Publication number: 20170340460Abstract: Systems and methods for the manufacture of an hourglass shaped stent-graft assembly comprising an hourglass shaped stent, graft layers, and an assembly mandrel having an hourglass shaped mandrel portion. Hourglass shaped stent may have superelastic and self-expanding properties. Hourglass shaped stent may be encapsulated using hourglass shaped mandrel assembly coupled to a dilatation mandrel used for depositing graft layers upon hourglass shaped mandrel assembly. Hourglass shaped mandrel assembly may have removably coupled conical portions. The stent-graft assembly may be compressed and heated to form a monolithic layer of biocompatible material. Encapsulated hourglass shaped stents may be used to treat subjects suffering from heart failure by implanting the encapsulated stent securely in the atrial septum to allow blood flow from the left atrium to the right atrium when blood pressure in the left atrium exceeds that on the right atrium.Type: ApplicationFiled: May 30, 2017Publication date: November 30, 2017Applicant: V-Wave Ltd.Inventors: Lior ROSEN, Neal EIGLER, Erez ROZENFELD, Nir NAE, Werner HAFELFINGER, Yeela SCOP

Patent number: 8029470Abstract: Systems and methods for penetrating a tissue membrane to gain access to a target site are disclosed. In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a stabilizer sheath having a side port, a shaped guiding catheter configured to exit the side port and a tissue penetration member disposed within and extendable from the distal end of the guide catheter. The tissue penetration member may be configured to penetrate tissue upon rotation and may be coupled to a distal portion of a torqueable shaft. In some embodiments, the stabilizer sheath and shaped guiding catheter may be moved relative to the patient's body structure and relative to each other so that a desired approach angle may be obtained for the tissue penetration member with respect to the target tissue.Type: GrantFiled: September 30, 2004Date of Patent: October 4, 2011Assignee: Pacesetter, Inc.Inventors: James S. Whiting, Neal L. Eigler, John L. Wardle, Werner Hafelfinger, Brian Mann

Patent number: 7967790Abstract: A hemostasis valve is disclosed herein. The hemostasis valve may include an inner bushing, a rotation sleeve, an elastomeric sleeve, and a biasing element. The rotation sleeve may extend about the inner bushing and be rotationally displaceable relative to the inner bushing. The elastomeric sleeve may include a first end operably coupled to the inner bushing, a second end operably coupled to the rotation sleeve, and an iris valve portion. Rotation of the rotation sleeve relative to the inner bushing may cause the iris valve to transition from an open state to a closed state. The biasing element may act between the rotation sleeve and inner bushing to bias the iris valve towards at least one of a closed state or an open state.Type: GrantFiled: September 1, 2009Date of Patent: June 28, 2011Assignee: Pacesetter, Inc.Inventors: James S. Whiting, Werner Hafelfinger, Neal L. Eigler, John L. Wardle

Publication number: 20110022057Abstract: A transfer guidewire assembly configured to manipulate an implanted elongate body includes a flexible elongate portion, such as a guidewire, and coupler. The flexible elongate body has a proximal end and a distal end attached to the coupler. The coupler can include a catheter and/or a handle. The handle can include a screw. The coupler is configured to be removably attached to the end of an implanted elongate body, for example, by forming an interference fit with the outside diameter of the implanted body. A method for transferring an end of an implanted medical component from first site to a second site within a patient, such as a pacemaker, defibrillator, and/or sensor lead, etc., includes inserting a guidewire into the body at the first site and externalizing the guidewire at the second site. A proximal portion of the implanted component near the first site and is attached to the guidewire.Type: ApplicationFiled: July 23, 2010Publication date: January 27, 2011Applicant: PACESETTER, INC.Inventors: Neal L.

Patent number: 7402899Abstract: A device and method for hermetically sealing a medical device is provided. In one aspect, a silicon device is coupled to a sensor, such as a pressure transducer, which benefits from having direct contact with its environment, which in many cases, is the human body. Thus, a method to hermetically seal the non-sensing portion of a silicon device while allowing the sensing portion (e.g. the pressure transducer) to have direct contact with the body is provided. In one aspect, a silicon chip, a gold preform and a metallic housing are each primed for sealing and are assembled. The assembly is then heated to react the gold preform to the silicon chip and to form a molten gold-silicon alloy in-situ to bind the metallic housing to the non-sensing portion of the silicon chip. In this way, the non-sensing portion of the silicon chip is hermetically sealed and protected from exposure, while still permitting exposure of the sensing portion to the environment.Type: GrantFiled: January 12, 2007Date of Patent: July 22, 2008Assignee: Pacesetter, Inc.Inventors: James S.
