RAPID EXCHANGE FNA BIOPSY DEVICE WITH DIAGNOSTIC AND THERAPEUTIC CAPABILITIES
A device for needle biopsy and delivery of a diagnostic or therapeutic agent is presented. The device includes a handle member having proximal and distal portions. A proximal handle member is disposed to the proximal portion of the handle member and a distal handle member is disposed to the distal portion of the handle member. A sheath lumen is disposed within the handle member and extends from the distal portion of the handle member. A needle housing member is partially disposed to the proximal portion of the handle member and a needle is disposed within the sheath lumen. The needle housing member includes one or more ports for introducing an agent or a device into the housing member. The needle can include an agent or a device disposed at a distal portion thereof.
1 . A device for needle biopsy, comprising:

a needle housing member partially disposed in the proximal handle member and comprising at least two ports for introducing a device or agent, wherein said needle housing member is moveable in a substantially transverse direction relative to the longitudinal axis of the handle member; and
a needle disposed within the sheath lumen.
2 . The device of claim 1 , wherein said agent is a therapeutic agent selected from the group consisting of: a chemotherapeutic agent, a sclerosing agent, a necrosing agent, a growth factor, and a radiation agent.
3 . The device of claim 1 , wherein said device introduced into the needle housing member is a stylet, a syringe or a fiber optic probe.
4 . The device of claim 1 , wherein the needle housing member further comprises a strain relief.
5 . The device of claim 1 , wherein the needle housing member further comprises a connecting member comprising at least one indentation for engaging to at least one adaptation member in the proximal handle member.
6 . The device of claim 1 , wherein the proximal handle member includes a release member that engages and disengages the needle housing member.
7 . The device of claim 6 , wherein the release member is depressible.
8 . A device for needle biopsy, comprising:
a handle member having proximal and distal portions;
a proximal handle member disposed to the proximal portion of the handle member;
a distal handle member disposed to the distal portion of the handle member;
a sheath lumen disposed within the handle member and extending from the distal portion of the handle member;

a needle disposed within the sheath lumen, said needle comprising an agent or a device disposed at a distal portion thereof.
9 . The device of claim 8 , wherein said agent is a therapeutic agent selected from the group consisting of: a chemotherapeutic agent, a sclerosing agent, a necrosing agent, a growth factor, and a radiation agent.
10 . The device of claim 8 , wherein said agent is a diagnostic agent selected from the group consisting of a fiduciary marker, a biomarker, and an imaging probe.
11 . The device of claim 8 , wherein said agent is encapsulated in a membrane or capsule.
12 . The device of claim 8 , wherein said agent comprises a pellet or a seed form.
13 . The device of claim 8 , wherein said device disposed at the distal portion of the needle is a pacing lead or a stent.
14 . The device of claim 8 , wherein said needle housing member further comprises at least one port for introducing a device.
15 . The device of claim 14 , wherein said device introduced into the needle housing member is a stylet, a syringe or a fiber optic probe.
16 . The device of claim 8 , wherein the needle housing member further comprises a connecting member comprising at least one indentation for engaging to at least one adaptation member in the proximal handle member.
17 . The device of claim 16 , wherein the proximal handle member includes a release member that engages and disengages the needle housing member.
18 . The device of claim 17 , wherein the release member is depressible.
19 . A device for needle biopsy, comprising:
a handle member having proximal and distal portions;
a proximal handle member disposed to the proximal portion of the handle member;
a distal handle member disposed to the distal portion of the handle member;
a sheath lumen disposed within the handle member and extending from the distal portion of the handle member;
a needle housing member partially disposed in the proximal handle member and comprising an indicator assay insert mounted to an inner wall in a proximal portion of the needle housing member
needle hub contains an assay loaded insert indicator housed internally and mounted to the inner wall of the needle hub; and
