Method and apparatus for fine adjustment of a percutaneous valve structure
The invention provides a device for fine adjustment of a prosthetic valve device and a method of adjusting the position of a prosthetic valve after implantation. The adjustment mechanism includes complementary structures on a valve member and device frame that cooperate to provide relative axial and/or angular motion between the valve member and device frame (and thus the native vessel). The adjustment mechanism of the invention may also include a means for selectively maintaining the relative position of the valve member and device frame. The device and method are particularly applicable for use with a modular prosthetic valve device that is assembled in the body lumen.
Insertion instrument for intervertebral implants
An insertion tool for positioning intervertebral spacers into disc spaces. The insertion tool has a proximal end and a distal end, a T-handle secured to the proximal end and a pair of alignment rails extending to the distal end. The insertion tool includes a handle secured to the proximal end of the guide rails, and a shaft that extends through the handle, whereby the shaft has a threaded portion that extends to the T-handle. The insertion tool also includes a blocker that is secured to the distal end of the shaft. The blocker includes stop arms that guide the blocker through the guide rails and toward the distal end of the shaft. The blocker may be provided in a plurality of different sizes corresponding to the sizes of the implants to be inserted into a disc space. A lock is provided for locking the implant to the shaft.
Method of treating urinary incontinence
A method of treating urinary incontinence includes implanting the urethral support into a patient, where the urethral support has a first anchor attached to a first end of a non-porous sling and a second anchor attached to the non-porous sling. The method includes moving an adjustment device through a channel formed in one of the anchors from a first position that locates the adjustment device between the anchor and the non-porous sling to a second position that locates the anchor between the adjustment device and the non-porous sling.
Expandable Implant
An intervertebral implant includes a frame including an end member and an intermediate member pivotally coupled to the end member about a first pivot axis. The intervertebral implant includes a first vertebral contact member pivotally coupled to the frame about a second pivot axis that is substantially perpendicular to the first pivot axis, and a second vertebral contact member coupled to the frame. The frame is configured such that pivoting the intermediate member with respect to the end member about the first pivot axis changes both a width between the first vertebral contact member and the second vertebral contact member with respect to a direction that is substantially parallel to the second pivot axis, and changes a height between the first vertebral contact member and the second vertebral contact member with respect to a direction that is substantially parallel to the first pivot axis.
Method for deploying a prosthetic heart valve
A method for deploying an expandable prosthetic heart valve in a patient includes introducing a guidewire into a patient and advancing the guidewire through a vasculature of a patient to a deployment site. A distal end portion of a delivery apparatus and the prosthetic heart valve mounted in a radially compressed configuration along the distal end portion are advanced over the guidewire. The prosthetic heart valve is positioned at the deployment site. A screw mechanism is rotated, which exerts an axially directed onto the prosthetic heart valve, causing the prosthetic heart valve to radially expand from the radially compressed configuration to a radially expanded configuration.
Balloon Expandable Transcatheter Valve Delivery System
A prosthetic heart valve delivery system may include a handle, a delivery catheter with an inflatable balloon at a distal end thereof, and a prosthetic heart valve. An axial adjustment actuator may be positioned on the handle for translating the prosthetic heart valve distally or proximally relative to the handle when the prosthetic heart valve is collapsed onto the balloon. A commissure alignment actuator may be positioned on the handle for rotating the prosthetic heart valve about its central longitudinal axis when the prosthetic heart valve is collapsed onto the balloon. The axial adjustment and the commissure alignment actuators may be independently actuated, so that actuation of the axial adjustment actuator does not rotate the prosthetic heart valve, and actuation of the commissure alignment actuator does not translate the prosthetic heart valve.
METHOD FOR DEPLOYING A PROSTHETIC HEART VALVE
A method for deploying an expandable prosthetic heart valve in a patient includes introducing a guidewire into a patient and advancing the guidewire through a vasculature of a patient to a deployment site. A distal end portion of a delivery apparatus and the prosthetic heart valve mounted in a radially compressed configuration on an expandable member of the distal end portion are advanced over the guidewire. The prosthetic heart valve is positioned at the deployment site. The expandable member is radially expanded, causing the prosthetic heart valve to radially expand to a radially expanded configuration. The prosthetic heart valve comprises an expandable metal frame and one or more leaflets attached to the frame, wherein the frame comprises a plurality of struts arranged to form two circumferentially extending rows of hexagonal shaped cells.
Expandable intervertebral interbody implants
Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion implant may include an upper endplate and a lower endplate configured to engage adjacent vertebrae, an expansion gear configured to adjust a height of the upper endplate, a locking collar configured to attach to an inserter instrument at multiple orientations for a desired surgical approach, and an actuation ram configured to lock, unlock, or change insertion orientation of the locking collar. The expandable fusion device is attachable to the inserter instrument to reorient the locking collar and expand the upper endplate.
Prosthesis for inguinal hernia
The present invention relates to a prosthesis (1) for the repair of an inguinal hernia, which prosthesis (1) is intended to be implanted by a posterior or open laparoscopic route and comprises: an openworked textile (2) made of biocompatible material, comprising a first face (2a) intended to be placed facing the biological tissues of the inguinal region, and a second face (2b) arranged opposite said first face and intended to be placed facing the peritoneum, said first face being provided with fastening means that are able to fix said textile in said biological tissues of the inguinal region, characterized in that at least a part of said second face (2b) is covered with a non-porous coating (7) composed of a material that is hydrosoluble at 37 C. and non-hydrosoluble at 25 C. The invention also relates to a method for producing such a prosthesis.
Adjustable heart valve implant
Systems and methods are provided for repairing a heart valve, such as a mitral, tricuspid or aortic valve, using an adjustable and removable implant that can be delivered to the heart through the apex in a simplified and non-invasive manner. The implant can include a prosthetic valve portion coupled to a proximal end of a shaft, and an anchor portion coupled to a distal end of the shaft. The prosthetic valve can be suspended within an opening of the heart valve while the anchor portion is affixed to the apex of the heart. When the implant is deployed, a distance between the prosthetic valve portion and the anchor portion can be adjusted, and/or the implant or a portion thereof can be rotated to thereby change the position of the prosthetic valve within the heart valve. This can allow correcting for post-implantation movements of the implant to mitigate potential complications.
