Publication number: 20210008217Abstract: The present invention generally relates to tumor homing statin derivatives (THSD) and their use for therapy, in particular cancer therapy. These THSD comprise three moieties: a statin moiety which comprises a dihydroxyheptanoic acid unit (DHHA) fixated by linkage into its open chain form, a heptamethine carbocyanine dye (HMCD) moiety, and a linker that conjugates the DHHA of the statin to the dye moiety. The linker is linked to the DHHA via an ester bond (ester-linked statin derivative or ELSD), or via an amide bond (amide-linked statin derivative or ALSD). Thus linked to the DHHA, the linker provides a relatively stable link either for essentially no hydrolysis/statin release after administration, or preferably for very slow hydrolysis and statin release, as is the case for the ELSD. Embodiments include methods to provide the desired THSD, in particular the ELSD, with the DHHA in its open chain form.Type: ApplicationFiled: July 10, 2020Publication date: January 14, 2021Applicant: Da Zen Theranostics, Inc.Inventors: Leland W.K.

Publication number: 20210008256Abstract: A system for adapting a tubular surgical device for grasping by a surgical instrument is provided that has a distal portion, an adaptor positioned proximally and configured to be disposed about or within a lumen of the tubular surgical device, which has an effective durometer to resist crushing by the surgical instrument. In some embodiments, the adaptor is configured with an external diameter greater than the internal diameter of the lumen of the tubular surgical device. In some embodiments, the adaptor is configured with an external diameter less than or equal to the internal diameter of the tubular surgical device.Type: ApplicationFiled: July 10, 2020Publication date: January 14, 2021Applicant: Vascular Technology, IncorporatedInventors: Ronald H. Russell, Stephen Martone, David Regan, Rachana S. Suchdev, Trevor Jacob Laughlin, Gary Douglas

Publication number: 20210008257Abstract: A surgical suction system. The surgical suction system includes a large bore Yankauer suction device having a distal tip with a first diameter, and a proximal end with exterior hose barbs and a second diameter. The second diameter is greater than the first diameter such that a channel extending through the large bore Yankauer suction device may have an increasing diameter from the distal tip to the proximal end. The surgical system also includes cannulated tubing having a distal end and a proximal end, the distal end configured to mate with the exterior hose barbs of the Yankauer suction device. The surgical system further includes an adapter having a distal end with exterior hose barbs and a proximal end. The exterior hose barbs configured to mate with the proximal end of the cannulated tubing. The proximal end of the adapter is configured to connect to a port to a canister, wall vacuum, or other biological material collection device.Type: ApplicationFiled: September 14, 2018Publication date: January 14, 2021Applicant: Conmed CorporationInventor: Jessica Snyder

Publication number: 20210008259Abstract: Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site.Type: ApplicationFiled: January 15, 2019Publication date: January 14, 2021Inventors: Justin Alexander LONG, Christopher Brian LOCKE
