International Classification:

G01M 3/04

US Classification:

73 407

Abstract:

An implantable pump and methods for detecting leaks in an implantable pump are provided. In one embodiment, the implantable drug pump includes a housing having at least one inlet port and an outlet port formed therein. The outlet port is adapted to communicate with a catheter for delivering fluid to a patient's body, and the inlet port(s) are effective to deliver fluid into the housing. The housing further includes at least one reservoir disposed therein and effective to contain a fluid. In use, the pump preferably includes a fluid having one or more drugs disposed in at least one of the reservoirs, and a radiolucent fluid disposed in one of the reservoirs. A user programmable control mechanism is coupled to the drug pump and is effective to selectively control movement of the valves between the open and closed positions.

International Classification:

A61B 1/32

US Classification:

600215

Abstract:

A blade extending tower for setting blade depth on retractors having telescoping or extending blades. The blade extending tower features a base, a column extending from the base, and mating features on the column configured to engage the blades of a retractor to extend the blades to a desired blade depth. Blade depth of the retractor is set buy sliding the retractor onto the blade extending tower such that the mating features of the blade extending tower engage the blades or the retractor, stopping the blades progression while the rest of the retractor continues along the length of the column. Thus the blades of the retractor are extended from the retractor to a depth determined by the configuration of the blade extending tower.

International Classification:

A61B 17/58

US Classification:

606 86A, 606190, 600203

Abstract:

A minimally invasive surgical method includes inserting a first port that defines a first pathway to a first vertebra, advancing a first anchor through the first port to the first vertebra, inserting a second port that defines a second pathway to a second vertebra, advancing a second anchor through the second port to the second vertebra, positioning a first end of a fixation element in the first port, and advancing the first end of the fixation element subcutaneously through an opening in the first port and an opening in second port to the second anchor. A surgical access port includes a proximal end, a distal end, and a sidewall defining a lumen extending from the proximal end to the distal end. The port may include a first opening formed in the sidewall that defines a passageway for medical hardware from the lumen to external to the port.

International Classification:

A61B 1/32

US Classification:

600206, 600208, 600233

Abstract:

The present invention provides a non-rigid retractor for providing access to a surgical site, such as a patient's spine, during a surgical process. When used in spinal surgery, the non-rigid retractor allows a surgeon to operate on one or more spinal levels. The non-rigid retractor includes at least one flexible strap anchored at a first end to the spine or other internal body part at the surgical site. The body of the at least one flexible strap extends from a skin incision and is anchored at a second location external to the body to retract skin and muscle from the surgical site, allowing adequate visualization of the surgical site and providing access for implants and surgical instruments to pass through the retractor and into the surgical site.

US Classification:

606 86A, 606264, 606265

Abstract:

The present invention provides minimally invasive devices and methods for delivering a spinal connector to one or more spinal anchor sites in a patient's spinal column. In one embodiment, a spinal implant and access device is provided that includes a U-shaped receiver member, a bone-engaging member, and an extension member. The U-shaped receiver member can have a recess formed therein that is adapted to seat a spinal connector. The bone-engaging member can extend distally from the receiver member and it can be adapted to engage bone to thereby mate the receiver member to bone. The extension member can extend proximally from the receiver member and it can include a frangible portion formed thereon that is adapted to break when a predetermined force is applied thereto thereby allowing at least a portion of the extension member to be separated from the receiver member.
