  • Publication number: 20130284310
    Abstract: Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent.

  • Patent number: 8460745
    Abstract: Methods and apparatus are disclosed for loading a therapeutic substance or drug within a lumenal space of a hollow wire having a plurality of side openings along a length thereof that forms a hollow drug-eluting stent with a plurality of side drug delivery openings. Loading a drug within the lumenal space of the hollow stent includes a drug filling step, in which the drug is mixed with a solvent or dispersion medium. The lumenal space may be filled with the drug solution or suspension in a reverse fill process and/or a forward fill process. After the drug filling step, a solvent or dispersion medium extracting step is performed to extract the solvent or dispersion medium from within the lumenal space such that only the drug remains within the hollow stent. A stent cleaning step may be performed to an exterior surface of the hollow stent.

  • Patent number: 8460238
    Abstract: A drug delivery catheter and method for delivering microcapsules or microspheres containing a drug, pharmacological or other bioactive agent includes a balloon catheter having a coating on the balloon of a soluble biocompatible polymer containing a plurality of microcapsules or microspheres containing a drug or other agent. The balloon is porous to allow it to be inflated with a solvent fluid that passes through the porous wall of the balloon and dissolves the polymer, releasing the microspheres.

  • Publication number: 20110264186
    Abstract: A hybrid stent prosthesis including a biodegradable tubular body, a first non-biodegradable self-expanding ring coupled to a proximal end of the biodegradable body, and a second non-biodegradable self-expanding ring coupled to a distal end of the biodegradable body. The hybrid stent includes a mechanism for longitudinally compressing the tubular body to increase the radial or hoop strength thereof. The longitudinally compressing mechanism may be protruding elements coupled to and extending radially outward from the hybrid stent or elastomeric compression bands or tethers extending between the non-biodegradable rings. The compression bands may be pre-connected to both non-biodegradable rings prior to stent delivery, or may be connected to one non-biodegradable ring prior to insertion and connected to the other non-biodegradable ring in situ.

  • Publication number: 20110018199
    Abstract: A board game with a continuous track separated into discreet steps uses a random number device to determine an advancement of players' tokens. Designated game events reflect life occurrences and choices. A monetary currency is gained and lost. A second, non-monetary, currency is also gained and lost. That second currency is representative of a player's health status and is not freely exchangeable with any pecuniary currency. While a pecuniary currency is useful in securing the health representative currency, in scoring and in determining winners and losers only the health related currency is determinative.

  • Publication number: 20100268191
    Abstract: A drug delivery catheter and method are provided for delivering drugs to a targeted region of a lumen include drug-laden microcapsules provided within a porous catheter balloon with an effective pore size that prevents free-flow of the microcapsules through the porous wall of the balloon. The microcapsules are frangible under the influence of increased pressure within the balloon. In an alternative embodiment, the microcapsules may be mechanically ruptured by compression between the outer porous balloon and optional, inner, non-porous balloon. The drug is emitted from the microcapsules through the balloon pores and against the targeted luminal surface.
