  • Patent number: 8623025
    Abstract: The invention relates to a systems, devices and methods of delivering and deploying a stent into a curvilinear cavity within a vertebral body or other bony or body structure. In some instances, a system can include an elongate shaft for delivering a self-expanding, cement-directing stent. The elongate shaft can include at least one of an inner shaft, an outer shaft, a tubular sheath, a flexible guidewire, and an internal polymer extrusion. A rotational handle can be used to control movement of the elongate shaft. The rotational handle can incorporate one or more pins in slots associated with each of the components (e.g., inner shaft, outer shaft, and tubular sheath), such that upon rotation of the handle, the pins are forced to move in the direction of their respective slots.

  • Publication number: 20130231676
    Abstract: Stabilizing an object in the body of a patient involves the injection of a lower critical solution temperature (LCST) material or other flowable material into the body of the patient so that the material contacts the object. The LCST material or other flowable material then forms a gel in the body such that the object is contained at least partially within the gel and thereby stabilized by the gel such that the object can then be easily fragmented within the body and/or retrieved from the body.

  • Patent number: 8481138
    Abstract: Implantable or insertable medical devices that provide resistance to microbial growth on and in the environment of the device and resistance to microbial adhesion and biofilm formation on the device. In particular, the implantable or insertable medical devices include at least one biocompatible matrix polymer region, an antimicrobial agent for providing resistance to microbial growth and a microbial adhesion/biofilm synthesis inhibitor for inhibiting the attachment of microbes and the synthesis and accumulation of biofilm on the surface of the medical device. Methods of manufacturing such devices under conditions that substantially prevent preferential partitioning of any of said bioactive agents to a surface of the biocompatible matrix polymer and substantially prevent chemical modification of said bioactive agents.

  • Publication number: 20120253451
    Abstract: A medical device includes a balloon catheter having an expandable member, e.g., an inflatable balloon, at its distal end and a stent or other endoprosthesis. The stent is, for example, an apertured tubular member formed of a polymer and is assembled about the balloon. The stent has an initial diameter for delivery into the body and can be expanded to a larger diameter by inflating the balloon.

  • Patent number: 8025943
    Abstract: A dilatation balloon and catheter for insertion into a bodily conduit. The catheter (10) includes shaft (12) and a dilatation balloon (24) at the distal end of the shaft. The balloon is inflated via a central lumen (14) in the shaft for delivery of a fluid inflation media. The balloon is fabricated from a combination of a thermoplastic elastomer (TPE), preferably an engineering thermoplastic elastomer (ETE), with a non-compliant structural polymeric material. The combination may be a blend of the non-compliant structural polymer and the TPE. Alternatively, the combination may be a layered balloon having, for example, a non-compliant structural polymer inner layer and a soft, abrasion resistant, elastomeric outer layer. Methods for fabricating the balloon from the combination of a TPE and a non-compliant structural polymer are also disclosed.
