Abstract:
Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.

Abstract:
An apparatus and method for supporting a plurality of components, at least one of which is a heat-generating electrical device such as a power semiconductor device, are disclosed. In some embodiments, the apparatus includes a first structure having a first surface on one side of the structure configured for interfacing a first of the plurality of components and a second surface on another side of the structure, and also includes a second structure capable of receiving the first structure, where one of the second surface and an additional surface of the second structure includes a tip that is in contact with the other of those surfaces. The apparatus further includes at least one component configured to assist in retaining the first and second structures relative to one another, where notwithstanding the at least one component the first structure is capable of pivoting relative to the second structure about the tip.
Abstract:
A mounting apparatus for mounting a drive bracket on which a protruding portion is provided, includes an enclosure, and a mounting member. The enclosure includes a base wall for supporting the drive bracket thereon, a side wall extending from one side of the base wall, and a holder extending from the side wall. The mounting member is movably attached to the holder. The mounting member includes a locking portion extending therefrom for engaging with the protruding portion of the drive bracket.
Abstract:
Provided herein is a method of forming medical device that includes RGD attached to the device via a spacer compound. The method comprises providing a spacer compound comprising a hydrophobic moiety and a hydrophilic moiety, grafting or embedding the spacer compound to the surface layer of the polymer to cause the hydrophobic moiety to be grafted to or embedded within the surface layer of polymer, and attaching a chemo-attractant to the hydrophilic moiety.
Abstract:
A method of manufacturing a radially expandable an implantable medical device, the method comprising: providing a plurality of fibers, the fibers comprising a polymer; disposing the plurality of fibers on a cylindrical support element to form a tubular structure, the tubular structure having an initial diameter; heat setting the tubular structure such that the temperature of the tubular structure is between Tg to Tm of the polymer while heat setting, wherein the tubular structure is maintained at a heat set diameter which is equal to or substantially equal to the initial diameter; and fabricating an implantable medical device from the tubular structure.
Abstract:
A medical device such as a stent with a catheter, delivery balloon and an infrared energy source is disclosed. The infrared energy source heats the delivery balloon, and/or the stent to a temperature above body temperature, thereby increasing the flexibility of the stent such that formation of cracks in the stent upon its expansion is reduced or eliminated. Either the delivery balloon, and/or the stent may include an infrared energy absorbing material.
Abstract:
A stent includes a marker that has a biodegradable body and a plurality of radiopaque nanoparticles dispersed in the body. The marker is disposed in a hole on a biodegradable structural element of the stent, and the marker and the hole have substantially the same configuration. A method for making a stent includes mixing radiopaque nanoparticles with a biodegradable material to form a stent marker, forming a hole on a structural element of a biodegradable stent for accommodating the stent marker, wherein the stent marker and hole have substantially the same configuration, and disposing the stent marker in the hole.
