Abstract
A delivery needle apparatus in which a sleeve is fitted over an exterior surface of a delivery needle and methods of manufacturing the same. An elongate medical device may be delivered through the interior of the delivery needle and out of an opening in the distal end of the delivery needle (i.e., the delivery opening). The sleeve may cover a proximal portion of the delivery opening and may align an elongate medical device during insertion and/or withdrawal through the delivery opening.
Claims21
A delivery needle apparatus comprising:
- a delivery needle body extending along a longitudinal axis from a proximal end to an insertion section, wherein the delivery needle body comprises a needle wall defining a lumen that extends into the insertion section, and wherein the delivery needle body further comprises a delivery opening located within the insertion section, wherein the delivery opening is in fluid communication with the lumen;
- and
- a sleeve fixedly attached to the delivery needle body by friction between an inner surface of the sleeve and an exterior surface of the needle body, wherein at least a portion of the delivery opening is contained within the sleeve, wherein the fixedly attached sleeve is attached to the needle body in a manner that prevents movement of the sleeve relative to the needle body during use of the delivery needle apparatus.
A delivery needle apparatus comprising:
- a needle body extending along a longitudinal axis from a proximal end to an insertion section, wherein the needle body comprises a needle wall defining a lumen that extends into the insertion section;
- a delivery opening formed through the needle wall within the insertion section, wherein the opening comprises a longitudinal length measured along the longitudinal axis, and wherein the opening is in fluid communication with the lumen;
- and
- a sleeve fixedly attached to the needle body, wherein the sleeve is fitted over an exterior surface of the needle body, and wherein the sleeve comprises a distal sleeve end that covers only a proximal portion of the delivery opening such that a portion of the delivery opening is not covered by the sleeve, wherein the delivery opening extends underneath the distal sleeve end towards the proximal end of the needle body, and wherein the fixedly attached sleeve is attached to the needle body in a manner that prevents movement of the sleeve relative to the needle body during use of the delivery needle apparatus.
