A blood flow controlling apparatus, which is configured to be implanted into a blood circulatory system of a patient, comprises an anchoring means, which is arranged to fix the position of the apparatus in the blood circulatory system, and a valve means being connected to the anchoring means. The valve means is configured to be arranged within the blood circulatory system and is configured to be extendable in a direction transverse to blood flow in order to make contact with native tissue when inserted in the blood circulatory system. The valve means is further configured to release said contact as a result of being exposed to blood flow in a permitted direction.

An improved intravascular blood pump system (10) and related methods involving the broad inventive concept of equipping the intravascular blood pump (12) with guiding features such that the intravascular blood pump can be selectively positioned at a predetermined location within the circulatory system of a patient.

A multi-leaflet valve adapted to serve as a prosthesis for diseased native valve of a mammal is incorporated in self-expandable or inflatable endovascular stents or stents to form a combination which is introduced on a catheter with a guide wire into the circulatory system of the mammal to replace the diseased native valve. Once the combination is at the desired location the stent is caused to expand and affix itself to the patient's vessel wall. The prosthetic valve has the shape of a truncated cone that has an inflow and an outflow orifice with leaflets forming the outflow orifice and forming a plurality of commissures. A first flexible circular support is affixed in a substantially circular fashion around the truncated cone in proximity of the inflow orifice, and a second flexible circular support is affixed at the location of the commissures to form a circle around the truncated cone in proximity of the outflow orifice. The circular supports maintain the shape of the valve during the surgical implantation procedure and thereafter.

Organs and other tissue structures are isolated and perfused with a therapeutic agent. Isolation is effected by endovascularly positioning catheters having occlusion balloons within the arteries or other blood vessels which supply blood to the organ. Similarly, blood flow from the organ back to the patient's circulatory system is blocked by endovascularly positioning one or more catheters carrying occlusion members within the veins or other blood vessels leading from the organ. The therapeutic agent may then be perfused through the organ in either an antegrade or retrograde fashion using the endovascularly positioned catheters while maintaining isolation.

A system for inducing cardioplegic arrest and performing an endovascular procedure within the heart or blood vessels of a patient. An endoaortic partitioning catheter has an inflatable balloon which occludes the ascending aorta when inflated. Cardioplegic fluid may be infused through a lumen of the endoaortic partitioning catheter to stop the heart while the patient's circulatory system is supported on cardiopulmonary bypass. One or more endovascular devices are introduced through an internal lumen of the endoaortic partitioning catheter to perform a diagnostic or therapeutic endovascular procedure within the heart or blood vessels of the patient. Surgical procedures such as coronary artery bypass surgery or heart valve replacement may be performed in conjunction with the endovascular procedure while the heart is stopped. Embodiments of the system are described for performing: fiberoptic angioscopy of structures within the heart and its blood vessels, valvuloplasty for correction of valvular stenosis in the aortic or mitral valve of the heart, angioplasty for therapeutic dilatation of coronary artery stenoses, coronary stenting for dilatation and stenting of coronary artery stenoses, atherectomy or endarterectomy for removal of atheromatous material from within coronary artery stenoses, intravascular ultrasonic imaging for observation of structures and diagnosis of disease conditions within the heart and its associated blood vessels, fiberoptic laser angioplasty for removal of atheromatous material from within coronary artery stenoses, transmyocardial revascularization using a side-firing fiberoptic laser catheter from within the chambers of the heart, and electrophysiological mapping and ablation for diagnosing and treating electrophysiological conditions of the heart.

Cells derived from postpartum tissue are disclosed along with methods for their therapeutic use in diseases of the heart or circulatory system are disclosed. Cells may be used therapeuticall in either differentiated or undifferentiated forms, in homogenous cultures, or as populations with other cells, and in conjunction with other bioactive factors.

The present invention relates to heterospecific polypeptide constructs comprising at least one single domain antibody directed against a therapeutic and / or diagnostic target and at least one single domain antibody directed against a serum protein, said construct having a prolonged lifetime in biological circulatory systems. The invention further relates to methods for stabilising VHHs in biological circulatory systems.

A medical imaging system provides simultaneous rendering of visible light and fluorescent images. The system may employ dyes in a small-molecule form that remains in a subject's blood stream for several minutes, allowing real-time imaging of the subject's circulatory system superimposed upon a conventional, visible light image of the subject. The system may also employ dyes or other fluorescent substances associated with antibodies, antibody fragments, or ligands that accumulate within a region of diagnostic significance. In one embodiment, the system provides an excitation light source to excite the fluorescent substance and a visible light source for general illumination within the same optical guide that is used to capture images. In another embodiment, the system is configured for use in open surgical procedures by providing an operating area that is closed to ambient light. More broadly, the systems described herein may be used in imaging applications where a visible light image may be usefully supplemented by an image formed from fluorescent emissions from a fluorescent substance that marks areas of functional interest.

A catheter integral with a valved needle-free connector provides a safety catheter device configured to receive a blunt cannula and sharp needle forming an insertion mechanism. The sharp needle is mounted within a needle tube and a control handle is used to slide the sharp needle out of and into the protective needle tube. When the insertion mechanism is mounted to the connector and the control handle is used to slide the sharp needle out of the tube, a blunt cannula first moves into contact with and enters the bore of the valve mechanism of the connector opening it and protecting it from damage that may be caused by the sharp needle. The sharp needle is then extended through the connector and extends out the distal end of the catheter so that a venipuncture procedure may be performed to properly locate the catheter in the patient's circulatory system. Once located, the needle may be retracted into the insertion mechanism, the insertion mechanism disconnected from the connector, and discarded.
