STRENGTHENED VENENZUGANGSKATHETER

MEDICAL DEVICES

NANO PARTICLE ADDITIVES FOR VENOUS ACCESS CATHETER

Described is a catheter which includes a reinforced polymer shaft. The polymer includes nano particles having a dimension of less than about 6nm. Described is also a method of forming a medical device. Granules of a selected polymer are prepared. Reinforced granules of the selected polymer are prepared. The reinforced granules include nano particles. The granules and the reinforced granules are then mixed in a ratio selected to obtain a desired concentration of the nano particles. The granules and the reinforced granules are extruded to form a substantially tubular element.

Embolic compositions

Embolic compositions and methods of delivering the compositions are disclosed. In some embodiments, the embolic compositions include a shape memory material.

Verstärkter Venenzugangskatheter

Reinforced venous access catheter

A catheter for medical procedures comprises a shaft portion having a distal end insertable into a body lumen, the shaft portion having a wall defining a working lumen extending therewithin and a first strengthening element coupled to the wall to increase a burst pressure of the shaft portion, wherein the first strengthening element cooperates with a base material of the wall to define a flexible region of the shaft portion allowing the shaft portion to be atraumatically inserted into the body lumen.

REINFORCED VENOUS ACCESS CATHETER.

Un catéter para procedimientos médicos que comprende: una porción de vástago que tiene un extremo distal insertable en un lúmen del cuerpo, incluyendo la porción de vástago una pared que define un lúmen operativo que se extiende por dentro de la misma; y un primer elemento de refuerzo que aumenta la presión de rotura de la porción de vástago, en el cual el primer elemento de refuerzo coopera con un material base de la pared para definir una región flexible de la porción de vástago que permite al vástago ser atraumáticamente insertado en el lúmen del cuerpo, estando la pared formada por una primera capa de un material que tiene un valor durométrico mayor que el de un material comprendido en una segunda capa de la pared, y en el cual una superficie interior de la primera capa define una superficie exterior del lúmen operativo, y en el cual la pared comprende una porción reforzada y una porción no reforzada separadas longitudinalmente la una de la otra a lo largo de un eje de la porción de vástago. A catheter for medical procedures comprising: a stem portion having a distal end insertable in a body lumen, the stem portion including a wall defining an operative lumen extending therein; and a first reinforcing element that increases the breaking pressure of the rod portion, in which the first reinforcing element cooperates with a base material of the wall to define a flexible region of the rod portion that allows the rod to be atraumatic inserted into the lumen of the body, the wall being formed by a first layer of a material having a durometric value greater than that of a material comprised in a second layer of the wall, and in which an inner surface of the first layer defines an outer surface of the operative lumen, and in which the wall comprises a reinforced portion and an unreinforced portion longitudinally separated from each other along an axis of the stem portion.
