This disclosure relates to a heart valve with improved functionality and durability.

Heart valve mimicry

An endovascular treatment system includes a delivery sleeve that is insertable into an intravascular catheter. A therapeutic device is housed coaxially within the delivery sleeve and both are advanced within the catheter in combination. An advancement mechanism is connected to the therapeutic device to advance the therapeutic device out of the delivery sleeve and into a patient. The delivery sleeve includes a stop positioned on the proximal end. The stop contacts the proximal end of the catheter, limiting the distance the delivery sleeve is inserted into a catheter.

Sleeve for delivery of embolic coil

The disclosure relates to a heart valve with improved functionality and durability.

Disclosed herein are detachment mechanisms for vaso-occlusive devices that allow for rapid operator-controlled release of the vaso-occlusive device into the selected site. Also disclosed are vaso-occlusive assemblies comprising these detachment mechanisms and methods of using these detachment mechanisms and vaso-occlusive assemblies.

Detachment mechanisms for implantable devices

A medical device including a shaft having an elongated inner member and an elongated tubular reinforcing member disposed over at least a portion of the inner member. In some embodiments, at least a portion of the outer surface of the inner member is spaced from the inner surface of the reinforcing member, defining a space substantially free of any other structures of the device. In some embodiments, the shaft can include a tip structure disposed on a distal portion of the inner member. In some such embodiments, the reinforcing member has a distal end, and the tip structure is disposed on the distal portion of the inner member adjacent the distal end of the reinforcing member. Additionally, in some embodiments, the reinforcing member can include a plurality of apertures defined therein, for example, to enhance the flexibility or other such characteristics of all or portions of the reinforcing member.

Medical device

A device for delivering an implant to a vascular disorder of a patient includes a delivery pusher. A stationary blade may be coupled to the delivery pusher. The stationary blade may include a sharp and stationary cutting component for cutting through a suture coupling the implant to the delivery pusher and for thereby releasing the implant when placed in proximity to the vascular disorder. In some cases, the strength of a junction connecting the suture to the implant is equal to or greater than the tensile strength of the suture itself. Additionally, or alternatively, a detachment handle may be fixedly and permanently attached to the delivery pusher such that a user of the device need not couple the detachment handle to the delivery pusher. The detachment handle may include a user manipulable component for initiating a mechanical release of the implant when placed in proximity to the vascular disorder.

Implants, methods of manufacturing the same, and devices and methods for delivering the implants to a vascular disorder of a patient

An embolic microcoil can be formed into a complex shape for use in treating aneurysms and other vascular disorders. The microcoil features a distal portion including several loops that together comprise a substantially spherical shape, and an elongated proximal portion that is deployable within the distal portion. The distal portion can create a stable frame with adequate loop coverage across a neck of the aneurysm. The proximal portion can include a series of substantially omega-shaped loops, which can apply a force against the interior of the substantially spherical shaped distal portion, expanding it into apposition with additional portions of the aneurysm wall. Methods of treating vascular disorders and methods of manufacturing certain microcoils are also disclosed.

Embolic framing microcoils

Catheters such as guide catheters can be configured for delivery of devices to vasculature portions such as intracranial spaces while retaining a desired level of flexibility. A catheter having an elongate shaft can include removable support means that can provide column support to the elongate shaft. The elongate shaft can include anchoring means that releasably secure the removable support means. The catheter can be deployed within a patient's vasculature, followed by deploying the removable support means.

Guide catheter with removable support

Hypotubes such as micromachined hypotubes can include one or more tie layers appropriate for subsequent application of a hydrophilic coating. In particular, a medical device may include a micromachined hypotube having a level of flexibility and a tie layer disposed over the hypotube such that the medical device has a level of flexibility at least substantially equivalent to the level of flexibility of the hypotube.
