Flexible elongate surgical needle device having a tissue engaging section being of greater flexibility than an intermediate section, and methods of using the device

A kit for a surgical needle device suitable for delivery of medication and aspiration biopsy, comprising:

• a main body having a stationary member and adjustable member moveable between first and second positions relative to the stationary member, the adjustable member having proximal and distal openings defining a main body channel;
• a syringe configured to be secured to the adjustable member proximal opening in communication with the main body channel;
• an elongate sheath comprising proximal and distal ends having openings defining a sheath channel, the proximal end configured to be secured to the stationary member;
• an elongate needle slideably positioned axially within the sheath channel, the needle having a proximal end comprising an opening, an intermediate section, and a flexible distal end comprising an opening, the openings defining a needle channel there between, the flexible distal end operatively coupled to the intermediate section and the proximal end configured to be secured to the adjustable member with the needle channel in communication with the main body channel, the needle distal end further comprising a tissue engaging section comprising a first material and the intermediate section comprising a second material, the first material being more flexible than the second material,
• wherein the tissue engaging section has greater flexibility than the intermediate section.

A method of using a surgical needle device, comprising the steps of:

• providing a surgical needle device configured to deliver at least one of medication and aspiration biopsy, the surgical needle device configured to be connected to a syringe and having an elongate needle moveable between first and second positions and having a proximal end, an intermediate section, and a flexible distal end operatively coupled to the intermediate section, the distal end comprising a tissue engaging section comprising a first material and an intermediate section comprising a second material, the distal end tissue engaging section first material having greater flexibility than the intermediate section second material;
• introducing the needle distal end to a surgical site;
• setting the first and second positions for the needle;
• and
• advancing the needle distal end tissue engaging section into the surgical site.
