Abstract:
The invention provides a novel approach to controlled delivery of biomolecules (e.g., lipids and proteins) by employing novel amphiphilic polymers that are effective delivery vehicles. These unique amphiphilic polymers may be employed as controlled delivery vehicles or tissue engineering scaffolds wherein the delivery of lipophilic or amphiphilic bioactive molecules can be achieved. An amphiphilic biodegradable polymer platform is disclosed herein for the stable encapsulation and sustained release of biomolecules, such as SIP.
Abstract:
The present invention relates to compositions, methods and medical devices for the treatment of bone voids and bone defects. The methods of the invention comprise the step of applying to a bone void or bone defect site a composition comprising a matrix which provides local prolonged release of at least one antibiotic agent at the bone void site.
Abstract:
The present invention includes lipoic acid and derivatives thereof useful for removing microorganisms and/or biofilm-embedded microorganisms from the surface of a medical device or subject's body. The present invention further includes compositions and methods useful for coating medical devices. The present invention further includes compositions and methods useful for preventing or reducing the growth or proliferation of microorganisms and/or biofilm-embedded microorganisms on the surface of a medical device or subject's body.
Abstract:
The present invention relates to a gene delivery stent using a titanium oxide thin film coating, and to a method for fabricating the gene delivery stent. The gene delivery stent is loaded with medication having anti-inflammatory and antithrombotic functions, and delivers a gene for inhibiting the growth of vascular smooth muscle cells. Accordingly, late thrombosis or metal allergy can be reduced, and vascular restenosis in the stent region can be prevented, thereby increasing the treatment effects of the gene delivery stent when inserted in a blood vessel.
Abstract:
본발명은 티타늄 산화물 박막코팅을 이용한 유전자 전달 스텐트 및 그 제조방법에 관한 것으로,상기 본 발명에 따른 스텐트는 항염증 및 항혈전 작용이 있는 약물의 탑재와 동시에 혈관 평활근 세포의 증식을 억제할 수 있는 유전자의 전달을 동시에 가능하게 함으로써 후기 혈전증이나 금속 과민증을 감소시킬 수 있을 뿐만 아니라 스텐트 내 혈관 재협착을 방지할 수 있어 혈관 삽입용 스텐트의치료효과를 증대시킬 수 있는 장점이 있다.
Abstract:
The present invention provides compositions for extended release of one or more active ingredients, comprising a lipid-saturated matrix formed from a non-biodegradable polymer or a block- co-polymers comprising a non-biodegradable polymer and a biodegradable polymer. The present invention also provides methods of producing the matrix compositions and methods for using the matrix compositions to provide controlled release of an active ingredient in the body of a subject in need thereof.
Abstract:
Fatty acid-derived biomaterials, methods of making the biomaterials, and methods of using them as drug delivery carriers are described. The fatty acid-derived biomaterials can be utilized alone or in combination with a medical device for the release and local delivery of one or more therapeutic agents. Methods of forming and tailoring the properties of said biomaterials and methods of using said biomaterials for treating injury in a mammal are also provided.
Abstract:
The present invention relates to novel combinations of balloon catheters and active ingredient preparations adhering to the surface of the balloon membrane. The present invention further relates to coating methods for producing said balloon catheters, and to the use thereof for the treatment and prophylaxis of vascular diseases.
Abstract:
Disclosed herein are medical devices, such as stents, comprising a porous substrate, such as a porous ceramic. Also disclosed herein are methods for impregnating the porous substrate with a composition comprising at least one lipid and at least one pharmaceutically active agent, where the porous substrate is microporous and/or nanoporous.
