Patent number: 9669163Abstract: A dispensing device and the method of making same for dispensing medicaments to a patient that includes a housing, a first assembly connected to the first end of the housing that includes a body portion, and a penetrating sub-assembly. The first assembly also includes a rate control chip of novel construction that is connected to the penetrating sub-assembly and functions to control the rate of flow of medicinal fluid to the patient. Disposed within the housing is a second assembly that includes a shuttle, a collapsible container carried by the shuttle and a plurality of variable force springs that function to thrust the collapsible container into penetrating engagement with the penetrating member of the penetrating assembly and then to collapse the collapsible container to deliver the medicinal fluid to the patient. Connected to the second end of the housing is a novel third assembly that includes an operating member that functions to controllably move the shuttle forwardly of the housing.Type: GrantFiled: October 6, 2015Date of Patent: June 6, 2017Assignee: BioQ Pharma IncorporatedInventors: Ralph I. McNall, III, Thomas T. Donze, Donald B. Bivin

Publication number: 20160199568Abstract: A liquid medicament dispenser includes a housing and a pump carried by the housing, a reservoir applied to the housing and containing a pre-filled sterile liquid medicament, a sterile tubing set routed through the pump, a sterile administration line carried outside of the housing and coupled aseptically to the sterile tubing set in fluid communication, and an aseptic connector coupled to the reservoir and the sterile tubing set and changeable from a storage state to a use state. In the storage state, the aseptic connector prevents the liquid medicament in the reservoir from moving to the sterile tubing set. In the use state of the aseptic connector, the aseptic connector defines a sterile passageway for the flow of the liquid medicament from the reservoir to the sterile tubing set.Type: ApplicationFiled: January 9, 2015Publication date: July 14, 2016Inventors: Ralph I. McNall III, Joshua W. Kriesel, Serena Joshi, Thomas T. Donze

Patent number: 8979842Abstract: Monopolar electrosurgery devices adapted for resecting tonsil and adenoid tissue. The devices minimize thermal injury by employing a plasma generated by pulsed electrical signals to precisely and effectively cut or coagulate the tissues. Suction may also be applied to the tissues to enhance the cutting, coagulation, and tissue manipulation functions. The devices include an interchangeable tip that may be switched for another tip, depending on which tip may be more suitable for tonsillectomy or adenoidectomy.Type: GrantFiled: June 4, 2012Date of Patent: March 17, 2015Assignee: Medtronic Advanced Energy LLCInventors: Ralph I. McNall, III, Kay W. Chang, Paul O. Davison

Patent number: 8870864Abstract: An electrosurgical apparatus includes two assemblies, one of which is the primary assembly intended for a first surgical procedure, such as cutting tissue, and a secondary assembly intended for a second type of electrosurgical procedure, such as tissue coagulation. The secondary assembly fits over the electrode tip of the primary assembly and makes electrical contact with the electrode tip of the primary assembly. This allows for single instrument surgery whereby the secondary (coagulation) assembly provides bleeding control after the primary assembly has cut tissue. This combination significantly reduces operating time. The secondary assembly has a snap fit over the primary assembly so that it may be readily attached and detached several times during any surgical procedure, as the surgeon alternates between cutting tissue and coagulating the resulting incisions using the apparatus.Type: GrantFiled: October 28, 2011Date of Patent: October 28, 2014Assignee: Medtronic Advanced Energy LLCInventors: Paul O. Davison, Ralph I. McNall, III, John R. Tighe, Alexander B. Vankov

Publication number: 20140100557Abstract: Electrosurgical devices including a shaft, a handle and a distal end portion. The distal end portion is formed of an electrically conductive material and includes an electrically insulating material covering a substantial portion of the distal end portion and leaving an exposed portion which acts as an active electrode for delivery of electrical energy to tissue. A conduit in the shaft extending to an opening in the distal end portion facilitates aspiration of tissue and may provide suction simultaneous with delivery of electrical energy. Systems include an electrosurgical device, a source of electrical energy and may optionally include a source of suction and/or a source of fluid delivery or irrigation.Type: ApplicationFiled: March 12, 2013Publication date: April 10, 2014Applicant: MEDTRONIC ADVANCED ENERGY LLCInventors: Michelle Bohner, Ralph I.

Publication number: 20120065594Abstract: A fluid introduction system includes an introducer configured to create a pressure of at least 69 kPa within a spine, and an operator configured to actuate the introducer to introduce fluid into the spine according to a predetermined fluid introduction profile. The system can include a computer readable medium having code for receiving fluid introduction data indicative of a fluid introduction parameter, and for receiving response data indicative of a response of the patient at a time related to a time of the fluid introduction data. A method for introducing fluid includes positioning a first introducer in a first portion of a spine, positioning a second introducer in a second, different portion of the spine and, without removing the first and second introducers, introducing fluid into the first portion of the spine with the first introducer and introducing fluid into the second portion of the spine with the second introducer.Type: ApplicationFiled: September 12, 2011Publication date: March 15, 2012Applicant: NEUROTHERM, INC.Inventors: Nelson SCARBOROUGH, John V.
