Percutaneous tissue removal apparatus comprises a flexible drill shaft, a cutting tip mounted on the shaft for placement adjacent a tissue mass for cutting the tissue, means for transmitting motion to the shaft to move the cutting tip against the tissue to cut tissue fragments from the tissue, and means for removing the tissue fragments along the shaft by suction to a location outside the tissue mass while cutting. The apparatus may include means for collecting one or more selected components of the harvested tissue fragments for implantation of the fragments preferably into the body of the patient from whom they were removed. Where the tissue to be cut is bone, a cutting tip is preferably made of a polymeric material which is softer than the cortical portion of the bone, although the cutting tip may be made of a ceramic or a composite material. A second flexible shaft may be provided either within or about the flexible drill shaft. The harvested tissue fragments may be implanted in the donor patient's body.

A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs. Using the DTTL method a deeper wellbore can be drilled with larger resulting end tubulars, such as casings and production liners, than had been capable with conventional MPD applications.

A method and apparatus for anterior cruciate ligament (ACL) reconstruction using holes in bone created by retrograde cutting. A rotary cutter, mounted onto an insertion post of a tibial guide, is inserted through an anteromedial portal and the rotary cutter placed on the anatomical origin of an ACL tibial insertion. A drill pin is drilled through the tibia and advanced until it contacts and engages a cannulation in the rotary cutter on the guide. Further rotation of the drill pin disengages the rotary cutter from the guide. The retrograde drill pin is then retracted and simultaneously rotated for retrograde cutting of a socket or tunnel of desired depth in the tibia. A strand is passed through the cannulation of the drill pin into the joint. The end of the strand is retrieved from the anteromedial portal and a loop formed for subsequent graft installation. A similar technique is used to form a socket or tunnel in the femur except that a femur guide is used in place of the tibial guide. A graft of appropriate length is pulled through the anteromedial portal by the loops formed in the strands and the ends of the graft are drawn into the femoral and tibial sockets. The reconstruction is completed by securing the graft ends.

An electromagnetic pedicle awl utilizes a tightly focused time-varying magnetic flux to create a localized electromotive force (EMF) near the tip of a pedicle awl. The localized EMF creates localized eddy currents in nearby nerves which in turn excite ionic nerve channels, the excitation being detected by an electromyographic recording device. In comparison to the electrically stimulated pedicle awl of the prior art, the electromagnetic pedicle awl only excites nerves directly in front of and directly to the side of the tip. The electromagnetic pedicle awl is comprised of a tapered awl or drill tip in combination with a solid core surrounded by a solenoid. A pulsed electric current source drives the solenoid to create a time-varying magnetic field in the vicinity of the tapered tip. The awl or drill tip may be stationary with respect to the solenoid or it may rotate. The electromagnetic pedicle awl in combination with an EMG detector connected to a patient is very sensitive to the pedicle hole position with respect to adjacent nerves and reduces false placement failure.

A flow conduit having at least one orifice is placed in the vicinity of a flow source, which in one non-limiting embodiment may be a hydrocarbon reservoir. The flow pathway between the orifice and the source is temporarily blocked with a degradable barrier. Once the flow pathway is physically placed, the degradable barrier is removed under the influence of an acid, a solvent, time and / or temperature. The flow source and the flow pathways are at least partially covered (and flow blocked by) a temporary coating such as a pseudo-filter cake formed by a viscoelastic surfactant-gelled aqueous drill-in fluid, and the flow conduit is extended to the flow source. The pseudo-filter cake is removed when viscosity is reduced by an internal breaker, and flow is then allowed. The method is useful in one context of recovering hydrocarbons where the flow conduit is a telescoping sleeve or tube that contacts the borehole wall.
