  • Patent number: 10661022
    Abstract: A substance delivery device that includes a hypodermic needle with a tube for receiving and containing a volume of a substance. The substance delivery device includes a rod, a portion of which is of a size and shape to fit within the tube of the hypodermic needle. The rod can be displaced into and within the tube to contact and apply a force to a volume of substance contained within the tube to cause, at least in part, the volume of substance to be discharged out of the tube. The substance delivery device includes a rod displacement mechanism that applies a force to the rod to cause the rod to be displaced into and within the tube. The substance delivery device also includes a needle retraction mechanism that is configured to apply a force to the hypodermic needle to cause the hypodermic needle to retract from within a patient.

  • Patent number: 10188533
    Abstract: A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease is formed as a thin, annular band of durable, flexible material having a plurality of focal elevating elements on its outer annular periphery for holding loose plaque under a spring or other expansion force against a blood vessel wall. The focal elevating elements are designed to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the intraluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

  • Patent number: 9694135
    Abstract: A revolving multi-cartridge syringe device includes a needle and two or three revolving holders, each for receiving a cartridge containing medical fluid to be injected. The holders can be pre-loaded with the cartridges, with a first cartridge placed in a loaded position ready to dispense. After fluid in the first cartridge is injected into a patient, a second holder and cartridge are revolved into the loaded position, without breakdown of the syringe. The process can be repeated with a third cartridge. The engagement of each cartridge with the needle, retraction from the needle, and rotation of the revolving holder are all implemented by sliding a sliding actuator in either a first direction or a second, opposite, direction, depending on which action is desired. Thus, injection and reloading of the cartridges can be easily actuated by the user through manipulation of a single slidable actuator, without requiring withdrawing the needle from the mouth area to reload.

  • Patent number: 8389023
    Abstract: Novel methods for the chemical ablation of tissue (e.g. prostatic tissue) are described. These methods include the steps of: (a) providing one or more solid salt dosage form comprising 50-100% w/w salt; and (b) inserting one or more of such solid salt dosage forms into the tissue. The solid salt dosage form is optionally inserted into the tissue under real-time ultrasonic observation. An advantage of the present invention is its ability to eliminate toxic byproducts. For example, where NaCl-based solid salt dosage forms are used to effect localized chemical ablation, the concentration is ultimately reduced to the level of normal saline (i.e., about 0.9%) upon absorption by the body of the subject being treated.

  • Patent number: 5997500
    Abstract: A pneumatically operated veterinary medicinal pellet implanter utilizes pressurized air to drive an impeller for dispensing medicinal pellets through a needle on an end of the implanter and into a cavity created by the needle under the skin of an animal to be treated. The pressurized air source may also be utilized to retract the impeller after dispensing of the pellets. The impeller is part of a piston slidingly secured within a pneumatic cylinder. Pressurized air is selectively and alternatingly supplied to the front and rear and rear of the cylinder for advancing the impeller between retracted and extended positions respectively. The pressure of the air supplied to the rear of the cylinder for driving the impeller is reduced relative to the pressure of the air supplied to the front of the cylinder for retracting the impeller.

  • Patent number: 5971951
    Abstract: Devices for the generation of inhalable aerosols by extrusion through a porous membrane by a motor-driven cam assembly are disclosed. The device holds a drug formulation container in a drug release position. The package is comprised of a collapsible wall with an opening and a cover for the opening that includes a porous membrane having a plurality of pores therein with a diameter in the range of 0.5 to 6.0 microns. An electric motor in the device is powered by a battery to rotate a cam assembly having three cams. The first cam forces a clamping member (configured to correspond to the outer periphery of the container) against the periphery of the collapsible wall of the container, sealing the jointure of the collapsible wall to the cover of the container along the entire periphery, except for a small unsealed portion thereof. The second cam crushes the collapsible wall, forcing the contents of the container through the unsealed portion of the jointure.

  • Patent number: 5817054
    Abstract: A veterinary implanter includes an attached disinfectant dispenser including a reservoir for holding a quantity of disinfectant, a pump attached to the reservoir, and a special needle holder spray tip with the implanter including a conduit which has an inlet opening connected to the disinfectant pump. An exit opening of the conduit is coupled to the needle spray tip which is designed to spray disinfectant 360 degrees about the inlet end of a hypodermic needle cannula which is held in place against the spray tip by a threaded needle holder extension. The inventive disinfectant dispenser thus allows an operator of the implanter to selectively inject a quantity of disinfectant into the needle with each implant, with the disinfectant then being carried by the implanted pellets into a wound created by the needle.

  • Patent number: 5213573
    Abstract: An apparatus for determining whether an IV infusion set has infiltrated the tissue of a patient includes a pump for pumping fluid through the IV set into the patient and a pressure transducer operably engaged with the IV set between the pump and patient. The pressure transducer is electrically connected to a microprocessor, and the microprocessor is electrically connected to the motor of the pump to control the pump to alternately withdraw from and infuse into the patient a predetermined volume of fluid.This predetermined volume of fluid is withdrawn from the patient by the pump at a preselected withdrawal pressure, while the pump infuses the predetermined volume of fluid into the patient at a preselected infusion pressure. The microprocessor measures both the time period for infusing the predetermined volume of fluid and the time period for withdrawing the predetermined volume of fluid. Based upon these time periods, the microprocessor evaluates whether the IV set has infiltrated the patient's tissue.
