Patent number: 10280360Abstract: A well treatment microemulsion includes an oil external phase, an internal aqueous phase and a hydrophilic surfactant. The surfactant has a hydrophile lipophile balance of between 8-18. The oil external phase may include d-Limonene, xylenes, light mineral oil, or kerosene. The surfactant is configured to emulsify the water of the internal aqueous phase into the oil of the external (continuous) phase. The surfactant may include polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan tristearate, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monolaurate or mixtures therebetween. The use of hydrophilic surfactants to emulsify an internal aqueous phase within an oil external microemulsion produces unexpected and beneficial results.Type: GrantFiled: November 23, 2015Date of Patent: May 7, 2019Assignee: Flotek Chemistry, LLCInventors: Lakia M.

Patent number: 8333774Abstract: A suturing instrument having a dock at the end for receiving and securing a needle attached to a suture. The suturing instrument includes a cannulated handle attached to the proximal end of a cannulated shaft. The proximal end of a needle is removably received and securely received in the curved needle dock formed on the distal end of the shaft. The suture attached to the needle passes through the shaft and out the proximal end of the handle. Once the instrument is inserted into the body (usually through a cannula), the suture is retracted at the proximal end of the instrument handle, which draws the attached needle into the needle dock. The suture dock preferably has a compound curvature which prevents substantial rotation of the needle upon insertion.Type: GrantFiled: October 21, 2004Date of Patent: December 18, 2012Assignee: Arthrex, Inc.Inventor: David S.

Patent number: 8038652Abstract: Flexible button cannulas for arthroscopic surgery made from silicone, or a similar flexible material. Exemplary embodiments of the button cannula have large inner and outer flanges for improved stability when installed into the body. Exemplary embodiments of the button cannula include two fluid dams. A first dam is located within the cannula elongated portal between the inner and outer flanges and prevents fluid from squirting out of the body when instruments are being inserted through the cannula. A second dam is located at the outer, or top, flange (i.e., the flange that remains outside of the body) to prevent fluid from squirting when the cannula itself is being inserted within the body. Exemplary embodiments of the button cannula also include an outer, or top, flange that is thicker than the inner, or bottom, flange, to prevent the over insertion of the cannula into the body.Type: GrantFiled: March 2, 2009Date of Patent: October 18, 2011Assignee: Arthrex, Inc.Inventors: David S.
