Publication number: 20230118531Abstract: The present invention generally relates to the use of small particles, such as micro particles or nanoparticles, to produce a therapeutic scar such as “trans-mural” scarring or other desired “deep tissue” scarring. In one preferred embodiment, these particles can be delivered to a target location by an implant. More specifically, these particles can be incorporated into the structure of implants or into the coatings on implants. In another preferred embodiment, these small particles can be delivered directly with a catheter by electrophoresis or hydraulic pressure.Type: ApplicationFiled: December 16, 2022Publication date: April 20, 2023Applicant: Syntach AGInventors: Zhihao Yang, Richard Cornelius, Paige Hastings, Bodo Quint, Gerd Siebold, Ib Erling Joergensen, Stevan Nielsen

Publication number: 20160256168Abstract: The disclosure relates to a medical implant for occluding an opening in a body and a method of producing such a medical implant. Disclosed is an improved occluder, which provides improved occlusion, improved sealing and improved endothelialization. A method is disclosed comprising braiding, knitting or weaving together strands to form a body mesh of strands forming a plurality of adjacent cells delimited by the strands. The method further comprises applying a first coating to said strands, and applying a second coating to at least part of an external surface of said medical implant, wherein said first coating provides a binding force to said second coating such that said second coating adheres to said strands.Type: ApplicationFiled: October 7, 2014Publication date: September 8, 2016Applicant: Occlutech Holding AGInventor: Stevan Nielsen

Patent number: 9017376Abstract: Apparatus is provided for sealing a vascular puncture by causing a reduction in the circumference of the puncture tract through delivery of a closure agent into tissue surrounding the puncture tract. A resultant inflammatory response and volumetric increase cause the tissue to swell into the puncture tract, thereby sealing it.Type: GrantFiled: June 30, 2011Date of Patent: April 28, 2015Assignee: Abbott Laboratories Vascular Enterprises, LimitedInventors: Stevan Nielsen, Bodo Quint, Randolf Von Oepen, Kenneth J. Michlitsch, Gerd Seibold, Tommy Conzelmann, Ib Erling Joergensen
