medtronic PS Medical, Inc.Inventors: John Xinghai Wang, Hung Van Bach, Donna J.

Publication number: 20050106698Abstract: The present invention provides kPGE and derivative polypeptides which are capable of being produced by genetic recombination and used to produce EMCs. This invention further provides nucleic acid sequences encoding kPGE and derivative polypeptides which can be used to create recombinant host cells that express kPGE and derivative polypeptides. A further subject of the present of invention is a fusion polypeptide called polyHis-enterokinase which increases expression of esterases and lipases when fused to the N-terminal of the esterase or lipase. This invention also provides a method for treating animals with an esterase or lipase deficiency by administering rkPGE to the animal in a therapeutically effective amount.Type: ApplicationFiled: June 17, 2004Publication date: May 19, 2005Inventors: Paul Bolen, Paul Cihak, Lewis Scharpf
