STENT INCLUDING AN EXPANDABLE MEMBER
Example medical stents are disclosed. An example stent includes a tubular framework including an inner surface, an outer surface and a lumen extending therethrough. Additionally, the stent includes a tissue ingrowth scaffold extending along a portion of the outer surface of the tubular framework, wherein the tissue ingrowth scaffold is spaced radially away from the outer surface of the tubular framework to define an expansion cavity therebetween and wherein the tissue ingrowth scaffold permits tissue ingrowth along a portion thereof. Further, the stent includes an expandable member positioned within at least a portion of the expansion cavity.
RETRIEVAL DEVICES FOR HEART VALVE SEALING DEVICES
A retrieval device for retrieving a previously implanted device from a native valve of a patient's heart includes one or more retrieval components. The retrieval components include one or more of a device securing member, a device actuation member, and a clasp capturing member. The securing member is configured to attach the retrieval device to the previously implanted device. The actuation member engages the previously implanted device to move the previously implanted device from a closed configuration to an open configuration. The clasp capturing member is configured to attach to a clasp of the previously implanted device.
Surgical devices and methods
An intravascular cutting device described herein uses high-pressure water, saline, or other fluid to cut tissue and other materials including but not limited to calcified tissue, stents, stent grafts, and other devices. In some embodiments, the cutting device includes a working end that has a nozzle with a hole to allow the release of a high-pressure fluid jet. Opposite of the nozzle is a catch plate or deflector anvil that prevents the fluid jet from cutting healthy tissue. The device user will place the item to be cut between the nozzle and catch plate and then advance the device along the item to be cut as the fluid jet is activated, thus cutting the object as it advances.
INTEGRATED STENT REPOSITIONING AND RETRIEVAL LOOP
A braided stent having an integral retrieval and/or repositioning loop includes a plurality of wires having first and second ends interbraided in a braided pattern to form a tubular stent having opposed atraumatic first and second open ends with each open end having a circumference; wherein said first and second wires ends are disposed at said second stent open end and said wires are looped at said second stent open end so that none of the first or second wires ends are exposed at the circumference of second stent open end; wherein at least of two of said wires are formed into a repositioning and/or retrieval loop having an elongated portion circumferentially disposed at said first opposed open end; and wherein said reposition and/or retrieval loop comprises two sections which run adjacent to each other prior to crossing to permit grabbing of both sections simultaneously by a practitioner.
Delivery of medical devices
A stent delivery system can include a core member, an introducer sheath, and a microcatheter. The core member can have a distal segment. The stent engagement member can have a generally tubular body positioned about the core member distal segment and can be rotatably coupled to the core member. The engagement member can include an inner layer that has a first durometer and an outer layer that has a second durometer less than the first durometer. The stent can extend along the core member distal segment such that an inner surface of the stent is engaged by the engagement member outer layer for facilitating rotation of the stent relative to the core member.
Method for retrieval of a medical device
Funnel-trap type devices are described that are made of shape-set (e.g., heatset) braid for delivery and/or retrieval of Inferior Vena Cava (IVC) filters or other medical devices. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated. Additional forming tooling, methods and device embodiment shapes are described herein.
Endograft delivery device assembly
An endovascular delivery device comprises an outer handle with a track; an inner handle moveable relative to the outer handle; a tip assembly slider mounted on the track; the tip assembly having a top cap and a retriever, the top cap comprising a mouth receiving a proximal portion of the endograft and closable by the retriever; a connector extending from the tip to the inner handle and including a distal portion slidably engaging the inner handle; a pusher catheter extending from the outer handle assembly; a guidewire catheter; a distal trigger wire operable to release the distal end of the endograft; a proximal trigger wire release slider mounted on the track and movable from an initial to a triggered position, wherein the tip assembly slider engages the trigger wire release slider to prevent distal movement until the trigger wire release slider is moved distally.
SYSTEMS AND METHODS FOR IMPLANTS AND DEPLOYMENT DEVICES
After a prolonged period in the body, an IVC filter can be substantially absorbed by the body. When this occurs, it can be very difficult and/or dangerous for the patient if the IVC filter is forcibly removed. Thus, it is desirable to have systems and methods for safely abandoning the removal procedure of the IVC filter. Example embodiments of an apparatus for safely abandoning the removal procedure of the IVC filter can include: a sleeve having a lumen and a first hole on a wall of the sleeve; a shaft slidably disposed within the lumen of the sleeve; a flexible distal extension comprising a braid structure with a first opening; and a first lasso encircling a portion of the first opening of the braid.
PLACING AND REMOVING SURGICAL STENTS
Systems and methods are configured for precise placement of surgical stents. A customized endoscopic system has a stent positioned between an inner cannula and the outer sleeve. The inner cannula has an integrated camera and illumination on its distal tip. The operator can make precise stent placements while viewing live video on an integrated display mounted on the hand piece. The stent can be removed using a specialized hook device. The system can have a single use portion that includes the cannula with imaging module, stent and outer sleeve. The re-usable portion can include the hand piece and display screen.
SEALABLE ENDOVASCULAR IMPLANTS AND METHODS FOR THEIR USE
A method of implanting a prosthetic implant includes advancing a prosthetic implant into a patient's vasculature with a delivery apparatus, the delivery apparatus comprising a catheter and a control lead, the catheter including a lumen extending therethrough, the control lead extending through the lumen of the catheter, the prosthetic implant comprising an implant body, a seal extending radially outwardly from the implant body, and a locking bar coupled to the implant body and releasably coupled to the control lead, the locking bar radially offset relative to the central longitudinal axis of the implant body. The method further includes rotating the control lead of the delivery apparatus in a first direction relative to the catheter such that the locking bar rotates in the first direction relative to the implant body and the implant body expands radially from a first radially compressed state to a first radially expanded state.
