Claims (21)

A fixation device for use with the medical device having an expansion member protruding from the medical device,
A retainer, a channel portion extending along an axis of the retainer and formed to receive at least a portion of the medical device, and a vertical slot along the retainer through which the medical device can pass A longitudinal slot having a width less than the diameter of the channel portion and extending toward the axis of the retainer, the expansion of the medical device in a manner that prevents the retainer from moving in the longitudinal direction of the medical device. A retainer having at least one protrusion formed to mate with the member;
A flexible fixing pad having a bottom adhesive surface and an upper surface;
The retainer is a fixing device attached to the fixing pad. The fixing device according to claim 1, wherein the axis of the channel portion is disposed at an acute angle with respect to the upper surface of the fixing pad. The channel portion of the retainer has a circular cross-sectional shape with a truncated end, and an arcuate portion greater than 180 ° about the axis of the channel portion when the medical device is received in the channel portion. The fixing device according to claim 1, wherein the fixing device surrounds at least a part of the medical instrument. The fixing device according to claim 1, wherein at least a part of the channel portion has a substantially conical shape. The fixing device according to claim 1, wherein at least one of the protrusions of the retainer includes a substantially annular ring that protrudes from the channel portion toward the axis of the retainer. The fixing device according to claim 1, wherein the cross section of the channel portion becomes gradually smaller at least at a part of its length. The fixing device according to claim 1, further comprising a second channel portion extending along the axis of the retainer, wherein the cross section of the second channel portion gradually decreases with at least a part of its length. 8. The fixation device according to claim 7, wherein the second channel portion has a substantially circular shape with a radius of curvature that substantially matches a corresponding portion of the medical device housed in the second channel portion. The retainer includes at least two protrusions, and each protrusion is sized to fit into the expansion member of the medical device so as to prevent longitudinal movement of the medical device. Fixing device. The fixing device according to claim 9, wherein at least two of the protrusions are disposed in the channel portion. The fixing device according to claim 9, wherein at least two of the protrusions are disposed outside the channel portion. The fixing device according to claim 9, wherein the protrusions are arranged next to each other along the axis so as to be positioned in parallel along the retainer for housing the medical device. The medical device having at least one member protruding from the medical device in the body;
A catheter system comprising a retainer,
The retainer is a channel extending about an axis, generally having a cross-sectional shape with a tip cut away to provide an opening substantially parallel to the axis, extending at least along the axis, the medical device being the channel A channel sized to enclose at least half of the body of the medical device when disposed therein, and at least one protrusion extending toward the axis and generally within the channel, the medical device Is configured to contact at least one of the members of the medical device when inserted into the retainer with at least one of the members disposed in the channel, the longitudinal movement of the medical device within the retainer A catheter system including at least one protrusion sized to impede. 14. The catheter system of claim 13, wherein the channel has a generally circular shape with a radius of curvature that substantially matches the conical shape of the body of the medical device. The channel comprises a first channel portion and a second channel portion, wherein the first and second channel portions are on a matching portion of the body of the medical device housed in the respective channel portion. 14. The catheter system of claim 13, having a generally arcuate shape with a substantially matching radius of curvature. The catheter system of claim 15, wherein at least a portion of one of the first and second channel portions has a generally frustoconical shape. A fixation system for an elongated medical device comprising:
A body defined for the axis, and
A retainer including a first side and a second side that together define a space large enough to accommodate a portion of the medical device;
The retainer includes a protrusion that accommodates at least a part of the medical device in the space and extends in a substantially normal direction with respect to the axis of the retainer,
The protrusion is formed by the retainer so as to cooperate with the medical device in a manner that substantially prevents axial movement of the medical device. At least a portion of the retainer has a cross-sectional shape with a tip cut away to provide an opening parallel to the axis, and the at least a portion of the retainer has an arcuate shape greater than 180 ° around the axis. The fixation system according to claim 17, wherein the fixation system is sized to surround at least a part of the medical device. The fixing system according to claim 17, wherein the protrusion of the retainer includes a substantially annular ring extending from the first and second sides toward the axis of the retainer. The fixing system according to claim 17, wherein the defined space has a substantially frustoconical shape with a tip cut off along one surface. 18. The fixation system of claim 17, wherein the defined space has a generally arcuate shape with a radius of curvature that substantially matches at least a portion of the medical device.
