A radiopaque balloon with a composite wall having a radiopaque adhesive affixing inner and outer layers of the balloon. The radiopaque adhesive provides a radiographic image of the balloon wall with or without the use of radiopaque contract media to inflate the balloon. A radiographically fainter image is provided as the balloon is inflated with well-defined edges of a balloon image, and the total radiopacity of the balloon does not change as the balloon is inflated. Also, a method of imaging a balloon wall and a method of imaging a radiopaque adhesive between two layers of a balloon wall are provided.

Apparatus and methods are provided for treating patients exhibiting symptoms of hypertension, isolated systolic hypertension, heart failure with preserved ejection fraction, May-Thuner Syndrome or dyspnea by diagnosing and reducing narrowing of a patient's iliac vein caused by extrinsic localized compression using a stent having circumferential differential radial stiffness and delivery catheter for aligning and deploying such stents.

A catheter based balloon enabled prosthetic heart valve delivery device is provided. The balloon enabled delivery device is configured to deploy a prosthetic heart valve through inflation. The balloon enabled delivery device is further configured to reduce or prevent migration of the prosthetic heart valve during deployment. Migration is prevented through a combination of balanced inflation of the balloon, inflation fluid flow balancing structures, retention rings, retention covers, and balloon surface treatments.

Disclosed is an implantable device with enhanced drug delivery area, wherein a pre-crimped stent assembly mounted on a balloon further comprises a homogenous coating of drug and associated polymeric matrix resulting in the formation of a circumferential cylindrical film formation, upon expansion of the balloon. The cylindrical film formation by the drug delivery medical devices enables maximum coverage area of the vascular lumen area, thereby preventing any untreated area within a lumen.

A system for delivering a surgical staple can include various components. The system may include an elongate body with a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end. A sheath can move relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of a distal-most distal delivery platform to a second position in which the distal end of the sheath is disposed proximally of at least one delivery platform. A plurality of intravascular tacks can be within the system with each disposed about a corresponding delivery platform.

Devices, systems, and methods for implanting a patient-specific prosthesis at a treatment site in a patient are disclosed herein. In some embodiments, a patient-specific prosthesis includes a tubular graft and a coupling member. A fenestration can be disposed in the tubular graft, the fenestration corresponding to a predicted branch blood vessel location. The coupling member can be disposed about the fenestration. The coupling member can include a coil configured to expand from a first configuration to a second configuration in response to the application of an expanding force. The coil can be configured to contract to a third configuration upon removal of the expanding force.

Systems and devices for crimping a medical device and associated methods are disclosed herein. A crimping device configured in accordance with embodiments of the present technology can include, for example, a frame including a stationary plate, a movable member, and a plurality of blades arranged to form a channel and each including a pin that projects through a slot on the movable member and a corresponding slot on the stationary plate. The crimping device can be actuated to move the movable member relative to the stationary plate to drive the pins along paths defined by the slots to thereby drive the blades radially inward to crimp a medical device positioned within the channel.

The invention discloses a connection release structure and a system, wherein the connection release structure is configured for connecting a release object and is arranged on a loading sheath tube, and comprises a connection fixing system and an unlocking sleeve system; the connection fixing system comprises a hook structure, the unlocking sleeve system comprises an unlocking sleeve, the connection fixing structure and the unlocking sleeve are movably connected with the loading sheath tube, the connection fixing structure is configured for being connected with the release object, and the unlocking sleeve is configured for locking the connection fixing structure and the release. The connection release structure and the connection fixing system provided by the invention can accurately control the stability and coaxiality of the valve stent in the release process, effectively adjust the position of the valve stent in the implantation process or completely retract the valve stent so as to ensure that the valve has a good working state after being implanted.

The present disclosure describes implantable medical devices comprising covers, such as a balloon cover. Such devices can comprise a first layer of a porous polymeric material, such as ePTFE, surrounded by layers of a porous polymeric material having an imbibed elastomer, such as polyurethane. The cover can be used to assist in deployment of an expandable implant, such as a stent-graft, within the body of the patient.

A radiopaque balloon with a composite wall having a radiopaque adhesive affixing inner and outer layers of the balloon. The radiopaque adhesive provides a radiographic image of the balloon wall with or without the use of a radiopaque contrast media to inflate the balloon. A radiographically fainter image is provided as the balloon is inflated with well-defined edges of a balloon image, and the total radiopacity of the balloon does not change as the balloon is inflated. Also, a method of imaging a balloon wall and a method of imaging a radiopaque adhesive between two layers of a balloon wall are provided.
