Method and system for patella tendon realignment
A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, and an anterior portion. The superior portion being configured to reside below a patellar tendon and to elevate and/or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes affixing the implant.
Method for performing surgical procedures using optical cutting guides
A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.
Protuberant aneurysm bridging device deployment method
An aneurysm bridging device can be placed in the neurovasculature of a patient by advancing the aneurysm bridging device in a small-diameter configuration a delivery catheter to a target region within the neurovasculature and securing the distal region of the aneurysm bridging device to the neurovasculature. While the distal region of the aneurysm bridging device is secured to the neurovasculature, the proximal region of the aneurysm bridging device can be advanced to permit the aneurysm bridging device to expand from the small-diameter configuration and to deform and twist in a central region of the aneurysm bridging device. The proximal region of the aneurysm bridging device can be secured within the neurovasculature to maintain the central region of the aneurysm bridging device in a deformed state.
Implants having high fatigue resistance, implant delivery systems, and methods of use
According to one aspect of the preset invention, a fatigue resistant stent includes a flexible tubular structure having an inside diameter, an outside diameter, and a sidewall therebetween and having apertures extending through the sidewall. According to other aspects of the invention, processes for making a fatigue resistant stent are disclosed. According to further aspects of the invention, delivery systems for a fatigue resistant stent and methods of use are provided.
HEART VALVE SEALING DEVICES AND DELIVERY DEVICES THEREFOR
Example systems and valve repair devices for repairing a native valve of a patient includes a plurality of paddle portions. The plurality of paddle portions are moveable between an open position and a closed position by moving a cap with respect to a collar. A plurality of paddle frames are connected to the cap and to the paddle portions. A width of the plurality of paddle frames is adjustable during an implantation procedure of the valve repair device.
Textured surfaces for implants
An implant material having an implant surface comprising a plurality of tissue-contacting members arranged in a regular or irregular two-dimensional array, each tissue-contacting member having a convex curved tissue-contacting surface. Methods of preparing and using such implant materials.
Stent with Enhanced Low Crimping Profile
The invention is directed to an endovascular device having an undulating pattern of struts and loops. In a first aspect of the invention, the endovascular device comprises a main stent component having a tubular shape and a first end and a second end, said device having a first radiopaque marker and a second radiopaque marker each having a shape with at least two distinct profiles when viewed from different angles, said markers positioned on the main stent component to be offset by less than 180 degrees relative to the other. In a second aspect, the endovascular device has a particular stent pattern, where at least one strut has a bend in the crimped profile for reducing the compressed diameter having the following features. The strut configuration comprises one or more bent sections facing in opposite convex and concave orientations, thereby creating a space or hollow for an oppositely aligned portion of the device to nestle therein as the device is compressed. The undulating pattern may be staggered such that adjacent loops within individual windings are axially offset with respect to a perpendicular axis perpendicular to the lengthwise direction. Adjacent windings may be interconnected in the longitudinal direction of the device by flexible connectors.
Modular multibranch stent assembly and method
The techniques of this disclosure generally relate to an assembly including a single branch stent device and a modular stent device configured to be coupled to the single branch stent device. The single branch stent device includes a main body and a branch coupling extending radially from the main body. The modular stent device includes a main body configured to be coupled inside of the main body of the single branch stent device, a bypass gate extending distally from a distal end of the main body of the modular stent device, and an artery leg extending distally from the distal end of the main body of the modular stent device.
Insertion and release system for implants
The invention relates to a device for the introduction of an implant (1) into blood vessels of the human body, said device comprising an implant (1), a pusher or insertion wire (14), and a tube-like sheathing (13), wherein the implant (1) is capable of being deformed inside a microcatheter in a manner that allows it to assume a shape of reduced diameter and, after omission of such external constraint exerted by the microcatheter, expand at the placement site and adapt to the blood vessel diameter, and wherein the implant (1) being provided at the proximal end with connection elements (6) attaching it to a retaining element (15) by means of which the implant (1) is coupled to the pusher wire (14), and wherein the retaining element (15) is provided with peripheral cutouts (16) into which the connecting elements (6) are fitted, with the tube-like sheathing (13) being drawn in a form-closed manner over the retaining element (15) with fitted connection elements (6) such that the connection elements (6) are secured within the cutouts (16) of the retaining element (15) and the implant (1) being released by the retraction of the tube-like sheathing (13) in proximal direction, with the outer diameter of the tube-like sheathing (13) varying between the proximal and the distal end. In this manner, high pliability is achieved in some sections of sheathing (13) which is conducive to maneuvering through narrow blood vessels, and, moreover, sufficient tensile strength is available for the purpose of releasing implant (1).
Methods and systems for establishing retrograde carotid arterial blood flow
Interventional procedures on the carotid arteries are performed through a transcervical access while retrograde blood flow is established from the internal carotid artery to a venous or external location. A system for use in accessing and treating a carotid artery includes an arterial access device, a shunt fluidly connected to the arterial access device, and a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. The flow control assembly includes one or more components that interact with the blood flow through the shunt.
