摘要： A tearaway sheath assembly (100) having a splittable sheath tube (102) a splittable hub (110), a split valve (150,250) and a split cap (180). The valve (150,250) has a slit (158,258) at least partially across the transverse distal section (154) such that transverse distal section may be displaced laterally during insertion through the slit (158,258), of a dilator (200) or a catheter. The valve (150,250) is formed in two separate halves (152A,152B;252) that are fused or adhered to each other to form a sealed weak bond (154) that is easily broken during splitting of the sheath; each valve half is mechanically affixed in a proximal valve-receiving recess (130) of the hub such as by anchor posts (136) extending through apertures (166A,166B) in ears (164A,164B) of each valve half. A two-part cap (180) is affixed to the hub proximal end (120) and traps the valve between itself and the hub. Pairs of opposed gaps (184,122) of the cap (180) and the hub (110) are aligned with lines of weakness or seams (106) of the sheath tube (102) and the weak bond (154) of the valve, facilitating splitting of the assembly (100) when desired by the practitioner to peel it away from the inserted catheter.

摘要： A tearaway introducer sheath assembly (10) for use in implantation of a catheter into a patient, having an elongated polytetrafluoroethylene sheath tube (12) and a proximal polyethylene hub component (16). The hub comprises two halves (22) insert molded about the sheath tube proximal end and joined to each other by frangible webs (28) enabling manual splitting. At least one pair of opposed holes (42) is formed through the tube proximal end portion 44, and a polyethylene liner (46) is inserted into the tube's proximal end portion. The polyethylene flows into the at least one pair of holes (42) to fuse with the liner, establishing a pair of physical joints (50′) integrally joining the liner (46) to a respective hub half (22). Upon manual splitting of the hub halves, the sheath tube easily splits along its length as a result of a property of the polytetrafluoroethylene material.

摘要： A releasably locking dilator and sheath assembly and methods for releasing the dilator from the sheath and longitudinally splitting the sheath are provided. The assembly includes a dilator having a dilator hub and a sheath having a sheath hub. The sheath hub has two opposing winged tabs, each tab having a perpendicular portion and an angled portion as well as a female threaded portion. The dilator hub has a male threaded portion designed to engage the female threaded portion of the sheath hub. The dilator is released from the sheath by rotating the dilator 90° in relation to the sheath and pulling the dilator out of the sheath. The sheath is longitudinally split by creating a couple on each of the winged tabs thereby forcing the sheath and the sheath hub to split longitudinally. With the sheath and sheath hub split longitudinally, the sheath is removed from around a catheter while leaving the catheter in place.

摘要： A steerable catheter having a segmented tip formed from materials of differing hardnesses. A tip segment formed of softer material provides improved steerability, while an adjacent harder segment provides improved resistance against steering wire pull-through. Wear-resistant sleeves and a coined loop portion of steering wire provide additional resistance against steering wire pull-through. A tip fabrication method is also disclosed. The catheter includes a one-piece inlet housing with integral mounting fins for attachment to the catheter housing.

摘要： A dialysis catheter which includes a first tube having a first tube distal end with an intake port and a second tube that extends parallel to and is connected to the first tube, with the second tube having a second tube distal end with a discharge port is provided. A cover is located on the first tube that it movable from a first position, in which it blocks the intake port, to a second position, which the intake port is unblocked. A longitudinally extending control wire hole is defined in a wall of the first tube. A control wire extends through the hole, with the control wire having a first end that is fixed to the cover. The second end of the control wire is connected to a switch that is moveable in order to move the cover between the first and second positions. This arrangement helps to prevent blockage of the arterial intake port due to thrombosis and fibrin buildup.
