Abstract: An elongated medical device includes an elongated tubular element with a series of flexibility enhancing features along a length of the elongated tubular element. Each flexibility enhancing feature may include a series of cuts. The cuts of one flexibility enhancing feature may be offset relative to the cuts of a longitudinally adjacent flexibility enhancing feature. The flexibility enhancing features may be grouped into two or more interleaved sets, with each set of circumferential cuts being offset relative to the next set of circumferential cuts. Methods for manufacturing such elongated medical devices are also disclosed.

Abstract: An endovascular shunt implantation system includes a guide member configured for being deployed in an inferior petrosal sinus, and a delivery catheter movably coupled to the guide member, wherein a distal end of the delivery catheter includes a tissue penetrating element. A guard is disposed over the tissue penetrating element, the guard having an open distal end portion including an inner surface feature configured to deflect the tissue penetrating element away from the guide member when the tissue penetrating element is translated distally relative to the guard. A shunt delivery shuttle is positioned within, and is movable relative to, the delivery catheter, the shunt delivery shuttle having a distal portion configured to collapse around an elongate shunt body to thereby transport the shunt body through the delivery catheter, wherein the distal portion self-expands to release the shunt body when the distal shuttle portion is advanced out of the delivery catheter.

Abstract: A device, a method of making a device and a method of inserting a device into a tubular path. The device includes a tubular sheath with one or more helical slots formed therein and a control element that fits within the sheath. In one form, the device is an endoluminal device that simultaneously improves flexibility and structural rigidity though variations in one or both of slot width along the length of the slot and slot pitch along the length of the tubular sheath. When the operator pulls at the proximal end of the control element while holding the outer sheath in place, the slots will tend to close in a preferential manner such that more precise control of device length and bending is enabled, while simultaneously providing improvements in structural rigidity during device insertion and navigation through a body lumen or related tubular member where tortuous paths may be encountered along the member path.

Abstract: Cut-pattern designs creating a frame structure from a solid tube, which may be used as a portion of medical device, such as a catheter. The tube includes a plurality of units of cutout segments which are distributed in band around a circumference of the tube. A tube can have multiple different zones, each having units with varying cutout segments. The cutout segments can have varying cutout surface area allowing the flexibility of the tube to be modified at any point along the tube by altering the cutout surface area with zones having greater cutout surface areas as compared to another zone are more flexible. The tube can be incorporated into a catheter.

Abstract: A guiding catheter has a proximal portion constructed of a tubular braid and a shape-retentive distal portion including a superelastic hypotube cut to define particular mating, support, shape-retentive and flexibility characteristics. A tubular liner extends through both of the tubular braid and the hypotube. The hypotube is joined to the braid using a mechanical interlock that has high torque transfer from the braid to the hypotube. A short portion of high stiffness polymer tube is provided at a joint between the braid and the hypotube. A polymeric outer jacket is provided over the proximal and distal portions, including the polymer tube. The jacket is heat set over the hypotube to remove residual stress.

Abstract: A catheter has a deflection beam with rectangular cross-section and a single continuous puller wire for predictable on-plane bi-directional deflection. The puller wire extends through spacers on opposite sides of the beam so the puller wire is maintained a predetermined separation distance from the beam surface. Tubular structures of the catheter body and the deflectable section are fused at a joint by C-shaped brackets mounted opposite surface of the beam to form a hollow body with holes into which thermoplastic materials covering the catheter body and the deflectable section can melt to form interlocking nodes. Elongated beam stiffeners can be mounted on the beam to provide different curve and deflection geometries.

Abstract: A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes two or more first cut shapes and two or more second cut shapes along a helical path extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions.

Abstract: A catheter assembly including a tapered steering spine having a varying stiffness along an axial length. The tapered steering spine is tailored to provide increasing flexibility from proximal to distal in a way that makes the bend radius more uniform along the length of the steering section. In one embodiment, the tapered steering spine includes structures on adjacent rings that engage with each other when the steering section is flexed to limit the minimum bend radius to a predetermined minimum and which enhances the torsional rigidity of the steering section regardless of the degree of flexure of the steering section. The limited bend radius can prevent excessive bending of components such as fiber optics. The enhanced torsional rigidity can negate the need for torque braid in the section of the catheter shaft that surrounds the tapered steering spine.

Abstract: Catheters are provided which have a high capacity of axial (pushability) and rotational (torquability) movement with relative maximum flexibility and which, at the same time have the ability to adapt to at least partial variations of diameter under the thrust of other catheters or dilators travelling though the lumen or so as to flatten itself at least partially to travel through the lumen of other catheters, such as for example feed catheters.
