Abstract
A urinary catheter of enhanced pushability, for indwelling introduction into a patient's urethra having an effecter within the longitudinal bore of the catheter near its distal end to facilitate an easy introduction of the catheter into the body.
Claims19
A flexible catheter of enhanced pushability, said catheter comprising a main longitudinal axis along which an envelope, having at least one open bore, is in fluid communication between the catheter's proximal and distal ends, wherein said catheter further comprises at least one effecter protruding within said bore and positioned along said envelope within at least one portion of the catheter, such that upon pushing the catheter towards the orifice of a body cavity, and advancing catheter's distal end throughout said cavity, the stiffness of the catheter is greater along said catheters' main axis than in other planes, whilst the flexibility of the catheter is not significantly reduced in other planes.
A flexible catheter of enhanced pushability as defined above, characterized by at least one fold along the longitudinal axis of said envelope, said fold is further characterized by at least one inter-bore portion and envelope-portion, wherein the outer surface of said catheter is continuous defining a well-encapsulated open-bore and wherein the base of the fold has sufficient flexibility that the sides of the fold may approach during insertion or during use, so that the effective diameter of the catheter may be decreased without significantly affecting the cross-sectional area of the open bore, so that fluid flow may be maintained in areas wherein the urethra is constricted.
