Needle targeting apparatus for implanted device

摘要

A needle targeting apparatus comprises a sense head configured to locate an implanted device and a guide. The guide is associated with the sense head and comprises an upper surface, a lower surface, and a support member. The support member comprises a channel extending through the support member that provides access to an injection site. In some versions, a needle targeting apparatus comprises a locating feature, an alignment feature, and a support feature. The locating feature is configured to locate an implanted device. The alignment feature is configured to align a syringe needle with the implanted device. The support feature is configured to support a syringe upon insertion of the syringe needle into the implanted device. In some versions, a needle targeting apparatus comprises a sense head configured to locate an implanted device and a guide. The guide is configured to identify the center of the sense head.

主权项

1. A needle targeting apparatus comprising:
(a) an implantable device, wherein the implantable device comprises an internal control module; (b) a sense head, wherein the sense head comprises:
(i) an external control module including an antenna configured to locate the implantable device, wherein the external control module is operable to communicate with the internal control module, and(ii) an annular member defining an opening having a center point and including an inner face facing the central point; (c) a guide, wherein the guide is configured to visually indicate a needle insertion point relative to the opening defined by the sense head, wherein the guide comprises a first laser and a second laser disposed on or near the inner face, wherein the first laser and the second laser form an intersecting point positioned within the opening, wherein the intersecting point is proximate to the center point, wherein the first laser and the second laser define a plane within the opening operable to receive a needle transverse to the plane; and (d) a laser module operably configured to selectively power the first laser and the second laser, wherein the laser module is operable to vary performance of the first laser and the second laser based on the strength of a signal between the internal control module and external control module.
