The system is well-suited for advancing a prosthetic valve or other medical device through an introducer sheath having a relatively small inner diameter. The introducer sheath may be formed with a tapered proximal end portion for receiving the prosthetic valve and for reducing a diameter of the prosthetic valve during advancement therethrough.

The present invention relates to a transdermal drug delivery system comprising a dermal drug delivery patch and a heating element compartment securable to the dermal drug delivery patch. A freely transferrable heating element is securable within the heating element compartment. A drug can be administered transdermally using the present invention by placing the dermal drug delivery patch upon a patient's skin at an administration site. A heating element compartment is secured to the dermal drug delivery patch and a freely transferrable heating element is placed within the heating element compartment. The heating element provides controlled heat to the dermal drug patch and the patient's skin aid thereby improves dermal drug administration.

The present invention relates to circular anastomosis stapler and kits comprising reinforcing buttress materials and fixation tools that are slidably installed on the anvil shaft of such staplers which provides a temporary mechanical fixation of a reinforcing buttress to the anvil surface of a circular stapler during the insertion of the anvil into the tubular tissue. When the anvil, loaded with the buttress, is in the desired location, the fixation tool is pulled back along the anvil shaft and removed. The shaft is then connected to the stapling head and the stapling is performed. The present invention also relates to methods for using the kits and devices therein.

A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent (10) with a prosthetic heart valve (11) at its proximal end is introducible into a patient's main artery. With the objective of optimizing such a device to the extent that the prosthetic heart valve (11) can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis (11) in the patient's ventricle, the device includes a self-expanding positioning stent (20) introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent (10) so that the two stents respectively interact in their expanded states such that the heart valve stent (10) is held by the positioning stent (20) in a position in the patient's aorta relative the heart valve predefinable by the positioning stent (20).

A spinal implant may be used to stabilize a portion of a spine. The implant may promote bone growth between adjacent vertebrae that fuses the vertebrae together. An implant may include an opening through a height of a body of the implant. The body of the implant may include curved sides. A top and / or a bottom of the implant may include protrusions that contact and / or engage vertebral surfaces to prevent backout of the implant from the disc space. A variety of instruments may be used to prepare a disc space and insert an implant. The instruments may include, but are not limited to, a distractor, a rasp, and one or more guides. The implant and instruments may be supplied in an instrument kit.

A linking element for a spinal fixing system is designed to link at least two implantable connecting assemblies. The linking element consists at least partly of a support made of polymeric material and a rod, bent or not, substantially coaxial with the support. The invention also concerns a spinal fixing system comprising at least two implantable connecting assemblies linked by at least one linking element of the invention.

An intervertebral implant for fusing vertebrae is disclosed. The implant has a body with curved, substantially parallel posterior and anterior faces separated by two narrow implant ends, superior and inferior faces having a plurality of undulating surfaces for contacting upper and lower vertebral endplates, and at least one depression in the anterior or posterior face for engagement by an insertion tool, at least two vertical through-channels extending through the implant from the superior face to the inferior face, a chamfer on the superior and inferior surfaces at one of the narrow implant ends, and a beveled edge along a perimeter of the superior and inferior faces. The arcuate implant configuration and the chamfers on the superior and inferior faces at the narrow end facilitate insertion of the implant from a transforaminal approach into a symmetric position about the midline of the spine so that a single implant provides balanced support to the spinal column. The implant may include radiopaque markers extending through the thickness of the implant to indicate the location and size of the implant. The implant may be formed of a plurality of interconnecting bodies assembled to form a single unit. An implantation kit and method are also disclosed.

A bone member fastener for closing a craniotomy includes a cap and a base interconnected by a narrow cylindrical collar. The cap has an externally threaded stud that screws into an internally threaded bore of the collar, thereby allowing the cap and base to be brought into clamping engagement against the internal and external faces of a bone plate and surrounding bone. In a particularly disclosed embodiment, the base of the fastener is placed below a craniotomy hole with the collar projecting into the hole, and the stud of the cap is screwed into the bore of the base from above the hole to clamp a bone flap against the surrounding cranium. This device provides a method of quickly and securely replacing a bone cover into a craniotomy. The distance between the cap and base can be selected by how far the threaded stud of the cap is advanced into the internally threaded collar. The fastener is therefore adaptable for use in several regions of the skull having various thicknesses. An insertion tool with a long handle permits safe and convenient placement of the base between the brain and the internal face of the bone plate. Some disclosed embodiments of the fastener have a cap and base that conform to the curved surface of the skull, for example by having an arcuate shape or flexible members that conform to the curvature of the bone plate and surrounding cranial bone as the fastener is tightened.

An apparatus for sealing a passage through tissue includes an elongate shaft and a cylindrical plug disposed on a distal end of the shaft, the plug including a helical thread on its outer surface. Intestinal submucosa may be secured to the plug, e.g., in a cavity in its distal end, that may be delivered into the passage. Alternatively, the plug may be formed from a bioabsorbable material and may be released from the shaft within the passage. The plug is threaded into the passage, thereby engaging the tissue to seal the passage. The shaft is rotated until it engages a blood vessel within the tissue while monitoring blood flow through the vessel. The shaft is rotated to thread the plug into the passage until blood flow ceases through the vessel, whereupon rotation of the shaft is reversed to back the plug until blood flow through the vessel resumes.

Disclosed herein are endoscopic gastric restriction devices and methods. In one embodiment, the device generally includes a shaft having an end effector on a distal end thereof. The end effector includes several elongate segments that are coupled to one another and include opposed troughs formed therein. Each trough is configured to suction and pull tissue into the trough, as well as hold a fastener that can be delivered to tissue disposed within the trough. As a result, the end effector can deliver multiple fasteners to opposed walls of tissue. As the fasteners are delivered into tissue, the segments can be detached from the device, so that the end effector remains in the tissue. Over time, the end effector can be absorbed and / or dissolve, leaving the fasteners behind.

A manipulator for use in medical procedures can manipulate a medical tool with one or more degrees of freedom with respect to a patient.
