Abstract
A catheter system including a catheter (10) and a stylet (30). The stylet includes an elongate portion (31) and a shaped portion (32). The elongate portion is receivable within the catheter. The elongate portion and the catheter are co-operably configured such that, when the elongate portion is so received, at least a portion of the elongate portion is spaced from the catheter such that the at least portion and the catheter together define at least one elongate void for conveying fluid along the catheter at least one of to or from one or more sites within a patient. The shaped portion is positioned to be within the patient.

47. A stylet for a catheter system, the stylet including:
-
an elongate portion and a connector; the elongate portion being receivable within a catheter and configured such that, when the elongate portion is so received, at least a portion of the elongate portion is spaced from the catheter such that the at least portion and the catheter together define at least one elongate void; wherein the elongate void(s) is configured to run from external the patient to within the patient to convey fluid along the catheter at least one of to or from one or more sites within a patient; and the connector is configured to sealingly engage the catheter external the patient and define one or more flow paths open to the void(s). - View Dependent Claims (48, 49, 50, 51, 52, 53)

61. A catheter system including:
-
a catheter; a needle; a stylet; and a connector; the stylet including an elongate portion;
the elongate portion being receivable within the catheter;
the elongate portion and the catheter being co-operably configured such that, when the elongate portion is so received, at least a portion of the elongate portion is spaced from the catheter such that the at least portion and the catheter together define at least one elongate void for conveying fluid along the catheter at least one of to or from one or more sites within a patient;the needle being receivable within the catheter to insert the catheter into the patient; the connector being configured to be external to the patient and to define one or more flow paths open to the elongate void(s).

62. A catheter system including:
-
a catheter; and a stylet;
the stylet including an elongate portion;
the elongate portion being receivable within the catheter;
the elongate portion and the catheter being co-operably configured such that, when the elongate portion is so received, at least a portion of the elongate portion is spaced from the catheter such that the at least portion and the catheter together define at least one elongate void for conveying fluid along the catheter at least one of to or from one or more sites within a patient;the catheter being a flexible catheter capable of kinking when the stylet is so inserted; and
the stylet being configured to prevent occlusion of the catheter due to the kinking. - View Dependent Claims (63)

64. A catheter system for fluidly communicating, via at least one elongate void, with one or more sites within a patient, the system including:
-
a catheter having an open end positionable within the patient; a stylet; and a connector; the stylet including an elongate portion and a shaped portion; the elongate portion being receivable within the catheter;
the elongate portion and the catheter being co-operably configured such that, when the elongate portion is so received, at least a portion of the elongate portion is spaced from the catheter such that the at least portion and the catheter together define the at least one elongate void;wherein the elongate void is configured to run from external the patient to within the patient to convey fluid along the catheter at least one of to or from the one or more sites within a patient; the shaped portion is positionable within the patient beyond the open end and shaped to act upon build-up about the open end such that the stylet is withdrawable to remove the build-up; and at least a rearward portion of an exterior of the shaped portion rearwardly converges to guide the shaped portion into the catheter;
the connector being configured to be external to the patient and to define one or more flow paths open to the elongate void(s).- View Dependent Claims (65, 66)
