Method and apparatus for repositioning a percutaneous probe
First Claim
1. An apparatus for percutaneously transferring a flowable substance to and/or from a recipient, the apparatus comprising:
- a housing extending in an axial direction and having an engaging surface positioned to engage the recipient and defining a central first axis; and
a probe movably received within the housing, the probe having a passageway and an end shaped to pierce the recipient'"'"'s skin, the end having an aperture in fluid communication with the passageway, the probe being movable in the axial direction along a second axis generally parallel to the first axis, and between a first position in which the end is received within the housing and a second position in which the end is external to the housing.

Abstract
An apparatus for piercing a skin surface, and methods for operating and manufacturing such an apparatus. In one embodiment, the apparatus can include a support housing having an engaging surface to engage the skin surface. The support housing can include a first guide extending axially away from the engaging surface and a second guide extending transverse to the first guide. The apparatus can further include a probe coupled to a guide member with the guide member sequentially engaged with the first guide and the second guide to move in a first direction toward and away from the engaging surface without simultaneously moving in a second direction transverse to the first direction. Accordingly, a practitioner can reposition the probe from one location to the other (for example, by orbiting the probe relative to a central axis of the support body, or by translating the probe linearly relative to the support body) without moving the housing relative to the skin surface.

15. An apparatus for piercing a skin surface, comprising:
-
a support housing having a casing defining an axial direction and an engaging surface to engage the skin surface at one end of the casing, and the support housing defining a central first axis; and a probe movably supported relative to the support housing and moveable relative to the support housing in an axial direction along a second axis generally parallel to the first axis, and toward and away from the engaging surface between a first position a first distance from the engaging surface and a second position a second distance from the engaging surface greater than the first distance. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. An apparatus for percutaneously transferring a flowable substance to and/or from a recipient, the apparatus comprising:
-
a base including an engagement surface and a cavity extending along a first axis transverse to the engagement surface, the engagement surface being positioned to engage a skin of the recipient; a slider movably disposed within the cavity, the slider having a probe aperture; a probe positioned within the probe aperture of the slider and projecting away from the slider along a second axis at least generally parallel to the first axis, the probe having a passageway and an end shaped to pierce the recipient'"'"'s skin, the probe being coupleable to a flowable substance reservoir; and a plunger elongated along the first axis and having an engagement member to move the slider axially along the first axis from a first position with the end of the probe received within the base to a second position with the end of the probe external to the base. - View Dependent Claims (23, 24, 25)
