A ureteral stent is provided. The stent may include a first section having a first wall defining a first luminal section. The stent may further include a second section having a second wall defining a second luminal section. The second section can be enabled to substantially close at times external pressure is applied to the stent.

Ureteral stent

Disclosed herein is ureteral stent. The ureteral stent includes a proximal end, a distal end, and a middle portion. The proximal end includes a retention feature having a coiled shape. The distal end is opposite the proximal end. The middle portion is between the proximal end and the distal end.

Provided is a ureteral stent comprising certain amount of ethylene-vinyl acetate polymer and a certain amount of an additive selected from barium sulfate, bismuth subcarbonate, bismuth oxychloride, a polyolefin elastomer, a thermoplastics elastomer, and a mixture thereof. The provided stent may have multiple layers such as inner layer and outer layer with each layer having different elastic modulus. Also provided is a method of making the aforementioned ureteral stent and a method of using the ureteral stent in treating kidney or bladder related diseases.

Fatty acid-based, pre-cure-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.

Cross-linked fatty acid-based biomaterials

A ureteral stent that includes a tubular member and a retaining end adapted to be placed inside a kidney or a bladder of a patient. The retaining end includes a plurality of loops. Each of the loops are centered about a loop axis, and two or more of the loop axes extend in different directions relative to other loop axes.

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.

Ureteral stents include a tubular body defining a lumen and have a distal kidney section, a proximal bladder section, and a ureter section between the distal and proximal sections. The tubular body has a first material layer and a stiffening member that extends through at least a portion of a length of the tubular body. The stiffening member has a stiffness characteristic that varies along its length. This enables different portions of the stent to have different stiffness characteristics that preferably are optimized for the location of those portions within the human body. The stiffening member may be at least a second material layer having a second stiffness that is different from a first stiffness of the first material layer, and/or at least one strand of material that is embedded within the first material layer.

Ureteral stents with waveform interlayers and interstitching

Provided are methods, systems, and kits of properly delivering a biodegradable stent into a body lumen of a subject. More particularly, provided are methods, systems, and kits of properly delivering a biodegradable ureteral stent into the kidney and the bladder of a subject. Even more particularly, provided are methods, systems, and kits of properly delivering a chitosan based stent into a body lumen of a subject. Even more particularly, provided are methods, systems, and kits of properly delivering a chitosan based ureteral stent into the kidney and the bladder of a subject.
