Patent number: 8317751Abstract: An injection device (110) is provided which includes a syringe (122) having a discharge nozzle (118). The syringe is movable between a retracted position in which the discharge nozzle is contained within the housing and an extended position in which the discharge nozzle extends from the housing. A trigger (114) is activatable to allow the contents of the syringe to be discharged through the discharge nozzle. There is also a releasable locking mechanism (116) which, when engaged, prevents the trigger from moving into an active position. The trigger includes a first portion (150) having a cut-out (152) which extends from a first end of the trigger in a direction substantially parallel to the first axis (101). The releasable locking mechanism includes a protrusion (154) along a second axis (181) for communicating with the first portion of the trigger when the releasable locking mechanism is engaged and for communicating with the cut-out when the releasable locking mechanism is disengaged.Type: GrantFiled: March 21, 2006Date of Patent: November 27, 2012Assignee: Cilag GmbH InternationalInventors: Rosemary Louise Habeshaw, Jonathan Hogwood

Patent number: 8298171Abstract: After pressing a part of the exterior of a body of an administration instrument against a body region of a patient to which a drug solution is to be administered, an injection needle that is housed in the instrument body is automatically protruded from the body to insert the needle into the body region, and further, the injection needle being inserted into the body region is automatically housed in the instrument body to remove the needle from the body region. Thereby, the pain of the patient during needle insertion and needle removal is reduced, and administration at a constant speed is possible during injection of the drug solution. Furthermore, even when two kinds of drug solutions or a dissolving and mixing type drug solution are/is used, mixing can be easily and reliably carried out.Type: GrantFiled: July 2, 2003Date of Patent: October 30, 2012Assignee: Panasonic CorporationInventors: Tokumi Ishikawa, Tokumi Baba

Patent number: 8052645Abstract: An auto-injector for injecting a fluid medicament into a patient from a pre-filled syringe requires a disposable cassette that is selectively engageable with the reusable injector. The syringe is latched onto the cassette, and the cassette is then engaged with the injector. Activation of the injector causes a first motor to move the syringe so its needle is extended from a concealed position inside the cassette for injection of the medicament. A second motor on the injector is then activated to expel fluid medicament from the syringe. Then, the first motor is again activated to withdraw the syringe into the cassette for disposal of the cassette/syringe after an injection.Type: GrantFiled: July 23, 2008Date of Patent: November 8, 2011Assignee: Avant Medical Corp.Inventors: John B. Slate, Richard J. Koerner, Corey M. Magers, Michael W. Burk

Patent number: 7985197Abstract: A therapeutic-substance carrying/administering appliance includes a cylindrical outer sheath; a slide member installed in the cylindrical outer sheath to be slidable therein; and a sheet supporting member, connected to a distal end of the slide member and made of a resilient material, for supporting a sheet-shaped therapeutic substance. The sheet supporting member is held in a flat unrolled shape in a free state in which the sheet supporting member projects outwardly from a distal end of the cylindrical outer sheath. When the sheet supporting member is in the free state, sliding the slide member in a retracting direction causes the sheet supporting member to contact the distal end of the cylindrical outer sheath, and subsequently further moving the slide member in the retracting direction causes the sheet supporting member to be retracted into the cylindrical outer sheath while being deformed into a tubular shape.Type: GrantFiled: May 19, 2008Date of Patent: July 26, 2011Assignees: Hoya Corporation, Tokyo Women's Medical UniversityInventors: Masanori Maeda, Hidenori Takushima, Teruo Okano, Masayuki Yamato, Hiroshi Iseki, Ryoichi Nakamura, Takamasa Onuki, Masato Kanzaki, Takashi Suzuki, Shigeru Nagai

Patent number: 7985206Abstract: A catheter anchoring assembly includes a permeable adhesive strip, a platform for securing the catheter, and a flowable adhesive layer. The flowable adhesive layer adhesively secures the platform to the adhesive strip. The flowable adhesive is applied to one side of the strip with a skin-contacting adhesive on the opposite side of the strip. The flowable adhesive layer and strip are configured so that the flowable adhesive is spaced from the skin-contacting adhesive or, at the very least, is prevented from penetrating the skin-contacting adhesive. The flowable adhesive layer and strip also permit the assembly to be very flexible and, thus, comfortable for a patient to wear.Type: GrantFiled: August 30, 2010Date of Patent: July 26, 2011Assignee: Venetec International, Inc.Inventors: W.

Patent number: 7985202Abstract: An infusion device includes a pump forming front and rear chambers for receiving medicaments therein. The medicaments supplied from the two chambers are respectively transmitted into an elastic reservoir forming first and second lumens through first and second passageways. Then, the medicaments are infused into a person through a catheter which defines one passageway toward the human body. The first passageway is in fluid communication with the front chamber and second lumen. The second passageway is in fluid communication with the rear chamber, the first lumen, and the second lumen. By making the diameter of a second hole which connects the first lumen and second lumen smaller than a first hole which connects the first passageway and the first lumen, the medicament from the second chamber can be infused into patient with a low concentration.Type: GrantFiled: October 11, 2010Date of Patent: July 26, 2011Inventors: Nan Li, Shuqun Cheng, Hao Li

Patent number: 7914496Abstract: A ribbed seal for use in endoscopic surgery is intended to be incorporated into a cannula assembly to limit the escape of insufflation gasses from a body cavity by forming a fluid-tight seal around an instrument inserted through the cannula assembly. The ribbed seal includes a relatively flat, disk shaped elastomeric overmold portion having a central aperture sized slightly smaller than the instrument such that the aperture must expand to accommodate the instrument. Molded together with the elastomeric overmold is an array of slender ribs disposed about the aperture. The ribs are designed to be relatively flexible under lateral loads. This allows the seal to bend easily as the surgical instrument is inserted through the aperture thereby maintaining a low insertion and glide force. On the other hand, the ribs are designed to be relatively rigid when loaded axially. This rigidity provides robust radial support for the instrument inserted through the center of the array of ribs.Type: GrantFiled: May 21, 2008Date of Patent: March 29, 2011Assignee: Tyco Healthcare Group LPInventors: Oivind Brockmeier, Jared Alden Judson, Kenneth Allen Focht
