摘要:
A flexible medical device conduit includes an elongated framework formed from a flexible material (e.g., Nitinol) with a body portion, sharp head, distal end and proximal end. The flexible medical device conduit also includes a flexible tube at least partially jacketing the elongated framework between the distal end and the proximal end. Moreover, the sharp head is disposed at the distal end and is configured for subcutaneous skin insertion and the elongated framework and flexible tube define at least one conduit between the elongated framework and the flexible tube, the conduit having an opening at the distal end.

A medical device includes a medical device flexible conduit that has an elongated Nitinol strip with a distal end, a proximal end, a longitudinal axis running from the distal end to the proximal end, a sharp head extending from the distal end, and a channel etched therein. Moreover, the channel is dispositioned along the longitudinal axis. The medical device flexible conduit also has a flexible tube at least partially jacketing the elongated Nitinol strip between the distal end and the proximal end, with the channel and the flexible tube defining a conduit. The medical device also includes an insertion mechanism configured to insert a portion of the flexible conduit, including the sharp head, into a user's target site such that the conduit provides fluid communication to the target site.

A method for manufacturing a medical device flexible conduit includes etching a channel into an elongated Nitinol strip and forming a sharp head on a distal end of the elongated Nitinol strip. The method also includes subsequently jacketing the flat elongated Nitinol strip with a flexible tube such that the flexible tube and channel define a conduit.

A method for inserting a medical device flexible conduit into a user's target site includes adhering a medical device to a user with the medical device including a medical device flexible conduit and an insertion mechanism. Moreover, the medical device flexible conduit has an elongated Nitinol strip with a distal end, a proximal end, a longitudinal axis running from the distal end to the proximal end, a sharp head extending from the distal end, and a channel etched therein. In addition, the channel is dispositioned along the longitudinal axis. The medical device flexible conduit also includes a flexible tube at least partially jacketing the elongated Nitinol strip between the distal end and the proximal end, the channel and flexible tube defining a conduit. The insertion mechanism is configured to insert a portion of the flexible conduit including the sharp head into a user's target site such that the conduit provides fluid communication to the target site.

摘要:
A method for manufacturing a flexible medical device conduit includes forming an elongated framework of flexible material (e.g., Nitinol), and creating a sharp head on a distal end of the elongated strip using, for example, an isotropic etching technique, a stamping technique and/or a coining technique. The method also includes the step of jacketing the elongated framework with a flexible tube such that the flexible tube and the elongated framework define at least one conduit therebetween.

Disclosed is a device for the parenteral delivery of a medication, such as a drug. The device includes upper and lower housings in which the upper housing is configured to move relative to the lower housing as a result of application of an external force to permit the user of the device to control the rate at which the drug is administered.

A method for inserting a flexible medical device conduit includes adhering a flexible conduit insertion medical device, with a flexible medical device conduit and an integrated insertion mechanism, to a target site. Moreover, the flexible medical device conduit has an elongated framework formed from a flexible material (e.g., Nitinol) with a body portion, sharp head, distal end and proximal end. The flexible medical device conduit also has a flexible tube at least partially jacketing the elongated framework between the distal end and the proximal end. In addition, the sharp head is disposed at the distal end and is configured for subcutaneous skin insertion and the elongated framework and flexible tube define at least one conduit between the elongated framework and the flexible tube, the conduit having an opening at the distal end. The insertion mechanism is operatively connected to, and integrated with, the flexible medical device conduit and the insertion mechanism is configured to insert a portion of the flexible medical device conduit, including at least the sharp head and the opening, into a user's skin target site. The method also includes inserting the flexible medical device conduit into the target site by action of the insertion mechanism.

摘要:
An adjustable length shaft assembly including a handle portion and an extensible shaft. An upper end of the shaft includes a set of locking teeth. The handle has an internal locking mechanism with a tooth rack to accommodate the locking teeth. A control handle is rotated in a first direction, rotating the teeth away from the tooth rack, where the teeth are in a disengaged, unlocked position. With the teeth unlocked, the shaft can be longitudinally adjusted to achieve the desired length. Then, the control handle is rotated in a second direction, rotating the teeth into the tooth rack, where the teeth are in an engaged, locked position. In this manner, the teeth and the tooth rack provide a plurality of positive locking positions, each position providing a different shaft length.
