Publication number: 20170135803Abstract: Provided is a stent that is placed in the bile duct to facilitate bile secretion into the duodenum. The stent includes an elastically deformable body, a film part, and an anti-inversion part. The body has a predetermined diameter and length and is formed by interlacing wires in the form of a tube. The film part surrounds to cover at least a portion of the body, extends a predetermined length from one end of the body, and is made of a flexible material. The anti-inversion part is connected to the one end of the body from which the film part extends and prevents the film part from being inverted and folded inwardly toward the body.Type: ApplicationFiled: July 9, 2014Publication date: May 18, 2017Applicant: S&G BIOTECH, INC.Inventors: Jong Ho Moon, Sung Kwon Kang

Publication number: 20110125254Abstract: The present invention relates to a drug releasing membrane for stent and a drug releasing stent for intraluminal expansion comprising the same. The drug releasing membrane according to the present invention has a two layer structure consisting of an inner layer M1 and an outer layer M2, the inner layer M is a thermosetting resin layer, and said outer layer M2 is a thermoplastic resin layer containing drug particles. In addition, the drug releasing stent for intraluminal expansion according to the present invention has a structure in which said drug releasing membrane M is inserted in a cylindrical stent body S woven with shape memory alloy wire. The present invention has excellent physical properties in spite of contact with bile during use, and is also excellent in drug therapeutic effect since drug is released only in one direction toward the skin.Type: ApplicationFiled: October 30, 2007Publication date: May 26, 2011Applicant: S & G BIOTECH, INC.Inventors: Sung-Gwon Kang, Se-Chul Lee, Seung-Hwan Jaegal, Woo-Sung Yang, Don-Haeng Lee

Publication number: 20100249901Abstract: The present invention relates to a cylindrical stent, which is a self-expanding type medical appliance for expanding the lumen of a blood vessel or esophagus that is stenosed, more specifically a cylindrical stent made of metal material forming a plurality of peak portions P and valley portions B and having a lengthwise axis. The cylindrical stent is characterized in that the end portions A of the peak portions forming both of the distal portions of the cylindrical stent are bent in the inward direction of the cylindrical stent. The present invention can effectively prevent the problem that a false blood vessel is formed as the vessel wall is exfoliated, broken or damaged due to contact between the distal portion of the cylindrical stent arid the vessel wall, and has an effect of effectively preventing the problem that inflammation occurs at the contact portion due to contact between the lumen wall of an esophagus, etc. and the distal portion of the cylindrical stent.Type: ApplicationFiled: February 15, 2008Publication date: September 30, 2010Applicant: S & G BIOTECH, INC.Inventor: Sung-Gwon Kang
