Patent number: 9492279Abstract: A bioabsorbable plug implant, suitable for bone tissue regeneration, includes a first portion, and a second portion extending outwardly from the first portion, the first and second portions formed from expandable material. A method for bone tissue regeneration includes providing a bioabsorbable plug implant, wherein the implant has a first portion and a second portion extending outwardly from the first portion. The first and second portions are formed from expandable material. The second portion is inserted into a defect or gap of a bone. The first surface engages the outside contour of the defect or gap. The plug implant is allowed to contact body fluids, thereby expanding the size of the plug implant so that the plug fits into the defect or gap.Type: GrantFiled: March 24, 2014Date of Patent: November 15, 2016Assignee: OSTEOPORE INTERNATIONAL PTE LTD.Inventors: Swee Hin Teoh, Kim Cheng Tan, Dietmar Hutmacher, Thiam Chye Lim, Jan-Thorsten Schantz, Ning Chou

Patent number: 9067017Abstract: There is provided a flow system of a dialysis device including a dialysate conduit which is capable of being in fluid communication with the peritoneal cavity of a patient's body and of being in fluid communication with a flow path, the flow path allowing dialysate to flow from a patient's body to a sorbent capable of removing contaminants within the dialysate in an outflow mode and in an inflow mode returning the dialysate substantially free of contaminants to the patient's body. The device also includes a pump for moving the dialysate along the flow path in both the outflow mode and inflow mode and a plurality of valves disposed along the flow path. There is also provided a portable dialysis device.Type: GrantFiled: June 22, 2009Date of Patent: June 30, 2015Assignee: TEMASEK POLYTECHNICInventors: Kim Cheng Tan, Christian Gert Bluchel, Lay Leng Chew, Kee Kiat Chua, Lai Ching Helen Ho, Keng Hong Lee, Liutong Lin, Weng Cheong Roy Tang, Keng Mun Yue, Kim Jyh Wong, Cheng Lam Chua

Publication number: 20140358238Abstract: A bioabsorbable plug implant, suitable for bone tissue regeneration, comprising a first portion, and a second portion extending outwardly from the first portion, the first and second portions formed from expandable material. A method for bone tissue regeneration comprising the steps of: providing a bioabsorbable plug implant, wherein the implant comprises a first portion and a second portion extending outwardly from the first portion, the first and second portions formed from expandable material; inserting the second portion into a defect or gap of a bone, the first surface engaging the outside contour of the defect or gap; allowing the plug implant to contact body fluids, thereby expanding the size of the plug implant so that the plug fits into the defect or gap.Type: ApplicationFiled: March 24, 2014Publication date: December 4, 2014Applicant: OSTEOPORE INTERNATIONAL PTE LTD.Inventors: Swee Hin TEOH, Kim Cheng TAN, Dietmar HUTMACHER, Thiam Chye LIM, Jan-Thorsten SCHANTZ, Ning CHOU

Patent number: 8071007Abstract: The invention relates to the use of Fused Deposition Modeling to construct three-dimensional (3D) bioresorbable scaffolds from bioresorbable polymers such as polycaprolactone (PCL), or from composites of bioresorbable polymers and ceramics, such as polycaprolactone/hydroxyapatite (PCL/HA). Incorporation of a bioresorbable ceramic to produce a hybrid/composite material support provides the desired degradation and resorption kinetics. Such a composite material improves the biocompatibility and hard tissue integration and allows for increased initial flash spread of serum proteins. The basic resorption products of the composite also avoids the formation of an unfavorable environment for hard tissue cells due to a decreased pH. The scaffolds have applications in tissue engineering, e.g., in tissue engineering bone and cartilage.Type: GrantFiled: April 20, 2004Date of Patent: December 6, 2011Assignee: Osteopore International Pte. Ltd.Inventors: Swee Hin Teoh, Dietmar Werner Hutmacher, Kim Cheng Tan, Kock Fye Tam, Iwan Zein
