Infusion system having filtration device and method
An infusion system includes an infusion catheter defining a fluid passage extending between a proximal catheter end and a distal catheter end, and having a plurality of infusion ports in communication with the fluid passage and defining an infusion zone. A filtration device is provided which may be retrofitted upon the infusion catheter and includes a filter sleeve coupled to a slidable control sleeve. The filter sleeve is deformable between a first configuration having a radially contracted footprint and a second configuration having a radially expanded footprint, responsive to sliding the control sleeve over the infusion catheter such that the deformable filter sleeve buckles outwardly from the infusion catheter.
RETAINING MECHANISMS FOR PROSTHETIC VALVES
Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.
Temporary embolic protection device and medical procedure for delivery thereof
An embolic protection device, kit, and medical procedure prevent embolic material from entering into side branch vessels of the aortic arch. The device is a collapsible embolic protection device devised for temporary transvascular delivery to an aortic arch of a patient and has a protection unit that comprises a selectively permeable unit adapted to prevent embolic material from passage with a blood flow into a plurality of aortic side branch vessels at the aortic arch. The protection unit is permanently attached to a transvascular delivery unit and a first support member that is at least partly arranged at a periphery of the selectively permeable unit. In an expanded state of the device, the connection point is enclosed by the first support member or arranged at said support member.
Arthroplasty components
Systems, kits and methods for long bone arthroplasty that include arrays of humeral head prosthesis components, each having on a first side a bone articulation surface that has an overall generally hemi elliptical convex shape defined by a major axis and a minor axis, the bone articulation surface having an apex and a base that each has an non-circular elliptical cross sectional shape, the prosthesis components having on an opposite side, adjacent the base, a bone contact surface. The humeral head prosthesis components in the arrays vary from having a base with a more circular cross sectional shape to a more elongated elliptical cross sectional shape with increasing size.
EMBOLIC PROTECTION DEVICES
Embolic protection devices and methods for making and using embolic protection devices are disclosed. An embolic protection device may include an elongate filter wire having a distal end region, a filter anchor coupled to the distal end region, a filter membrane coupled to the filter anchor, and a bumper coupled to the filter anchor. The bumper may be designed to provide a tactile feedback to a clinician during delivery of the embolic protection device.
EMBOLIC IMPLANT AND METHOD OF USE
A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.
Temporary embolic protection device and medical procedure for delivery thereof
A medical procedure for positioning an embolic protection device effectively prevents material from entering with blood flow into side branch vessels of the aortic arch. The protection unit is permanently attached to a transvascular delivery unit at a connection point at a support frame that is at least partly arranged at a periphery of a selectively permeable unit. In an expanded state of the device, the connection point is enclosed by the support member or arranged at said support member.
IMPLANTABLE PROSTHESIS FOR SOFT TISSUE REPAIR
An implantable prosthesis for mending anatomical defects, including a groin hernia. The prosthesis includes a prosthetic repair patch that may be implanted in different tissue planes to mend a defect. The patch may include a medial portion configured to be positioned in a first tissue plane and a lateral portion configured to be positioned in a second tissue plane offset from the first tissue plane. The patch may include a transition region configured to extend through tissue and/or muscle, such as fascia, separating the tissue planes and transition the patch from one tissue plane to the other tissue plane. The transition region may be configured to inhibit buckling and/or bunching of the patch when implanted through the fascia. The lateral portion of the patch may have a level of stiffness that facilitates implantation of the patch in different tissue planes while inhibiting patient sensation to the implanted patch.

EMBOLECTOMY DEVICES AND METHODS FOR TREATMENT OF ACUTE ISCHEMIC STROKE CONDITION
Clot engagement element comprising bundle of unwoven fibers can be assembled to form an acute stroke treatment device. The device has the capability of forming a three dimensional filtration matrix comprising effective pores with a distribution of sizes. The bundle of fiber design allows the device to be effectively delivered into circuitous cerebral arteries to remove clot that causes stroke. The fiber bundle based filtration matrix offers the advantages of conforming to the changing inner perimeter of a blood vessel during a clot removal process and thus the capability to effectively retain and remove a clot in the vessel. The filtration matrix offers the additional advantage to trap any break-off of the clot during the removal process. A plurality of fiber bundles can be combined to form an effective clot engagement element. Supplemental engagement structure as well as mechanical treatment structure can be integrated into the stroke treatment device. The deployment of the fiber based elements can be facilitated by actuation tool. Aspiration can be employed during the clot removal process.
