Embodiment Construction

[0066] will now refer to figure 2 An example of a catheter 200 for insertion into a blood vessel of a patient is described. It should be understood that the term catheter as used herein refers to a range of medical devices used for insertion into a patient's blood vessels, including those used to deliver intravenous (IV) fluids (such as drugs, nutrition, etc.) to a patient or to draw blood or fluids Peripheral venous catheters (PIVC) or midline catheters for sampling, arterial catheters for blood aspiration and hemodynamic monitoring, and other types of catheters such as renal arteriovenous fistula (AVF) catheters, central venous catheters, etc.

[0067] A midline catheter (usually 7.5 cm to 20 cm long) is inserted near the cubital fossa into the basilic, cephalic, or brachial veins. The catheter tip does not extend beyond the distal axillary vein in the upper arm.

[0068] In this example, catheter 200 includes an elongated body 210 extending between a proximal end 211 att...

Abstract

The present disclosure relates to a catheter for insertion into a vessel of a patient, the catheter including an elongate body extending between a proximal end for attachment to a hub and a distal endat a tip portion thereof, the body having a circumferential wall and including a first portion that extends a first length from the proximal end and defines an enclosed section of the wall and a second portion that extends a second length from an end of the first portion towards the tip portion, the second portion defining an at least partially open section of the wall having a plurality of openings arranged to permit fluid flow into and out of the second portion of the body.

Description

[0001] priority document [0002] This application claims priority to Australian Provisional Application No. 2016903005, filed 29 July 2016, entitled "IMPROVED CATHETER" and 2017901464, filed 21 April 2017, entitled "IMPROVED CATHETER" , the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates to catheters and, in one example, to a peripheral intravenous catheter (PIVC) or midline catheter for administering intravenous fluids, blood products and medications to a patient or drawing blood or fluids for sampling. In another example, the invention relates to an arterial catheter for hemodynamic monitoring and blood sampling aspiration. Background technique [0004] References in this specification to any prior publication (or information derived therefrom) or to any known matter are not, and should not be deemed to be, references to prior publications (or information derived therefrom) or known matters ...
