Publication number: 20150313685Abstract: During root canal procedures, pulp may be removed from a tooth without disturbing the dentin by directing pulses of a heated liquid onto the pulp at particular temperatures and pressures to liquefy or gellify the pulp. The liquefied or gellified material is then aspirated away using the methods and apparatuses described herein. In some embodiments the heated liquid also functions to kill bacteria that may be present within the tooth.Type: ApplicationFiled: July 10, 2015Publication date: November 5, 2015Inventors: Mark S. Andrew, Luis Alberto Davila

Patent number: 9089361Abstract: Target tissue may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the tissue to soften, liquefy, or gellify. The tissue that has been softened, liquefied, or gellified is then suctioned away.Type: GrantFiled: March 17, 2011Date of Patent: July 28, 2015Assignee: Andrew Technologies, LLCInventors: Mark S. Andrew, Philip P. Chan, Christopher P. Godek

Publication number: 20140188039Abstract: Visceral fat may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered in pulses, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the visceral fat to soften, liquefy, or gellify, without damaging the subject's internal organs that are in the vicinity of the visceral fat. The visceral fat that has been softened, liquefied, or gellified is then suctioned away.Type: ApplicationFiled: December 28, 2012Publication date: July 3, 2014Applicant: ANDREW TECHNOLOGIES LLCInventors: Mark S.

The fluid is delivered at a pressure and temperature that causes the tissue to soften, liquefy, or gellify. The tissue that has been softened, liquefied, or gellified is then suctioned away. The matter that was suctioned away is collected and gravity separated, and fat that is suitable for implantation in the subject is extracted from a selected layer (e.g., the top half) of the supernatant of the gravity-separated matter.Type: ApplicationFiled: September 19, 2012Publication date: October 3, 2013Applicant: Andrew Technologies LLCInventors: Mark S.

Patent number: 7011644Abstract: A method and apparatus are disclosed for liquefying target tissue within a body and aspirating the same while leaving non-target tissue intact. A biocompatible fluid is heated and contacted with target tissue so that the target tissue is melted while non-target tissue remains intact. As the target tissue is being melted it is also aspirated from the body.Type: GrantFiled: January 7, 2004Date of Patent: March 14, 2006Inventors: Mark S. Andrew, Mylina Andrew

Patent number: 6319222Abstract: A technique is described for liquefying, or gelifying, a hardened, cataractous lens nucleus and aspirating the same. Heat or heated solution is delivered to the lens nucleus in vivo so that the heat or heated solution is placed in contact with the hardened nucleus in order to heat and liquefy the same. The lens nucleus is irrigated simultaneously with a cooled solution to thereby limit to a very small area where the heat or heated solution is present in the eye. This allows the surgeon precise control over which intraocular anterior segment structures are exposed to the heat or heated solution. The liquefied lens nuclear material is then aspirated from the eye. The above allows the removal of a lens nucleus through a 1 to 2 mm corneal or limbal incision which is smaller than the smallest incision allowable with previously known small incision cataract techniques. The above benefits the patient as it allows small incision cataract removal to be done in a way that is non-traumatic to intraocular structures.Type: GrantFiled: April 20, 2000Date of Patent: November 20, 2001Inventors: Mark S. Andrew, Mylina Andrew

Patent number: 5619836Abstract: A sheetrock patch fastener that includes an integrally formed unit that is capable of supporting repair patches of various sizes and which is non-intrusive to the hidden surface of the sheetrock wall being repaired. The sheetrock patch fastener includes an upper portion, an intermediate portion, and a lower portion. The upper portion has an upper portion distal edge, an upper portion proximal edge, and a pair of upper portion distal edge corner teeth which extend downwardly from the upper portion at the ends of the upper portion distal edge. The intermediate portion extends downwardly from the upper portion and has an intermediate portion upper edge that is collinear with the upper portion proximal edge, and an intermediate portion lower edge.Type: GrantFiled: July 21, 1995Date of Patent: April 15, 1997Inventors: Duane A.
