Patent number: 8795230Abstract: An infusion set has a retraction dial that can be removably assembled with the infusion set and access a threaded needle hub contained therein such that the dial can be used to advance or retract a needle hub and an inserted needle to a more precisely controlled insertion depth to deliver insulin or other medicament intradermally (i.e. to the upper 3 mm of skin surface). Position of the inserted needle can be maintained by providing a separated and isolated needle hub, main base and main hub of the infusion set that can isolate the inserted needle from external forces such that the needle can be maintained at a depth to deliver content to the upper 3 mm of skin surface during normal use.Type: GrantFiled: November 22, 2011Date of Patent: August 5, 2014Assignee: Becton, Dickinson and CompanyInventors: Ryan Schoonmaker, Cole Constantineau, Michel Bruehwiler

Patent number: 8784383Abstract: An infusion set has a partially integrated ballistic inserter that can insert a needle at a controlled rate of speed to a depth to deliver content to the upper 3 mm of skin surface, and a skin-securing adhesive layer to secure the skin surface at the insertion site such that the inserter that can insert a needle with a reduced risk of tenting of the skin surface. A removable turnkey or pushable handle can be provided to release a driving spring of the ballistic inserter to insert a needle at a controlled rate of speed, of 3.3 ft/sec. (1.0 m/sec.) up to and including those greater than 10 ft/sec. (3.0 m/sec.), then release from the set for disposal. The infusion set can further include an extendable interface ring that retracts when the inserter is removed from the infusion set.Type: GrantFiled: November 22, 2011Date of Patent: July 22, 2014Assignee: Becton, Dickinson and CompanyInventors: Russell S. Cole, Christopher J. Kadamus, Stephen J. Irwin, Serge Roux, Eric Bené

Publication number: 20140200549Abstract: The present invention provides an improved intravenous (IV) catheter that enables a hands free means of preventing backflow of blood. The disclosed device incorporates a flow back inhibitor that includes leaflets radially layered upon one another in a conical form. In open mode the leaflets allow fluid flow and in closed mode the leaflets inhibit fluid flow. The device is attachable to a patient by means of an attachment component.Type: ApplicationFiled: January 19, 2012Publication date: July 17, 2014Inventor: Matthew W. Norkunas

Patent number: 8771230Abstract: An integrated vascular delivery system and method of use, the system including: a frame having a catheter hub that provides a first anchoring point on the patient and receives a catheter insertable in the patient to transfer fluid at an insertion site, a stabilization hub that provides a second anchoring point on the patient, at least one lateral member extending between the catheter and stabilization hubs, and a fluidic channel. The frame operates in a folded configuration in which the hubs are coupleable and an unfolded configuration in which the anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter. In some embodiments, the system further includes a septum that helps prevent fluid leakage from the catheter hub, or a needle shield that covers the distal end of a needle used during catheter insertion.Type: GrantFiled: May 19, 2011Date of Patent: July 8, 2014Assignee: Tangent Medical Technologies, LLCInventors: Steven B. White, Adrienne Rose Harris, Elyse Kemmerer, Nathan Farrell, Ronald Dean Duis, Henry J. H. Brown

Patent number: 8747360Abstract: Intravenous catheter devices are provided which may include one or more adhesive portions which are positioned and configured to temporarily maintain a position of a catheter assembly following catheterization. A release liner covering and protecting the adhesive portions may be automatically removed to reveal the adhesive upon withdrawal of an introducer needle of the catheter assembly. The adhesive may be configured such that a clinician may insert the catheter assembly into the patient, adjust the catheter adapter of the catheter assembly to a desired position, withdraw the introducer needle, thereby removing a protective, non-adhesive release liner from the adhesive of the positioned catheter assembly, thereby temporarily fixing the position of the catheter assembly at the desired position by contacting the exposed adhesive to the skin of the patient.Type: GrantFiled: December 5, 2012Date of Patent: June 10, 2014Assignee: Becton, Dickinston and CompanyInventors: Bart D. Peterson, Marcel A. Souza, Darin L. Peterson, Azhar J. Khan

Publication number: 20140148782Abstract: An apparatus and corresponding method for providing convection enhanced delivery of bioactive agent to a tissue site. The apparatus involves the use of semipermeable membranes, typically in the form of one or more hollow fibers, together with a source and conduit of solution containing the bioactive agent to be delivered. The use of hollow fiber technology provides an optimal combination of features, including delivery kinetics and distribution, as compared to conventional (e.g., standard needle) type delivery devices.Type: ApplicationFiled: May 27, 2011Publication date: May 29, 2014Applicant: TWIN STAR MEDICAL, INC.Inventors: Rick M. Odland, Bradford G. Staehle, Scott R. Wilson, Michael R. Wilson

Publication number: 20140148786Abstract: Devices (11, 111) for providing temporary access to the ventricle of the heart and then closing such an access passage when the operation demanding such access has been completed. These devices include an anchor (13, 113) with a wire spiral (19, 119) for implantation in the tissue wall of the heart and a handle (15, 115) detachably connected to the anchor. The handle provides an axial passageway in which a hollow needle (27, 127) is slidably and stably received. With the anchor in juxtaposition with the apex of the heart, the pointed end of the hollow needle is inserted into the ventricle, and its presence traversing the wall of the heart provides a stable axis about which the wire spiral (19, 119) can be rotated to seat the anchor in precise circumscribing fashion about the hollow needle (27, 127).Type: ApplicationFiled: January 30, 2014Publication date: May 29, 2014Inventor: Simcha Milo

Patent number: 8734397Abstract: An improved system and method for placing implantable medical devices (IMDs) such as leads within the coronary sinus and branch veins is disclosed. In one embodiment, a slittable delivery sheath and a method of using the sheath are provided. The sheath includes a slittable hub, and a substantially straight body defining an inner lumen. The body comprises a shaft section and a distal section that is distal to, and softer than, the shaft section. A slittable braid extends adjacent to at least a portion of one of the shaft section and the distal section. In one embodiment of the invention, the sheath further includes a transition section that is distal to the shaft section, and proximal to the distal section. The transition section is softer than the shaft section, but stiffer than the distal section.Type: GrantFiled: January 22, 2009Date of Patent: May 27, 2014Assignee: Medtronic, Inc.Inventors: Stanten C.
