Abstract: The present patent consists of an engineered multimeric protein complex as antibody substitute composed of human proteins, with an m-fold symmetry, with each m-fold element containing a modified monomeric protein derived from a symmetric human multimeric protein complex fused to a module containing n fused, modified human beta solenoid proteins (mBSP), and that fused to a human derived pathogen binding domain (PBD), as well as a separate antibody substitute composed of P human PBD complexes. The invention may find application in prophylactic and therapeutic treatments for viral infections, especially for COVID19 by neutralizing the SARS-CoV-2 virus.

Abstract: Amyloid fibrils comprising pathogen binding proteins and methods of their use are provided.

Abstract: In an example, a bioresorbable implant for use in a nasal region includes one or more bioresorbable polymers, and a pharmaceutical composition coupled to the one or more bioresorbable polymers. A release rate of the pharmaceutical composition is related to a degradation rate of the one or more bioresorbable polymers.

Abstract: Systems, devices and methods for eluting an agent at a treatment site are disclosed. The devices include an expandable frame and at least one membrane. The membrane may carry an agent to elute at the treatment site. The membrane may allow blood flow at the treatment site during agent delivery.

Abstract: A catheter configured for delivering an agent to a patient's vessel wall is described. The catheter includes an inflatable balloon substantially covered by a expandable cage such that when the inflatable balloon is inflated the expandable cage substantially surrounds an outer surface of the inflated balloon. The inflatable balloon is configured to be deployed within a lumen against a lumen wall and separated from the lumen wall by the expandable cage in an expanded state, and is adapted to provide an agent delivery to a treatment site, and the expandable cage is further collapsible and is removable from said lumen.

Abstract: Embodiments of a method and apparatus to prevent reperfusion injury. In one embodiment, blood flow proximal to a lesion is occluded. An infusion catheter is advanced to a region distal to the lesion and an anti-reperfusion injury drug is delivered. The lesion may then be treated with a dilating device to reintroduce blood flow to the region distal to the lesion.

Abstract: A stent for implantation in a body lumen for protecting from rupture a fibrous cap in order to treat vulnerable plaque. One embodiment of the stent achieves staged expansion through stronger and weaker circumferential regions, and includes optional anchors positioned at the circumferential transition between the stronger and weaker regions. During the first stage expansion, the weaker region expands moving the anchors laterally apart. The anchors straddle the fibrous cap and embed into the vessel wall. The second stage expansion of the stent exerts gentler stresses by the weaker region against the fibrous cap while the stronger region exerts greater stresses on the remainder of the vessel wall to open the vessel.

Abstract: The present invention relates to the treatment of vascular lesions using low doses of an mTOR inhibitor together with a low dose of a glucocorticoid on an implantable medical device, wherein the treatment is particularly beneficial when the patient is a diabetic or is suffering from an abnormally long or diffuse lesion.

Abstract: Embodiments of the present invention include methods for the treatment, prevention, or amelioration of vascular disease and/or disorder in diabetic patients. The methods include implantation of a stent including a drug, and the use of a drug coated balloon. The DES may be a DES having a metal body and a coating including the drug, or a bioabsorbable stent with drug in the body of the stent, in a coating on the stent, or both in the body of the stent and in a coating on the stent.
