A delivery system for an intracorporeal device includes a sheath defining one or more lumens shaped to receive a delivery catheter or shaft and a guidewire. The system may include a delivery shaft having a distal coupling feature adapted to releasably couple with a proximal coupling feature of the intracorporeal device. The delivery system may further include a hub through which the delivery shaft and guidewire are passed. The delivery shaft may be coupled to a feature, such as a knob, that enables manipulation of the delivery shaft to decouple the distal fixation feature from the proximal fixation feature of the intracorporeal device in order to deploy the intracorporeal device within a patient.

A system for attachment of a device to a bone is provided. The system includes an internal axial rod with a proximal and distal end that is configured to be inserted and secured into a bone cavity’s distal end. The system can also include an internal-external transfer rod with a proximal and distal end mounted into the distal end of the axial rod and a central channel extending through the transfer rod from the proximal end to the distal end and a plurality of attachment rings for attaching at least one tissue or muscle group to the transfer rod. The system also includes a bio-compatible and bio-occlusive artificial membranes (BIOCAMS) lamina, wherein the lamina includes either a polyetheretherketone (PEEK) mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissue, allogenic tissue, a collagen/hyaluronic acid-based tissue, or connective tissue biosynthetic substrate material suitable as webbing.

Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. A system for processing cerebrospinal fluid is disclosed. The system may include a catheter having a proximal subassembly and a distal subassembly. A pump and filtration system may be coupled to the catheter. An infusion lumen for infusing cerebrospinal fluid filtered by the pump and filtration system may be defined along the distal subassembly. The distal subassembly may define a plurality of infusion openings in fluid communication with the infusion lumen. The infusion openings may increase in size distally along the distal subassembly.

The present invention is directed to a dual lumen cannula configured to be inserted into a patient's body as simple as a single lumen cannula. The dual lumen cannula includes at least one inner lumen configured to be inserted into an outer lumen and connected via an inner lumen connection unit and an outer unit connection unit. Embodiments of the presenting invention further allow for the connection of at least one flow router to the other end of the inner lumen connection unit. When installed, the outer lumen is first inserted into the patient's body, followed by the insertion of the inner lumen into the outer lumen of the already cannulated patient until the inner lumen connector unit is in coupling contact with the outer lumen connector unit. Advantages of the inventive cannula presented herein include, among other things, reduction of external forces on the dual lumen cannula.

A medical device for stone management comprises a catheter comprising a proximal end, a distal end, and a first lumen and a second lumen disposed therethrough. A handle assembly is interconnected with the proximal end of the catheter, the handle assembly comprising a body defining an interior cavity, a first section and a second section. An interior passageway is disposed within the interior cavity and in fluid communication with the first lumen of the catheter. A valve assembly interconnected with the interior passageway. An actuator assembly is engaged with the valve assembly, the actuator having a first position and a second position. A vacuum port is in communication with the interior passageway and positioned on the second section of the handle. The second section of the handle forms an angle with respect to the first section of the handle.

A bi-directional perfusion cannula comprising a flexible elongated tube 1 for insertion into an artery having a first aperture 3 at a distal end and a second aperture 4 formed rearward of the first aperture, the elongated tube can be bent in correspondence of the second aperture to orient it in a direction opposite to the insertion direction. The cannula is provided with a tape 5 having a first end portion shaped as a ring, fixed on an outer surface of the elongated tube, and a second end portion opposite to the first end portion either coupled to or being integral with a belt 7 defining a strap 11 with holes 12 and at least a prong 13 integral with the strap and configured to engage a respective hole, wherein the belt is configured to be tightened around an outer surface of the artery.

A catheter placement system having a catheter and a skin nicking device that includes a blade configured to nick the skin of a patient adjacent a catheter insertion site. The catheter includes a multi-luminal catheter tube coupled with multiple extension legs. The catheter tube includes a diameter transitioning section disposed between two sections of the catheter tube having different diameters. The skin nicking device is disposed within a lumen such that a blade at the distal of the skin nicking device protrudes from an aperture of the lumen. The skin nicking device is positionable and rotatable within lumen and removable from the lumen. The skin nicking device includes an elongate body that may include rigid portions and/or flexible portions.

A delivery device for delivering an instrument through an intravenous catheter may include a housing, a rotary element disposed within the housing, and the instrument. In some embodiments, the rotary element may include a groove, which may extend around at least a portion of a circumference of the rotary element. In some embodiments, the instrument may be disposed within the groove and/or between the rotary element and the housing. In some embodiments, in response to rotation of the rotary element with respect to the housing, the instrument may be advanced distally through a port of the housing. In some embodiments, the instrument may include a guidewire, a probe, tubing, or a light tube.

A catheter for an extracorporeal blood circulator disperses a flow of blood flowing out from a blood feeding hole to reduce the impact of blood collision on a living organ. The catheter 60 includes a blood feeding lumen 61 extending in an axial direction and a blood feeding hole 63 communicating with a distal end of the blood feeding lumen, and a side portion 63a of the blood feeding hole on the proximal side facing the blood feeding lumen is cut out to a bottom portion 63b of the blood feeding hole.

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.
