Patent number: 9232921Abstract: A system and method for intracranial access is disclosed. In particular, a drill stop is shown providing a way to control the penetration of a drill bit as an access hole into the brain is being formed. Access to a desired location is achieved using a catheter guide device. Also disclosed is a mechanism by which multiple diagnostic and treatment devices can be placed at a desired location in brain tissue without the need for more than one access hole. A drainage catheter is disclosed with a mechanism to allow both drainage and to allow intracranial pressure measurement.Type: GrantFiled: June 2, 2010Date of Patent: January 12, 2016Assignee: InnerSpace Medical, Inc.Inventors: Donald E. Bobo, Sr., James Gerg

Patent number: 7654967Abstract: The present invention provides a device for efficiently coupling a pressure monitoring device to a pressure transducer. In addition, the present invention reduces or eliminates the likelihood air will be unintentionally injected into the pressure monitoring device while connecting the pressure monitoring device to a pressure transducer. In one embodiment, the present invention includes a pressure monitoring coupler comprising a sealing member and a device body. The sealing member comprises a sealing flange connected to an engagement member. The engagement member includes a first and second O-ring positioned thereon. The device body comprises a pressurizing lumen and an intersecting monitoring lumen in communication with a receiving aperture. During use, a pressure monitoring catheter is inserted into a patient's tissue. The pressure monitoring catheter and a transducer are connected to the device body of the present invention.Type: GrantFiled: March 7, 2007Date of Patent: February 2, 2010Assignee: InnerSpace Medical, Inc.Inventor: Donald E. Bobo, Sr.

Patent number: 6673022Abstract: A catheter has a pressure sensitive bladder at a distal end and a pressure transducer at a proximal end with the proximal end attached to a mammalian body and the bladder inserted within the mammalian body. The bladder partially filled with a gas responds to pressure changes within the body and the pressure transducer senses the changes via gaseous communication with the bladder. In one embodiment, the bladder is inserted in a human brain with the transducer mounted on a bolt affixed to the skull. Initial dissection of the brain tissue is effected by over-inflation of the bladder by a manual piston pump or a blunt ended slender rod. The transducer may be mounted on a bolt inserted within a hole drilled in the skull. An antimicrobial agent may be dispersed from openings in a seal between the bolt and the skull, from a porous seal, or from a ribbed or threaded outer surface of the bolt.Type: GrantFiled: July 18, 2000Date of Patent: January 6, 2004Assignee: InnerSpace Medical, Inc.Inventors: Donald Bobo, James Gerg
