Publication number: 20240181123Abstract: The present disclosure relates to a drug-eluting suture comprising an elongate strand formed of a polymer matrix. The suture includes an anti-inflammatory agent, such as tacrolimus, dispersed within the polymer matrix at a concentration ranging from 0.1% wt. to 5% wt., based on the total weight of the suture. The suture exhibits a porosity ranging from 1% to 20%. Under physiological conditions, the suture can demonstrate a mean anti-inflammatory agent release rate ranging from 0.1 ng/day to 100 ng/day for a period of at least 10 days.Type: ApplicationFiled: December 1, 2023Publication date: June 6, 2024Inventors: Azur AZAPAGIC, Jayant P AGARWAL, Himanshu J SANT, Bruce K GALE, Jill E SHEA

Publication number: 20230000772Abstract: An opioid independent surgical anesthetic composition includes an injectable dosage form of a hydrogel having a plurality of solid lipid matrix particles entrapped therein. The solid lipid matrix particles include a lipophilic local anesthetic drug and a lipid glyceride (e.g., saturated triglyceride or lipid blend of various lipid glycerides). Methods for creating a long-acting local anesthetic product can include creating a bulk solid of a lipid matrix product by heating a lipid solvent above its melting point, dissolving a lipophilic local anesthetic drug therein, reducing a temperature of the resultant drug-lipid solution to below the melting point of the lipid solvent, and heat annealing the lipid matrix to remove or reduce presence of any unstable polymorphs in the lipid matrix. The methods can further include crushing the bulk solid of the lipid matrix product to form solid lipid matrix particles and entrapping the solid lipid matrix particles within a hydrogel.Type: ApplicationFiled: March 1, 2022Publication date: January 5, 2023Inventors: Brett Davis, Andrew M.

Publication number: 20210378870Abstract: A wound dressing including a porous biosynthetic polymer film comprising a poly(lactide-co-caprolactone) (“PLC”) copolymer or other suitable polymer matrix, and a local analgesic loaded therein, to provide pain relief over an extended period of time (e.g., for 5-7 days), e.g., for healing of a partial thickness dermal injury. The PLC copolymer may have a particular lactide/caprolactone molar ratio (e.g., from 2:1 to 9:1) to ensure slow, sustained release of the bupivacaine or other analgesic. The dressing may provide a water vapor transmission rate from 1000 g/m2·day to 3000 g/m2·day to facilitate fast healing and regrowth of new epithelial tissue beneath the dressing. The dressing is configured to remain positioned over the dermal injury, providing wound protection for about 14 days, after which is simply debrides away, falls off, or is easily and painlessly removed, once new epithelial tissue regrows.Type: ApplicationFiled: August 23, 2021Publication date: December 9, 2021Inventors: Brett H.

Patent number: 9642623Abstract: Methods, devices, apparatus, assemblies, and kits for performing a vascular anastomosis are disclosed. A device for a vascular anastomosis includes tissue engaging portions that can move between at least two configurations. In some embodiments, the tissue engaging portions move without the aid of moving parts, while in other embodiments the tissue engaging portions extend from one or more movable wings. The tissue engaging portions may be separated by a first distance when in a pre-deployment configuration and by a second distance when in a deployed configuration. A method includes engaging a plurality of tissue engaging members of a coupling device against first end tissue. After selectively engaging the tissue engaging members and first end tissue, the first end tissue is stretched by at least moving the tissue engaging members. The stretched first end tissue is coupled to the second end tissue by mating the coupling device to a mating anastomosis device.Type: GrantFiled: April 15, 2011Date of Patent: May 9, 2017Assignee: The University of Utah Research FoundationInventors: Jayant P.
