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:
A plurality of sensors are used to sense disturbances in a data storage system. An adaptive gain component is associated with each of the sensors and provides a gain for each of the sensor signals. The gain of each sensor signal is adapted, individually, based on a correlation of each given sensor signal to the position error signal. This adaptation produces a position correction signal. The position correction signal is applied to a position signal that is used to position the reading and writing components and the storage medium relative to one another. This compensates for both rotary and linear vibration disturbances at the same time.
Abstract:
Medical assemblies with a releasable connection and methods of constructing such medical assemblies are disclosed. The medical assemblies generally comprise a stent, a catheter assembly having catheter body a balloon, and a releasable connection between the stent and the catheter assembly that releases the stent from the catheter assembly in response to enlargement of the balloon or when the balloon has been enlarged to an expanded configuration.
Abstract:
Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stent manufacture and fabrication of a stent therefrom are disclosed.
Abstract:
Stents fabricated from hydrolytically degradable polymers with accelerated degradation rates and methods of fabricating stents with accelerated degradation rates are disclosed.
Abstract:
A method of treating a bodily lumen with a stent including disposing a stent within a bodily lumen in which the stent has a plurality of deformable struts that are substantially circumferentially aligned is described. The deformable struts are configured to selectively deform in a circumferential direction in localized regions in the struts upon application of an outward radial force. The stent is expanded by applying the outward radial force which causes selective deformation of the deformable struts in a localized region in the struts.
Abstract:
Methods and systems of fabricating a polymeric stent are disclosed herein. Methods are disclosed that include forming a polymeric tube using extrusion, radially deforming the formed tube so that the deformed tube comprises a target diameter, forming a stent from the deformed tube, and forming a stent from the deformed tube. The stent is formed by laser machining a stent pattern in the deformed tube with an ultra-short pulse laser. Disclosed methods further include crimping the stent on a support element, wherein a temperature of the stent during crimping is above an ambient temperature.
Abstract:
The present invention provides electrically conductive paper composites prepared from cellulose fibers modified to bind a conducting polymer to a surface of the cellulose fibers and mixing these with unmodified cellulose fibers and forming paper products from the composite. Conducting paper composites so formed were investigated for their conductivity and strength properties as a function of monomer dosage or percentage of modified fibers in the mixture and for the composites it was found that less monomer (i.e. conductive polymer) was needed to achieve the same conductivity obtained from conducting paper made from only the modified cellulose. A higher tensile strength was obtained with the composite conducting paper than was attained with conducting paper made from only the modified cellulose. The electrically conductive paper composites may also be prepared from cellulose fibers mixed with particulate fillers modified to bind a conducting polymer to a surface of the particulate fillers.
