Safety needle system operable with a medical device

A safety needle system operable with a medical device, comprising:

• a housing including a needle mount coupled to a setting that approximately axially centers the needle mount within the housing;
• a needle having a distal end insertable through the medical device and a proximal end coupled to the needle mount;
• a sheath telescopically engaged with the housing and having a distal wall defining a needle aperture and a longitudinal track that is substantially parallel to a longitudinal axis of the sheath and slidingly engaged with the setting of the housing, wherein the sheath operates in:
• a retracted position, wherein the sheath exposes the distal end of the needle;
• and
• an extended position, wherein the sheath substantially surrounds the distal end of the needle;
• wherein the sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, thereby transitioning the sheath from the retracted position to the extended position;
• and
• a locking mechanism configured to about a proximal portion of the sheath against a stop in the extended configuration, thereby locking the sheath in the extended configuration.

A safety needle system operable with a vascular delivery system adapted to be placed about a catheter insertion site on a patient, wherein the vascular delivery system includes a frame with a catheter hub providing a first anchoring point on the patient, a stabilization hub providing a second anchoring point on the patient, and at least one lateral member extending between the catheter hub and stabilization hub, wherein the first and second anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter, the safety needle system comprising:

• a housing including a needle mount;
• a needle having a distal end insertable through the catheter hub and a proximal end coupled to the needle mount;
• a sheath telescopically engaged with the housing and circumferentially surrounding at least a portion of the needle, wherein the sheath operates in:
• a retracted position, wherein the sheath exposes the distal end of the needle;
• and
• an extended position, wherein the sheath substantially surrounds the distal end of the needle;
• wherein the sheath is coupleable to the catheter hub such that removal of the needle from the medical device draws the sheath over the needle, thereby transitioning the sheath from the retracted position to the extended position;
• and
• a slider, longitudinally engaged with at least one of the housing, sheath, and needle and including a restraint that selectively couples to the sheath, wherein:
• when the restraint is coupled to the sheath, the restraint reinforces the coupling of the sheath to the catheter hub;
• and
• when the restraint is uncoupled from the sheath, the restraint weakens the coupling of the sheath to the catheter hub.
