Publication number: 20230330338Abstract: 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: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Inventors: John B. Slate, Richard J. Koerner, Corey M. Magers, Michael W. Burk

Patent number: 9925336Abstract: A system for injecting a fluid medicament into a patient includes a drive mechanism, and a cassette loaded with a pre-filled hypodermic syringe. When the cassette is loaded, the syringe is held firmly inside and the cassette can be selectively engaged with the drive mechanism. The drive mechanism has two motors. A first motor initially moves the hypodermic syringe from a position inside the cassette where its needle is concealed, to a position where the needle extends from the cassette for insertion into a patient for an injection. With the needle inserted, a second motor pushes the syringe stopper to expel a fluid medicament from the syringe. After an injection, the first motor withdraws the syringe back into concealment inside the cassette, to again firmly hold the syringe on the cassette. The cassette and syringe, in combination, can then be removed from the drive mechanism and discarded.Type: GrantFiled: April 24, 2012Date of Patent: March 27, 2018Assignee: AVANT MEDICAL CORP.Inventors: John B.

Patent number: 8162929Abstract: An applicator for cryoablating tissue to form linear (i.e. straight line and curvilinear) lesions in targeted tissue includes a fluid refrigerant delivery system having a source of a fluid refrigerant and a tubular cryoablation segment. Structurally, the segment has an open proximal end and a distal end, and is formed with a lumen. Also, the segment is formed with at least one distal port and at least one proximal port, with each port connected in fluid communication with the segment's lumen. The proximal end of the tubular segment is operably connected in fluid communication with the source of fluid refrigerant. For the system, the ports can be selectively sized to outflow liquid refrigerant through the distal and proximal ports at a substantially same mass flow rate.Type: GrantFiled: June 1, 2007Date of Patent: April 24, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: David J.

Patent number: 8092444Abstract: An articulation segment for a catheter includes a tube formed with a first plurality of axially aligned slits that are respectively oriented in planes perpendicular to the axis, with each slit extending azimuthally in an arc partway around the axis. The tube is also formed with a second plurality of similarly formed slits that are axially offset and diametrically opposed relative to the slits of the first plurality to allow for a bending of the catheter in a plurality of different planes. In a particular embodiment, the slits are arranged to allow the articulation segment to be reconfigured from a straight, substantially cylindrically shaped tube to a configuration in which a portion of the articulation segment is formed in the shape of a ring.Type: GrantFiled: December 18, 2009Date of Patent: January 10, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: David J.
