Stents, systems, and methods for gastrointestinal tract treatment
The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.
IMPLANTABLE MEDICAL DEVICE WITH REDUCED MIGRATION CAPABILITIES
Medical devices and methods for making and using a medical device are disclosed. An example medical device may include a stent that comprises a first covered region formed of one or more interwoven filaments and a covering. The stent may also comprise a second uncovered region adjacent the first covered region. The second uncovered region may include a knitted filament. A first end of the knitted filament may be attached to the first covered region. The knitted filament is configured to be unraveled to remove both the first covered region and the second uncovered region of the stent while the first end of the knitted stent remains attached to the first covered region.
Layer having variable strength
A layer having individual elements made of an elastic material, with the length thereof exceeding the diameter thereof, which are secured on a carrier at a distance to one another, wherein the elements can be moved towards and away from one another, the elements can contact when moving towards one another, the outer surfaces of the elements provided with a surface modification, and the surface modification containing substances that can form reversible, non-covalent bonds. Also, a method for producing the layer, and the use of the layer.
STENT GRAFT WITH EXTERNAL SCAFFOLDING AND METHOD
A scaffolded stent-graft includes a graft material comprising an inner surface and an outer surface. The inner surface defines a lumen within the graft material. The scaffolded stent-graft further includes a scaffold comprising a mesh coupled to the graft material at the outer surface. The scaffold is configured to promote tissue ingrowth therein. In this manner, the scaffold enhances tissue integration into the scaffolded stent-graft. The tissue integration enhances biological fixation of the scaffolded stent-graft in vessels minimizing the possibility of endoleaks and migration.
Implantable heart valve devices, mitral valve repair devices and associated systems and methods
Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet.
PATTERNS FOR FLOW CONTROL AND BIOADHESION CONTROL
Disclosed herein is an article including a path that extends across at least a portion of a surface of the article, the path being defined by at least one channel that traverses at least a portion of the surface or a first plurality of spaced features disposed on or in at least a portion of the surface; the spaced features arranged in a plurality of groupings; the groupings of features comprising repeat units; the spaced features within a grouping being spaced apart at an average distance of about 1 nanometer to about 500 micrometers to define a path that traverses the plurality of spaced features; each feature having a surface that is substantially parallel to a surface on a neighboring feature; each feature being separated from its neighboring feature; the groupings of features being arranged with respect to one another so as to define a tortuous pathway.
Method and system for patella tendon realignment
A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, and an anterior portion. The superior portion being configured to reside below a patellar tendon and to elevate and/or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes affixing the implant.
Soft tissue repair prosthesis and expandable device
A hernia repair device is provided which may include a soft tissue repair prosthesis and an expandable device configured to be removably connected with the soft tissue repair prosthesis. Attachment components may be used to removably connect the soft tissue repair prosthesis with the expandable device. The hernia repair device may be manipulated into a reduced configuration for insertion into the body. When expanded, the expandable device may be configured to position the soft tissue repair prosthesis adjacent a hernia defect. The expandable device and/or the attachment components may be shaped and/or configured to minimize the maximum dimension of the hernia repair device in its reduced configuration.
Method and apparatus for creating a reconstructive graft
A method and apparatus is provided for creating an internal reconstruction tissue graft. Templates may be used to create a multitude of patterns in a variety of tissue reconstruction grafts. An apparatus may be used to create an internal tissue graft for reconstruction through either compression and/or removal of segments. An apparatus may be used, through either compression and or removal of segments of a preformed template made of synthetics and or metal that mirrors a template that can be used as an internal tissue graft for reconstruction. In a method, such as using software analysis and an apparatus, the physical properties of the tissue graft and its pre- and post-operative properties and appearance may be measured.
Superhydrophobic coating for airway mucus plugging prevention
A method for reducing mucus accumulation in an airway including disposing an implantable device within an airway, wherein the implantable device has a first end, a second end, and an inner surface defining a lumen extending from the first end to the second end; wherein at least a portion of the inner surface has a hydrophobic polymer coating thereon, wherein a polymer coating surface has dynamic water contact angles of 145 degrees or greater; and wherein the implantable device is constructed and arranged to maintain patency of the airway; wherein accumulation of mucus is reduced as compared to a similar implantable device without the hydrophobic portion of the inner surface. An implantable medical device having a superhydrophobic surface and a method of making an implantable medical device having a superhydrophobic surface are also provided. An implantable medical device having a micropatterned surface with enhanced adhesion to tissue, optionally in combination with other region(s) having a superhydrophobic surface and a method of making such a device.
