  • Patent number: 10987452
    Abstract: A method and device for local delivery of water-soluble or water-insoluble therapeutic agents to the surface of a normal or diseased body lumen is disclosed. An expandable structure of a medical disposable device, such as a balloon of a balloon catheter, is coated with an amphiphilic polymer coating comprising a therapeutic agent and an amphiphilic polymer or co-polymer. The medical disposable device is inserted into a body lumen, and expanded to contact the amphiphilic polymer coating against the body lumen. The total solubility of the polymer or co-polymer in vivo prevents any embolic hazard associated with the amphiphilic polymer coating.

  • Patent number: 9775930
    Abstract: A bioscaffolding can be formed within a post-myocardial infarct region sufficient to cause attenuation of a rate of myocardial infarct expansion. A bioscaffolding may further be formed in the post-myocardial infarct region to cause an increase in posterior left ventricular wall thickness. The gel or bioscaffolding can be formed from a mixture of gel components of different gelation systems. For example, a bioscaffolding can be formed by mixing at least two different components of at least two different two-component gelation systems to form a first mixture and by mixing at least two different components (other than the components that make up the first mixture) of the at least two different two-component gelation systems to form a second mixture.

  • Patent number: 9656030
    Abstract: A method including percutaneously positioning a delivery device in a blood vessel; locally introducing a treatment agent from the delivery device into the blood vessel upstream of an infarcted area or distressed area; and following introducing the treatment agent, occluding the blood vessel for a dwell time sufficient to allow the treatment agent to flow into targeted capillaries in or adjacent to the infarcted area. A system comprising a delivery device suitable for percutaneous insertion into a blood vessel of a patient, the delivery device comprising an occluding portion and a delivery cannula having a lumen therethrough; a controller coupled to a proximal portion of the delivery device comprising instruction logic to perform a method including introducing a treatment agent into the delivery cannula; and occluding a blood vessel following a predetermined delay time after introducing the treatment agent.

  • Patent number: 9533127
    Abstract: A method that includes introducing a catheter assembly to an obstructed region of a blood vessel lumen and recanalizing the obstructed region with the catheter assembly is disclosed. Prior to or during recanalization, a treatment agent may be delivered through the catheter assembly to a vessel region downstream to the obstructed region. The treatment agent may have a property that will inhibit reperfusion injury. Alternatively, a medical device may be introduced to an obstructed region of a blood vessel lumen and the obstructed region recanalized with the medical device. The treatment agent may be delivered to a vessel region downstream to the obstructed region. The treatment agent may include at least one of an immunosuppresant and an antioxidant.

  • Patent number: 9402814
    Abstract: A method is described including passing a solution having a biodegradable polymer, a solvent and a treatment agent through an electrocharged nozzle to form particles encapsulating the treatment agent. The particles emitted from the electrocharged nozzle may be exposed to a charge opposite that of the nozzle. The particles may be deposited in a collection assembly comprising a liquid phase. A further method including combining a biodegradable polymer, a solvent and a treatment agent to form a solution, electrodepositing the solution in a particle form wherein the particles encapsulate the treatment agent in a collection assembly comprising a liquid phase and mixing the particles with a bioerodible material capable of forming a gel is described. An apparatus having an electrocharged nozzle, a grounded electrode having an opposite charge to that of the nozzle and a collection assembly comprising a liquid phase is further disclosed.
