A delivery cylinder for a prosthetic implant can include a first tubular portion and a second tubular portion. The second tubular portion has a plurality of strut members coupled to the first tubular portion that define a volume for containing the prosthetic implant in a radially compressed state. The strut members can include respective flex regions configured such that application of force to the strut members causes deformation of the flex regions and corresponding radially inward or outward movement of the strut members relative to a longitudinal axis of the delivery cylinder between an expanded configuration and a contracted configuration.

A retrieval device comprising a hook assembly and a capsule assembly. The hook assembly has an attachment feature at a first end. The capsule assembly includes a capsule, a capsule shaft, and a handle connected in series and defining an inner bore. The capsule has a first end defining an opening. The inner bore of the capsule assembly is configured to slidably receive the hook assembly. The handle has a central portion, a first extension portion attached to the capsule shaft, and a second extension portion with a hook assembly lock at a second end. The hook assembly lock is configured to lock the hook assembly to the second extension portion. The second extension portion is configured to pull the hook assembly relative to the capsule shaft, and the first extension portion is configured to push the capsule shaft relative to the hook assembly along the central longitudinal axis.

A percutaneous device including a temporary valve attached to a sheath, the sheath having an inverting section for delivery and removal thereof from a blood vessel. The sheath is inverted for delivery, housing the valve between inverted layers thereof. To deploy said valve, the sheath is everted to position the temporary valve on an outer surface thereof. The temporary valve and sheath are reversibly movable between inverted and deployed configurations. Upon eversion, the temporary valve assumes a radially expanded canopy shape having an outer diameter selected to contact the vessel wall and allow blood flow in only one direction. The temporary valve may be removed by releasing one end of the valve from the sheath, flattening the temporary valve along the longitudinal axis of the sheath. Also provided is a temporary valve system comprising a dilator for inverting and everting the sheath, said dilator being removably connected to the sheath.

An implantable artificial bronchus including a body having a proximal upper opening and a distal lower opening. The distal lower opening being in fluid communication with the proximal upper opening, and the body at least partially tapering along a length toward the distal lower opening. The body having a plurality of side openings configured to allow air to enter into and exit the implantable artificial bronchus through the body. A length of the body is greater than 4 times the size of a largest diameter of the body, and the diameter of the proximal upper opening is larger than a diameter of the distal lower opening.

A tool for removing non-visually, urinary tract stents placed within the urinary tract of a patient, comprising a distal end, a longitudinally-extending stem, and a handle. The distal end has a conical head with a groove for hooking a stent, stent string or similar stent configuration. The snare head may have a channel for advancing the tool through a urethra over a guide wire. The snare head has a narrow conical front end for dilating urethral strictures. The stem connects the snare head to the snare handle and is made to be flexible or bend on encountering resistance.

A delivery system for delivering and deploying stents with proximal and distal apices includes a guidewire catheter, a nose cone assembly, a proximal capture portion and a stent graft with proximal and distal stents. The nose cone assembly is at the distal end of the guidewire catheter and includes a nose cone and a distal capture portion. The proximal capture portion is proximal to the distal capture portion of the nose cone assembly. The proximal stent is releasably secured to the distal capture portion and the distal stent is releasably secured to the proximal capture portion. The stent graft can be deployed by releasing the proximal stent and the distal stent from proximal and distal capture portions of the delivery system.

An illustrative endoluminal implant having an elongated tubular member. The elongated tubular member having a stent and a retrieval suture interwoven with the stent. The retrieval suture including a first suture loop extending about a circumference of the stent and adjacent to a suture retrieval loop and a second suture loop extending about a circumference of the stent and longitudinally spaced from the first suture loop. The first and second suture loops coupled via one or more interconnecting segments. At least one of the first or second suture loops has an arc length of less than 270° of the circumference of the stent.

Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.

The described invention provides an endovascular device comprising a tube comprising a first end comprising a bifurcation and a second end comprising an opening. The bifurcation at the first end comprises a first branch and a second branch. The opening at the second end comprises a primary opening and a secondary opening. The first branch and the primary opening form a working lumen. The second branch and the secondary opening form a support lumen. The described invention further provides an endovascular device comprising a tube comprising a side-hole, a first segment comprising a primary opening and a second segment. The side-hole and the first segment form a working lumen. The second segment forms a support lumen.

Expandable elements having drug-delivery features and associated systems and methods are disclosed herein. In one embodiment, a drug-eluting stent includes a radially expandable cylindrical frame having a plurality of struts. The frame is transformable between a low-profile delivery state and an expanded deployed state. A plurality of drug-delivery features are carried by one of the struts and configured to deliver a drug to a treatment site within the patient or piercing through the tissue wall to break the constricting of the vessel wall inwardly. When the frame is in the expanded state within a body lumen of the patient, the drug-delivery features extend radially outwardly away from the strut and are configured to engage and, in some arrangements, pass through a wall of the body lumen.
