Publication number: 20240130854Abstract: Implants with fillable reservoirs have been developed that are suitable for rhinoplasty, breast reconstruction, ear reconstruction, and replacement, reconstruction or repair of other soft tissues. The implants can be filled with graft material prior to implantation. The implants are preferably made from resorbable polymers, can be tailored to provide different geometries, mechanical properties and resorption rates in order to provide more consistent surgical outcomes. The implants preferably have an interconnected network of unit cells with microporous outer layers and optionally some or all of the unit cells having at least one macropore in their outer layers. The implants can be loaded by injection with microfat, collagen, DCF, cells, bioactive agents, and other augmentation materials, prior to implantation.Type: ApplicationFiled: December 13, 2023Publication date: April 25, 2024Applicant: Tepha, Inc.Inventors: Skander Limem, Fabio Felix, Said Rizk, David P. Martin, Simon F. Williams

Publication number: 20240082465Abstract: Compositions of P4HB with high purity have been developed. The compositions are prepared by washing P4HB biomass prior to solvent extraction, and precipitating P4HB from solution. The same solvent is preferably used to wash the P4HB biomass, and as a non-solvent to precipitate the polymer from a P4HB solvent solution. The highly pure P4HB compositions are suitable for preparing implants. The implants may be used for the repair of soft and hard tissues.Type: ApplicationFiled: September 13, 2023Publication date: March 14, 2024Applicant: Tepha, Inc.Inventors: David P. Martin, Simon F. Williams, Kai Guo

Publication number: 20160048644Abstract: An apparatus that includes an input portal for receiving data including pointers for identifying health care providers and performance data correlated to the pointers. A first analyzer analyzes the performance data to identify categories of related performance data. A compiler compiles the data into compiled data that includes a plurality of the pointers and categories of data associated with the pointers. A second analyzer analyzes the categories of data and scores the data within each category to produce an outcome score for each category of data, where each outcome score is associated with a pointer. An access portal provides access to the data to health care providers, and provides health care provider-selectable display criteria to the health care providers using the access portal, and records a display criteria selected by each health care provider.Type: ApplicationFiled: May 28, 2015Publication date: February 18, 2016Inventors: Nicholas G. Anderson, David F. Williams, John S. Pollack

Publication number: 20150154358Abstract: Medical records are created and modified based upon the needs of the user. In addition to selecting information needed by a user from a database, the present invention identifies and eliminates information from the medical records that is not needed or wanted. A computer database is created by receiving from healthcare providers a plurality of electronic encounter records. The computer further receives input data relating to the medical information that the customer wishes to include in the desired report. The input data may include items to be included in the report or items to be excluded from the report. The computer analyzes the patient encounter records in the database to identify and select a subset of patient encounter records based on the input data. The computer analyzes the subset of patient encounter records to identify and remove medical information to thereby create a sub-subset of medical information again based on the input data provided by the customer.Type: ApplicationFiled: April 15, 2014Publication date: June 4, 2015Inventors: Nicholas G. Anderson, John S. Pollack, David F. Williams

Publication number: 20140136237Abstract: Efficient computer distribution of healthcare information is achieved by computer aggregating the healthcare information directly from multiple sources, namely, computers of healthcare providers, including EHR vendors, and patients. Financial incentives to share information are provided to the sources. Healthcare information may de-identified by removing some specific information about the patient and the provider, and inserting generalized information about each. Healthcare providers and patients may prohibit use of their information, limit the content of their information, and control to whom their information is sold. Compensation and distribution of information among purchasers may be controlled to ensure fairness. The healthcare information may be analyzed, reordered and filtered to generate data or reports in response to a purchase request.Type: ApplicationFiled: November 12, 2013Publication date: May 15, 2014Inventors: Nicholas G. Anderson, John S. Pollack, David F. Williams

Publication number: 20040148024Abstract: The present invention provides a soft tissue implant comprising an outer shell including at least one layer of biostable impervious polyurethane, wherein the outer surface of the outer shell comprises undulations to encourage tissue adaptation to the implant whilst preventing tissue ingrowth and wherein the implant is gel free. The outer shell may comprise multiple concentric layers and a core of polymer fabricated as a closed cell foam.Type: ApplicationFiled: March 18, 2004Publication date: July 29, 2004Inventor: David F. Williams
