A medical device insertion system, and a method of using the system, to mate trocars inside a patient during a medical procedure, the system including a first trocar having a first end to insert into a patient, and a second end at which a first user control is provided, and a second trocar having a first end to insert into a patient, and a second end at which a second user control is provided, wherein the respective first ends of the first and second trocars are formed so as to mate to one another inside the patient to form a continuous path between the respective second ends.

Multiple section trocar

A gravitational pressure regulating valve to regulate fluid flow of a patient, including a fluid chamber having an inlet port to receive a bodily fluid and an outlet port to discharge received bodily fluid, the fluid chamber including a first chamber configured to capture a non-buoyant member therein and to guide the non-buoyant member along a longitudinal axis of the first chamber to facilitate bi-directional reciprocating movement of the non-buoyant member to and from the inlet port, and a second chamber configured to capture one or more buoyant members therein such that when the second chamber is filled with bodily fluid, at least one of the buoyant members applies a resolved buoyant pressure from a buoyant force of the one or more buoyant members in opposition to an inlet pressure of fluid at the inlet port.

Pressure regulating buoyant valve for a shunt system

Systems and methods to regulate flow of bodily fluids, such as cerebrospinal fluid (CSF), including a fluid chamber, an inlet port to receive the bodily fluid into the fluid chamber, an outlet port to remove the bodily fluid from the chamber, and a pressure element to regulate the amount of fluid flowing from the inlet port to the outlet port based on a pressure of the bodily fluid against an absolute pressure reference.

Systems and methods of controlling flow of bodily fluids

A gravitational pressure regulating valve to regulate fluid flow of a patient, including a fluid chamber having an inlet port to receive a bodily fluid and an outlet port to discharge the received bodily fluid, and an opposing force member in the fluid chamber to oppose a first force of the fluid flow at the inlet port with a second force that varies according to changes in gravitational alignment.
