A method of braiding a stent includes braiding a number of elongate filaments around a mandrel using tensioned braiding carriers without spooling the filaments to the tensioned braiding carriers to form a braided stent having atraumatic ends.

A stent configured to change in length while maintaining a constant inner diameter is disclosed. The stent includes an elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with rungs extending circumferentially between adjacent twisted knit stitches, wherein each twisted knit stitch is interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The tubular member is configured to be stretched from a first length to a second length while in a radially expanded configuration without substantially changing the inner and/or outer diameter of the tubular member.

A braided vaso-occlusive member formed out of first plurality of filaments interwoven with a second plurality of filaments, wherein filaments of the first plurality are helically wound in a first rotational direction along an elongate axis of the braided member, and filaments of the second plurality are wound in a second rotational direction opposite the first rotational direction, such that filaments of the first plurality cross over and/or under filaments of the second plurality at each of a plurality cross-over locations axially spaced along the elongate axis of the braided member, wherein at each cross-over location, the filaments of the first plurality cross over at least two consecutive filaments of the second plurality, then cross under only a single filament of the second plurality, and then cross over at least two additional consecutive filaments of the second plurality.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

The invention relates to a method for producing a vascular implant. The method comprises: obtaining vessel parameters; creating a computer-aided model of a vascular implant based on the obtained vessel parameters, wherein the vascular implant comprises one or more modules, each comprising at least one tubular liner body; selecting one or more structural elements of a respective module from the group consisting of: one or more diameter changes along at least one tubular liner body, one or more bifurcations, one or more branches, one or more recesses, one or more local reinforcements, and one or more iliac vessel grafts. The method further comprises: determining parameters relating to the one or more selected structural elements; integrating the structural elements into the computer-aided model according to the determined parameters; and producing the vascular implant based on the created computer-aided model. Furthermore, the invention relates to vascular implants produced by means of the method.

An integrally woven manifold is disclosed including a primary portion having a primary lumen disposed therein, a secondary portion branching off the primary portion, the secondary portion having a secondary lumen disposed therein in fluid communication with the primary lumen, and a first transitional portion connecting the primary portion to the secondary portion, the first transitional portion having a first aperture through which the secondary lumen fluidly communicates with the primary lumen. The primary portion has a first weave pattern, the secondary portion has at least a second weave pattern, and the first transitional portion is free of punctures, cuts, and bursts. A method for forming the integrally woven manifold is disclosed including continuously interlacing warp and weft to form the primary portion, intermittently interlacing the warp and the weft to form the secondary portion, and disengaging and reengaging the warp and the weft to form the first transitional portion.

A branched stent includes a main branch having a tubular main lumen and a side branch that branches off from the main branch. The main branch and the side branch are made from a strand-shaped starting material. The side branch is configurable between a first state in which the side branch lies within the main lumen and a second state in which the side lies outside the main lumen. In the second state, the side branch defines a tubular side branch fluidically connected to the main lumen. The side branch is formed at least in part of a shape-memory material.

The disclosure relates to a medical system for treating stenosis in intracranial blood vessels including a compressible and self-expandable implant for covering the stenosis, said implant having a lattice structure, at least some sections of which are provided with a cover made of an electrospun fabric, wherein the fabric has irregularly sized pores, and a balloon catheter for dilating the stenosis and/or introducing the implant into the blood vessel.

Stents generally can include a tubular structure having circumferentially positioned undulating wires that extend over a majority of a length of the stent such that the undulations oscillate circumferentially to define a circumference of the stent. The undulations can wrap over and under adjacent undulations to form an interwoven structure. Additionally, or alternatively, adjacent wires can be joined. Wires forming the stent can be cut from elastic tubing such that each wire has a three-dimensional shape.

A braided vaso-occlusive member formed out of first plurality of filaments interwoven with a second plurality of filaments, wherein filaments of the first plurality are helically wound in a first rotational direction along an elongate axis of the braided member, and filaments of the second plurality are wound in a second rotational direction opposite the first rotational direction, such that filaments of the first plurality cross over and/or under filaments of the second plurality at each of a plurality cross-over locations axially spaced along the elongate axis of the braided member, wherein at each cross-over location, the filaments of the first plurality cross over at least two consecutive filaments of the second plurality, then cross under only a single filament of the second plurality, and then cross over at least two additional consecutive filaments of the second plurality.
