| 20080300668 | STENT/FIBER STRUCTURAL COMBINATIONS - A plurality of endoluminal segments axially connected by fiber bridges is disclosed. The endoluminal segments may either be balloon-expandable or self-expanding, with the preferred embodiment being superelastic nitinol. The intraluminal segments may possess a textured surface or at least one geometric feature per segment, preferably located at the apex of a strut pair comprising the intraluminal segment, preferably capable of serving as an anchoring point for the fiber bridges. These geometric features may transmit axially compressive loads during deployment from a device such as a catheter, and may further be capable of interlocking the endoluminal segments when constrained within a device such as a catheter. The fibers comprising the bridges may be polymeric, silk, collagen, bioabsorbable, or a blend thereof. The fiber network comprising the bridges may be regularly oriented, randomly oriented, localized, or continuous. Moreover, the intraluminal segments and fiber bridges may be individually impregnated with therapeutic material, or may both be impregnated with therapeutic material. | 12-04-2008 |
| 20090112158 | MEDICAL DEVICE INCLUDING A THIN METALLIC FILM COMPONENT ATTACHED TO A POLYMERIC COMPONENT AND ASSOCIATED METHODS - A medical device including a medical device thin metallic film component (such as a thin metallic angioplasty balloon), with perforations therethrough, attached to a medical device polymeric component (e.g., a polymeric tubular catheter) abutting the thin metallic film component. The medical device also includes a polymeric sleeve covering the perforations and at least a portion of the polymeric component abutting the thin metallic film component. Moreover, the polymeric sleeve intrudes into the perforations and joins the thin metallic film component to the polymeric component. A method for attaching a medical device thin metallic film component (for example a thin metallic film angioplasty balloon) to a medical device polymeric component (e.g., a tubular polymeric catheter) includes forming a plurality of perforations in the medical device thin metallic film component and abutting the medical device polymeric component against the medical device thin metallic component. Subsequently, a polymeric sleeve is applied over the perforations and at least a portion of the abutted medical device polymeric component. Heat and/or pressure is then applied to the polymer sleeve in a manner that results in the polymer sleeve being joined to the medical device thin metallic film and the portion of the abutted medical device polymeric component and the polymer sleeve flowing into the perforations, thereby attaching the medical device thin metallic film component to the medical device polymeric component. | 04-30-2009 |
| 20090112306 | STENT SEGMENTS AXIALLY CONNECTED BY THIN FILM - In accordance with the present invention, there is provided a stent for insertion into a vessel of a patient. The stent has a front and back open ends and a longitudinal axis extending therebetween. The stent has a plurality of adjacent hoops that are held in alignment with the longitudinal axis between the front and back open ends by a thin film tube. The hoops are attached to either the inner or outer surface of the thin film tube. The stent is compressed into a first smaller diameter for insertion into the vessel with a delivery tube and a second larger diameter for deployment into the vessel. The inventive stent can be retracted into the delivery tube if it is improperly deployed. | 04-30-2009 |
| 20090149835 | MEDICAL DEVICE INCLUDING A METALLIC SUBSTRATE COMPONENT ATTACHED TO A POLYMERIC COMPONENT AND ASSOCIATED METHODS - A medical device including a medical device metallic substrate component, with perforations therethrough, attached to a medical device polymeric component abutting the thin metallic film component. The medical device also includes a polymeric sleeve covering the perforations and at least a portion of the polymeric component abutting the metallic substrate component. Moreover, the polymeric sleeve intrudes into the perforations and joins the metallic substrate component to the polymeric component. A method for attaching a medical device metallic substrate component to a medical device polymeric component includes forming a plurality of perforations in the medical device metallic substrate component and abutting the medical device polymeric component against the medical device metallic substrate component. Subsequently, a polymeric sleeve is applied over the perforations and at least a portion of the abutted medical device polymeric component. Heat and/or pressure is then applied to the polymer sleeve in a manner that results in the polymer sleeve being joined to the medical device metallic substrate and the portion of the abutted medical device polymeric component and the polymer sleeve flowing into the perforations, thereby attaching the medical device metallic substrate component to the medical device polymeric component. | 06-11-2009 |
| 20100043199 | STENT SEGMENTS AXIALLY CONNECTED BY THIN FILM - In accordance with the present invention, there is provided a stent for insertion into a vessel of a patient and a method for manufacturing the same. The stent has front and back open ends and a longitudinal axis extending therebetween. The stent has a plurality of adjacent hoops that are held in alignment with the longitudinal axis between the front and back open ends by a thin film tube. The hoops are attached to either the inner or outer surface of the thin film tube. The stent is compressed into a first smaller diameter for insertion into the vessel with a delivery tube and a second larger diameter for deployment into the vessel. The inventive stent can be retracted into the delivery tube if it is improperly deployed. | 02-25-2010 |
| 20100131048 | EXPANDABLE SLIDE AND LOCK STENT - An expandable slide and lock stent is provided that comprises a plurality of radial elements interconnected to form a tubular member. Each radial element can comprise a helical backbone and at least one elongate member extending from the helical backbone in a circumferential direction. Each backbone can have at least one slot that can be configured to receive an elongate member of an adjacent radial element. | 05-27-2010 |
| 20110106237 | ALTERNATING CIRCUMFERENTIAL BRIDGE STENT DESIGN AND METHODS FOR USE THEREOF - A stent includes a first section and a second section. The first section and the second section each include a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices, and each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. In some aspects, the first section is more flexible along the longitudinal axis of the stent than the second section and is configured to be placed in a specific region of a vessel that requires flexibility to accommodate surrounding anatomy. In some aspects, the first section is more radially stiff than the second section and is configured to be placed in a specific region of the vessel that requires radial stiffness to counteract crushing force caused by surrounding anatomy. | 05-05-2011 |
