1 US20090187254A1 07/23/2009 BOSTON SCIENTIFIC SCIMED, INC. UROLOGICAL MEDICAL DEVICES FOR RELEASE OF UROLOGICALLY BENEFICIAL AGENTS In previous attempts to develope a uerteral stent, encrustation was the problem associated with the stent. Along with this pain and discomfort by stent implantaion was there. This invention provides a ueteral stent which release one or more urologically beneficial agents in effective amounts to reduce the problem of encrustation and pain related to stent.
2 US20090171465A1 07/02/2009 Boston Scientific Scimed, Inc. Polymeric Regions For Implantable Or Insertable Medical Devices In previous attempts to develope a uerteral stent, encrustation was the problem associated with the stent. Along with this pain and discomfort by stent implantaion was there. This invention provides a ureteral stent with a coating of a material(EVA) that reduces the discomfort caused by the stent during implantation.
3 US20080097349A1 04/24/2008 Boston Scientific Scimed, Inc. Partially soluble implantable or insertable medical devices In previous attempts to develope a uerteral stent, encrustation was the problem associated with the stent. Along with this pain and discomfort by stent implantaion was there. Here the device (Stent) is provided with at least one surface that contains one or more depressions, which are at least partially filled with a soluble material. This makes stent more flexible and soft after implantation hence minimizing pain and discomfort after implantation or insertion.
4 US5554147A 09/10/1996 CApHCO, Inc. Compositions and devices for controlled release of active ingredients During implantation of ureteral stent,pain and discomfort are the problem with previous stents. Also microbial or bacterial infection at the site of implantation was the problem. In this invention stent is povided with a pH sensitive coating that includes antimicrobial agent to stop the infection. This coating also has the hydrogel property which Upon swelling, the hydrogel's coefficient of friction is reduced, and the polymer becomes slippery, this mechanism reduces the discomfort.
5 US6468649B1 10/22/2002 Scimed Life Systems, Inc. Antimicrobial adhesion surface In prior art problem was the lack of the device which can remain in vivo for extended periods of time without losing its antimicrobial efficacy and which can provides protection against bacterial and fungal organisms for extended periods of time without leaching substances into a patient. This invention provides a medical device with a hydrophobic coating that inhibits the growth of microbes for extended period of time.
6 US20030153983A1 08/14/2003 Scimed Life Systems, Inc. Implantable or insertable medical device resistant to microbial growth and biofilm formation In previous attempts to develope a ureteral stent with coating the problem was the formation of biofilm and microbial growth. The device of the present invention, therefore, overcomes the disadvantages associated with the use of coatings as discussed above, and provides a reduced risk of biofilm fouling that eventually results in encrustation, occlusion and failure of the device. In this invention medical device comprises at least one biocompatible matrix polymer region and bioactive agents comprising an antimicrobial agent and a microbial attachment/biofilm synthesis inhibitor.
7 US20030139800A1 07/24/2003 None Stent assembly with therapeutic agent exterior banding In earlier attempts for stent with a therapeutic property, the problem was the coating or the sheath (responsible for therapy) may covers side branch arteries, vessels, or other lumens extending from the main lumen in which the stent is installed. The sheath can reduce blood flow to or from the side branch and deliver medication into the side branch where it is unnecessary. This invention provides a stent assembly with exterior banding for delivery of therapeutic agents that would overcome the previous disadvantages. Also this stent assembly which avoids side branch vessel blockage by a sheath, with increased drug storage capacity and allowing delivery of different drugs at different axial and radial locations.
8 US20040117007A1 06/17/2004 STS Biopolymers, Inc. Medicated stent having multi-layer polymer coating The problem associated with previous stent and their implantation was thrombus formation in vicinity of stent. The stent assembly developed in this invention consistently provide therapeutic activity from the surfaces of stents in order to reduce the incidence of restenosis and thrombus formation after coronary stenting procedures in the clinic.
9 WO1990013332A1 11/15/1990 CEDARS-SINAI MEDICAL CENTER STENT WITH SUSTAINED DRUG DELIVERY Problem was to provide an intravascular stent that preserves vessel patency, inhibits luminal narrowing and at the same time stent can deliver a pharmaceutical agent to a specific body site or organ. The stent assembly provided by this invention will release anticoagulants, antiplatelet drugs or drugs that inhibit excessive endothelial cell growth at the placement site, thereby preserving the vessels patency and inhibiting luminal narrowing.
10 WO2001036008A2 05/25/2001 STS BIOPOLYMERS, INC. MEDICAL DEVICES COATED WITH ELASTIC POLYMERIC MATERIAL The lack of flexibility, expandability and lubricity of coating surface was the problem with previous insertable medical device. This invention provides a medical device with a polymeric coating adherent to the covering, such that the coating and covering possess desirable surface characteristics such as lubricity, or lack thereof, as well as flexibility, expandability and elasticity.
