Abstract
An introducer set (1) for providing vascular access in a patient's body comprises an introducer sheath (10) and a dilator (20). The introducer sheath (10) has a tubular body (11) made of flexible material with a distal portion (12), a proximal portion (13) and an inner surface, the proximal portion (13) being configured to be inserted into a patients vessel to allow a medical device (100) to be inserted through the introducer sheath (10) into the patient's vessel. At least one of the dilator (20) and the introducer sheath (10) comprises a stiffening structure (25) imparting stiffness to the tubular body (11) of the introducer sheath (10), wherein said stiffening structure (25) can be released, removed or otherwise deactivated.
Claims28
An introducer set for providing vascular access in a patient's body, comprising:
- an introducer sheath having a tubular body made of flexible material with a distal portion, a proximal portion and an inner surface, the proximal portion being configured to be inserted into a patient's vessel to allow a medical device to be inserted through the introducer sheath into the patient's vessel;
- and
- a dilator having a body with a proximal portion, a distal portion and an outer surface, the dilator being insertable into the introducer sheath such that its proximal portion extends proximally of the introducer sheath when the dilator is inserted in the introducer sheath;
- wherein the tubular body of the introducer sheath has a wall thickness of 0.3 mm or less;
- and
- wherein at least one of the dilator and the introducer sheath comprises a stiffening structure imparting stiffness to the tubular body of the introducer sheath, wherein said stiffening structure can be released, removed or otherwise deactivated.
A dilator configured for use in an introducer sheath, comprising a body with an outer surface, wherein the dilator is collapsible so as to allow for decreasing a cross-section of the body in order to decrease surface friction between the outer surface and an inner surface of the introducer sheath.
An introducer sheath comprising a tubular body made of a flexible material with a distal portion and a proximal portion, the proximal portion being configured to be inserted into a patient's vessel to allow a medical device to be inserted through the introducer sheath into the patient's vessel, wherein the tubular body has a wall thickness of 0.3 mm or less.
The introducer sheath according to claim 28, wherein the tubular body has a wall thickness of 0.15 mm or less.
The introducer sheath according to claim 29, wherein the tubular body has a wall thickness of 0.1 mm or less.
