Patent number: 7771393Abstract: An insertion device for an infusion set, the insertion device including a two-part housing and a retainer or a retention means by which the infusion set can be temporarily held on the device, and a driver or a drive means including a pretensionable spring for providing the drive energy for an insertion movement of the infusion set, wherein one of the housing parts can be pivoted relative to the other to engage the infusion set and, after engagement of the infusion set, they can be pivoted again, as a result of which the spring is pretensioned and the insertion device is brought to a ready-to-use state. After the insertion movement has been triggered, the infusion set is separated from the device, such that it can execute the greatest part of the insertion movement free of the retainer.Type: GrantFiled: March 13, 2008Date of Patent: August 10, 2010Assignee: Roche Diagnostics International AGInventors: Jurg Liniger, Pascal Rutti, James Collins

Patent number: 7699807Abstract: A device for inserting a cannula of a subcutaneous infusion device into a subcutaneous layer of skin of a patient. For example, some devices automatically retract a needle used to introduce the cannula of a subcutaneous infusion device into the subcutaneous layer of skin of a patient. The device can include a housing with an internal cavity, as well as a needle coupled to the housing. The needle can be coupled to a cannula of a subcutaneous infusion device. A member can move the needle. Upon full introduction of the needle and associated cannula of the subcutaneous infusion device into a subcutaneous layer of skin of a patient, the member is automatically actuated to move the needle into the internal cavity of the housing into the retracted state while leaving the cannula of the subcutaneous infusion device in the subcutaneous layer of skin of the patient.Type: GrantFiled: November 10, 2003Date of Patent: April 20, 2010Assignee: Smiths Medical ASD, Inc.Inventors: Mark Faust, James Marrs, Steve Cote

Patent number: 7686787Abstract: A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.Type: GrantFiled: August 23, 2005Date of Patent: March 30, 2010Assignee: Medtronic Minimed, Inc.Inventors: Sheldon B. Moberg, Ian B. Hanson, Paul S. Cheney, II

Publication number: 20090216195Abstract: A penetrating instrument and method for piercing a desired tough or elastic tissue to a controlled and predetermined depth so as to avert any danger of damaging organs or tissues more deeply disposed. The instrument may comprise an introducer needle capable of independently penetrating bodily tissue and having a central hollow channel wherein a piercing needle is axially movable therein. The piercing needle may comprise a distal tip that is preferably fully disposed within the central hollow channel when the piercing needle is in a retracted position, but the piercing needle is capable of being deployed a predetermined distance beyond the distal end of the central hollow channel when disposed in an extended/piercing position. The introducer needle may be advanced through tissue until selected, problematic, or tough tissue is encountered. Subsequently, the piercing needle may be deployed and retracted, as necessary, to facilitate advancement of the instrument through the specific tissue.Type: ApplicationFiled: February 27, 2009Publication date: August 27, 2009Inventor: Ralph Zipper
