A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a needle driver at a distal end of the drive arm, wherein the needle driver is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the needle driver, thereby rotating the suturing needle about the rotational axis.

Systems and methods for tissue closure

Apparatus and method for tissue closure

A method of modifying the surface of a medical device to release a drug in a controlled way by providing a barrier layer on the surface of one or more drug coatings. The barrier layer consists of modified drug material converted to a barrier layer by irradiation by an accelerated neutral beam derived from an accelerated gas cluster ion beam. Also medical devices formed thereby.

Drug delivery system and method of manufacturing thereof

A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a drive mechanism at a distal end of the drive arm, wherein the drive mechanism is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the drive mechanism, thereby rotating the suturing needle about the rotational axis.

Suturing needle

A method of preparing a preformed bone shape for implantation provides irradiating at least a portion of a preformed bone shape by a Neutral Beam derived from a GCIB, and the preformed bone shape so irradiated.

Method for modifying the wettability and other biocompatibility characteristics of a surface of a biological material by the application of beam technology and biological materials made thereby

In one embodiment, a drug delivery system and method provide a member including a combination of a drug substance and a polymer or other material, and an encapsulating layer formed in an outer surface of the member by gas cluster ion beam irradiation of the outer surface of the member, which encapsulating layer is adapted to determine one or more characteristics of the drug delivery system.

A method for producing a drug delivery system provides a member including a combination of a drug substance and a polymer or other material; and forms a layer on a surface of the combination using gas cluster ion beam irradiation, which layer determines a release rate for the drug substance, wherein the layer is an encapsulating layer formed by densifying or carbonizing components of the drug or of the polymer or of the other material by the gas cluster ion beam irradiation.

Method of manufacturing a drug delivery system using gas cluster ion beam irradiation

Apparatus and method for sternotomy closure

A method of controlling the drug release rate of a drug coated endovascular stent by depositing a drug material layer on the stent and then modifying the drug material using gas cluster ion beam irradiation to create a carbon matrix with interstices containing the original drug. The rate at which the drug elutes through the interstices can be controlled by processing parameters. Multiple layers may be employed to create time varying release rates.
