Patent number: 9138563Abstract: A retainer is provided which can be affixed to a medical tube, such as a catheter, or formed with the tube. The retainer has a base portion which is fixed to the tube. An expandable width portion is coupled to the base portion. This expandable width portion can transition between a collapsed configuration and an expanded configuration, with the expanded configuration wider than the base portion and the collapsed configuration narrower than the expanded configuration. This retainer is located on a portion of the tube which is subcutaneous but near the skin. After the tube is positioned where desired, the retainer is transitioned from the collapsed configuration to the expanded configuration. The retainer then resists removal of the tube, due to the expanded width of the retainer and its location beneath the skin. The tube fitted with the retainer can be a PICC line or other form of medical tube.Type: GrantFiled: March 30, 2007Date of Patent: September 22, 2015Assignee: Stealth Therapeutics, Inc.Inventor: Bradley J.

Patent number: 8876788Abstract: The subcutaneously implantable vascular access port has two parts including a body and a wing. The body supports a chamber covered by a septum, with a septum held in place over the chamber by a collar. The chamber is coupleable to a vascular structure, such as through tubing extending from the body, for delivery of medical preparations. The body is preferably elongate in form. The wing is configured to be adjustable in width. In one embodiment the wing rotates relative to the body and has an elongate form similar to that of the body. When the wing is rotated it extends laterally from the body and enhances a stability of the body. In another embodiment, the wing is provided as a deformable wing which can expand laterally out of side openings of a cavern in the body into which the deformable wing is inserted.Type: GrantFiled: September 13, 2012Date of Patent: November 4, 2014Assignee: Stealth Therapeutics, Inc.Inventor: Bradley J.

Patent number: 8425476Abstract: A vascular access port is described that is elongate in form. A distal end is coupled to a tube which leads into a body lumen. A proximal end has a head thereon with a septum which can be repeatedly penetrated by a needle and reseal, for repeated administration of medications or other compositions through the port and into the body of the patient. A wing is attached to the body that has two positions including a streamlined first position for implantation and a wider second position for stabilization of the port after implantation. A stay is preferably also provided to abut the wing when in the second position to keep the wing in the second position when fully deployed.Type: GrantFiled: December 21, 2011Date of Patent: April 23, 2013Assignee: Stealth Therapeutics, Inc.Inventor: Bradley J.

Publication number: 20120265146Abstract: An implantable medical device is provided which has a housing of an elongate form to minimize a size of an incision required for implantation. A stabilizing element is associated with the elongated form housing for the medical device. The stabilizing element transitions from a low profile initial form to a higher width final form to provide the medical device with a stabilized footprint after implantation. The stabilizing element is in the form of a rotating wing in one embodiment. In another embodiment, the stabilizing element is in the form of an expanding loop that can bend to extend out of side openings of a cavity within the housing, to provide such stabilization at the implantation site.

Patent number: 8097035Abstract: An implant assembly is provided for surgical implantation into an intervertebral space, such as for stabilization of vertebrae adjacent the intervertebral space during a spinal fusion procedure. The implant assembly includes a primary segment separate from a secondary segment. These segments are elongate and of sufficiently small cross-section that they can be implanted posteriorly in a minimally invasive manner. The primary segment preferably includes a tunnel and the secondary segment preferably includes a neck with the tunnel and neck sized complementally so that the segments stabilize each other where they intersect with the neck within the tunnel. The entire implant assembly is thus provided which both widens and supports the intervertebral space and is sufficiently rigid to provide adequate support for the intervertebral space as the vertebrae are fusing together.Type: GrantFiled: November 24, 2009Date of Patent: January 17, 2012Inventors: Bradley J.

Patent number: 8043247Abstract: Methods and devices are provided for shunting fluid to treat hydrocephalous, and in particular for treating normal pressure hydrocephalous, or Alzheimer's, Idiopathic Intracranial Hypertension (IIH), or any other condition in which it is necessary to drain and/or cleanse CSF. The methods and devices utilize a shunt having an inlet port, and outlet port, and a flow control component for controlling fluid flow from the inlet port to the outlet port. The shunt can be implanted at a location along or within a patient's spinal column. In one exemplary embodiment, an inlet port of a shunt can be implanted within the subarachnoid space, and an outlet port of a shunt can be implanted at a drainage site. In certain exemplary embodiments, the cerebrospinal fluid is drained into the epidural space.Type: GrantFiled: April 6, 2009Date of Patent: October 25, 2011Inventor: Bradley J. Glenn

Patent number: 7608065Abstract: A vascular access port is disclosed for subcutaneous implantation. The port is particularly adapted to be affixed to a bone to securely hold the port in position, to assist medical personnel in finding the port and to decrease a visibility of the port. The port has a chamber therein which is accessed by a needle through a septum adjacent the chamber. The chamber is placed into fluid communication with the vascular structure of the patient, such as through catheter tubing. The chamber is surrounded by a body with an outer surface which is preferably fitted with threads to facilitate secure but removable attachment of the port within a hole in the bone where the port is to be implanted.Type: GrantFiled: January 30, 2007Date of Patent: October 27, 2009Inventor: Bradley J.

Publication number: 20080255619Abstract: A three element spinal fixation system for implantation from a posterior lateral incision. The first element in the form of a translaminar cannula is adapted to be implanted along a longitudinal axis of a lamina of a vertebra. A bracket is provided as a second element with a first end removably secured to the translaminar cannula and the second end secured to vertebra inferior to an adjacent vertebra in which the translaminar cannula is implanted. The translaminar cannula has a hollow central bore which receives a third element in the form of a translaminar facet screw. The translaminar facet screw is sufficiently long to be able to pass through the central bore and out of the translaminar cannula, passing through the facet joint to fix the two vertebra at the facet joint. Both contralateral and ipsilateral fixation are thus provided with all three elements implanted from a single ipsilateral incision.Type: ApplicationFiled: April 10, 2008Publication date: October 16, 2008Inventors: Gary A.
