Disclosed are systems, methods, and devices for percutaneous retrieval of objects, such as endovascular devices, from an internal body space. The present inventions have vascular, non-vascular (gastrointestinal), and surgical (laproscopic) applications. The inventions include a a wire woven distal end that is formed from wires and includes a substantially cylindrical main body section comprising a leading end, a trailing end, and a middle portion extending between the leading end and the trailing end and defining a longitudinal axis of the main body section, and a flare defining a mouth of the wire woven distal end that projects circumferentially from the leading end of the main body section, wherein when at least a portion of the retrieval end is transitioned to a compressed state following capture of an object, the retrieval end exerts an inward force that at least partially collapses or compresses the object.

Systems and methods of adjusting the diameter of an endoluminal prosthesis that allows for controlled radial deployment of the endoluminal prosthesis and the ability to revise the positioning of the endoluminal prosthesis after unsheathing. The endoluminal prosthesis includes a stent graft having a tubular graft wall, a stent, a main strand, a proximal strand, and a distal strand.

A stent delivery device including an elongate shaft having a proximal region, a distal region and at least one lumen extending therein. The stent delivery device also includes a collapsible frame attached to the distal region of the elongate shaft. The collapsible frame includes a plurality of arms configured to surround a stent such that the plurality of arms define a stent containment region. The stent delivery device also includes an inner member extending within a least a portion of the stent containment region and an actuation member configured to actuate the plurality of arms of the collapsible frame from an expanded configuration to a collapsed configuration.

Medical devices and methods for making and using a medical device are disclosed. An example medical device may include a stent that comprises a first covered region formed of one or more interwoven filaments and a covering. The stent may also comprise a second uncovered region adjacent the first covered region. The second uncovered region may include a knitted filament. A first end of the knitted filament may be attached to the first covered region. The knitted filament is configured to be unraveled to remove both the first covered region and the second uncovered region of the stent while the first end of the knitted stent remains attached to the first covered region.

The invention provides a system (1) and method for manufacturing a stent. A spraying device (14) sprays a polymeric suspension (16) onto a mandrel (4). During spraying of the polymeric suspension (16) onto the mandrel (4), the mandrel (4) is manipulated by a micromanipulator (8) to produce a continuous coating on the mandrel (4) having a nonuniform thickness. The polymeric coating is allowed to cure on the mandrel (4) to form the stent, which is then removed from the mandrel (4). The method can comprise embedding a filament (2) in the polymeric coating and incorporating one or more drugs in the stent.

A stent delivery device for deploying a low column strength stent may include an inner member having a distal region and a stent receiving area disposed therein. A low column strength stent convertible between a compressed configuration and an expanded configuration may be disposed on the stent receiving area. The stent receiving area may include a soft durometer polymer configured to permit the low column strength stent to sink into the soft durometer polymer when the low column strength stent is in the compressed configuration. An outer member may be moveable between an extended position in which the outer member extends over the stent and a retracted position in which the outer member is proximal of the stent.

A catheter device (2) is provided for implanting an anchor (9) into body tissue to attach a line (14) to the body tissue. The catheter device (2) comprises: a housing section (4), (8) extending from a distal end of the catheter device (2) along the length of the catheter device (2) toward the proximal end of the catheter device, the housing section (4), (8) comprising a distal part (8) at the distal end of the catheter device (2) and a proximal part 4 located on the proximal side of the distal part (8). An anchor deployment mechanism (106), (110) is provided at the distal part (8) of the housing section (4), (8) for deployment of the anchor (9) for attachment of the anchor (9) to the body tissue. The anchor (9) is held in its stowed position by the anchor deployment mechanism (106, 110) in the distal part (8) prior to deployment, and the anchor (9) comprises a number of hooks (62) for engagement with the body tissue and having a folded position and an unfolded position, wherein the anchor (9) is made of an elastic material such that the hooks (62) can be elastically deformed into the folded position by application of a constraining force, and will return to the unfolded position when no constraining force is applied, and wherein the hooks (62) are held in the folded position whilst the anchor (9) is in the stowed position within the distal part (8). The distal part (8) of the housing (4), (8) has a non-circular shape (118), (117) for engagement with a corresponding non-circular form (28), (108) of the anchor (9) and/or the anchor deployment mechanism (106), (110), such that when the anchor (9) is held in the distal part (8) movement of the anchor (9) is restrained with respect to rotation of the anchor (9) about a longitudinal axis of the distal part (8) due to engagement between the non-circular shape (118), (117) and the non-circular form (28), (108).

A medical having a proximal and a distal end, that is preformed to assume a superimposed structure at an implantation site but can be made to take on a volume-reduced form making it possible to introduce it by means of a micro-catheter and a guide wire arranged at the proximal end, with the implant in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments. The implant has a tapering structure at its proximal end where the strings or filaments converge at a connection point.

A stent for insertion into an intracranial blood vessel of the cerebral venous sinus system includes a proximal end, a distal end, a body between the proximal end and the distal end, the body comprising a plurality of wires in a closed pattern, wherein the stent is configured for insertion into an intracranial blood vessel of the cerebral venous sinus system. The stent is further capable of being repositioned, retrieved/re-sheathed, and removed for more precise delivery.

A self-expanding braided stent includes at least a distal radial expansion ring added to a distal end of the stent body to increase a radial expansion force of the self-expanding braided stent in deployment of the stent, and to facilitate advancement of the stent through a delivery sheath by a core advancement wire. A proximal radial expansion ring is optionally added to a proximal end of the stent body to allow the stent to be recaptured following partial deployment by retraction of the core advancement wire, prior to full deployment of a proximal portion of the stent body.
