| 20100268325 | MEDICAL DEVICES AND METHODS OF MAKING THE SAME - Medical devices, such as endoprostheses, and methods of making the devices are disclosed. In some embodiments, an endoprosthesis includes a first portion having a first width, and a second portion having a second width different than the first width, wherein the first and second portions have different grain sizes. | 10-21-2010 |
| 20110245905 | ENDOPROSTHESIS - Among other things, a bio-erodible implantable endoprosthesis comprises a member that includes (a) a core having a surface, and (b) a bio-erodible metal on a least a portion of the surface of the core, wherein the bio-erodible metal erodes more slowly than the core and includes openings through which physiological fluids can access the core upon implantation. | 10-06-2011 |
| 20120095548 | MEDICAL IMPLANT INCLUDING A MAGNESIUM-BASED TIE LAYER - A medical implant includes a metallic base, a tie layer, and at least a first layer overlying an outer surface of the tie layer. The tie layer is bonded to at least a portion of a surface of the metallic base. The tie layer includes magnesium or a magnesium-based alloy. The tie layer can have an outer surface comprising dendritic grains. The tie layer can have a rough outer surface defined by pores, projecting grain structures, and/or projecting particles. A method of producing a tie layer on a medical device includes applying magnesium or a magnesium-based alloy to the medical device and cooling the magnesium or the magnesium-based alloy to produce a rough outer surface. | 04-19-2012 |

| 20080215136 | DIFFERENTIAL DRUG RELEASE FROM A MEDICAL DEVICE - The invention relates to a medical device, such as an intravascular stent, useful for delivering two or more therapeutic agents to a body tissue of a patient at different rates, and methods for making and using such medical device. The medical device includes a substrate and/or coating having a plurality of pores, dispersed in said pores are a plurality of a first and second therapeutic agents, wherein said first therapeutic agent is bonded to one or more molecule(s) of a first material and the second therapeutic agent bonded to one or more molecule(s) of a second material, such that when the medical device, is in use (e.g., implanted into a body lumen such as a blood vessel), bonded first therapeutic agent is released from the medical device at a rate that is slower than the rate at which the bonded second therapeutic agent is released from the medical device. | 09-04-2008 |
| 20090118820 | DEFORMABLE UNDERLAYER FOR STENT - An endoprosthesis includes a brittle layer, e.g. a ceramic and an underlayer to accommodate dimensional changes as the endoprosthesis is flexed. | 05-07-2009 |
| 20090216185 | BALLOON CATHETER WITH DURABLE TIP PORTION - A durable distal tip structure for an intravascular catheter that may include a distal portion comprising a ring of durable material configured to provide a durable distal tip to the catheter, and a proximal portion extending proximally from the distal portion and configured for connecting the distal tip structure to the catheter, wherein the proximal portion of the distal tip structure is more laterally flexible than the distal portion. In some cases, the durable distal tip structure comprises a metal or metal alloy, and in some cases, the distal ring portion and proximal portion of the durable distal tip structure comprise a single monolith of material. Also, catheters including such durable distal tip structures, and methods of making and using such catheters. In some cases, the catheter is a balloon catheter. In some other embodiments, the catheter is a stent delivery catheter for a self expanding stent. | 08-27-2009 |
| 20100137977 | Coating for Medical Device Having Increased Surface Area - Described herein are implantable medical devices for delivering a therapeutic agent to the body tissue of a patient, and methods for making such medical devices. In particular, the implantable medical devices, such as intravascular stents, have a coating which includes at least one coating composition and has an exposed abluminal surface and an exposed luminal surface or exposed side surface. | 06-03-2010 |
| 20110009942 | BALLOON CATHETER - Balloon catheters and stent delivery systems including bifurcated stent delivery systems are disclosed. An example bifurcated stent delivery system may include an elongate shaft including a proximal section, a midshaft section, and a distal section. The proximal section may include a tubular member having a plurality of slots formed therein. The slots may be arranged in one or more sections having differing slot densities. The midshaft section may include a guidewire port in fluid communication with a guidewire lumen formed in the shaft. A main branch balloon may be coupled to the shaft. A side branch balloon may be disposed adjacent to the main branch balloon. A stent may be disposed on the main branch balloon and on the side branch balloon. | 01-13-2011 |
| 20110301574 | ADJUSTABLE STIFFNESS CATHETER - Medical devices such as catheters can include structure or provision that permit a physician or other health care professional to adjust the stiffness of at least a portion of the medical device. In some instances, the medical device may be adjusted prior to inserting the medical device into a patient. In some cases, the medical device may be adjusted while in use within the patient. | 12-08-2011 |
