Publication number: 20180008413Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.Type: ApplicationFiled: August 28, 2017Publication date: January 11, 2018Inventors: Hanson S. Gifford, III, James I. Fann, John Morriss, Mark Deem, Jeffry J. Grainger

Publication number: 20170071594Abstract: Various devices, systems and methods for knotless suturing of tissue are disclosed. These devices allow sutures to be anchored to bone, and more specifically provide a suture anchor which eliminates the need for knotting the suture. Thus, damaged tissue may be re-attached to a substrate tissue. The anchors have a minimum of moving parts may be suited to being a single molded polymer construction. The anchors will find particular utility in hip and shoulder arthroscopy, e.g. labral re-attachment and similar procedures.Type: ApplicationFiled: November 28, 2016Publication date: March 16, 2017Inventors: Michael Hendricksen, Mark Hirotsuka, Mark Deem, Jeffry J.

Publication number: 20150335429Abstract: Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having a first portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a valve support coupled to a second portion of the anchoring member, configured to support a prosthetic valve and having a cross-sectional shape. In some embodiments, the first portion of the anchoring member is mechanically isolated from the valve support such that the cross-sectional shape of the valve support remains sufficiently stable that the prosthetic valve remains competent when the anchoring member is deformed in the non-circular shape.Type: ApplicationFiled: August 7, 2015Publication date: November 26, 2015Inventors: John Morriss, Hanson Gifford, III, James I.

Patent number: 8986362Abstract: Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The prosthesis delivery devices may carry multiple prostheses and include deployment mechanisms for delivery of a selectable number of prostheses. Control mechanisms are provided in the prosthesis delivery devices that control either or both of the axial and rotational positions of the prostheses during deployment. This enables the deployment of multiple prostheses at a target site with precision and predictability, eliminating excessive spacing or overlap between prostheses. In particular embodiments, the prostheses of the invention are deployed in stenotic lesions in coronary or peripheral arteries, or in other vascular locations.Type: GrantFiled: May 22, 2009Date of Patent: March 24, 2015Assignee: J.W.

Patent number: 8460358Abstract: Wire-guided interventional devices and methods are provided which enable faster and easier catheter exchanges. The interventional devices include a catheter shaft and a guidewire tube wherein the catheter shaft and the guidewire tube each have a length sufficient to extend to the vascular penetration when the interventional device is positioned at the treatment site. In some embodiments, a collar is disposed around the catheter shaft and guidewire tube that automatically inserts or removes the guidewire from the guidewire tube or automatically collapses or extends the guidewire tube as the catheter is introduced or withdrawn.Type: GrantFiled: December 7, 2007Date of Patent: June 11, 2013Assignee: J.W.

Patent number: 8080048Abstract: Apparatus and methods for delivering stents to bifurcated vessels involve delivering a first stent in a main branch of a vessel using a stent delivery catheter and delivering a second stent in a side branch of the vessel, without removing the stent delivery catheter from the patient. In various embodiments, multiple stents may be placed in either or both of the main and side branches. In some embodiments, stents in main and side branches are separate and do not touch, while in other embodiments a side branch stent may extend through a sidewall opening in a main branch stent. Stent length may optionally be adjusted in situ, and some embodiments provide for predilatation of one or more lesions.Type: GrantFiled: March 30, 2004Date of Patent: December 20, 2011Assignee: Xtent, Inc.Inventors: Bernard Andreas, Jeffry J.

Patent number: 7918881Abstract: A stent deployment system includes a catheter shaft, an expandable member mounted to the catheter shaft, and one or more stents or stent segments slidably positioned on the expandable member. The stent deployment system is adapted for deployment of stents or stent segments in very long lesions and in tapered and curved vessels. The stent deployment system facilitates slidable movement of a stent in a distal direction relative to the expandable member while inhibiting slidable movement in a proximal direction relative to the expandable member.Type: GrantFiled: October 5, 2006Date of Patent: April 5, 2011Assignee: Xtent, Inc.Inventors: Bernard Andreas, David W.

Patent number: 7553324Abstract: Stent delivery devices and methods include multiple stents or stent segments mounted at fixed positions on an expandable member of the stent delivery catheter. One or more of the fixed-position stents may be selectively deployed in a body lumen such as a blood vessel by positioning one or more sheaths to constrain some stents while exposing other for deployment. Some embodiments include two axially movable sheaths for serially deploying stents while containing a portion of the expandable balloon from which stents have been deployed. Other embodiments include inner and outer balloon shafts to allow the balloon to be retracted into the delivery catheter as stents are deployed. Devices and methods of the invention provide enhanced serial deployment of multiple stents or stent segments while reducing the risk of damage to an expandable deployment member.Type: GrantFiled: October 14, 2003Date of Patent: June 30, 2009Assignee: Xtent, Inc.Inventors: Bernard Andreas, Jeffry J.
