Temporary retention device
First Claim
1. A device for subcutaneously anchoring a coupled medical device within a patient, comprising a distal section and a proximal section with a deployable section attached proximate the proximal section wherein when the device is introduced the deployable section when deployed deploys subcutaneously in a controllable manner.

Abstract
A retention device for anchoring indwelling catheters, sheath introducers, feeding tubes, ostomy bags or other medical devices beneath the skin of a patient includes an deployable section coupled to a medical device; following introduction into a patient, the deployable section is subcutaneously deployed, securely anchoring the device and coupled medical device for the duration of treatment.

6. A device for subcutaneously anchoring a coupled medical device within a patient, comprising:
-
a. a restraint;
b. an anchor mechanism contacting the restraint, at least a portion of the anchor mechanism capable of transitioning between a first configuration when restrained by the restraint and a second configuration when unrestrained by the restraint, the anchor mechanism having at least a single extension, at least a portion of the extension is capable of flexibly and repeatedly moving between the first configuration and the second configuration; and
c. the device defining a distal section and a proximal section, the restraint and anchor mechanism proximate the proximal section;
whereby separating the anchor mechanism and the restraint from each other following introduction of the device unrestrains the extension in a gradual and controlled manner causing the extension to gently transition from the first configuration toward the second configuration, resulting in subcutaneous deployment of the extension. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A device for subcutaneously anchoring a coupled medical device within a patient, comprising:
-
a. an anchor sleeve having a chamber defining at least a single port;
b. an anchor mechanism movably loaded into the chamber, the anchor mechanism capable of moving between a restrained first configuration and an unrestrained second configuration, the anchor mechanism having;
i at least a single tine having a first end and a second free end, (1) the second end of the tine is capable of flexibly and repeatedly moving between the first configuration and the second configuration, (2) the tine having a trained shape when in the second configuration, (3) the length of the tine is such that the tine is restrained within the chamber when the anchor mechanism is in the first configuration, and (4) the port is sized and located so the free end of the tine is proximate the port when the tine is in the first configuration;
ii. biasing means to move the anchor mechanism into the second configuration; and
iii. a removable actuation key sized to fit into the anchor sleeve to contact the anchor mechanism;
whereby inserting the key into the anchor sleeve moves the anchor mechanism from the second configuration and retains in the first configuration causing the second end of the tine to enter the chamber through the port. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)

31. A device for subcutaneously anchoring a coupled medical device within a patient, comprising:
-
a. an anchor sleeve having a chamber defining a longitudinal axis and at least a single port;
b. an anchor mechanism movably loaded into the chamber, the anchor mechanism capable of moving between a restrained first configuration and an unrestrained second configuration, the anchor mechanism having;
i. at least a single loop capable of extending from the port, (1) the loop is capable of repeatedly moving between the first configuration and the second configuration, (2) the loop having a trained shape when in the second configuration, and ii. biasing means to move the anchor mechanism into the second configuration; and
iii. a key sized to fit into the anchor sleeve to contact the anchor mechanism;
whereby inserting the key into the anchor sleeve moves the anchor mechanism from the second configuration to the first configuration causing the loop to enter the chamber through the port. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39)

40. A device for subcutaneously anchoring a coupled medical device within a patient, comprising:
-
a. an inner sheath defining an outer dimension and an outer sheath defining an inner dimension, the outer dimension of the inner sheath sized to slidably fit inside the inner dimension of the outer sheath, the outer sheath defining a sliding end, the sliding end movable along the inner sheath; and
b. a braid defining a length and a width, the braid attached at a first point to the sliding end of the outer sheath and at a second point to the inner sheath, the braid capable of moving between an elongated configuration having a greater length and a lesser width and a shortened configuration having an inverse relationship between length and width;
wherein when the sliding end of the outer sheath is moved the full distance of its travel from the point of braid attachment on the inner sheath, the braid assumes the elongated configuration and the device can be introduced or removed from the patient, and when the sliding end of the outer sheath is moved in a direction toward the point of braid attachment on the inner sheath, the braid moves toward the shortened configuration and the braid defines a widest circumference. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48)
