摘要： A catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible body, having a proximal end, a distal end and a side wall defining a central lumen. A distal zone of the side wall includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, adjacent windings of the coil spaced progressively further apart in the distal direction. An outer jacket surrounds the helical coil. The outer jacket is formed from a plurality of tubular segments positioned end to end, coaxially about the coil. The flexural load profile of the catheter as a function of catheter length is configured to provide enhanced distal flexibility while maintaining high backup support.

摘要： A method of making a seal-set for a rotary catheter drive unit containing a motor and a seal-set, an output shaft of the motor being power transmittingly connected to a flexible shaft that is rotatably disposed through the seal-set, the seal-set comprising a bearing and an adjacent seal defining a first and a second concentric bores, respectively, the first bore being slightly larger than a diameter of the shaft so that it rotatably and accurately supports the shaft, the second bore being slightly smaller than the diameter so that it seals around the shaft, the bearing aligning the shaft, so that it is concentric with the second bore, by deflecting the shaft to compensate for eccentricity and misalignment of the second bore relative to the output shaft of the motor.

摘要： A tissue anchoring system includes a tissue anchor member that is suitable for anchoring against tissue. The system also includes a tensioning member operatively connected to the anchor member such that the anchor member can slide relative to the tensioning member, the tensioning member capable of being pulled to cause the anchor member to move relative to the tensioning member into a position seated against the tissue. A hand operated deployment catheter is operable to extend and deploy the anchor member therefrom. The deployment catheter includes a rotatable member about which the tensioning member is routed and a clutch assembly for limiting tension within the tensioning member to prevent the deployed anchor from being pulled through the tissue.

摘要： A retrieval medical device for entrapping and retaining an object located in a body for its extraction therefrom is described. The device includes a basket-filter constituted by a plurality of filaments extending from the proximal end towards the distal end. The filaments are bound together in the vicinity of the proximal end to form a plurality of main branches. Each main branch includes at least two filaments. The filaments are entangled together in the vicinity of the distal end. Each main branch has a ramification point at which it ramifies into at least two single filaments extending from the ramification point towards the basket distal end of the basket-filter. One of the single filaments extends in the form of a right spiral, whereas another single filament extends in the form of a left spiral. The filaments extending from the ramification points interlace with each other, thereby forming a mesh between the branching point and the basket proximal end having density greater than 5.1 crossover points per inch.

摘要： A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

摘要： A device for removing a thrombus from a retinal vessel has a grip held by the user of the device, a tubular portion to be inserted into the eye, the tubular portion being provided at an end of the grip, a microtube to be inserted into a retinal vessel, the microtube being provided at an end of the tubular portion, a linear pusher axially slidably held in the microtube and the tubular portion, and an operating portion provided at the grip. The linear pusher is adapted to protrude to a desired position from an end of the microtube by axially sliding the linear pusher by means of the operating portion, thereby the linear pusher physically pushes a thrombus out of the retinal vessel.
